LG AMNC123DEA0 Defrost Sensor Board
The defrost control board determines when or if to start the defrost cycle which actually helps to keep your outdoor unit from plugging up. It depends on a specific sensor which is near the condenser somewhere, in order to make the decision on when to begin.
Major symptoms of a deteriorating LG defrost sensor board
- Your system could stop working due to the fact of the amount of frost on the outdoor unit
- The defrost sequence never initiates even though there is quite a bit frost on the external unit
- The primary control board could throw an error signal referring to a failing defrost control board
