Friedrich VHA12K Defrost Sensor Board
The defrost sensor control board controls when to launch the defrost cycle which aids to keep your outdoor unit from plugging up. The board depends on a defrost sensor which is near the condenser somewhere, in order to verify when to begin.
Subtle hints the defrost sensor board has very little life left
- Defrost session has not run for a while especially when there is a rather large amount of frost that needs to be removed
- Your system could not run due to the fact of frost blocking the fins on the outside unit
- The main circuit board may show an error signal when a defrost board fails to initialize
