Questions & Answers

For Whirlpool Dryer High Limit Thermostat Kit (Part Number: OEM18143955)

1 Answer

Douglas, You will want to test the hi limit to make sure that it has continuity. It would also be recommended to test the gas coils to make sure that they are good and check the operating thermostat to make sure that it is not defective.

Dave, You will want to check the venting of the unit to make sure that the venting is clear. If this is ok then the most likely cause would be weak gas coils on the unit.

Jimmy for Model Number Maytag MGDC400VWO

I have a Maytag gas dryer that is about 6 years old, A couple nights ago, my wife put some clothes in the dryer and the dryer ran for a couple hours before she realized that it was still running. She checked and the clothes were dry. She started another load, and the dryer will not heat. I'm thinking that most likely this is the cycling thermostat? Would the cycling thermostat keep it from shutting off? I did replace the valve coils a little over a year ago.

1 Answer

Jimmy, With the unit not shutting off by itself then this would be more likely a timer issue. It could be a cycling thermostat if the timer is not advancing and you could check the thermostat for continuity to make sure that it is good.

Andrew T for Model Number 110.74652400

hello, I have a kenmore dryer model # 110.74652400. I have a problem with it not heating up. At first it heats up. The igniter glows and ingites the flame. after a 1 or 2 flame will go out. and reignites again when igniter glows. But after awhile it just stops igniting the flame. the igniter will glow but will not ignite a flame. I have tested all parts with a multi meter and came back good. only 2 part i could not fully check was high limit thermostat and cycling thermostat. Thay had to be at high heat to test them. So I am not sure if it is them or maybe possibly the gas valve itself. Thank you for your time.

Andrew, You described the classic gas valve coil failure. After a few cycles the magnetic coil will "breakdown" and will not raise the internal plunger to allow the gas to flow through the valve body. Replace the gas valve coil kit 279834 / 694540 and you should be fine. By the way, all the thermostats should have a "closed" circuit at room temperature. The coil kit is in stock and available at this time. Thanks,

Andrew, It would be possible that the cycling thermostat would be the cause of the unit no igniting but would be more likely the gas valve since the igniter is igniting.

Hello Ed. You will need to check and see if the cycling thermostat is bad and will need to be replaced on the unit.

Patrick, Check the broken belt switch to make sure that it is good and is depressed. If this checks ok then the motor would be the issue with the unit not starting.

Hello Ray. You will need to check the cycling thermostat and all the wiring on the unit. Also, make sure your house breaker is good.
