Mitsubishi PKA-A12HAL Thermistor
In an HVAC system, a thermistor is a certain type of resistor whose resistance is directly proportioned to current temperature. The control board must know the temp throughout the whole system to be sure everything is going well. They inform the system when a temperature has been reached.
Subtle cues of a defective temp regulating thermister
- The blower refuses in the attempt to engage full speed spinning
- The heating and cooling system could never start up depending on which is the thermistor that is the problematic one
