International Comfort Products HAC018AKA1 Defrost Sensor Board
The defrost sensor board determines when to initiate an important defrosting cycle which may be necessary to remove frost build-up that may accumulate. The control board is relayed information from a temperature sensor that can be found near the condenser, in order to agree when the defrost cycle should begin.
What are some indications that my defrost sensor board has a need to be replaced?
- AC and heating system could not operate due to the fact of the safety issue that the frost poses
- The HVAC system control board may throw an error code when a defrost board fails to initialize
- Unit defrost session has not run for quite some time despite the fact that there is a lot of frost that has built up
