I have a Kenmore 110.97195120 gas dryer (electronic/propane). Lately, I've found it to overheat and shut down when in the permanent press setting (lowest heat/highest drying). I can set it on knit/delicate, and it seems to work fine. I opened the dryer up and cleaned the little bit of lint I could find, along with cleaning the vent pipe, and nothing seems to change. I have the Part No. 3395267 Rev. B Parts List. It appears a part will need to be replaced. Please help me identify what part to replace. Thank you.
