Hello, sounds like the motor is opening on it's internal overload, This could be due to either a bad run capacitor or open motor winding. If you have a meter you can check the resistance of the motor by turning off power to the unit and placing one meter lead on the purple wire and the other meter lead to each other wire one at a time, you should have resistance if not the motor has a open winding and needs to be replaced. If the motor is fine then tne run capacitor is the problem and must be replaced.

Why is my air conditioner unit only running properly on cool days? when its hot out it only runs about 5 mins at a time then shuts off to fan and dont come back on for another 20 mins.


Do you hear a click sound as the compressor shuts down? If so that is the clixon (heat sensitive circuit breaker) that is opening and shutting down the compressor when it overheats. You have not had the AC filled with refrigerant so overfilling the unit cannot be an issue.
And if it is not overfilled overheating is caused by excessive current going into the motor which could indicate a problem with the motor windings..

OR, If the thermostat is faulty it could be prematurely shutting down the compressor. If you jump (bypass) the therm and unit does not shut off then you have found the culprit.

Condenser Fan Shuts off after 15-20min, Compressor continues to run but gets hot


Condenser fan motor or motor wiring is bad. That compressor should never run without the fan. Good luck.

Fan condenser unit wont run


This is usually a bad capacitor or bad fan motor. The capacitor is located inside the electrical panel on the outside unit. You can check these by using a meter that measures Mfds (Microfarads), most of the time you can visually see the capacitor swollen or blown. The fan motor can be checked by a meter that measures ohms, really high ohms are usually bad. If you can't spin the fan blade easily, then it's locked up. What usually happens, the capacitor or motor windings go bad, doesn't spin the fan blade, overheats the compressor so it kicks out on thermal protection till it cools back down, and sometimes the motor will overheat and go into thermal protection also. Just make sure you are getting the 220v to the outside unit too, but shut all power off before doing any trouble-shooting. Hope this helps, feel free to ask any questions!

I wired up my replacement fasco motor for my condenser fan and it ran for maybe 30 mins and shut down. It was very hot and wouldn't come back on until it cooled down. I wired it like the dealer told me,...


Tough to answer without more information. Most likely the speed of the motor is too fast for the fan which causes unnecessary load on the motor causing it to overheat and shut off. Likewise the motor could be underpowered causing the same thing. I would bank on speed. The squirrel cage blowers have speed limits and won't go any faster regardless of how fast the motor can turn. Check the speed rating on the old motor and compair it to the new one.

I have 1997 mercedes-benz E320, the ac blows cold at 35 mph and over but warms up under that speed, i tried charging system last year but it acted the same


Check if condenser fan is working.
When a/c is on , electric fan on the radiator should come on.
If it's not , system may overheat and shut down , when you move there is natural air flow through condenser , when you stop , if fan is not on no air flow (cooling) through condenser , system pressure rising and safety switch shuts off the compressor.

Compresser overheat triping


Hi!!

It could be a few things that make the compressor overheat, when this happens, the bimetal thermal protector shuts it off to avoid damage to the unit.

Some of the reasons could be:
Dirty condenser and/or evaporator (if condenser is dirty or clogged up, the heat absorbed by the evaporator will not be dissipated, this will cause the compressor to overheat.)
Bad fan motor.(not blowing enough air to cool down condenser).
Bad capacitor (only if compressor fails to start right up or not at all.)
Worn coils inside compressor.
System clogged or dirty. (If the system is dirty or clogged up, the compressor's workload increases causing it to overheat.

Don't forget to rate this post, Good Luck!!

Cooling fan in condenser sometimes does not run.


Shut off the power before inspecting or repairing! I would check the wiring harness inside the condensor unit for loose connections and or broken wire first. Then you might try removing the capacitor to the fan (some operate both the fan and compressor) and have it tested. If all is OK then your fan motor is probably overheating and may need replaced. A bad capacitor can cause the motor to overheat. If you had a lightning storm just before the problem the capacitor is most likely the problem.

Compressor hums and shuts off


This sounds very much like a compressor failure. unplug the refrigerator and check the condenser for cleanliness. After cleaning the condenser and allowing the compressor to cool, plug it back in and listen for the same sounds. If the compressor was overheated it should restart after it cools. If it does not restart the compressor could be seized. Check the compressor warranty against the age of the refrigerator.
