LG LP070HED Defrost Sensor Board
The defrost control board is jobbed with determining when to begin an important defrosting cycle in order to continue normal heating and cooling operations. The defrost sensor board depends on a temperature sensor which is near the condenser somewhere, in order to verify when to initiate the defrosting cycle.
What are some hints that my outdoor defrost sensor board is dying?
- Unit defrost session never begins even though there is a lot of frost on the external unit
- Air conditioning may stop operating due to frost blocking the fins on the outside unit
- The main circuit board may show a particular error code produced by too much frost
