Carrier 50TM004 Defrost Sensor Board
The defrost control board instructs the system to activate the defrosting phase which actually helps to keep your outdoor unit from plugging up. The board is influenced by a sensor located in the outdoor unit to determine when to begin.
Cues of an unhealthy AC defrost sensor board
- The main board might give out an error number when encountering a problem
- AC and heating system could stop functioning for the simple fact of frost blocking the fins on the outside unit
- Defrost mode has not run for quite some time even though there is quite a bit frost that makes the unit run like crap
