Kenmore dryer overheats, causing the thermal cut-off to fail

After an initial cleaning of the exhaust between the dryer and the house, the dryer ran well and stopped heating all together. I troubleshot by following the steps below for "dryer won't heat" issues. Here are steps I took:

1) thoroughly cleaned the exhaust between the dryer and the outside
2) thoroughly cleaned the lint filter and blower area
3) replaced the thermal fuse, thermistor, thermal cut-off and high limit thermostat
4) tested the heating element w/Ohmeter. it reads right around 10 ohms, which I believe is ok

Now, I believe the dryer is overheating and causing the thermal custoff to fail. I replaced the thermal cutoff a second time and tested the dryer with it just venting into the room. Seems to work ok, but I am worried that if I put it back in service, it will overheat again.

Thank you for your question and I understand your concern. Thank you also for adding the model number to the thread.

Based on your symptom and details, the heater relay is likely sticking closed providing you do not have a venting restriction.

Based on you details the heater is Okay and not shorted to the heater housing. If the heater is shorted to the housing, it will cause the dryer to overheat. If the thermistor has the correct resistance readings and clean and tight connections then the most likely cause is the heater relay sticking closed.

The heater relay is located inside the console assembly. See images below.

To access the components,

disconnect the power cord

and then remove the left and right hand end cap covers and then remove the screw at the bottom of each end cap. Slide the control panel towards the front and lift it up and hinge it over the rear panel.

You will also see a motor relay too. You could swap the heater relay with the motor relay and see if it continues to blow the thermal cut off.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
