The capacitor's for running, too. The resistor across the capacitor is supposed to be warm but not hotter than boiling. Just disconnect the capacitor and check for a short if you suspect it; but it would be warm someplace.
The timer unit is usually reliable, but if it permits a thermal cutout after 5 min. and the cutout device is a little skittish, it could be either that cutout or a hot-side cutout (or thermostat) failure. Replace, don't bypass.

The Fedders window unit A/C is making chirpy bird noises when it is first turned on for about 20 min. or so. What is the cause?


Usually a dry bearing somewhere. You need to fix it. If it is in the compressor rather than the fan, it is probably uneconomical to repair. It is better if the chirping STOPS after 20 minutes rather than STARTING after 20 minutes. Heat and use is fixing the problem for you.

I have a fedders window unit 220v 18000btu. The ac side works great but when swapped to heat it just blows cool no heat. The filter light starts flashing as well in heat mode


Those window units usually have a strip heat kit that supplies the heat. You might want to have a technician open up and check heating circuit.

Comp shuts off


Coils could be dirty. Compressor could be getting too hot and cutting off. Will have one fan motor that turns condenser fan and evaporator blower.

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?

Air conditioner problem


You may have an extremely intolerant cold control, a weak gaurdette on the compressor, a compressor motor winding issue, or maybe an oversized unit for the area you are trying to cool.

Fedders Window AC Unit


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.
