SPT WA-1420E Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrosting phase which actually helps to get rid of the frost that collects on the outdoor unit. The defrost sensor board depends on a temperature sensor located near the condenser to make the decision on when to initiate the defrosting cycle.
Clues to watch for to know your SPT defrost sensor board is in dire straights
- The control board may issue a particular error code when a defrost board fails to initialize
- The defrost feature will not kick in despite that there is a large amount frost that needs to be removed
- Air conditioning may stop functioning due to frost blocking the fins on the outside unit
