My whirlpool dryer is a Roper model. I am having problems with it shutting off in the middle of the cycle. It is like it is getting to hot, because if I put a small load in it at night when it is cool then it runs fine. Now the problem is that it is smoking. We have already cleaned all the lint out from the back and I always clean the lint trap at every load. What is the problem? Thanks Shantel

Reasons a unit runs too hot: 1) thermostat problem 2) poor air flow 3) blower motor not working
