Paragon W18 Defrost Sensor Board
The defrost sensor control board will begin an important defrosting cycle which may be necessary to keep your outdoor unit from plugging up. It depends on a defrost sensor located near the condenser to determine when to begin.
Hints of a poorly performing defrost board
- The main circuit board may show a type of error code produced by a failing defrost board
- Self defrost sequence never initiates despite the fact that there is quite a bit frost on the unit
- The system will not operate due to the amount of frost on the outdoor unit
