Nordyne MS3BC042KA Defrost Sensor Board
The defrost sensor board commences the defrosting phase which may be needed in order to get rid of the frost that collects on the outdoor unit. The defrost board depends on a defrost sensor which is near the condenser somewhere, in order to verify when to begin.
How can I tell if my defrost board is about to go out?
- The main control board may show a type of error code if the defrost control board fails
- Self defrost sequence has not run for a while even though there is a lot of frost on the outdoor unit
- The system may stop operating due to the fact of the amount of frost on the outdoor unit
