It just happened overnight while in use. I woke up and was drinking my coffee when all of the sudden I was wondering what sounded like a very loud motorcycle was doing so close to my RV. I went outside and realized it the AC unit doing it's best imitation of a mean Harley. Definitely wasn't a good feeling! :) Luckily I have Amazon Prime though and the fan motor was relatively cheap on there. I got my replacement with free two day shipping and I was beating the heat again within just a few days.Re: A/C started making rough noises today. What should I check?Just wanted to chime and say thanks so much to everyone who helped me out in this thread. You guys saved me so much money and stress. The repair person I was speaking with estimated it would be $350 for the part plus labor. I got the motor for just $110 with tax and had it installed in about an hour. Both HVAC specialists I spoke to also advised me to just replace the entire AC unit rather than just the motor, and they both estimated it would be $1000+ including labor for a whole new unit. I am very grateful for everyone's input and I think I'll stick around the boards awhile! I really didn't expect such a wonderful community. Take care everyone and have a good weekend!Re: A/C started making rough noises today. What should I check?When splicing wires like this where should I cut them in terms of length? Close to the harness? I'm also wondering if I need to solder (which I've never done). I really hope the wire colors are the same! I don't know what I'd do if they aren't. Motor has been shipped though so I'm trying to get myself prepared. Thanks everyone.Re: A/C started making rough noises today. What should I check?Oops I realized part of the label isn't shown in that picture. I think I found the right replacement motor though. Looks like the original motor part number is 7184-0156 and on the Amazon reviews show that this is a viable replacement. I just want to make sure this is the right thing to replace and that I will be able to do it by myself. I've never done anything like this before but I'll take my time, just need a little guidance :). http://www.amazon.com/gp/product/B007VJUB9S?sa-no-redirect=1&pldnSite=1Re: A/C started making rough noises today. What should I check?The first picture is a closeup of the motor's label, there are some more pictures of the whole unit on the link below. I'm trying to get by without having to replace the whole unit. At this point it just seems like it's motor or bearings? I am not knowledgeable with this kind of stuff. Again, the shaft that's holding the fan is wobbling/vibrating so much that I cannot run the unit. There doesn't seem to be anything wrong with the fan itself. Thanks so much for the help. The make of the A/C I believe is a Coleman. My thermostat says Coleman-Mach on it. I'm in a 2001 Jayco Eagle fifth wheel.

What should I check?I was able to get up there today when the rain let up and it's not looking as easy as I suspected it might be. There are no nests are any obstructions. The noise seems to be coming from the vibration that the fan is giving off, although it doesn't seem lose in any parts. The rod that the fan is secured to that goes into the fan motor starts to wobble and the sounds gets louder the longer it's on. Is this an indication of a bad fan motor?Re: A/C started making rough noises today. What should I check?Thanks for the replies! I'll be working on it today whenever I can. Great timing for 3 days worth of storms in the forecast! :)A/C started making rough noises today. What should I check?It seems to be working fine but it's running very rough. I am currently in a very rural area and didn't plan on leaving for a week or two. Any ideas on what to check? It seems to be producing cool air but it sounds like a loud engine running or something along those lines.
