This step-by-step dryer repair guide shows how to replace the electronic control board in an electric dryer.
You may need to replace the control board if the dryer won't power up even though you already checked the circuit breaker. You may also need to replace the electronic control board if the dryer powers up but won't start even though the door switch is working and the thermal fuse isn't blown.
Because the electronic control board manages all of the dryer's components and controls the dryer cycle times, it's difficult to pinpoint the control board as the source of a problem. Unless you see obvious damage to the control board or you've definitely determined that the control board failed, have a local dryer repair expert do advanced diagnostic tests before replacing the dryer control board with a manufacturer-approved dryer part.
Use this procedure to replace the electronic control board in many Kenmore, Frigidaire and Electrolux electric dryers. You also can use the same basic steps to replace the electronic control board in some Whirlpool, Maytag, Amana, Samsung, LG and GE dryers.
If you have a gas dryer, replace the electronic control board following this repair guide and video.
