The defrost sensor board commences the defrost sequence if necessary, to continue normal heating and cooling operations. It is relayed information from a temperature sensor located in the outdoor unit to make the decision on when to initiate the defrosting cycle.
Clues of an inadequate defrost board
- Defrost session will not kick in even though there is a lot of frost that has built up
- Your main control board might give out an error code produced by too much frost
- The whole system may stop working at all because of too much frost
