International Comfort Products 84 SERIES Defrost Sensor Board
The defrost sensor board determines when to initiate the defrosting phase which actually helps to defrost your outdoor unit. The board relies on a specific sensor located in the outdoor unit to make the decision on when to begin.
Warnings your outdoor defrost sensor board will soon need to be replaced
- The HVAC system could not work for the simple fact of frost blocking the fins on the outside unit
- The main board might give out an alphanumeric error code produced when the defrost control board fails to receive a signal
- The defrost feature refuses to run especially when there is frost in the way
