Carrier 48XP030060300 Defrost Sensor Board
The defrost control board determines when to initiate the defrost cycle which actually helps to keep the outdoor unit free from frost build-up. The defrost sensor board looks to a temperature sensor located near the condenser to make the decision on when the defrost cycle should begin.
How can I tell if my defrost sensor board is almost going bad?
- Your main control board may signify a specific error code when the defrost control board refuses to initialize properly
- The system may cease to operate for the simple fact of the safety issue that the frost poses
- Defrost session never initiates despite the fact that there is a lot of frost that needs to be removed
