you probably wouldnt get an oem replacement unless thru rheem dealer or distributor ---multi reasons on cap failure --dirty condenser coils--fan ---weather-- environmental--power supply interruption --- and those are the correct caps https://www.justanswer.com/hvac/b4b4e-old-rheem-model-rahe-042jas-size-capacitor.html
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.
The carburettor is getting too hot and fuel is being blocked from feeding into the engine. Make sure that the carburettor is clean and has adequate cooling while the engine is running. If you still have problems withs starting, blow the carburettor cool or use a damp cloth to cool it if starting is a problem.
I have a Sony VAIO GRS170/GRS175 in use almost every day since 2003. It used to turn off regularly during hot summer days even with its battery fully charged and plugged in. The problem was eliminated by using a small fan to blow air at its side where the air intake was located. Later, the fan was replaced with a notebook cooling pad which was more convenient. You could first try using a fan to see if it makes any difference. If you don't get anymore shut downs, then the problem is definitely due to overheating. You could then replace the fan with a notebook cooling pad.
the coolings fans are designed to run for a little while to dispense heat they dont do it all the time turn usually during higher hot days w/ac on or higher hot days goes off automatically
Capacitor, dirty condencer coil causing the motor amps to run too high. But most likely worn bearing on blade side of motor causing it to pull to one side causing it to over heat and shut down. Sleve bearings should have no side play.
When a system shuts off after about the same amount of time every time--and it can't be traced to having one particular program, it usually means it's shut down because it's getting too hot. Do you get any warnings? Can depend on chipset/settings what alerts you get. Something often overlooked is the cpu fan, if your system is a couple years old, that'd be a generally cheap/easy replacement that often fixes it. It can be very hard to tell just by looking at it if it's working normally or not. Any noise?
