Lennox 13HPD-042 Thermistor
In an HVAC system, a thermistor is a special kind of new age resistor whose rated resistance will fluctuate depending on the temperature. They inform the HVAC system when a temperature reaches a certain point. The HVAC system reads the temperature in several different areas to ensure that things are as they should be.
Red flags of a bad temp regulating thermister
- The main fan refuses to begin to engage full speed
- The heating and AC system could never start up due to any one thermistor that is malfunctioning
