Samsung AVMWC070EA0 Defrost Sensor Board
The defrost sensor board is jobbed with determining when to begin the defrost cycle which may be necessary to keep your outdoor unit from plugging up. The board depends on a defrost sensor which is near the condenser somewhere, in order to ascertain when the defrost cycle should begin.
Signs of a poorly performing outdoor defrost sensor board
- The HVAC system could cease to operate due to way too much frost build-up
- Your main control board could display a type of error code produced when the defrost control board fails to receive a signal
- Defrost mode never runs despite the fact that there is quite a bit frost that makes the unit run like crap
