Whirlpool Dryer Not Heating

[TechnicianBrian]

Model Number: LER4634JQ0 , this dryer stopped heating and would only tumble the clothes. After removing the back and doing some quick voltage checks, I found the thermal cut-off had failed. Installed a new thermal cut-off and this dryer was up and drying again.

Hi,

I have the same model whirlpool dryer and same problem. (it tumbles but no heats)

But it has another symptom. Last time it was working, (still has heat) the dryer just won't stop. It runs for 2 hrs. My wife has to manually stop it by open the door. Since then, there is no heat coming out.

Any idea ?

Hi,

If you have a voltage meter it's a good idea to check the voltage to the dryer first.
You should have 220-240Vac.

If your voltage is ok you need to check the thermal cutoff just like TechnicianBrian talked about in this topic.

If the dryer will not turn off on a timed dry cycle you have a bad timer.

If the dryer would not turn off on a automatic cycle then you need to clean the lint out of the dryer blower housing and clean your dryer vent.

Cleaning the lint from the dryer blower housing and vent is something you should do either way as it's probably why the thermal cutoff went bad.

If you find the thermo cutoff is ok then take a look at the heating element.
