Goodman ARUF193116CA Defrost Sensor Board
The defrost sensor board controls when to launch the defrost cycle which helps to continue normal heating and cooling operations. The defrost board looks to a temperature sensor located near the condenser to decide when to begin.
Key signs of an ineffective defrost sensor board
- The control board may signify an error signal referring to the failed defrost sequence
- The defrost feature has not run for a while especially when there is frost that makes the unit run like crap
- The AC may stop operating due in part to the fact that there is too much frost
