Carrier 50XZ036300 Defrost Sensor Board
The defrost sensor control board controls when to launch the defrost cycle which may be necessary to continue normal heating and cooling operations. The control board looks to a sensor located in the outdoor unit to decide when to initiate the defrosting cycle.
What are the clues to watch out for to know my defrost board is about to stop working?
- The control board may issue a type of error code referring to the failed defrost sequence
- The HVAC system could stop operating for the fact of way too much frost build-up
- Self defrost sequence never runs even though there is a large amount of frost that has built up
