International Comfort Products H8MPT075F14B1 Thermistor
In an HVAC system, a thermistor is a type of resistor that has a fluctuating resistance that varies depending on the heat. They inform the system when a temperature reaches a certain point. The control board reads the temperature in certain areas to make sure everything is running smoothly.
Simple signals your thermister will need replacing
- The blower fails in its attempt to ramp up to full speed
- The AC and heat system may not even start because of any broken thermistor
