Bryant 379 Defrost Sensor Board
The defrost control board instructs the system to activate the defrosting phase which helps to defrost your outdoor unit. The control board depends on a defrost sensor located in the outdoor unit to decide when the defrost cycle should begin.
What are some indications that my defrost board is about to go out?
- The main circuit board may throw a particular error code referring to a bad defrost board
- The system may cease to function due to the frost issue
- Defrost session will not initiate even though there is a large amount of frost that makes the unit run like crap
