Fedders wall air conditioner

What you describe is what window air conditioners do.

Bied I need to ask you does it reach temp to shut off?? how do you know ? is the fan shutting down inside .

Hi,
The unit is probably low on freon and so it is running too cold....this trips the freeze stat and shuts down the compressor till it warms up
The unit will need to be recharged or replaced...

Here is a tip that I wrote about how to add refrigerant to a air conditioner or cooling system

How to add Freon to a Air Conditioner or Refrigeration System

sounds like fan motor has gone bad or the capacitor to fan motor is bad...open up unit ,see if motor is frozen..does it turn freely..if so ,replace capacitor,or fan motor is bad...

Looks like micro controller problem. Contact service center for assistance.

you have to open the unit up or atleast see if the fan is failing. The blower motor is usually a double shaft and cool the compressor and also blows the air across the evaporator. Look for the air to stop blowing then the compressor to shake from overheating.

follow the wires from compressor to contactor or relay contacts stuck replace

Oh, the compressor motor's borked or overworked and overheating, or its capacitor failed short (perhaps the motor is shutting off from thermal shutdown...but you get to find out whether that's so. Be safe.) Alternately the temperature sensors have gone touchy on you. Once you gently vacuum it clean, try keeping incandecent bulbs in series with the compressor to get an idea of how loaded that thing is as it runs for those 5 minutes or so; the load might change more than you expect, just pay attention.
Hopefully you won't have to replace the compressor or motor; but it's doable if you're a certified technician with like equipment (so you can handle the refrigerant decently.) Most shops will streamline a bunch of similar jobs together to cut the waste and setup time.
Bigger conditioners are so much more efficient than little ones...syndicate the A/C?

You could have a relay stuck closed, so every time the power is on it feeds electricity to the compressor.

I would try to start the unit with only the fan running at first. If it stays running then cycle on the compressor and see how it does. If the unit does not operate when compressor is turne on then we have to dig deeper into that.
