I apologize in advance for being a light on the model numbers( im not in need of assistance at this point) But I was just curious if anyone has come across an outdoor thermostat used with a dual fuel kit and found that switch contacts were stuck open (because of cold weather). I checked the continuity for the switch and had nothing then after exercising the dial on the outdoor stat the furnace began to work properly. So the unit is working fine now I was just wondering if anyone else came across the same solution. And by cold weather I mean it has been 5-20 degrees the whole last week.
