✔️ Repair Steps
Step 1: Disconnect power
Disconnect Power
1. Locate the gas range’s power cord at the back of the unit – it exits the range approximately 8 inches from the bottom and 12 inches from the left side when viewing from the rear.
2. Pull the range away from the wall approximately 24-30 inches to create working space behind the unit. Grip the range on both sides of the cooktop surface and pull straight out, walking backward as you pull.
3. Look behind the range at floor level for the electrical outlet – it will be a standard 120V three-prong outlet (not the large 240V outlet used for electric ranges).
4. Identify the power cord plug – it has three prongs: one round ground prong (green/bare copper wire inside), one neutral blade (silver, connects to white wire inside), and one hot blade (brass colored, connects to black wire inside).
5. Grasp the plug body (not the cord) firmly with your hand and pull straight out from the wall outlet. The plug should release with moderate force – do not twist or rock it.
6. Examine the plug after removal – you should see three metal prongs intact and no burn marks or discoloration on the plastic housing. If you see damage, note this for potential replacement.
7. Locate your home’s circuit breaker panel and find the breaker labeled for the kitchen range or cooking appliances – it will be a single 15-amp or 20-amp breaker (not a double-pole breaker).
8. Flip the breaker to the OFF position by pushing the switch fully to the right until it clicks. The breaker handle should now be perpendicular to the panel or pointing away from the center bus bars.
9. Return to the range and verify power disconnection by attempting to turn on the oven control panel – press any button on the digital display. The display should remain completely dark with no lights, beeps, or responses.
10. Coil the unplugged power cord loosely and drape it over the top rear of the range to keep it elevated and out of your work area.
Troubleshooting Tips for This Step
**If the plug won’t pull out easily**: Check for a safety lock tab on the outlet – some outlets have a small plastic tab that must be pressed while pulling the plug. Apply pulling force straight outward, not at an angle.
**If the oven display still shows power after unplugging**: Your range may have a battery backup for the clock. This is normal – the battery only powers the clock display, not the spark module. Proceed with repair.
**If you cannot locate the circuit breaker**: Look for a breaker labeled “Kitchen,” “Range,” “Stove,” or “Cooking.” It will be a single-pole breaker (half the width of the main breaker). Test each kitchen breaker if labels are unclear.
**If the plug shows burn marks or melted plastic**: This indicates a previous electrical issue. Replace the plug and outlet after completing the spark module repair.
Step 2: Remove control panel
Remove Control Panel
1. Open the oven door fully to access the control panel mounting area from the top front of the range.
2. Locate the 4 Phillips-head screws securing the control panel. You’ll find 2 screws on the left side and 2 on the right side, positioned approximately 1 inch below the control panel’s bottom edge where it meets the main range body.
3. Using a Phillips #2 screwdriver, remove all 4 screws completely. Set these screws aside in a container—they are 1/4-inch diameter and you’ll need them for reassembly.
4. Tilt the control panel forward toward you at the top edge. Rotate it approximately 45 degrees, pivoting from the bottom mounting points. The panel will remain attached by wire harnesses at the back.
5. Support the control panel with your non-dominant hand while working on the wire connections. Let it rest at a 45-degree angle against your body or prop it gently against the open oven door.
6. Look behind the control panel. You’ll see 3 wire harness connectors: – **Main control harness** (largest, 12-pin white connector with multiple colored wires) – **Display connector** (smaller, 6-pin black connector) – **Spark module connector** (4-pin gray connector with 4 wires: red, black, white, and green)
7. Disconnect the main control harness first. Locate the white plastic locking tab on the connector. Press the tab down while pulling the connector straight out—it requires 3-5 pounds of pulling force. Do not twist or rock the connector.
8. Disconnect the display connector by squeezing the small release clips on both sides simultaneously while pulling straight back.
9. Disconnect the spark module connector (gray, 4-pin). Note the wire colors before disconnecting: – **Red wire** = Hot/power supply – **Black wire** = Secondary hot – **White wire** = Neutral – **Green wire** = Ground
10. Press the locking tab and pull straight out. This connector has a distinct click when it releases.
11. The control panel is now completely free. Set it face-down on a clean, soft surface (towel or cardboard) to protect the display and buttons.
Troubleshooting: If Wires Become Disconnected
**If individual wires pull out of connectors:** – Match wire colors to terminal positions on the connector housing – Red wires connect only to terminals marked with red or “L” (line) – Black wires connect to black or “L2” terminals – White wires connect to white or “N” (neutral) terminals – Green/yellow wires connect only to ground terminals (marked with ground symbol ⏚)
**Verification after reconnection:** – Each connector should click audibly when fully seated – Tug each connector with 2-3 pounds of force—it should not pull free – Wires should not show exposed copper at connection points
**Common mistakes:** – Forcing connectors in upside-down—look for alignment keys (small ridges) that only fit one way – Not fully seating connectors—push until you hear/feel the click – Pulling wires instead of connector bodies during disconnection, which can loosen individual wire terminals
Step 3: Disconnect spark module wires
Disconnect Spark Module Wires
1. Locate the spark module, which is a small black rectangular box (approximately 3 inches x 2 inches) mounted to the rear panel inside the range, 8-10 inches from the left side and about 4 inches down from the top edge.
2. Identify the wire harness connected to the spark module – you will see 6 individual wires plugged into the module: 5 white wires and 1 brown wire. The white wires connect to the igniters for each burner, while the brown wire is the ground connection.
3. Starting with the leftmost white wire, grasp the wire connector (not the wire itself) between your thumb and forefinger, approximately 1/4 inch from where it plugs into the module terminal.
4. Pull the connector straight back away from the module with steady pressure – it should release with approximately 2-3 pounds of force. Do not twist or rock the connector, as this can damage the terminal pins inside the module.
5. Repeat this process for the remaining 4 white wires, working from left to right across the module. Each white wire connector is identical and uses a friction-fit connection.
6. For the brown ground wire (located at the rightmost terminal), grip its spade connector and pull straight back. This connection may be tighter than the white wires and may require 4-5 pounds of pull force.
7. Once all wires are disconnected, examine each connector end – you should see a small metal terminal visible inside each white connector and a flat spade terminal on the brown wire. These should appear undamaged with no corrosion.
8. Bundle the 6 disconnected wires together and push them 6-8 inches to the right side of the range cavity to keep them out of your work area. The wires have approximately 12-14 inches of slack, so they will move easily.
Troubleshooting Tips for This Step
**If a wire terminal pulls out of its connector housing:** The white wires use push-in terminals. Look inside the connector housing for a small tab – push this tab down with a flathead screwdriver while reinserting the metal terminal until you hear it click into place.
**If you cannot identify which wire goes where during reassembly:** The 5 white wires are interchangeable – each connects to an igniter, and order does not matter. The brown ground wire ONLY connects to the rightmost terminal, which is larger than the others and may be marked with a ground symbol (three horizontal lines decreasing in length).
**If connectors are stuck:** The white connectors may have slight corrosion. Spray a small amount of electrical contact cleaner on the connection point, wait 30 seconds, then attempt removal again. Do not use excessive force, as terminals can bend at 8+ pounds of pressure.
**Verification after reconnection (for reassembly):** Gently tug each white wire with 1-2 pounds of force – none should pull free. The brown ground wire should also resist pulling with 2-3 pounds of force. If any wire pulls free easily, it is not fully seated and must be pushed in until you feel resistance.
Step 4: Remove mounting screws
Remove Mounting Screws
1. Locate the spark module/control board mounted on the left interior wall of the range cavity, approximately 8 inches from the top and 3 inches from the left edge – it’s a gray rectangular box measuring roughly 4×6 inches.
2. Identify the 4 Phillips-head mounting screws securing the module – two screws are positioned along the top edge (spaced 3 inches apart) and two along the bottom edge (also spaced 3 inches apart).
3. Check for wire bundles running across the screw locations – on this model, you’ll typically see a bundle of 6-8 wires (red, black, white, yellow, blue, and green) passing in front of the bottom-left screw.
4. Gently push this wire bundle downward toward the base of the range cavity, creating clearance of at least 2 inches above the screw head – the wires have sufficient slack for this movement.
5. Use a Phillips #2 screwdriver to loosen the top-left mounting screw by turning counterclockwise 8-10 full rotations until the screw is free – do not remove it completely yet, leave it threaded 2-3 turns in the hole.
6. Repeat this process for the top-right screw, loosening it but leaving it partially threaded to support the module weight.
7. Move to the bottom-right screw and remove it completely by turning counterclockwise, placing it immediately in your parts container – this screw is typically 1/4 inch shorter than the top screws.
8. Support the bottom of the module with your non-dominant hand, placing your palm flat against the base of the unit to prevent it from tilting or dropping.
9. Remove the bottom-left screw completely while maintaining support pressure on the module base.
10. Remove the top-right screw while continuing to support the module with your hand.
11. Remove the final top-left screw – the module is now free but still connected by wire harnesses, so maintain your supporting hand position.
12. Gently lower the module forward approximately 2-3 inches away from the mounting wall, allowing the wire harnesses to remain connected – the module should pivot slightly but not swing freely.
Troubleshooting Tips for This Step:
**If a screw won’t loosen:** Apply penetrating oil around the screw head, wait 5 minutes, then retry – these screws can corrode from heat exposure over time.
**If you drop a screw into the range cavity:** Use a telescoping magnetic pickup tool to retrieve it from the bottom pan – screws typically fall toward the front-left corner near the oven door hinge.
**If the wire bundle blocks screw access completely:** Temporarily disconnect the nearest wire connector (usually a white 6-pin connector located 4 inches below the module) by squeezing the locking tab and pulling straight out, giving you 6 additional inches of wire slack to move the bundle.
**If the module starts to fall when removing the final screw:** The unit weighs approximately 1.5 pounds – reinsert one top screw partially, then remove screws in the correct sequence (bottom-right, bottom-left, top-right, top-left).
Step 5: Install new module
Install New Spark Module
1. Remove the new spark module (part number DG94-00520A) from its packaging and place it on a clean, flat surface near the work area.
2. Inspect the new module’s mounting bracket – you’ll see two pre-drilled holes spaced 3.5 inches apart on the metal tab at the top of the module.
3. Hold the new module with the wire terminals facing downward and position it against the right rear interior wall where the old module was removed, approximately 8 inches from the top edge of the range cavity.
4. Align the two mounting holes on the module bracket with the two threaded holes in the metal chassis wall – the holes should match perfectly without forcing.
5. Insert the first Phillips-head screw (from your saved hardware) into the top mounting hole and hand-tighten it clockwise until the screw catches the threads – do not fully tighten yet.
6. Insert the second Phillips-head screw into the bottom mounting hole and hand-tighten it clockwise until both screws hold the module loosely in place.
7. Using your Phillips-head #2 screwdriver, tighten the top screw firmly in a clockwise direction for approximately 3-4 full rotations until the module bracket sits flush against the wall – the screw should feel snug but not over-torqued.
8. Tighten the bottom screw in the same manner until both screws are equally tight and the module does not shift when you press against it with light finger pressure.
9. Locate the white plastic wire harness connector you left hanging near the module location – it has 6 wire terminals visible inside the connector housing.
10. Examine the matching connector on the new spark module – you’ll see 6 metal pins arranged in the same configuration with a small plastic tab on the top edge of the connector.
11. Align the white wire harness connector with the module’s connector pins, ensuring the plastic tab on the harness faces upward to match the slot on the module connector.
12. Push the white harness connector straight onto the module’s pins using firm thumb pressure until you hear and feel a distinct click – this indicates the connector locking tab has engaged.
13. Verify the connection by gently pulling on the wire harness (not the individual wires) – the connector should remain firmly attached to the module without separating.
14. Position any loose wire bundles away from sharp metal edges by routing them along the right side wall, ensuring no wires rest on or near the gas valve assembly located 4 inches below the module.
Troubleshooting This Step
**If the mounting screws won’t thread in:** The holes may be misaligned – loosen both screws completely and reposition the module 1/8 inch higher or lower until the holes align naturally.
**If the wire harness won’t click into place:** Verify you’re pushing straight on (not at an angle) and that the plastic tab is oriented upward – rotate the connector 180 degrees if it still won’t seat properly.
**If you see bent pins on the module connector:** Use needle-nose pliers to carefully straighten each pin by gripping it at the base and bending it perpendicular to the connector face – bent pins will prevent proper connection and cause ignition failure.
**If the harness pulls out easily after connection:** The locking tab is not engaged – remove the connector completely, inspect for a broken tab on either connector half, and reconnect with additional firm pressure until you hear the click.
Step 6: Reconnect wires
Reconnect Wires to New Spark Module/Control Board
Wire Reconnection Sequence
1. Locate the main wire harness connector on the new spark module—it’s a white rectangular plastic connector approximately 2 inches wide, positioned on the right side of the module.
2. Identify the 6-wire harness connector you disconnected earlier. You’ll see these wires: one red wire, one white wire, one yellow wire, one blue wire, one orange wire, and one black wire.
3. Align the white harness connector with the matching socket on the spark module. The connector has a keyed shape that only fits one way—the wider tab on the connector faces toward the front of the range.
4. Push the connector firmly into the socket until you hear and feel a distinct click. The connector should be flush against the module housing with no gap visible.
5. Locate the individual spark electrode wires—these are 5 ceramic-insulated wires (typically gray or white ceramic coating) that connect to the top of the spark module at separate terminals labeled 1 through 5.
6. Match each electrode wire to its numbered terminal position on the spark module. The terminals are arranged in a row and clearly marked. Connect the wire from the left front burner to terminal 1, left rear to terminal 2, center to terminal 3, right rear to terminal 4, and right front to terminal 5.
7. Push each electrode wire connector straight down onto its terminal post until it snaps into place. You should feel resistance, then a click as the spring clip inside engages.
8. Verify each electrode connection by gently tugging upward on each wire with 2-3 pounds of pressure. The wire should not pull off. If a wire releases, push it back down more firmly until it clicks.
9. Connect the grounding wire—this is a bare copper or green-insulated wire attached to the spark module mounting bracket. If it came loose, reattach it to the green screw terminal on the module frame and tighten the screw clockwise 2-3 full turns using a Phillips-head #2 screwdriver.
Wire Connection Verification
10. Inspect each connection point visually. The harness connector should show no gaps, and electrode wires should be seated flush against their terminals with the ceramic insulation touching the terminal housing.
11. Check that no wires are pinched between the spark module and the mounting surface. Look along all four edges of the module for any trapped wires.
12. Verify the wire harness has 2-3 inches of slack and isn’t pulled tight. If wires are taut, gently reposition the harness to create slack.
Troubleshooting Wire Connections
**If the main harness connector won’t seat fully:** Rotate it 180 degrees—you may have it upside down. The keyed shape prevents backward installation, but the connector must be oriented correctly.
**If an electrode wire keeps popping off:** The spring clip may be damaged. Push down while rotating the connector slightly left and right to help the clip engage the terminal groove.
**If you’re unsure which electrode wire goes to which terminal:** The wires are the same length, so they’re interchangeable for testing purposes. However, for proper operation, trace each wire back to its burner location and connect according to the 1-5 sequence described in step 6.
**If any wire terminal appears corroded or loose:** Clean the terminal with fine-grit sandpaper (220-grit) and ensure the connector clicks firmly when reattached.
