    Hi, my first time posting here so please bear with me. :) I have a 1992 Jamboree. Furnace has worked great for the last 2 years. The last few months there's been a periodic squeak, mostly when it starts up. Getting a bit worse. Have done some research and found I probably need a new motor. I don't think I have the right tools or comfort level to replace it myself but I might buy the motor then have someone else put it in. It's an Atwood Excalibur 8500-II type but not sure of the model. Do I need to find that on the motor or how can I find that? I've not opened it up from the outside yet. Thanks!

    You may be able to find some numbers on the motor to cross-reference. Most seem to have a big white tag on them. Looking at some Google images and YouTube videos, looks like when you take the access panel off outside the motor should be right at the front.

    Thanks Ray, I'll take a look there.

    I was hoping to be able to just oil the fan but sounds like its more like the bearings inside the motor rather than the fan itself, from what I've found by searching.

    At that age, my guess would be a worn motor. Usually, the bearings in those motors are sealed and not serviceable, once they dry out they probably start to squeak and fail. Seems like a common part in the range of 70-100 dollars, just need to make sure to get the right one.

    I've dealt with https://www.pplmotorhomes.com/rv-parts-rv-accessories in the past, they have a lot of these type of parts, was able to phone them up and get help with a replacement water heater. Price was good and shipping was quick.

    Thanks Ray, I did a search a bit ago for just the 8500-II and that site came up but realized I needed the model number. You were right - model number was right on the front of the motor. Am hoping it holds out a few more weeks when I'm in Sacramento area and having some other work done on the RV. Temps not too bad right now but heading toward Seattle in early April and am assuming more clouds and cooler. :)

    just thought I'd upload a photo to see how it works. :)

    hmm, this burned area on the wiring is a bit concerning...

    Looks like that crimp connection has likely oxidized and overheated a bit. Looks like there may be enough slack in the wire to just cut it back and add on a new crimp connector.

    oxidized? what causes that?
  • Ray

    It's corrosion like rust on iron or when silver tarnishes. Causes the electrical connection to gain resistance making for a poor connection and overheated joint. In this case, it could have been caused by moisture at some point or maybe the crimp has loosened over time.

    No problem :) :up: Let us know how the repair goes.

    As you can imagine I've put a lot of money into my RV. I'm pretty handy with a lot of things but not mechanical. So have to pay someone else to do all that. And its always something on a 1992 even though I think the Jamborees are great overall. But have been full timing 2 years and a lot replaced/fixed already so hoping it gets me through a few more years. :wink:

    I found this video that covers this repair. I understand your not wanting to tackle it yourself and it's always smart to defer if you aren't comfortable. The video may help though when you have it repaired to let the shop know you have some idea of what's involved. Often that can help from being overcharged.

    I went through this on an older RV. The screech is quite annoying.

    LOL thanks Greg, I think that was one of the videos I came across that convinced me I didn't want to try it. I maybe would if I had the right tools but don't think I do. I've done simple things like replaced my kitchen faucet and a (home type) toilet fill valve etc but since this is dealing with propane lines etc I'd prefer to let someone experienced tackle it. :nerd:

    Was it when he warned of getting shocked or when his hamster cage fan blew up? :yikes:

    :gasp: LOL no I didn't even get that far, he was using some kind of long narrow tool to get to one of the screws right off the bat and I knew I didn't have that so quit there.

    The Atwood manual for this model. I had to replace the motor in mine, constant squeal when cold. On some of the earlier models, the replacement motor is different from the original and takes quite a bit of modification to get it to fit.

    Thanks Roger, I'll take a look at that. I'm actually holding off it for the moment cause the squeak is not bad right now. I'm sure it will get worse but just hoping it will hold up for a bit longer. Have some other RV repairs that have priority.

    I know a guy who had a heating & cooling business who now works on RVs. He might be able to help, can't hurt to contact him and ask. @Eddie Aileen

    About 2 years ago the fan in my Suburban model SF25 furnace in my 2001 Komfort 5th wheel started squeaking. It took a few hours and was a PITA, but I took the furnace out and pulled the motor apart. The motor bearings were bronze. I cleaned the shaft with Emory paper, oiled the shaft and bearings with 30 weight motor oil and let it sit overnight. The next day I oiled it again and put it all back together. It hasn't squeaked since. But as they say, YMMV! (Your Mileage May Vary)
