✔️ Step-by-Step Repair Instructions
🔌
🔧 Step 1: Disconnect power
- Locate the dryer’s power cord at the back of the unit, positioned in the center bottom section approximately 8-10 inches from the floor.
- Grasp the dryer’s side panels and pull the unit forward away from the wall 24-36 inches to create working space behind it.
- Look at the wall outlet – this is a 240-volt, 4-prong outlet (NEMA 14-30R configuration) with four rectangular slots arranged in an L-shape.
- Grip the power cord plug firmly where the rubber molding meets the hard plastic plug body (not by pulling the cord itself).
- Pull the plug straight out from the wall outlet using steady, firm pressure. The plug will release after moving 1-2 inches outward.
- Visually confirm the plug is completely separated from the wall outlet – no prongs should remain inserted.
- Coil the power cord and drape it over the top back edge of the dryer to keep it off the floor and prevent tripping.
- Walk to your home’s electrical panel (circuit breaker box).
- Locate the double-pole 30-amp breaker labeled “Dryer” or “Electric Dryer” – this breaker will be twice the width of standard single breakers.
- Flip this breaker to the OFF position – the toggle switch will move from the center or right position to the left position.
- Place a piece of tape over the breaker and write “DRYER REPAIR – DO NOT TURN ON” on the tape using a permanent marker.
- Return to the dryer and verify the drum light does not illuminate when you open the door – this confirms power disconnection is successful.
- Press the dryer’s power button multiple times – the control panel display should remain completely dark with no lights, sounds, or responses.
🔧
🛠️ Step 2: Remove control panel
- Locate the two Phillips-head screws at the top of the control panel, positioned approximately 2 inches from each end of the panel width.
- Use a Phillips-head screwdriver #2 to remove both screws completely, rotating counterclockwise 8-10 full turns per screw.
- Set the screws aside in a container to prevent loss.
- Grip the control panel at both ends with your hands positioned at the outer edges.
- Pull the top of the control panel forward approximately 1-2 inches, tilting it away from the dryer body at a 30-degree angle.
- Lift the panel upward while maintaining the tilted angle until the bottom tabs (located at 3 inches from each end of the bottom edge) disengage from the slots in the dryer top.
- Rotate the control panel forward to rest it face-down on top of the dryer, allowing it to hang by the attached wire harnesses.
- Identify the main wire harness connector on the right side of the control board—a white rectangular plastic connector approximately 2 inches wide with 8-10 multi-colored wires.
- Press the locking tab on top of the white connector using your thumb while pulling the connector straight out from the control board socket with your other hand.
- Locate the door switch wire connector on the left side—a smaller white connector approximately 1 inch wide with 2-3 wires.

- Identify the ribbon cable—a flat, beige or gray cable approximately 1 inch wide with multiple thin copper traces visible through translucent insulation—connecting the user interface board to the main control board.
- Examine the connector at the user interface board end (top board), which sits in a white or black plastic socket positioned on the right side of the board, approximately 2 inches from the edge.
- Press down on the small plastic locking tabs located on each side of the connector using your thumb and index finger while pulling the ribbon cable straight out with your other hand.
- Inspect the ribbon cable for damage: look for any creases, tears, darkened burn marks, or areas where the copper traces appear broken or separated.
- Check the exposed copper contact strips at the cable end—there should be 8 to 12 individual metallic lines running across the width, each appearing bright and unoxidized.
- Examine both connector sockets on the boards for bent pins (tiny metal contacts inside the white plastic housing) or debris like lint or dust.
- Use compressed air to blow out both connector sockets, holding the can upright 3-4 inches away from the socket opening.
- Reinsert the ribbon cable into the user interface board socket by aligning the cable straight with the socket opening and pushing firmly until the locking tabs click into place on both sides.
- Repeat steps 4 through 9 for the opposite end of the ribbon cable where it connects to the main control board.
- Verify proper seating by attempting to gently pull the cable straight out—it should not release without pressing the locking tabs.
- Confirm the cable sits flat with no twists or sharp bends along its length between the two boards.
🔍
🔩 Step 4: Inspect UI board
- Locate the UI (User Interface) board, which is the circuit board mounted directly behind the control panel display at the top front of the dryer, measuring approximately 8 inches wide by 3 inches tall.
- Examine the board surface under good lighting, holding a flashlight at a 45-degree angle to highlight any surface abnormalities.
- Look for these specific failure indicators on the green circuit board:
- Inspect the 3 wire harness connectors on the board’s left side:
- Check the touchpad ribbon cable connector (flat, transparent cable entering the board’s right side) for proper seating—the cable should sit flush with no gaps visible between cable and connector housing.
- Examine all visible solder joints on the board’s back side by tilting the control panel forward—look for gray, dull, or cracked solder versus shiny, smooth dome-shaped joints.
- Test board functionality by pressing each button on the control panel while observing the LED display—all buttons should respond with corresponding display changes or beeps.
- If you found burn marks, bulging capacitors, or cracked solder joints, the board requires replacement (part number 137557600).
- If the board appears visually intact but buttons don’t respond, proceed to electrical testing in the next step.
