SPT WA-1220M Defrost Sensor Board
The defrost sensor board instructs the system to activate the defrost cycle which actually helps to keep your outdoor unit from plugging up. It is influenced by a sensor which is near the condenser somewhere, in order to decide when to initiate the defrosting cycle.
Indications of a deteriorating defrost board
- Defrost session never initiates despite that there is a large amount frost on the external unit
- Air conditioning may stop working for the fact of too much frost
- The main circuit board might issue a specific error code produced by a bad defrost control board
