Lennox OF25-120 Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin the defrosting phase which assists to continue normal heating and cooling operations. The board depends on a temperature sensor that can be found near the condenser, in order to agree when the defrost cycle should begin.
What signals that my defrost board is not working properly?
- The main circuit board may issue an error of some type produced by too much frost
- Defrost mode never initiates even though there is a lot of frost on the outdoor unit
- The system will stop running for the simple fact of too much frost
