Whirlpool ATR0945SPP0 Thermistor
In an HVAC system, a thermistor is a certain type of resistor whose rated resistance varies depending on the heat. They inform the system when the temperature reaches a certain point. The furnace or AC reads the temperature in some specific areas of the system to be sure everything is going well.
How can I tell if my main thermister has a need to be replaced?
- Primary blower may refuse to begin to begin full speed blowing
- No component may not even start because of any thermistor that is stuck open
