Haier CPN12XC9-E Defrost Sensor Board
The defrost control board initiates the defrost cycle which actually helps to keep the outdoor unit free from frost build-up. It relies on a defrost sensor that can be found near the condenser, in order to determine when the defrost cycle should begin.
General indicators that your your defrost board will eventually need to be replaced
- The whole system may not run due to the fact of frost blocking the airflow outside
- Self defrost sequence has not run for quite some time especially when there is frost that needs to be removed
- The primary control board may show an error number produced by a bad defrost control board
