check the relay for the damper and the fuse,these dampers can sieze with ice if not lubricated with grease on a regular basis.

theres a solid state controller inside the relay board box,
bolted up by the das, it'll be that

Linkage connecting motor to door often come adrift. Also motor has a heating element which energises below freezing. If this fails damper may not work at very low temps.
