LG ARUN115DT2 Defrost Sensor Board
The defrost control board is jobbed with determining when to begin the defrost sequence in order to get rid of the frost that collects on the outdoor unit. It is relayed information from a sensor which is near the condenser somewhere, in order to agree when the defrost cycle should begin.
How can I tell if my AC defrost sensor board is about to stop working?
- Defrost session never starts despite the fact that there is quite a bit frost built up
- Air conditioning may not work due to the safety features installed
- The HVAC system control board may issue an error of some type if the defrost board goes out
