Ac will run for a while then blows breaker, not so much when cool out side but when its hot out dont take long? start capacitor?it duo therm 57915-009 briskair
i think compressor junk tried changing start capacitor today didnt help .thanks why couldnt these units be servicable like a vehicle i think compressor junk tried changing start capacitor today didnt help .thanks why couldnt these units be servicable like a vehicle

HIGH PRESSURE CUTOFF SWITCH LOCATED ON AC COMPRESSOR DISCHARGE LINE LEADING TO THE CONDENSOR.THE HIGH PRESSURE CUTOFF SWITCH WILL CUT OFF THE AC COMPRESSOR IF SYSTEM PRESSURE RISES TO HIGH CAUSED BY RESTRICTION IN THE REFRIGERANT CIRCUIT OR OVERHEATED CONDENSOR.MAKE SURE COOLING FAN IS RUNNING WHEN THE AC SWITCH IS ON.THE COOLING FAN KEEP CONDENSOR COOL, IF COOLING FAN DONT RUN.YOUR AC WILL STOP BLOWING COLD AIR.HAVE THE REFRIGERANT SYSTEM CHECK OUT.MAKE SURE YOUR LOW SIDE PRESSURE IS 10 - 37 PSI. THE HIGH SIDE PRESSURE SHOULD BE 112 - 210 PSI. CHECK THE AC COMPRESSOR CLUTCH FUSE AND RELAY.
make sure your electric cooling fan behind the radiator
is running with the a/c on , if not tap on the back of the
housing with a blunt object , but dont break it .
if it starts up , its the motor , if not ,a fuse or relay.
If its not running , repair it or dont use the a/c , as
the high pressure can dammage the compressor.
you need to check the breaker for the outside unit. feel the top of the unit if its hot turn off the theromstat and let it cool retry and see if yu hear any noises coming from outside like its trying to start. could be a bad capacitor
Sounds like the thermostat is trying to stick,and is causing the engine to over heat,therefore condenser is not cooling the freon down enough to cool.Have the thermostat changed and the cooling system bled out,this is most likely the cause.
The condensor fan should be sucking air from the top and blowing it through the coils, probably a counter clockwise direction. The buzzing/humming sound is confusing to me. A humming sound sounds like a motor that can not turn over to start. A starting capacity would be needed. Just because you changed it out last year does not mean it is good. A buzzing sound sounds like a contactor problem. Contactors buzz and after a while, they will fail. In any case, you can "stick start" the condensor fan PROVIDED you are sure the ac compressor is working (this is for a short and temporary use). Also, you may have a high load duty capacitor that assists in the unit running. This will affect your condensor fan operation if it is not good. Unless you know all the components and operations of ac electrical, I would highly recommend calling out a professional.
Sounds like your Capacitor is bad, or you had a wire burn off compressor terminal or capacitor. Way you can check capacitor is take cover off and see if looks swollen. Make sure to turn off power before taking panel off.
Check to see if your outside unit is running. If not, check the breaker. If it is running you may have an issue with the reversing valve. It looks like three lines coming out of the top and one on the bottom. Trace the wires back to see that they are tight and secure. Of course, TURN OFF THE POWER first. good luck.

try a hard start capacitor
