International Comfort Products CXA236AKA1 Thermistor
A very basic thermistor is a specific kind of resistor whose rated resistance is governed by current temperature. They tell the circuit board when a temperature has been reached. The furnace or AC reads the temperature in a few critical areas to make sure everything is running smoothly.
What are the indications that my main thermister is almost going bad?
- The heating and AC system could possibly not even begin because of the malfunctioning thermistor
- Blower motor could fail to begin to ramp up
