Coleman rv roof air conditioner

That should be a 30,000 Btu unit. Its been a while since I worked on them. The 78 is the series or model, the 30 is the capacity or btu's and the 901 indicates it is a Copeland compressor.

If you Google airxcel.com, you should get some options. to get either their literature or tech support and they should be able to help you.

Check fuse in rv, and thermostat

Re: re-directing the water dripping over door ! Stop at RV parts store and get yourself a tube of "Dicor" self leveling sealant. It's recommended for rubber roofs, but works well on most roof surfaces.
Then I simply run a 3/8" bead of "Dicor" across wherever the run-off from AC is coming down, and re-direct it so the run-off comes off roof elsewhere. Don't try to smooth it out or anything, as I said, it is self leveling, just use a caulking gun, lay a bead about 3/8" and allow it to set for a few hours if you can. Make sure you pick a time where AC is off for a couple hours so (run-off) water isn't present. You"ll see the path (stain) on roof where it travels to guide you for redirecting. It's a simple fix, and no screws or nails required. Use the rest of the Dicor to fill in any gaps, cracks etc you see on sealant on the roof while your up there, but clean those before applying. If you can wipe your intended path down with some mild cleaner prior to applying bead, it will help it stick better as well. Even a little dish soap in water will do, just be careful, it gets pretty slippery when soap on there. Quick rinse with water then dry with rag, or let the sun dry it. Actually on a rubber roof, It should be scrubbed with mild detergent at least once a season anyway.

well check a few things first....have someone remove the cover and reach in with a hand and try to manually spin the blade...free spinning?....then tell the person below to click in the on postion while someone views from up top.....is it humming? or even trying to spin?....if not check the fuse on the RV that protects the A/C unit.....good?.....now replace the capacitor ( it the silver or gray can looking thing that the motor wires run to) only the correct size will work w/o causing further motor damage.

Looking for a coleman thermostat number 7330-3351. Anyone know where I might find one. It is for a Coleman 7300 roof air.
e mail at [email protected] thanks

there are 2 drains on most units one each side about 6 inches back from the front of the unit - they are white plastic and have a small hole in the side - they may be clogged - happend to mine - used a paperclip to clear out now work fine - good luck

Capacitor is good place to start, once you confirm you have proper voltage getting to the unit.

***I guess nobody knows the answer. Ok. I'll search elsewhere.
