Carrier 50JZ Defrost Sensor Board
The defrost control board commences the defrost cycle which aids to keep the outdoor unit free from frost build-up. It is influenced by a specific sensor located in the outdoor unit to determine when to initiate the defrosting cycle.
What are some indications that my defrost board really needs to be replaced?
- Unit defrost session will not kick in even though there is a large amount of frost that makes the unit run like crap
- The whole system may end up not running at all because of the amount of frost on the outdoor unit
- The main circuit board could signify an alphanumeric error code when the defrost board fails
