International Comfort Products T8MPN100F14A1 Defrost Sensor Board
The defrost control board instructs the system to activate the defrost cycle which may be needed in order to keep the outdoor unit free from frost build-up. It depends on a specific sensor that can be found near the condenser, in order to determine when the defrost cycle should begin.
Major warnings the defrost sensor board is in need of replacing
- The main control board might issue a specific error code referring to a failing defrost control board
- The defrost sequence never initiates despite the fact that there is a lot of frost on the external unit
- The system will stop functioning for the simple fact of the frost issue
