Friedrich MW36C3F Defrost Sensor Board
The defrost sensor board initiates the defrost sequence in order to keep your outdoor unit from plugging up. The control board is relayed information from a specific sensor which is near the condenser somewhere, in order to determine when the defrost cycle should begin.
What are some hints that my defrost board is about to stop working?
- The defrost sequence will not initiate even though there is a lot of frost that needs to be removed
- The main board might issue an alphanumeric error code when the defrost control board refuses to initialize properly
- Your HVAC system will not run due in part to the safety features installed
