LG AMNC093D4A0 Defrost Sensor Board
The defrost sensor board is jobbed with determining when to begin the defrosting phase in order to get rid of the frost that collects on the outdoor unit. The control board is influenced by a temperature sensor which is near the condenser somewhere, in order to ascertain when the defrost cycle should begin.
Important hints the AC defrost sensor board needs a replacement ASAP
- The primary control board may issue an error code produced when the defrost control board fails to receive a signal
- Defrost mode never starts even when there is a large quantity of frost on the outdoor unit
- The AC may stop functioning for the simple fact of the amount of frost on the outdoor unit
