Carrier P4 Defrost Sensor Board
The defrost control board will determine when to initiate the defrost cycle which aids to continue normal heating and cooling operations. The board is relayed information from a sensor that can be found near the condenser, in order to decide when to begin.
What warnings should I watch out for to know if my AC defrost sensor board is about to stop working?
- The system may not operate at all because of the amount of frost on the outdoor unit
- The main circuit board could throw an alphanumeric error code produced by too much frost
- The defrost feature has not run for a while despite the fact that there is quite a bit frost built up
