Sound like the compressor overload is tripped. Make sure the condenser is clean then reset the breaker on this circuit.

It sounds like you have a freon leak and may need a charge. When there is a leak, the compressor will run for awhile but without the proper charge, it will heat up and kick on on thermal overload. After the compressor cools, the unit will come back on. Have the unit serviced by a professional.

I do know that the owners manual should show you what each and every code means? Some times the manufacture will paste a strip located on the panel of the indoor unit showing what each code means. If not, I would contact the factory on this. I know on Bryant, Mitsubishi splits, Day and night, (Bryants), Tranes, Lennox and most all others, do show in the manual and on the unit behind the panel. Try looking for them there.

SOURCE: Can you tell me how
It would be hard to say by just giving you a number in pounds and oz. The condenser is charged with enough freon for up to 25' of line set. Even though it is a 3 ton unit, they all hold different amounts, yours may have a accumalator, a liquid and suction line drier ect. If you are doing the charging your self, when there is no data plate telling the amount the unit holds, we use a pocket pressure/temperature chart. We charge the unit according to the outdoor air temperature, wet bulb, sub-cooling or in your case superheat using your manifold gauges. With the system pulled into a vac, you charge through the low side port if using R-22 watch both your head pressure and low side using the increments and pressure/temp chart that you can pick up for free at any wholesale a/c refrigeration parts house. If I new what the ambient temperature was where you were doing this, I could help you or tell you where your gauges should be, but you really need to check the superheat to make sure you are not over charged which will kill the compressor due to liquid in the compressor. I would have to charge it my self if I did not know the charge which most units will not even show on the data plate.I hope I have been of some help to you.
