When I put the option heat my dryer over heats and shuts off what do you think is wrong?

Overheating is often the result of an air flow problem. Check the connections and make sure the dryer duct is clean and the outside vent. You need to go outside to check it.

If your air flow is good, the two most common problems would be a bad thermostat or a bad element.

On some of the newer dryers they have sensors that may be covered in lint and therefore are overheating. My dryer has a sensor behind the lint bucket and when it get's full of lint, it stops heating the clothes. Could also be a bad heat senor that is stuck in the open position.

These are small silver or black round disks with two ears with screws through them. They are most likely positioned near the heating element. They typically have two terminals with wires attached.

If you have access to a simple continuity tester you can check to see if these are bad by simply removing both wires and see if your buzzer goes off. Always touch the tips of your probes first before hand to verify you are getting a tone from your meter. If you get a tone it means the sensor is closed and working.

If there is no tone from your meter the sensor is in the stuck open position which does not let the heating element get hot. These are safety devices to protect you dryer from getting too hot and catching fire. Never bypass a safety device.Gh Temp sensors are rather inexpensive and can be replaced for a few dollars from your dryer dealer or appliance repair center.

Good luck and all the best ~~ dgicre.

Iit sounds like a thermostat, but i've been known to be wrong at times. Pray it is either the thermostat, or airflow as mr. steve oMc says. However I have a question besides the heating problem.

And that is how old is this dryer and is it gas or electrical?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
