Recently I have replaced thermal cutoff twice. I have checked vent, heater every thing tests good. Why the thermal cut off is failing repeatedly? I read from question answers to check cycling switch, where it located and how do I test it?
ANSWER Hello Pyara,
The only thing that will open a thermal fuse is temperature. For this reason, I have to assume the exhaust duct is clogged or crimped. It has to have a full 4 inch diameter opening from the back of the dryer to the atmosphere, (outside of the home). If it is too long with too many turns, this will cause the issue also. There is a slight possibility of a drum seal leaking, but to blow the thermal fuse twice this quickly, the drum seal would practically have to be missing. This still points to the exhaust duct.
