Have and older Whirlpool type 1 dryer that's overheating. The top gets red hot and it will shut off at the end of the cycle but it shouldn't get nearly THAT hot. Checked element for shorts by leaving the door open, set the timer on "Time setting" and checked the element - it's off. Pulled and checked the high temp thermostat by reading it closed across the terminals and using a stove igniter to heat up the bi-metal part till it opened (only about 20-30 seconds). That looks to be good too. Suspect a short in the temp switch because the element heats even when the switch is in the "air fluff" position. Am I on track here? I am concerned that the high temp t-stat didn't shut the element off when it got that hot but there's still the fact that the element is on when the temp switch is in "air fluff". Please Advise. Thanks. TTK

I think you may have a bias thermostat in you unit. It is just like a regular operating stat but generates a small amount of heat which causes the operating stat to open sooner keeping the drum cooler inside. I would check this. It is located on back side and looks much like others but is mounted on a little heater type plate. The wires are connected to the plate, not the stat.

Heat during air fluff is definately a problem.

What is the model number of the dryer so we can look up the wiring?

Thanks for the help!!

Esquire 1: I don't think I have one. I checked and didn't see anything like it. The temp selector has a copper thermocouple lead that goes down to, and mounts in, the ducting just prior to the exhaust vent. The only other component back there is the high temp stat.

I would change the temp switch as well as the high limit stat.then. Good Luck
