No heat from the dryer

First thing I did is go to PartsSelect to trouble shoot. Worked last time I had an appliance problem. It indicated that the thermistats are the most likely culprit since 82% of people claimed that to be the problem. I bought those two parts and that got me a little heat but it was still cutting off after a couple minutes...so, I bought the third part (Internal Bias Thermistor) and installed it later. Worked like a charm! Hasn't blown this hot in 5 years or more. While you're inside the unit, I also recommend cleaning out the blower and associated areas. They really accumulate lint and that cuts down the air flow considerably. I at least doubled the air flow as well as increasing the heat. Dryer is working like new!
