LG AMNH123APM0 Defrost Sensor Board
The defrost sensor control board is jobbed with determining when to begin the defrost cycle in order to keep your outdoor unit from plugging up. The defrost sensor board is relayed information from a sensor located somewhere by the condenser to make the decision on when the defrost cycle should begin.
Important hints the defrost sensor board will eventually need to be replaced
- Self defrost sequence has not run for quite some time even though there is a lot of frost on the unit
- The main board may throw a type of error code produced by a failing defrost board
- The AC may not work due to the fact of the frost blocking the flow of air
