International Comfort Products T9MPX060F12A2 Defrost Sensor Board
The defrost sensor board is jobbed with determining when to begin an important defrosting cycle which may be necessary to keep the outdoor unit free from frost build-up. The defrost sensor board depends on a defrost sensor that can be found near the condenser, in order to agree when the defrost cycle should begin.
Chief elements to watch for in a failing outdoor defrost sensor board
- The defrost feature has not run for a while despite the fact that there is a lot of frost on the external unit
- The primary control board may show a type of error code referring to a bad defrost board
- The system may not work for the fact of too much frost
