When you have your AC out for repair be sure to install the HARD START KIT on it if it doesnt allready have it.

When I had mine repaired at a certified RVP repair center it was installed as a matter of course on all he works on, I believe the parts cost was $19.80

Your compressors will spool up easier. Heavy duty capacitors I believe and not exactly sure what the difference in what they would look like.
I bet a few knowledgable friends here will fill in the blanks

The squirrel cage definitely sounds like your problem. When you get the top off the unit you still may have trouble verifying that the cage is the issue. All the blades are fastened to the "hub" with bent tabs and are not "welded" in place. They just loosen over time and even though you may not be able to fell them they can cause the tinny "rattle" sound you describe when under centrifugal force.
The bearings Duner provided a part number for were not available to me so here's what I used........ Grainger the brass bushing is $10.32 ( Dayton 2X567). The sealed ball bearing equivalent is $14.41 (Dayton 2X897) Hope this helps you.

I should have directly mentioned that mine sounds different in heat mode vs. AC. And that the heat mode makes more sounds. But only when starting up. After that it sounds OK.

Thanks guys.
You guys are way cool. You're making me want to venture out and get the tool box in place, the music on, scalpel, forceps, and... Oh, wrong process. Anyway, it sounds like you've got me covered in the possible issues with this beast. I almost can't wait to dive into it. It's a nice day here so, it just might happen. Thanks again. Very much appreciated.

Kix is right on the mark about changing the squirrel cage...After a visual inspection of mine I decided to change the bearing in an attempt to silence the "rattle" coming from my unit...Did not help!!!....Removed the squirrel cage the second time I had the unit out and replaced it with a new plastic model...Problem solved!!!...Found out once the metal sqirrel cage was removed that the center bronze bushing they used for the fan hub was pressed on and had worked loose...At operating speed it actually wobbled creating the noise.

Fire Up,
Mine is acting just like yours so I guess the next step is to pull the cool thing. It's a little cold here but the sun is out, may take a couple of days but hey, what the heck.

I have not found any treads for pulling the unit from the 07 Journey (diesel) 36 G and I beleive you also have a diesel so maybe we can compare notes. There is not a side door and I don't know how the side panel is attached to the coach.

Looking under the coach I see approximately 7 to 8 ea 5/8 or 11/16 bolts holding the mounting bracket (they may also be 15 mm bolts). Air duct in back near rear. I read about using motocycle jack to grab and lower unit so I will position it first. I'm not sure if condenser comes out with unit and it is large so with unit on jack I don't think it will fit between lower body and drive way. I have also not located the power conectors.

Any issues you run into let me know and we will compare notes.

thanks

I don't have the same coach but I think they are mostly installed the same way
There is not a side door and I don't know how the side panel is attached to the coach.
The side panel is hinged at the top just like the other basement doors. There are a couple of screws on the bottom and perhaps a couple that can be taken out from an adjoining basement door opening

Looking under the coach I see approximately 7 to 8 ea 5/8 or 11/16 bolts holding the mounting bracket (they may also be 15 mm bolts). The A/C on my coach is "locked" into place by the underneath bracket pressing upwards. The upward motion is provided by two bolts (3/4" wrench) on the outer front and rear corners.
Air duct in back near rear. Lots of screws fasten the air duct to the A/C. All must be removed.
I read about using motocycle jack to grab and lower unit so I will position it first. I'm not sure if condenser comes out with unit It's a package unit. It all comes out together.and it is large so with unit on jack I don't think it will fit between lower body and drive way. I have also not located the power conectors. Power does not need to be disconnected......the cables are long enoug to get it outside the coach. Also, it can be run "on the bench".

Hope all this helps you guys.

jk,
Well Sir, I certainly will let you know what I find. I don't know if you've seen dunner's great write up and picture display of the removal of the A/C unit or not but it's absolutely great. Although the one he works on removes from the side, it appears that maybe yours and mine come out through the bottom. I also don't know if you've seen all my posts or not on this subject but, the last time I went in to check it out by running the heater, it was all but incredibly quiet from the inside, not like it was when we were at Quartzsite for a week. But, when I went to the outside to listen, I could hear the slight "clanging-banging" of what could be maybe the squirl cage fan might be having issues. It's not overly loud though. You have to get right down next to the grill to hear it and it's a quiet neighborhood. So, at this time, I'm 50/50 on tearing it out or not. I most likely will tear it out just to get the job done and, maybe take a look at the motor bearings and if not anything else, lube them through the little doors. We'll see.

Kix,
Thanks for the alternate answers here. The more I read, the more I'm armed with knowledge of what to look for and do when this unit is removed. Very much appreciated.

I just changed my bearings last week in my o2 Journey 32T. The only difference from Dunner's removal is that mine had a U channel bar under the unit toward the outside. This bar will drop down after loosening the 2 1/2" or 5/8" bolts at each end. Loosen those 2 bolts about 1 inch and the unit will drop down enough to slide it out the side.

If you have any questions you can PM me but I willl be gone all day today (Tuesday)
