Carrier 58MVP040 Defrost Sensor Board
The defrost control board will determine when to initiate the defrost cycle which may be needed in order to get rid of the frost that collects on the outdoor unit. The defrost sensor board looks to a defrost sensor located near the condenser to ascertain when to initiate the defrosting cycle.
What are some indications that my Carrier defrost sensor board is not working properly?
- The main board may show a type of error code if the defrost control board fails
- The whole system may stop running for the simple fact of the safety features installed
- Defrost mode will not kick in even though there is quite a bit frost in the way
