International Comfort Products EF20N2600A2 Defrost Sensor Board
The defrost sensor control board instructs the system to activate the defrosting phase which assists to keep your outdoor unit from plugging up. It is influenced by a temperature sensor that can be found near the condenser, in order to determine when to begin.
Symptoms your outdoor defrost sensor board will not last the year
- Defrost mode has not run for quite some time especially when there is frost that makes the unit run like crap
- Air conditioning may cease to operate for the simple fact of the safety issue that the frost poses
- The control board could throw a particular error code produced by a failing defrost board
