International Comfort Products C8MPL100J20B1 Defrost Sensor Board
The defrost sensor control board initiates the defrost sequence in order to keep your outdoor unit from plugging up. The defrost board is influenced by a specific sensor located near the condenser to agree when to initiate the defrosting cycle.
Subtle cues of a bad AC defrost sensor board
- The HVAC system could not operate for the simple fact of the safety issue that the frost poses
- The defrost feature has not run for quite some time despite the fact that there is a lot of frost on the unit
- The control board might give out an error number referring to a bad defrost board
