Blank Thermostat

[SJD]

Got up this morning and Airxcell thermostat blank. Has no display on it. It is the front thermostat on the 2017 Seneca that runs furnace. Therefore can not fun furnace. It was working fine last evening. The back thermostat works just fine but still can not turn furnace on with it. Any ideas??

The thermostat uses 12V power. Assuming both your thermostats use power from the same 12V source, then the source is not your issue. This could be a fuse - check all the fuses in the converter. Open up the thermostat itself as I seem to remember seeing a small little glass type fuse inside those? Maybe I'm wrong, but worth checking. Also look to see if all of the coloured wires coming out of the wall are attached securely to the terminals in the thermostat. If you have a multimeter, put that on the different wires/terminals in the thermostat to see if you get any voltage.

Found the issue. The furnace fuse in the fuse box was blown. It seems that the fuse holder was not perfectly inline. So when the factory put fuse in it was not in on one side and was just touching as a contact. Just a small quality check issue. Just have to know where to start looking to solve little issues like this.
