LG LMN120HE Defrost Sensor Board
The defrost control board will determine when to initiate the defrost cycle which aids to get rid of the frost that collects on the outdoor unit. It is influenced by a temperature sensor which is near the condenser somewhere, in order to determine when the defrost cycle should begin.
Important clues of a poorly working defrost board
- Defrost mode will not kick in even though there is quite a bit frost built up
- The HVAC system control board could display a specific error code referring to a failing defrost control board
- Your system could stop working due in part to way too much frost build-up
