Lennox OF25-105 Defrost Sensor Board
The defrost sensor control board instructs the system to activate the defrosting phase which aids to keep your outdoor unit from plugging up. The defrost board looks to a defrost sensor located near the condenser to ascertain when the defrost cycle should begin.
How do you know when your outdoor defrost sensor board has to be replaced?
- The main board could display a type of error code referring to a failing defrost control board
- Self defrost sequence does not run even when there is a large quantity of frost that makes the unit run like crap
- The whole system may stop running due to the fact of frost blocking the airflow outside
