Maytag Neptune heating issue
Model Number: MDE9700AYW Brand:
5 - 10 years
Dryer all of the sudden will not dry clothes. After troubleshooting the sensors, I checked for diagnostic codes and found an 02 code for the thermistor "opened sensed". Checking the resistance I found it to be 11k ohms, which was one of the possible issues. Vent pipe is not clogged and ambient outside temp was in the 70's. I also noticed when you would turn the dryer on it would seem to heat up for a few seconds then turn off. I replaced the thermistor and there is no change and the 02 code is still active even after clearing and it will heat for a few seconds and turn off. Ideas would be greatly appreciated.
Update: I checked the new thermistor and it read 9k+ ohms. I have noticed that the heater relay will kick on when first starting up and then kick off seconds later. Assuming this is from the thermistor code and assuming the thermistor is good. Could I use a 10k resistor in place of the thermistor to confirm that the control board is bad?
