Question about Coleman Mach 15 Air Conditioner

Coleman TSR Mach air conditioning roof mount trips breaker

I just got a 2001 5th wheel with a 13,500 btu Coleman TSR Mach A/C unit and it runs fine with just the fan on. When I turn on the cool air it overloads my generator which is a Honda 3000 EUI with a 23.3 amp connector. I ran an extension cord from my house to the 5th wheel and it trips my house breaker also. Any way to troubleshoot this? I am an auto mechanic of 23 years and want to try fixing this myself before I start paying $100.00 hr to shop.

    If you read my listing you will see that I have pugged it in to my house and it still trips breaker. I removed the overload switch on top of the compressor and now everything works fine. So I am going to order a had start compressor kit and replace the overload capacitor also. Everything will cost $30.00. I will let you all know if it works on Friday when the parts come in!

The simplest answere to start is it' looks like the compressor is the ssue." Either it has siezed"or in my oppinion needs a proper household power to activate it. If the voltage drop on these units is a little below a certain value, it will not start and will burn out. Thats why i suggest a household power be tried first. I feel your generator is a little undersized. You will only know once you have applied household power.

Coleman tsr rv air conditioner leaks into rv when running


It probably has a clogged condensate drain. Take off the cover on top the RV and check hoses or tubes leaving unit for debris or lint. Often this water is used to help cool the condenser so look for leaves pine needles etc in the pan. There may be a cover you can remove on the evaporator section that will allow you to clean the collection pan and hose or trough. Is it possible the RV is far enough out of level that the condensate can't "run uphill"? Always power off while working on this unit unless you are electric savvy. Good luck!

Coleman tsr mach 3 RV Air Conditioner


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.

the fan motor bearings need lub....the shaft has a tiny access hole to put some oil into. because the fan shaft is slowing down, it is putting more strain on the voltage current, and eventually the internal breaker shuts down the ac........plus your condenser is not getting enough air accross it, compressor heats up, and it too will shut the unit down......older units have to be oiled every year, and eventually it too will fail, and a new blower motor assembly is needed or replace the ac unit.....blower motor units are around $130....now you install it or pay to have it done at around another $150 labor,,,,,try yourself, if it fails then call the tech........let me know ..ray..yyzazz@ao.com
