International Comfort Products T8MPL125J20B1 Defrost Sensor Board
The defrost control board is jobbed with determining when to begin an important defrosting cycle which helps to keep the outdoor unit free from frost build-up. It is influenced by a defrost sensor located near the condenser to decide when the defrost cycle should begin.
Major indications of a dying AC defrost sensor board
- Most systems will not operate because of way too much frost build-up
- The main control board might give out a specific error code produced by a bad defrost control board
- The defrost feature has not run for a while especially when there is a rather large amount of frost in the way
