Whirlpool ATR0743BPP0 Thermistor
In an HVAC system, a thermistor is a special kind of new age resistor which has a resistance that is solely dependent on heat. They can tell the main board when the temperature has been reached. The system deciphers the temp in certain areas to ensure that things are as they should be.
Simple signals the Whirlpool thermister will not live much longer
- The AC and heat system may not operate because of any thermistor that is stuck open
