Surburban sf30f furnace not working

[bmlentz17]

I need a little help with this furnace, I bought this 2005 keystone Springdale this summer and this is the first time I have attempted to use the furnance . When I attempted to turn it on via the thermostat. No power appeared to be reaching the furnace. Upon pulling it out and inspecting it I found that the wires were connected in a weird way that I had never seen, first the blue wires which normally run to the thermostat appear to be connected to a brown wire that runs up behind the fridge and disappears into the wall. The red batter wire was disconnected and so was the yellow natural wire. When I looked for a place to hook these sites up in hopes that I would get power, I observed 1 white/blue wire and one white with coming from under the fridge. I'm lost on how to fix this thing any suggestions

What colors are at the thermostat? It’s possible the previous owner switched wire colors to overcome a problem.

I pulled the thermostat and the brow wire is running to the thermostat so I'm assuming that solves the mysterious brown wire question...

I posted this in another thread but I think I may be able to get more help out of this one. I bought this 2005 keystone Springdale back in the summer and this is the first time that I’ve actually wanted to use the furnace. When I attempted to turn the furnace on earlier there was absolutely no power to the furnace everything from the duo therm thermostat worked in regards to the air-conditioning however there was no power to the furnace. I thought that maybe the last owner may have unhooked the furnace or turn the power off At the circuitboard and I needed to check the furnace anyway so I pulled it out and it’s wired in a weird way I’ve never seen. First I noticed a long brown wire which was connecting to the two blue wires which normally hooked up to the thermostat, however upon pulling the thermostat from the wall I noticed that the long brown wire was running from the thermostat to the furnace. I further notice that the red wire which usually is for 12 VOr battery was not hooked to anything in the yellow neutral wire was also not hooked to anything. As I looked further into the furnace compartment, I noticed that they were two white blue and white wires coming down from behind the fridge. Usually I’m used to seeing the wires from the furnace run up behind the fridge. So now I’m at a loss on what the issue might be can anybody help out? See the attached pictures

The furnace runs off of the DC system only as fare as the electrical section is concerned. You need to have a good battery and an ac source to maintain the battery via the converter.
