Dryer is overheating despite replacing heating element & thermostats

My Maytag MEDC300XW0 dryer is hot. So, since I've torn it apart before and replaced stuff, I did the same a few days ago and found that the thermal cut off was not working and the heating element coils looked shot.

So, I ordered the parts and put them on today and turned it on. Heats up just fine but seems to be really hot at the top of the heat box ( too hot to touch after just a couple minutes). Just wondering if there is something I'm missing or that may be causing this problem.

The vent is blowing out hot air and the lint system has been thoroughly cleaned.

Same for me! I’ve replaced thermostat, high limit and the heat coils. Even in “Air Only” mode, the coils heat up? What else is left?!?

Pat, did you ever solve this issue? I’m having the same problem of the dryer calling for heat even in “air only.”

Your heating element is grounded! To check this use a multimeter to test for continuity by placing one probe on one of the terminals to the element, and place the other probe on the casing of the element. If there is continuity then your element is grounded and needs to be replaced.

Hi Pat,

Same problem here. Did you find a solution?

My best bet would be:

Cycling Thermostat

The cycling thermostat cycles the heat on and off to maintain the proper air temperature. If the thermostat is defective, it may keep the heat on too long, causing the dryer to get too hot. However, this is rarely the case. Before replacing the cycling thermostat check all the more commonly defective parts. If you have determined that all of the other components are working properly, test the thermostat by using a multimeter to test it for continuity. If the thermostat does not have continuity, replace it.

The above is right, Just make sure to look at the service manual/parts list to make sure their is no hidden thermostate.

If you checked the hot air just by removing hose connection from the machine's rear, make sure that you also check that exhaust pipe is clear all the way to the exit as a clogged exhaust will eventually cause an overheat on the machine's chamber. It is suggested to clean air vents at least once a year. Otherwise, I will go with the Cycling thermostat check as recommended by Mayer.

Replace the Timer ⏱️ if it has one or else replace heat relay or control board. Good luck 👍🏽

Do not just arbitrarily replace the timer! Check for continuity with multimeter.
