International Comfort Products T8MPV050B12B1 Defrost Sensor Board
The defrost sensor board controls when to launch an important defrosting cycle which may be needed in order to defrost your outdoor unit. The defrost board looks to a specific sensor which is near the condenser somewhere, in order to determine when the defrost cycle should begin.
Key signs of a faulty defrost sensor board
- The system may not run for the fact of frost blocking the fins on the outside unit
- The primary control board could display a type of error code when the defrost board fails
- Defrosting never kicks in even when there is a large quantity of frost built up
