International Comfort Products N9MP1080F16A2 Defrost Sensor Board
The defrost control board initiates an important defrosting cycle in order to continue normal heating and cooling operations. The board looks to a temperature sensor located near the condenser to make the decision on when to initiate the defrosting cycle.
Major clues of a poorly working defrost sensor board
- The AC may not operate for the simple fact of the safety issue that the frost poses
- The main control board might issue a type of error code when encountering a problem
- Self defrost sequence refuses to run even though there is excessive frost built up
