International Comfort Products T8MPT050B12B1 Defrost Sensor Board
The defrost control board is jobbed with determining when to begin the defrost cycle if necessary, to remove frost build-up that may accumulate. The defrost board relies on a defrost sensor which is near the condenser somewhere, in order to decide when the defrost cycle should begin.
Cues of a laboring defrost board
- Your main control board may throw a type of error code when a defrost board fails to initialize
- Defrost mode refuses to initiate even though there is quite a bit frost in the way
- The system will cease to function due in part to lack of airflow through the outdoor unit
