Its getting warm out....I need A/C

[Bearmechanic]

OK, my OEM Armstrong Model (BA(?) 0-110-1) series D-D9, Serial # 62955. Fan is froze up. I went on top of my 1969 27' Overlander International (some say it's an Ambassitor trim level) and checked for Mud daubbers ECT. I saw nothing..clean as a whistle. When I flip the termostat on, I hear a buzz, and then nothing...I know that the compressor is trying to work, but I think that due to the fan not wanting to turn a relay is stopping it. A few min. later it will buzz again and then stop.. Any one know how to free a fan motor, or at the very least tell me how to get the lower cabin fan blad off so I can take the fan to a small motor shop and see if they can re-coil it and get it running? Email me at mtownbears@att.net, for some reason folloe up postings don't want to coem to my email box.
Thanks in advance

Do you have full voltage going into the trailer? If you do, it sounds like perhaps the hard-start capacitor has bit the dust. You can remove it, and take it to someplace like Grainger, to get a replacement. the replacement will be much smaller than the original.
If a new capacitor doesn't fix it, you probably need a new compre$$or.

If the fan blade is hard to turn you may just need to oil it (not all units have oil ports).

If the fan turns freely then you need a new start capacitor.

To test you can use a stick or something to get the blade turning when someone turns the AC on and it should continue to spin the start capacitor is just used to start the blade turning.

Does your a/c have one or two fan motors?

Thanks, everyone..I do have full voltage going to the camper, as well as only only motor. I can here the Compresssor charging, so I don't think that the Compressor is bad yet. UI just can't get the fan to turn, either by hand or by force.

You have a single fan motor that uses 2 blades, one inside the trailer and one within the unit on the roof.

The motor has seized by your desciption. That can be from rust, a burn out and/or a seized armature shaft caused by lack of lubing.

W. W. Grainger has replacement motors for the TAC 110 models.

Looks like a new motor or a replacement from a donor unit may get you back into business. Those Armstrong units are first class.
