International Comfort Products TCA230AKA1 Defrost Sensor Board
The defrost sensor control board initiates an important defrosting cycle which may be necessary to keep the outdoor unit free from frost build-up. The defrost sensor board relies on a specific sensor located in the outdoor unit to verify when the defrost cycle should begin.
Major indications of an inadequate AC defrost sensor board
- The primary control board could display an error code produced when the defrost control board fails to receive a signal
- Self defrost sequence does not begin especially when there is a rather large amount of frost in the way
- The whole system may cease to function due to the fact of way too much frost build-up
