Haier HPRD12XC7 Defrost Sensor Board
The defrost sensor control board initiates an important defrosting cycle which may be needed in order to defrost your outdoor unit. The defrost sensor board relies on a sensor located near the condenser to decide when to begin.
Warnings your outdoor defrost sensor board is in dire need of a replacement
- Your system could stop working because of the frost issue
- The main circuit board could display an error of some type produced by a bad defrost control board
- The defrost sequence never starts even though there is excessive frost that makes the unit run like crap
