Goodman ATUF182416 Defrost Sensor Board
The defrost sensor board is jobbed with determining when to begin the defrost cycle if necessary, to keep your outdoor unit from plugging up. The control board relies on a sensor located somewhere by the condenser to agree when the defrost cycle should begin.
Major clues your outdoor defrost sensor board will eventually need to be replaced
- The system may not run for the simple fact of the safety issue that the frost poses
- The defrost sequence will not kick in even though there is quite a bit frost that has built up
- The HVAC system control board may show a specific error code referring to a bad defrost board
