Question about Coleman Mach 15 Air Conditioner

2 Answers

Coleman rv a/c

My a/c works fine unless it's HOT outside. It will run great for 1/2 to 1 hour, or until the compressor cycles off. When it stops running, it suddenly slows down, dragging the power with it until a breaker trips or I turn it off first. Then it will not restart for a half-hour or so. I can hear the compressor humming, cycling, trying to start, but it will not start. Problem happens in both high or low cool settings. Works fine in cooler temps. Blower fan runs normally at all times. I'm no a/c expert, but it acts like the compressor is building too much head pressure. Suggestions??

It is definitely with the compressor. It should more like you may have a weak winding in the compressor, you can a hard start capacitor (sp5 ) that will help the compressor on restart. Note that this is a last chance solution for a compressor.

Compressor on my RV coleman ac unit bogging down


Take a look at your start capacitor. This the capacitor that kicks the compressor over when it tries to start. If the capacitor is bad, it cannot kick the compressor back over after the first cycle because the head pressure has not evened out yet. It is located in the upper unit on the side panel in a small box. Be careful, highly charged capacitors can zap you if you are not careful. Disconnect power and touch across the terminals with a meter or a screwdriver to discharge the capacitor.

Hope this helps,

Fan stops


The cooling fan for the condenser is probably running, getting hot and seizing up. Check to see if the fan is free spinning after it stops. Take a probe and try to spin it manually. If it turns freely, then it could be going bad with it's electrical windings, the internal coils that create the magnetic field that spins the rotor of the fan motor. I suspect it is seizing up, however, once a fan seizes up, it usually stays that way and won't spin even after it cools down. It could be a capacitor that is going bad and not starting the fan after it gets hot. A capacitor is a small round shaped can type with usually 2 wires hooked in series with the motor it is trying to start. That is what it does, help start the device (compressor or fan motor). Good luck.Ken from Henderson NV.

Compressor will not come on. Fan runs great.


I fixed it. I had a dirty connection on the starter relay for the compressor. Thanks again for the help.

I don't think you need a new one just a good cleaning and service. The unit has a liquid high temperature line near the compressor with a fan blowing outside air across it this coil gets clogged over time with air-borne dirt and pollen and leaves and such and must be cleaned regularly or the unit will be unable to remove the heat from the coil and during the peak demand (3pm) the circuits that protect the compressor and the trailer wiring from being overloaded and burning or melting will trip. From what you have described it sounds like the RV is working as it should with a condenser coil that needs to be cleaned. GL and happy camping!
P.S. I've only serviced the occasional RV unit but in those cases I laid a piece of plywood on top of the Rv for work platform removed the retaining screws from the top cover and used a spray bottle with a good heavy foaming cleaner a shop-vac and a brush to get the job done.
