Edgestar AP550Z - Noisy, Not Compressor, Flywheel?

My Edgestar AP550Z has been working fine up until last night. It still heats, but when the blower starts and the flywheel begins to turn (not sure of terminology, but it's the black rotating cylindar that can be seen through the vent next to the motor housing at the bottom back of the unit) it becomes extremely noisy.

Looking at the 'flywheel' while operating it appears to be wobbling as it turns, causing it to hit against the side housing of the unit. I can't figure out how to access it to stabilize it again, nor do I know what I would use to stabilize it. I assume there may have been a spacer of some kind on the side of the wheel that may have broken, although I haven't found anything outside the unit that looks like it came from there.

Suggestions on what I can do or what I can use to keep it from wobbling and shut it up? (Last night it would eventually quit banging after a few moments, I assume from finding equilibrium in its spin. Today, no luck on that.)

Please read the problem carefully and address the problem. These reponses fail to do that! The problem is in the balancing of the circulating exhaust fan which is like a hamster wheel lying on its side. Once this begins to make noise, it is due to breakdown completely. This is a problem that should not happen and is built in obsolescence. It needs to be maunufactured stronger.

SOURCE: edgestar AP550Z won't heat, goes into some sort of alert mode
This could apply to at least one of your units. Apparently these models have had some trouble with the compressor capacitor wires coming loose. If they're barely touching they could cause the compressor to run intermittently and possibly overheat. The compressor runs in heating and cooling mode.

There are 3 possibilities beginning with the most likely problem

1) If your heater heats up for a few minutes and then quits, chances are there is a blockage in the air flow, check for dust and grime blocking the air intake coarse filter , airgun blow to clear accumulated dust and otherwise clean the coarse filter .
2) If the heater fan blows but there is no warm air, the heating element needs renewal ( this happens very rarely)
3)If the fan stalls and the heater heats up and the thermostat kicks in, then this will be not be a DIY job. This is least likely as you said the air cooler works.

Air worked fine all last night and his morning.

if the air comes on for a short time and then turns off for 15-30 minutes, the overload protection inside the compressor is shutting down to protect the compressor. this can be caused by blocked supply or return vents, improper charge, bad valves in the compressor, and a multitude of other things. the problem will have to be corrected first.

Possible Contactor Issue

Sounds like a bad fan switch in your unit. That unit has a fan board in it that is time delay on and off. Turn the fan to the on position and let it run all the time. If it keeps temp and does not shut off it is the fan realy board. The board also controls the compressor. Check that first and then the tsat. Russ

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.
