Nordyne MS3BA048KA Defrost Sensor Board
The defrost control board controls when to launch the defrost cycle which actually helps to remove frost build-up that may accumulate. The defrost sensor board depends on a sensor which is near the condenser somewhere, in order to determine when the defrost cycle should begin.
What are the clues to watch out for to know my defrost board is failing?
- The defrost feature has not run for a while despite that there is a large amount frost built up
- The main board might issue a type of error code referring to a bad defrost board
- The system will cease to function at all because of the safety issue that the frost poses
