Friedrich MW12Y3H Defrost Sensor Board
The defrost sensor board instructs the outdoor unit to begin the defrost cycle which actually helps to continue normal heating and cooling operations. The defrost sensor board depends on a temperature sensor which is near the condenser somewhere, in order to make the decision on when to initiate the defrosting cycle.
Hints your Friedrich defrost sensor board will need to be replaced
- Your system could end up not running because of the safety features installed
- Defrost mode never initiates despite that there is a large amount frost on the external unit
- The primary control board could throw an error code if the defrost control board fails
