Coleman Mach III Advice

[Bilgerat]

I need to replace my 2 speed motor for the rear A/C unit, bearings are bad.
I have removed the motor, ID Tag is bleached white, there is no stamped info on the motor casing. Can not read the ID Plate on A/C Unit either.
I have contacted Fleetwood, I have a part Number 134630. The Tech did say they show only one motor for both front and rear A/C Units.

Can someone recommend an online retailer who gave good service and a sound knowledge base?

NOTE: Amazon provides motors, NONE look like mine, which has a flat square padded plate (mounts to motor, and attaches to motor housing); amazon has motors that have; 3 mount straps, or base mount, or no bolt threads coming out of motor to attach flat plate.

I will also purchase a new capacitor.


If on the outside chance anyone knows of a Electrical Shop that rebuilds motors in the Southern Maryland area, or Richmond Virginia area I would be glad to give that a try. Seems like that is another dying art. The guy near me in La Plata MD closed his doors last year.
Thanks,

Recommend you call the local RV repair shops - when an A/C goes bad they trash the entire unit. You may be able to salvage a good motor.

Thanks Steve, we live in our rig FT, I plan to order new or have the old one rebuild. I am primarily looking for advice for a mail order outfit that has proven good service. My experience with ordering parts online has been limited to Amazon, but I can't determine which motor is correct for my unit on Amazon.

I replaced mine with Fasco D1094. I purchased one from Ebay and my second one here.

$91.95 - D1092 Fasco Motor 1/3 HP 7184-0156 1468-3069 7855MVA-A11U

It did not come with a cap so make sure yours is good.

I am unable to leave good enough alone and added a TXV valve to mine.

Try http://airexcel.com. They're the manufacturer of Coleman A/Cs - suspect their price will be higher but may clarify which motor you need.

Darn fat fingers - the site is Airxcel | AC, Heating & Appliances for Industrial and Personal Use

Thanks SpyderRV, I have page marked the site you sent.
I had contacted Fleetwood earlier the Rep told me for my year Pace Arrow the Model Number of the A/C front/rear units were the same. I am lucky that the 3 previous owners Saved All Paperwork that came with the unit. I even have the Build Sheets. In one of the 4 warranty books, lists of dealers USA Wide, was a warranty card that was not mailed.
So I now have a Model Number to ensure I get the correct Part. Sorry I didn't know what a TXV was. Had to google it, did this make a notable difference?
Just curious, since I am ignorant to that, I will just be happy to get her running.


And Thanks to Lv2Roam, Besides a great big laugh trying to find on a Cosmetic site "Where The Hell The Electrical Department Was" , really, I don't get many burst out laughing. I finally went back to irv2, and saw your corrected post.
Anyone reading this if you own a Coleman, I would page mark it,
I entered my Model Number, and received a Updated Model number to assist with locating the correct motor.

Thanks So Much, I Hope Everyone Is Having A Good Day.

Thanks spyderRV,
The link you sent was Right On The Money, the Tech I spoke to was very knowledgeable, and at just under $92 plus $11.02 shipping was a great price. Will be here this Friday.
Have ordered 2 new run capacitors and 2 hi volt start capacitors. When my friend comes this weekend, we will take care of both A/C's.

I want to let Folks know my experience with CHS Electric Motor Supply, was Fantastic.
From the time I spoke to the Tech (He answered the phone), until this morning, when I went outside and saw my new motor, I Have Been Impressed.

I called Tuesday the 16th of May, placed my order, was charged $11.08 USPS Priority Ground, received an email 1 hour later from their shipping department with a tracking number, checked the order yesterday morning, said it would be delivered the 18th by 8:00 PM. Today 18 May 8:45 AM, with coffee in hand there was my motor. We install it this weekend. I Highly Recommend CHS.

For spyderRV; I see you installed a TXV Valve and port to access your system.
My friend has recommended since I have done both A/C's; cleaned both Condenser and Evaporator, replaced run/start capacitors and installed a Super Boost to each A/C. That I purchase another motor for the front A/C, and allow him to install Bullet Piercing Valves on each A/C so he can vacuum and charge the systems. I have to say I'm Not Passing This Offer...
Thank You for including the pictures, it's what gave me the idea.

I wouldn't open the system unless it has a leak, in which case the leak would have to be repaired than a pumpdown and recharge would be called for. Those piercing ports have a tendency to leak. Moreover, if it has leaked and needs this type of repair, it would most likely be cheaper to replace the unit. Labor would be nuts. I only did it "because I could!" It won't have any more cooling ability but it will be more efficient and less likely to freeze.

I guess I never learned the lesson, "If it's working, don't oink with it!"

SpyderRV, took your advice about not using a bolt on piercing valve to check/add Freon. I had not planned on the TXV (like I said had to google to see what it was).
My friend came over today, he installed the new motor, we cleaned the evaporator & condenser on both units and made minor repairs to both covers.
During his inspection of the front A/C, he found the compressor start/run capacitor had (blown it's top). Really, what luck, it was running fine 2 weeks ago, on my inspection, seeing all the dirt on the condenser, I thought it best to stop running it and wait until this weekend when we had planned the maintenance.
The final result is over a 20 degree difference from outside to inside air temp on both front & rear units with temp gun.
Hope whoever is reading this is Well & Happy, our days in Southern Maryland are numbered, we plan to be heading to "The Farm Campground in NC", about 6 July.

Most AC compressors don't have a start cap and function fine. I suppose these ACs have them standard to address questionable power sources, That being said, my rear AC start cap had burned the top and occasionally it would short on and drag down the gen to the point it would stall. However when the cap was not shorted the AC would start normally.

[spyderRV]

I forgot to add to this thread that I removed the hard start caps on my ACs and used what is called potential relays. They look at the start winding and when the motor is spinning it removes the start cap. It does not to need to wait for the traditional hard PTC start caps to cool down to work. It will start immediately after shutdown and remove the start cap once the compressor is running.
