International Comfort Products CAC236AKA1 Defrost Sensor Board
The defrost control board will determine when to initiate the defrost sequence which may be needed in order to remove frost build-up that may accumulate. The defrost sensor board is influenced by a sensor that can be found near the condenser, in order to decide when to begin.
Some clues the defrost sensor board needs a replacement ASAP
- Self defrost sequence refuses to initiate especially when there is a rather large amount of frost on the external unit
- Air conditioning may not work for the fact of way too much frost build-up
- The main circuit board might give out an error code when encountering a problem
