|Dometic Duo-therm makes click when trying to turn furnace on at thermostat||Teri||5-21-17|
|Our Dometic Duo-therm makes a click when you turn on the furnace and move the temp on thermostat. Furnace never turns on. Hasn't worked since taking out of winter storage. AC seems to work fine.|

|The control box in the AC has a relay that runs the furnace, That's the click you hear.|
As the 12 volt power to run the AC control box comes from the furnace we can guess that the furnace is getting activated.
We need to check inside the furnace for trouble. You didn't tell me what furnace you have so I am at a loss from there to advise you.
