The sensor relay is closed but the deicing system is not running. Why?

 

The heating system will be supplied by a different breaker that the one supplying power to the sensor. Make sure that this load breaker is closed.

Are you using a sensor load contactor? Confirm that this contactor is working properly.

Check to see if any included thermal overloads are not tripped.
