Hey jjrbus! Not knowing the first thing about capacitors, a few additional questions. The existing capacitor is "flattish", the Amazon one you recommend round. I'm sure this is a non factor, but please confirm its ok. Plenty of room, btw, it'll fit. If the Amazon recommended capacitor is not a perfect match, can I harm the system? And the most important thing - the wire connections, and where they go. I imagine they must match exactly (the red wire goes in the red wire spot, the yellow wire goes in the yellow wire spot, etc. I took a crappy picture of my capacitor with a little more info, may provide matching information, attached. Thank You!

OK, removed AC shroud and went inspecting. The electrical fan is directly connected to the bladed end in front, and connected the squirrel cage fan in back. When I turned the bladed fan by hand, the squirrel cage fan turned along with it. I originally thought the squirrel cage fan was underneath driven by a cable. Wrong. What I was hearing while in the cabin, when I turned the ac on, was the compressor kick in (which it still does) I'd reported that the bladed front end started when turned on. Nope. Neither the Bladed front spin, nor the squirrel cage fan spin when turned on with the inside control panel because, as it turns out, the electrical motor does not start. I removed the the lid to the box containing the capacitor (last photo). Looks like the original. So, It's either the capacitor, or a moribund electrical motor. As previously reported, when I manually spin the squirrel cage fan, the electrical motor does start. It spins the fans, and the AC kicks in and blows strong cold air. I guess I'll start with replacing the capacitor, unless somebody weighs in other wise. All input appreciated! Thanks for looking and for all your help everyone! (last two pictures uploaded sideways, sorry. When I flipped them correctly, upload would crop them). WME, I concur, I think it's a 2 in 1. EDIT: I found an identical capacitor on ebay for $6 (described as working when pulled), so this may be step one.

Good questions. It' hard to tell about the squirrel cage fan being tight or not. When I spin it, it rolls plenty smooth. The following has occurred to me. The big electric motor on top, the one under the shroud that propels the bladed fan (which starts/works), sits right on top of the squirrel cage fan, which is part of the inside control panel and directly below it. I wonder if there is a pulley behind the electric motor, and if there is a belt that connects from the pulley to the squirrel cage fan. And if that's slipping. I need to take the shroud off again. The back of the electric motor is covered in a sheet metal box, which if I remove, may expose the problem.

I'll take pictures of the un-shrouded unit today and post. When both fans are blowing (remember, the bladed fan on top does start on its own, and I manually spin the barrel fan to get it started), and the AC set on high, it blows plenty cold. It's not the compressor. It's just the barrel fan (upper right box in photo), the one I can see when I remove the housing on the inside of the cabin, that won't engage on it's own. Maybe they're both on the same motor, but that wasn't visually apparent when I removed the shroud cover on top. That bladed fan went directly into an electric motor. I can not see what's driving the barrel fan.

I removed the shroud, re-connected elect., turned the AC on and the the top fan came on, but the bottom one remained off. There are two fans, one that looks like a common bladed fan, located under the shroud, and a barrel type fan, located closer to the interior of the cabin. They do not operate on the same motor) Anyway, my manual spin trick got the whole system going so there's something wrong alright. Thinking of replacing the start capacitor with the one recommended by WME . I can do electrical, but if someone could please confirm that said part, the Coleman RV A/C HARD START KIT DIY no wiring easy CLIP ON (look at the above link) will indeed work on my 1989 Micro Spirit AC unit, I'd appreciate it. It was dirty under the shroud Linda, (mud dauber nest, dirt, leaves), but looked ok otherwise. ALSO, does the start capacitor replacement recommended here works in conjunction (or over rides, not entirely sure) the existing faulty start capacitor. Can I just not replace the faulty capacitor? Take the old one out, put the new one in? Is the reasoning behind the "Coleman RV A/C HARD START KIT DIY no wiring easy CLIP ON" because it's easier to get up and running? Because it's less expensive than the existing replacement part? Online, some folks think the Coleman RV A/C HARD START KIT DIY no wiring easy CLIP ON (and other similar brands) is temporary, not quite a best practice solution/fix. Please let me know your recommendations and opinions, I really appreciate them Thanks everyone!

With the AC/fan in the ON position, I could see that the fan would not engage/spin. I turned the AC off, reached in there and gave the fan a hearty spin (it took me two times). I turned the AC on while the manual spin was still going and it engaged and began to spin at what felt like it's normal "on" speed. However, when I turned the AC/Fan off, waited a moment, and turned it on again the fan again would not spin. When I repeated the manual hearty spin trick, fan would engage and spin. The fan feels just a touch stiff on its turning bearings. I'll oil tomorrow and see if this gets it completely free to spin on its own (or if you have another suggestion). Thanks for all your help.

Hi. Is this what you mean when you say remove the "inside control panel"?

Hi Friends! Air conditioner turns on but won't blow, in fan mode or in AC mode. And after a minute or so, overhead AC just rumbles off all on it's own, and stays off. I imgaine it could be a number of things, but if it's not blowing period, could it be a malfunction/broken fan? Besides getting a Pro to look at it, anything I can do to try and fix (at least the fan prob)? I've removed the inside filter/cover inside the cab, but haven't climbed onto the tall tall roof to investigate. Thanks! Max 1989 Micro Spirit Connected to 30 amp shore power so all good on electric

Any 1989 Micro Spirit Owners Out there? In Texas? Or thank my lucky stars in my hometown of Austin??? Just got my Micro Spirit and would love for a seasoned owner to give the operational low down on every little thing with my motorhome - very (reasonably) willing to travel to to said "seasoned owners" location for a primer. From this site I downloaded a pretty good 1992 Dolphin pdf owner's manual that is pretty close in configuration and operation and have already learned quite a bit. This forum, too, has been a terrific source of information. Of course, if I could locate and download the 1989 Micro Spirit Owners Manual, that would be great (if someone has some info on that, please pass it along). Mine's a 1989, but I imagine a 1988 or 1990 would be more than good enough to look and learn so'z I can hit the road with the necessary confidence and knowledge. Best to all! ATXBreeze
