Does a bad thermistor cause the dryer not to heat?

Question: Does a bad thermistor cause the dryer not to heat?

My dryer keeps giving the f22 code but before that my dryer would not heat, can this be a bad heating element or this was it a bad thermistor causing the problem the entire time.

Hi Randy, The thermistor can certainly cause the dryer to not heat, but if it was not heating before it was giving the f22 code you may have multiple issues. There are a lot of different parts in the dryer's heating circuit that can cause it not to heat. The heating element, high limit thermostat, thermistor, control board, centrifugal switch on the motor. The parts in the heating circuit will just have to be tested with an ohm/volt meter to figure it out.
