LG LMAN120CNS Defrost Sensor Board
The defrost sensor board instructs the outdoor unit to begin the defrost sequence if necessary, to get rid of the frost that collects on the outdoor unit. The board relies on a specific sensor that can be found near the condenser, in order to determine when the defrost cycle should begin.
Key clues of a failing LG defrost sensor board
- The main control board may issue a specific error code when the defrost control board refuses to initialize properly
- Self defrost sequence has not run for a while even though there is a lot of frost on the unit
- The system may cease to function due to the fact of frost blocking the fins on the outside unit
