International Comfort Products C8MPN100F20B1 Defrost Sensor Board
The defrost control board will begin the defrosting phase which may be necessary to keep your outdoor unit from plugging up. The defrost board is relayed information from a specific sensor which is near the condenser somewhere, in order to agree when to initiate the defrosting cycle.
Red flags of a poorly working defrost sensor board
- Defrost mode refuses to initiate even though there is a lot of frost on the unit
- AC and heating system could stop functioning because of the fact that there is too much frost
- The primary control board might issue an error code when the defrost board fails
