Step 1: Turn off gas and power
Turn Off Gas and Power
Actions
1. Locate the gas shutoff valve behind the range – it will be positioned on the wall or floor approximately 6-12 inches behind the appliance, connected to a flexible gas line that runs to the back of the range.
2. Turn the gas shutoff valve handle 90 degrees clockwise (perpendicular to the gas pipe) until it stops – the handle should now point across the pipe rather than along it, indicating the closed position.
3. Verify the gas is off by attempting to ignite one of the cooktop burners – turn a burner knob to “high” and listen for clicking without flame ignition, confirming no gas flow.
4. Locate your home’s electrical panel (breaker box) and identify the breaker labeled for the kitchen range – it will typically be a single 15-20 amp breaker (gas ranges use less power than electric ranges).
5. Flip the range breaker to the “OFF” position – the switch will move to the opposite side and you may hear a click.
6. Return to the range and verify power is off by attempting to turn on the oven using the control panel – the display should remain dark and unresponsive.
7. If the range has a power cord plugged into a wall outlet behind the unit (rather than hardwired), pull the range forward approximately 12 inches to access the rear.
8. Unplug the power cord from the wall outlet by gripping the plug body (not the cord) and pulling straight out with firm pressure.
9. If the range is hardwired (no visible plug), leave the breaker in the “OFF” position and do not disconnect any wires at this stage – you will work with the breaker off throughout the repair.
Troubleshooting Tips
**Gas valve won’t turn**: If the shutoff valve is seized and won’t rotate, spray the valve stem with penetrating oil (WD-40 or PB Blaster), wait 5 minutes, then attempt to turn while applying steady pressure – never force it. If still stuck, turn off gas at the main meter and contact a plumber.
**Can’t identify correct breaker**: Turn on the oven display so it’s illuminated, then flip breakers one at a time until the display goes dark – this identifies the correct breaker. Mark it with tape labeled “Range” for future reference.
**Range won’t pull forward**: Check for anti-tip bracket engagement at the rear – slide your hand behind the range top rear edge and feel for a metal bracket holding the range down. Lift the rear of the range slightly (1-2 inches) while pulling forward to disengage the bracket.
**Gas smell after closing valve**: A faint residual gas smell lasting 2-3 minutes is normal as remaining gas in the line dissipates. If the smell persists beyond 5 minutes or intensifies, evacuate the home immediately and call your gas company emergency line – do not proceed with the repair.
**Hardwired connection visible at back**: Do not cut or disconnect any wires at the range connection point – working with the breaker off provides adequate safety for this repair.
Step 2: Access valve from rear panel
Access Valve from Rear Panel
1. Grip the range on both sides at the front corners, then pull it forward away from the wall approximately 3 feet to provide working space behind the unit.
2. Locate the rear access panel on the back of the range—it’s a rectangular metal panel measuring approximately 18 inches wide by 12 inches tall, positioned in the center of the back, about 8 inches up from the floor.
3. Identify the 6 Phillips-head screws securing the rear panel—3 screws across the top edge and 3 across the bottom edge, spaced evenly approximately 6 inches apart.
4. Using a Phillips #2 screwdriver, remove all 6 screws by turning counterclockwise. Store the screws in a container as you’ll need them for reassembly.
5. Grip the panel at the top center and pull it straight back toward you approximately 1 inch, then lift upward to unhook it from the internal brackets. Set the panel aside.
6. Look inside the cavity—you’ll see the oven safety valve located on the right side, approximately 4 inches from the top of the opening. It’s a brass-colored cylindrical component approximately 3 inches long with a gas line connected to one end.
7. Identify the wire bundle running vertically along the left side of the cavity—this contains 3 wires: one red wire, one white wire with a black stripe, and one bare copper ground wire. These wires power the igniter circuit.
8. Push the wire bundle approximately 2 inches to the left to move it out of your working area. The wires have approximately 4 inches of slack, so no tension should be present when moved.
9. Locate the gas supply line—a rigid copper or steel tube approximately 1/4 inch diameter—entering the valve from below. This line does not need to be disconnected yet but note its position.
10. Check for a second wire harness near the valve itself—you’ll see a 2-wire connector with one orange wire and one white wire. These connect directly to the safety valve’s coil terminals. Do not disconnect these yet; you’re only accessing the area in this step.
Troubleshooting Tips for This Step:
**If the rear panel won’t release after removing screws:** Check the bottom edge for hidden clips. Push the panel down slightly (approximately 1/4 inch) before pulling back.
**If wires appear tight when moving them:** Trace the wire bundle upward to locate any zip ties or clips holding them in place. Release one clip at the top of the cavity (approximately 2 inches below the range top) using needle-nose pliers to squeeze the clip open.
**If you see different colored wires:** Some production runs used a brown wire instead of the white-with-black-stripe wire. Function remains identical—both are neutral wires in the igniter circuit.
**If the valve is not visible in the expected location:** Look 2-3 inches lower—on early 2015 models, the valve sits closer to the burner manifold. The brass cylindrical shape remains consistent across all variations.
Step 3: Disconnect gas line carefully
Disconnect Gas Line Carefully
1. Locate the gas supply line connection point at the back lower left of the range, approximately 4 inches from the floor and 3 inches from the left side panel.
2. Turn off the manual gas shut-off valve by rotating the handle 90 degrees clockwise until it’s perpendicular to the gas pipe. The valve is located on the gas supply line where it enters the range, typically 6-12 inches behind the unit.
3. Use a 1/2-inch open-end wrench to hold the stationary fitting on the range side (closest to the appliance) to prevent it from rotating.
4. With a second 1/2-inch open-end wrench, grip the coupling nut that connects the flexible gas line to the range fitting. Turn this nut counterclockwise while keeping the stationary fitting steady with your first wrench.
5. Continue turning the coupling nut 6-8 full rotations until it completely separates from the threaded fitting. You will feel the connection loosen after the first 2-3 turns.
6. Pull the flexible gas line straight back away from the range connection point, moving it 8-10 inches away to provide clear working space.
7. Inspect the threaded fitting on the range—you’ll see a brass or steel hex-shaped connector protruding approximately 1 inch from the gas valve body.
8. Check for a yellow or white wire bundle (typically 3-4 wires) running near the gas connection point along the left side panel. Push this wire bundle 2 inches toward the front of the range to prevent interference during valve removal.
9. Place a small container or rag beneath the disconnected fitting to catch any residual gas droplets or debris that may release when you remove the safety valve.
Troubleshooting Tips for This Step
**If the coupling nut won’t turn:** Apply penetrating oil around the threads and wait 10 minutes. The threads may be corroded. Use a larger 12-inch wrench for better leverage, but do not force—excessive torque can crack the gas valve body.
**If you smell gas after disconnecting:** This is normal—a small amount of residual gas (1-2 teaspoons) may remain in the line between the shut-off valve and connection point. Open nearby windows and allow 5 minutes for dissipation. The smell should completely disappear within this time.
**If the stationary fitting rotates despite holding it:** The entire gas valve assembly may be loose inside the range. Stop immediately and tighten the valve mounting bracket (two 1/4-inch hex screws located on top of the valve body) before continuing.
**How to verify the gas is fully shut off:** After turning the valve perpendicular, attempt to gently push the coupling nut back onto the threads—if gas is still flowing, you’ll hear a faint hissing sound. No sound means the valve is properly closed.
**If coupling nut threads appear damaged:** Inspect for cross-threading (misaligned grooves in the metal). If more than 2 thread grooves are visibly damaged, you must replace both the coupling nut and the flexible gas line before reassembly to prevent gas leaks.
Step 4: Disconnect wire harness
Disconnect Wire Harness from Oven Safety Valve
1. Locate the wire harness connector attached to the oven safety valve. The valve is positioned on the left side of the burner assembly, approximately 8 inches from the back wall. You’ll see a white plastic connector with 2 wires attached.
2. Identify the two wires entering the connector: both wires are typically white or cream-colored with brass-colored spade terminals inside the connector. These wires carry low voltage (millivolts) from the thermocouple to the safety valve coil.
3. Examine the white plastic connector housing. It’s rectangular, measuring approximately 1 inch long by 0.5 inches wide, with the wires entering from one end.
4. Grip the connector housing firmly between your thumb and index finger—not the wires themselves. The housing has small ridges on the sides for gripping.
5. Pull the connector straight away from the safety valve terminals using steady pressure. Apply 3-5 pounds of force directly backward. The connector should slide off without twisting. Do not pull on the wires, as this can damage the crimp connections inside the connector.
6. If the connector resists removal, check for a small locking tab on the underside of the connector body. Press this tab down with your thumbnail while pulling the connector backward.
7. Once removed, examine the two brass spade terminals inside the connector housing. They should be shiny and free of corrosion. If you see green or white buildup, use fine-grit sandpaper (220-grit) to clean the terminals before reconnecting.
8. Set the disconnected wire harness to the right side of the oven cavity, resting it against the burner tube so it doesn’t fall into the burner box below.

Troubleshooting Tips for Wire Harness Disconnection
**If one or both wires pull out of the connector housing:** – Note which terminal position each wire occupied (left or right when viewing the connector from the front). – The wires are interchangeable on safety valves—polarity doesn’t matter for this millivolt circuit. – To reinsert a wire, push the brass spade terminal firmly into the connector slot until it clicks. You should feel resistance, then a distinct snap as the terminal seats fully. – Tug gently on the wire with 2-3 pounds of force—it should not pull free if properly inserted.
**If wires appear damaged or corroded:** – Examine the brass spade terminals. If corroded beyond cleaning, you’ll need to cut the wire 2 inches from the terminal, strip 1/4 inch of insulation, and crimp on new female spade terminals (size: 0.25-inch or 6.3mm). – Replacement terminals are available at hardware stores; use a crimping tool, not pliers, for a secure connection.
**Verification after disconnection:** – Both wires should remain in the connector housing with brass terminals visible. – The safety valve terminals on the valve body should be exposed and clean. – The connector housing should show no cracks or melting damage. Replace the entire wire harness if the housing is damaged.
Step 5: Remove mounting screws
Remove Mounting Screws
1. Locate the two mounting screws securing the safety valve to the burner assembly frame – one screw is positioned on the left side of the valve body approximately 1 inch from the gas inlet pipe, and one screw is on the right side approximately 1 inch from the outlet pipe connection.
2. Identify any wire harness bundles running near the mounting screws – you’ll typically see a black vinyl-wrapped wire bundle containing 4-6 wires running parallel to the burner tube, positioned about 2 inches above the valve body.
3. Push the wire bundle upward and to the right, away from the left mounting screw, creating a 3-4 inch clearance – the bundle has slack built into it and will move easily without resistance.
4. Select a 5/16-inch nut driver or socket wrench for the mounting screws – these are hex-head sheet metal screws, not Phillips screws.
5. Place the nut driver on the left mounting screw and turn counterclockwise 8-10 full rotations until the screw releases completely from the mounting bracket – the screw threads into a captive nut welded to the burner frame.
6. Remove the screw fully and set it aside in your parts container – the screw length is approximately 3/4 inch with sheet metal threading.
7. Move to the right mounting screw and repeat the removal process – turn counterclockwise 8-10 full rotations until completely free.
8. Support the safety valve body with your left hand as you remove the right screw, preventing the valve from dropping or pivoting forward, which could stress the gas pipe connection.
9. Once both screws are removed, the safety valve will be held in position only by the gas inlet pipe connection – the valve body can now pivot slightly but should not be pulled away from the pipe yet.
10. Inspect both screw holes in the mounting bracket – you should see clean threaded holes approximately 1/4 inch deep with no rust or debris.
Troubleshooting This Step
**If the screws won’t turn:** The mounting screws may have thread-locking compound applied. Apply penetrating oil (WD-40 or equivalent) to the screw threads, wait 5 minutes, then attempt removal again with firm downward pressure on the nut driver to prevent cam-out.
**If a screw strips or rounds off:** Switch to a 6-point socket instead of a 12-point socket for better grip. If already stripped, use locking pliers (Vise-Grips) clamped onto the screw head – turn counterclockwise while pulling outward with 10-15 pounds of force.
**If the wire bundle won’t move clear:** Locate the plastic wire tie securing the bundle to the frame rail approximately 6 inches behind the valve – cut this tie with wire cutters to gain additional slack, then reposition the bundle.
**If the valve drops when screws are removed:** The valve weighing approximately 8 ounces will pivot forward on the gas pipe – this is normal and won’t damage the pipe connection, but support it to prevent strain on the thermocouple wires still connected at this point.
Step 6: Install new valve
Install New Valve
1. Remove the new oven safety valve from its packaging and locate the two threaded mounting holes on the valve body – they’re positioned approximately 2.5 inches apart on the flat mounting flange.
2. Position the new valve in the same orientation as the old valve was mounted, with the gas inlet pipe facing toward the rear of the oven cavity and the two wire terminals facing upward toward the control area.
3. Align the two mounting holes on the valve with the two threaded holes in the oven burner box frame (located at the left rear corner of the oven cavity, approximately 4 inches from the left wall and 3 inches from the back wall).
4. Insert both 1/4-inch hex head mounting screws through the valve mounting flange and thread them into the burner box frame by hand, turning clockwise 3-4 full rotations to ensure proper threading.
5. Using a 1/4-inch nut driver or socket wrench, tighten the left mounting screw first, applying firm pressure until the screw is snug (approximately 15-20 inch-pounds of torque – stop when the screw no longer turns easily by hand but before forcing it).
6. Tighten the right mounting screw to the same tension, ensuring the valve sits flat against the mounting surface with no gaps visible between the valve flange and frame.
7. Locate the two spade terminal connectors you disconnected earlier – these will be attached to wires coming from the oven control area, typically one orange wire and one orange wire with a white tracer stripe.
8. Identify the two brass-colored terminals protruding from the top of the new valve body – these terminals are interchangeable, meaning either wire can connect to either terminal since the valve operates on a simple circuit without polarity.
9. Slide the first spade connector (orange wire) onto the left terminal, pushing firmly until the connector slides completely onto the terminal base – you should feel resistance as the connector grips the terminal.
10. Slide the second spade connector (orange wire with white stripe) onto the right terminal using the same firm pushing motion until fully seated.
11. Gently tug on each wire connector individually, pulling with approximately 2-3 pounds of force – the connector should remain firmly attached and not slide off the terminal.
12. Locate the gas supply line that you disconnected earlier and align the flare nut fitting with the threaded inlet on the rear of the new valve.
13. Thread the flare nut onto the valve inlet by hand, turning clockwise for 4-5 complete rotations until hand-tight – the nut should thread smoothly without resistance.
Troubleshooting Tips
**If spade connectors don’t fit tightly on terminals**: The connector opening may be too wide from repeated use – squeeze the metal sides of the connector slightly using needle-nose pliers to narrow the opening, then retry installation.
**If wire connectors pull off terminals easily**: The terminals may be too narrow or the connector too worn – replace the spade connectors by cutting the old ones off and crimping new 1/4-inch female spade connectors onto the wire ends using a wire crimping tool.
**If mounting screws won’t tighten**: Stop immediately and remove the screws – the threads may be stripped. Use a flashlight to inspect the threaded holes in the frame; you may need to use 10-24 thread size self-tapping screws instead of the original mounting hardware.
Step 7: Check for leaks
Check for Leaks
1. Turn the gas supply valve back on by rotating the valve handle counterclockwise until it aligns with the gas pipe (handle parallel to pipe indicates “open”).
2. Mix a leak detection solution in a small bowl by combining 1 tablespoon of dish soap with 1 cup of water. Stir until bubbles form.
3. Dip a small paintbrush or sponge into the soapy solution.
4. Apply the soapy solution to the gas connection at the safety valve inlet (where the gas line connects to the valve body on the left side of the oven burner assembly). Coat the entire threaded connection with a generous layer of solution.
5. Apply soapy solution to the gas connection at the oven burner orifice (where the safety valve outlet tube connects to the burner, located at the center-rear of the oven cavity). Cover all threaded areas and the base of the connection.
6. Apply solution to the main gas line connection at the back of the range where the flexible gas supply line connects to the range’s gas inlet pipe (accessible from the rear, approximately 12 inches from the bottom).
7. Watch each soaped connection for 30-60 seconds. Look specifically for bubbles forming or growing in size, which indicates escaping gas.
8. If bubbles appear at any connection, immediately turn off the gas supply valve by rotating it clockwise 90 degrees (handle perpendicular to pipe).
9. If leaks are detected at the safety valve connections, tighten the connection by turning the fitting clockwise with a 1/2-inch wrench. Apply one-quarter turn at a time, then retest with soapy solution.
10. If leaks persist after tightening, turn off gas, disconnect the leaking connection, inspect the threads for damage or debris, clean threads with a wire brush, reapply yellow Teflon tape (gas-rated) clockwise 3-4 wraps, reconnect, and retest.
11. Turn on one surface burner by rotating a burner control knob to “High” and pressing the igniter button. Listen for the clicking sound and verify the burner lights within 3-5 seconds.
12. Turn the oven control knob to 350°F and listen for the safety valve to open (you’ll hear a faint clicking sound followed by gas flow, approximately 5-10 seconds after turning the knob).
13. Verify the oven igniter glows bright orange-white and the oven burner lights within 90 seconds of setting the temperature.
14. Allow the oven to run for 5 minutes, then recheck all three gas connections with fresh soapy solution to verify no leaks develop under operating pressure.
15. Wipe away all soap residue from gas connections using a damp cloth to prevent corrosion.
**Troubleshooting This Step:** – If bubbles form rapidly, this indicates a major leak—shut off gas immediately and retighten or replace the connection – If the oven burner doesn’t light after valve replacement, verify the two wire connections at the safety valve terminals are secure by gently tugging each wire – If you smell gas but see no bubbles, the leak may be upstream—apply solution progressively backward along the gas line toward the main shutoff – Never use matches or lighters to check for leaks—always use soapy solution only
