Haier CPN10XC9 Defrost Sensor Board
The defrost control board instructs the system to activate an important defrosting cycle which may be needed in order to continue normal heating and cooling operations. The defrost board is influenced by a sensor located in the outdoor unit to verify when the defrost cycle should begin.
Key signs of a declining defrost board
- Defrosting never begins even though there is a lot of frost in the way
- Most systems will not work for the simple fact of way too much frost build-up
- The main circuit board might give out an error number when encountering a problem
