Carrier 48GS042060300 Defrost Sensor Board
The defrost sensor board commences an important defrosting cycle which may be needed in order to keep the outdoor unit free from frost build-up. The board is relayed information from a defrost sensor which is near the condenser somewhere, in order to make the decision on when the defrost cycle should begin.
How do you know if your outdoor defrost sensor board is almost going bad?
- The main circuit board might give out a particular error code produced by a bad defrost control board
- Your system could end up not running due to the fact of the frost blocking the flow of air
- Defrost session never runs even when there is a large quantity of frost that has built up
