Carrier 38EYG036 Defrost Sensor Board
The defrost sensor board determines when to initiate the defrost cycle which actually helps to get rid of the frost that collects on the outdoor unit. The board is influenced by a sensor which is near the condenser somewhere, in order to agree when to initiate the defrosting cycle.
Important hints your defrost board should be replaced
- The main circuit board may signify an error code produced when the defrost control board fails to receive a signal
- Your HVAC system will not run at all because of the amount of frost on the outdoor unit
- Self defrost sequence does not begin even though there is a large amount of frost in the way
