99 HR Admiral Electrical Problems

I have a 99 Holiday Rambler Admiral 34F that has two problems I can't figure out, need some help. The first thing is the 110V wire for the refrigerator, its dead at the receptacle. Not sure which wire it is at the panel but when checking the breakers with a volt meter they are all on and putting out current to the wires screwed to it. Just wondering if anyone knows what path that wire takes to get between the panel and receptacle.
My second problem is the front A/C unit. When I turn the fan switch to auto it just makes a loud humming noise but if I turn it to on then the fan comes on and it will cool. Trying to figure out if this is the switch in the thermostat bad or something else. Any help on these problems would be appreciated.

Normally there are 2 outlets located behind the refrigerator. Supplies power via the inverter so you can run the refrigerator while boondocking. The 2nd on wired straight to the main panel and usually provides power to the icemaker. Depending on the inverter type you have it may have to be turned on to supply power.

The AC may have an issue with the start capacitor, this provides for additional voltage while starting. The capacitor may be bad. You may try switching the back to front capacitors to see if that solves the problem. You can also buy a Hard Start capacitor and add it to the circuit.

Hi I have the same year HR Admiral a 36G model I just checked my wiring chart and the frig plug is a GFI its on the same circuit as the bath that's the resettable GFI location on my coach and the kitchen outlets its tied to the 2A breaker you may have a bad connection up stream in the wiring line that feeds your frig plug I hope this helps
I contacted HR on their web site earlier this year with my coach serial number and chassis vin and they send the info to me on a pdf wiring for 12 and 110v charts and drawings with in a couple of days they even send the a copy of the window sticker

Thanks for the answer. I've got just the single receptacle for the frig that I can get to behind a plastic cover on the outside of the MH. Think that's a great idea to call the manufacture for a wiring diagram, will do it now and see what happens.

Turns out that it was the GFI in the bathroom all this time. Because of it not being set it killed the rest of the circuit. Reset it and now I have power to the fridge plug.
My next problem is the furnace. When I turn it on nothing happens, no clicks or sounds at all. Its a Atwood 8500-1V. I have read that the thermostat is supposed to send 12v to it to start the blower. I have a simple Thermostat made by dometic that is a analog type and it only has 7.5v on the hot post. It even has that marked on it so that must be right. What I don't understand is how can it send 12v to the furnace?
