Spent two hours trouble shooting today. I was lucky to find out that behind the rear door pack & play door it is called is a hidden access area. Opened it up and I had access to the wiring. The thermostat definitely works. When it is supposed to kick in both blue wires have power. I also jumped them as it is obvious that they are going to the thermostat with no results.
I guess this means either the blower motor is dead or the control circuitry is dead right ?
The fan turns freely without any resistance. I will take the furnace out in Spring and continue to troubleshoot and buy whatever is required to fix it then.
The warranty ran out in June
Obviously I had a chance to but extended warranty from Suburban when I bought the trailer but I had no idea I could do that. So now it is between me and my wallet and the furnace
If there is anything else I should try, I am open to ideas .....
