Whirlpool ATR0943SPP0 Thermistor
In an HVAC system, a thermistor is a special kind of new age resistor that has a fluctuating resistance that is governed by temperature. They inform the system when the temperature reaches a certain point. The system control board needs to know the temperature in several different areas to know what to do next.
What symptoms are present when the thermister is dying?
- The blower could possibly fail to begin to engage full speed
- The entire system may never begin due to any one broken thermistor
