How do I replace an Electronic Control Board Gas in a Dryer?

Sometimes the door catch is attached to the door but other times it is attached to the front panel. The door strike is mounted across from it when the door is closed. The door can't be opened until it is manually opened. The catch should be replaced if the door doesn't close and the strike is intact. The door catch can hold the door closed to start the cycle but can't hold the door shut to keep the dryer running.

The back of the dryer has a terminal block with power cords connecting to it. If the power cord is overheated or shorted, the insulation will melt, if damaged wires don't complete the electrical circuit to the dryer, or if the outlet cord plug is disconnected.

The blower fan housing has a thermal fuse on it. If the air gets too hot, it will go to the outdoors. If the vent tube is blocked or the damper is closed, it will trip. The thermal fuse shuts off the dryer when it goes off. It prevents the dryer from heating, but the dryer still runs. If the dryer trips, the thermal fuse needs to be replaced.

The door latch assembly includes the dryer door strike. Sometimes it is attached to the front panel. The door strike is pushed into the door catch when it is closed. The door can't be opened until it is manually opened. If the door strikes something, replace it. The catch should be replaced if the door doesn't close and the strike is intact. If the door strike holds the door closed to start the cycle but can't keep the dryer running, replace it.

The drive motor shaft has a blower fan blade on it. The air moves through the dryer when the blower fan blade spins. The blower fan blade rattles or bangs if it's damaged. The blower fan blade should be replaced if it is broken.

The dryer door switch can be used to determine if the door is open or closed. If the door is open, the dryer won't start. If the door switch fails, the dryer will stop. If the switch reads that the door is open when it's not, replace it.

The front of the dryer drum has a plastic bearing. When the drum is rotating, the felt seal of the front panel allows the front of the drum to glide smoothly. The plastic bearing should be replaced if it is worn out or broken.

The operating thermostat senses the air temperature inside the dryer drum. It controls the heating element in an electric dryer and the burner in a gas dryer, turning that heat source on and off to keep the temperature in the Normal setting. If the thermostat doesn't work, the heat source won't be controlled and the dryer won't heat up. The operating thermostat should be replaced if it isn't regulating the dryer heat.

The small amount of friction needed for the belt to grip the drum is created by the idler pulley. It is a good idea to replace the idler pulley if it is damaged. It's not recommended to lubricate a motor pulley.

There is a motor relay in some dryers. The motor relay stays closed if the drive motor doesn't get the correct voltage from the electronic control board. When the voltage supply to the relay stops, the relay opens to stop the drive motor. When the start button is released, the dryer motor stops running.

Follow these steps to fix your issue:

  1. Shut off the power

    Shut off the gas when you unplug the dryer.

  2. Remove the top panel

    The dryer needs to be removed from the wall. There are two screws on the back of the dryer that secure the top panel. The 0.25-inch nut driver is required to remove the screws. Pull the top panel back to reveal the tabs. Take the top panel out of the dryer. The dryer cabinet should be vacuumed while you open it.

  3. Remove the electronic control board

    If you want to connect the new control board correctly, you need a picture of the wiring connections. Release the locking tabs with a slot screwdriver. Pull the wire harness plug from the electronic control board. The single head screw has a 0.25 nut driver. The control board needs to be released from the support slots. The control board should be set aside. The wire harness has enough slack to allow you to detach connections one at a time and immediately attach them to the control board, which is a sure way to get the connections right.

  4. Attach the new electronic control board

    Remove the control board from the package before touching the metal cabinet. The new control board needs to be pushed into the mounting slots. Attach it to the mounting hole by locking it into place. The mounting screw needs to be replaced. If you want to avoid overtightening, turn the screw with the nut driver until it stops, then give the screw one firm twist to snug it in. If you have a grounding strap, clip the lead to the cabinet before touching the new control board.

  5. Connect the wires

    Attach the wires to the electronic control board using your photo as a guide. The wire harness plug needs to be pushed until it snaps into place. Reorient the plugs if they aren't easy to fit together. Don't force the plugs in. Dryer components can be damaged if the wires are not connected correctly. A service technician can complete the repair if you are not sure about the connections.

  6. Reinstall the top panel

    Place the panel on the top of the dryer and away from the tabs behind the control panel. The tabs should be pushed forward by the panel. Remove the screws from the back of the dryer.

  7. Restore the power

    Go to the dryer and turn on the gas supply. The dryer can be plugged into the wall outlet.

  8. Shut off the power

    Plug the dryer in. Shut off the gas if it is a gas dryer.

  14. Install the new door switch

    Attach the door switch to the mounting screws.

  15. Connect the wire harness

    The new switch should be plugged into the wire harness. The locking tab needs to engage.

  16. Reassemble the dryer

    Put the top panel in place by lowering it. Attach the screws to the lint duct housing.

  17. Restore power to the dryer

    The dryer can be plugged into the wall outlet. If it is a gas dryer, turn on the gas supply.

  23. Install the new drum support roller

    The triangular washer is needed to secure the drum support roller onto the shaft.

  24. Reinstall the drum

    There is a support roller on the rear panel of the dryer cabinet. The drive motor and idler pulley can be accessed by lifting the front of the drum. Referred to the digital picture of the configuration, thread the drive belt through the idler pulley. To loop the drive belt over the motor pulley, push the idler pulley to the right.
