International Comfort Products T8MPT100J20A1 Defrost Sensor Board
The defrost control board initiates the defrost sequence which assists to keep the outdoor unit free from frost build-up. The defrost board looks to a defrost sensor that can be found near the condenser, in order to agree when to begin.
Indications of an ineffective AC defrost sensor board
- Defrost mode will not initiate despite that there is a large amount frost that needs to be removed
- Your main control board might issue an error signal if the defrost board goes out
- Your system could stop running at all because of the fact that there is too much frost
