Carrier 50GX042300 Defrost Sensor Board
The defrost sensor board will begin the defrosting phase which helps to continue normal heating and cooling operations. The defrost board depends on a specific sensor that can be found near the condenser, in order to verify when the defrost cycle should begin.
What warnings should I watch out for to know if my defrost board is almost dead?
- Self defrost sequence never kicks in even though there is quite a bit frost in the way
- The HVAC system could not work for the simple fact of too much frost
- Your main control board could signify an error code if the defrost control board fails
