Coleman roof a/c units compressor not coming on

You posted a response on note_worthy@comcast.net but my e-mail address is note-worthy@comcast.net. In response to your questions, the two units are 110 volt. As the model numbers are worn and /or illegible, here is what I come up with: Model # 6753A723 or #67536723 for one and 6799A381.

    I have  coleman a/c unit on the roof of my Palamino pop up. When I turn on the a/c unit you can hear the compressor trying to kick in but it does not. It will then start getting hot if I try too long. I'm afraid the compressor may be seized up. Any help I would be grateful.

Coleman mach rv roof ac, the fan comes on but the compressor doesn't, i've replaced all capacitors and stll is not comming on, how do i check voltage to the compressor to maske sure i have pow


At the compressor connectors you have a live and a neutral phase. The live usually goes to a ptc relay starting mechanism which you can test with a meter. If you can disconnect the relay and check the windings of the compressor from one pin to the other two it will tell you if the compressor is open circuit. It is more often than not an overload fault.

Need to know the BTU's of a coleman rv roof air.


The limiting factor is the power available to run the device. Typically, roof air units are around 12,000 BTU.

Unless your rig is wired with a 50 amp service, you will not be able to run more than you have at the present with your 30 amp service. I have found that a rig with a microwave, a roof AC and a TV frequently cannot run all three at the same time. If you do have 50 amp service, you can add the second roof air. Also, if you have a 30 amp service, you can upgrade to 50 but that is an expensive proposition with the cord itself costing around $200.00. You would also have to upgrade the distribution panel and probably have a pro properly split up the load between the two 120 Volt AC buss'.

I hope this response helps you with your deliberation and thanks for your question @ FixYa.com

How can I tell if the compressor is coming on on my Coleman 13500 roof top A/C unit? It blows air but not cooling. Thanks


Hi,
When the compressor starts you will hear the unmistakable noise associated with it...there is a definite hum from the compressor...check the t-stat on the unit... they often go bad..

My coleman mah 3 roof top will not blowon fan side


Sounds like you have either a bad fan motor or a bad fan motor capacitor. When you turn the unit on with the fan not working, the compressor (the humming noise) runs and gets real hot real quick resulting in the compressor cutting off ( the nothing after) on it's inside high temp switch. This is what the compressor is designed to do so that when this happens, it does not burn the compressor out. Replace you fan capacitor, give the compressor an hour to cool, then try it. In most cases and if I'm correct, the unit will run just like you want it to. Good luck.

I have a Coleman 6770 A Series roof air on my trailer. It won't blow cool air. Is this a compressor problem? And if so, would it just be cheaper to replace the whole unit than to try and repair this one?


Before the compressor is condemned, is it running at all? Is it getting the proper voltage? If the compressor will run and still does not cool the system could be low on refrigerant.

A replacement compressor is normally more economical than replacing the entire unit. It could be something as simple as a open thermostatic control.
