Question about Coleman Powermate Premium Plus 6250W Portable Generator

1 Answer

I have a 3500w coleman generator I use to run my 5th wheel. It works fine until I turn on the air conditioner, then it sounds like it is bogging down and will not power the A/C.

Hello, I will make the assumption that your A/C runs fine when you are tethered to shore power. You will need to calculate your load. Add up the amps of everything in use, including the A/C. 3500W is the peak momentary output; look at your data sheet or tag to determine your continuous output, which will be less. It's possible that you're either pulling too many amps for your genset or there may be an issue with your A/C. Turn everything else off, and start the A/C. If the generator bogs down, you may not have enough generator. If it doesn't bog down, turn on your other items, one at a time. Ideally, your generator should have enough output to power everything in your 5th wheel, plus ehough extra for initial starting surge, like for your A/C, fridge, etc.. It sounds like your amps are close, but not quite there.

Sounds like possible fan capacitor failure. If your not familiar with capacitors, please find someone who is, as they can give a fatal electrical jolt if not handled properly.

When you put a load on generator it powers up and down and tries to cut off.


sounds like you are trying to put too much of a load on your generator. I have a 3500w generator and when I hooked it up to my 120v (not sure how many HP) well pump when the pump would try to cut on the generator would bog down and even die. took off the load and started right up. will run other things just not heavy loads. maybe you need a bigger generator for what you are trying to power.

The issue with the generator that gets low and high when it start running out of gas that effect the A/C and result of high voltage getting to the unit and burn the capacitors and it should by saved by the fuse make sure that the gen not run out of gas if you have the A/C on and that the fuse is the correct one for the A/C and again check the air and see you may got a bad capacitor.

Coleman TSR Mach air conditioning roof mount trips breaker


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.

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,

Jeff

You may have a power supply problem. If you are connected to an external power supply with a cord, make sure it is able to carry the necessary power. To small a cord will cause a voltage drop giving insufficient voltage to run the compressor. The noise you hear is the refrigerant pressure equalizing in the system after the compressor shuts down.
