Carrier 38YXA048 Defrost Sensor Board
The defrost sensor board instructs the outdoor unit to begin an important defrosting cycle which helps to continue normal heating and cooling operations. The board relies on a specific sensor which is near the condenser somewhere, in order to verify when to begin.
Major clues of a faulty defrost board
- The control board might give out an error number if the defrost board fails
- Most systems will stop running at all because of too much frost
- The defrost sequence has not run for a while despite the fact that there is a lot of frost built up
