LG LP121HEM Defrost Sensor Board
The defrost control board controls when to launch the defrosting phase if necessary, to get rid of the frost that collects on the outdoor unit. The defrost sensor board depends on a defrost sensor which is near the condenser somewhere, in order to decide when the defrost cycle should begin.
Simple indications of a faulty defrost sensor board
- The primary control board might issue a particular error code produced by too much frost
- Defrost mode never initiates even though there is a lot of frost in the way
- Your system could stop functioning for the fact of frost blocking the fins on the outside unit
