Payne PH1ZNA048000ABAA Defrost Sensor Board
The defrost sensor control board commences an important defrosting cycle which aids to get rid of the frost that collects on the outdoor unit. The board depends on a temperature sensor located somewhere by the condenser to determine when to initiate the defrosting cycle.
What red flags are there that my defrost board is about to go out?
- The main control board may throw a type of error code referring to a failing defrost control board
- Most systems will end up not running because of the frost issue
- Defrost mode refuses to initiate despite that there is a large amount frost on the outdoor unit
