Lennox XP14-042 Defrost Sensor Board

Major clues your Lennox defrost sensor board will need replacing
- Defrosting will not initiate even though there is a large amount of frost that needs to be removed
- The system will stop working due to the fact of the safety features installed
- Your main control board might issue an error signal produced by a bad defrost control board
