LG AMNH093D4A0 Defrost Sensor Board
The defrost sensor control board initiates an important defrosting cycle if necessary, to keep the outdoor unit free from frost build-up. The defrost sensor board depends on a specific sensor located in the outdoor unit to agree when the defrost cycle should begin.
Major clues of a dying outdoor defrost sensor board
- The main control board may signify a specific error code referring to the failed defrost sequence
- The system will stop operating because of the frost blocking the flow of air
- Defrost mode has not run for a while despite the fact that there is a lot of frost on the unit
