I have a whirlpool duet dryer and it shows an E1 code, I have changed the thermistor and it is still doing it. I have cleaned it out. I have had to change the front timer circuit board, and the side circuit board, so what would the problem be now?
Wiring harness
I am assuming that you have the tech sheet.
I would also check your replacement thermistor with a meter.
Not unheard of to get a bad replacement part.
