Update to what is going on:
Bought a fan motor, and little did I know, it was an entire kit complete with a capacitor. What's funny is that I went to this same RV place earlier in the day, and they said they didn't have my model's capacitor. If I would have known it came in the fan motor kit, I would have just gotten that.
So I setout to replace the fan motor on my Dometic. I think Satan himself must have designed this contraption! I started to take the squirrel cage off and I got to looking at it, and I didn't see any screws, bolts, nuts or anything. Then I looked and the cage that fits over the inner fan had these little metal tabs that you have to bend and the pop the whole thing off. It wasn't easy and took me over two hours to figure all of that out.
Once I got it off, I saw a major problem. The threaded studs that are on the opposing side of the squirrel cage where the actual fan motor bolts onto, all three of them had rusted and broken off when taking the nuts off. At this point, I started to seriously consider throwing in the towel and just getting a brand new unit. But then I considered all the time I had spent to this point, and I kept thinking, "what am I going to do about those broken studs?"
And then it hit me: JB's Steel Stick. I've used this on a transmission's dipstick tube that had a hole in it and it sealed that up good enough and hardened like steel, why not use it to mount this motor?
By this time, sun was almost down, I was drenched in sweat so I have called it a night. I did however work on the rest of the job, like pulling the fan motor wires through the protective sleeve and putting them into the little connector that it fits into in the ceiling and getting everything else ready. Supposed to be 100 plus in Texas tomorrow. Oy vey!
Edit: I forgot to mention that when taking the old motor off, I saw one of the wires to the motor had literally burned all the way through and was just hanging on by the plastic shroud around the wire. I thought of splicing it, but after all that work, I figured better to replace it.
