Whirlpool ATR1252BPP0 Thermistor
In an HVAC system, a thermistor is a type of resistor whose rated resistance is directly proportioned to temperature at its location. They convey to the HVAC system when a certain temperature has been reached. The system control board reads the temperature throughout the whole system to be sure everything is going well.
Simple signals the temp-regulating thermister is failing
- Blower fan fails to begin to engage full speed spinning
- The initial sequence may not function due to a inaccurate thermistor
