Whirlpool ATE1555RPP0 Thermistor
In an HVAC system, a thermistor is a type of resistor whose rated resistance varies depending on the current temperature. They can tell the circuit board when the temperature reaches a certain point. The control board deciphers the temp in some specific areas of the system to make sure everything is running smoothly.
Major clues to watch for in a failing thermister
- The initial sequence could possibly never start depending on which is the bad thermistor
- Blower motor fails in the attempt to ramp up
