International Comfort Products C9MPX100L20A2 Defrost Sensor Board
The defrost control board instructs the system to activate the defrost cycle if necessary, to continue normal heating and cooling operations. It relies on a temperature sensor that can be found near the condenser, in order to decide when the defrost cycle should begin.
Red flags the AC defrost sensor board should need replacing
- Your HVAC system will cease to operate due in part to too much frost
- The main control board may throw a type of error code produced by a bad defrost control board
- Defrost session never kicks in despite the fact that there is a lot of frost in the way
