Just got back from a 4 day stay in my 2006 Montana 3400. My Montana is permanently set up on an RV lot that I own. The last time I was there 30 days ago the AC and furnace worked perfect. This trip the thermostat is acting funny and I can't get anything to work. I searched Youtube and found a guy with the exact same symptoms. Here is his video. Unfortunately, he thru a bunch of money at the problem and doesn't quite know what really fixed the problem. I wondered if anyone else had ever seen anything like this? I did a reset on the thermostat and now only get an EE code.
One thing I did do before I tried the heat/ac was swap out the 12 volt battery. The one in there now could possibly be dead. I am plugged into 30 amp AC at all times there.
