Compressor stops suddenly....and then starts again
My compressor will stop for a few minutes. The fan will click and turn a half a rotation and stop. This will go on for 5 minutes or so and then the unit starts up again. Is this a capacitor problem, electrical short or a freon problem?

Re: Compressor stops suddenly....and then starts again
Most condenser units have a fan capacitor and a compressor capacitor and some combine it into one,take your cover off and look to see what you have,i'am thinking it the all in one and it should be replaced,let me know-mike

Have you watched the compressor in action? The compressor is driven by the fanbelt which turns a pulley on the compressor shaft, but there's an electric clutch that disengages the pulley from the friction plate attached to the compressor shaft. You should hear a click when the clutch engages and disengages. Do you hear that? Can you see the friction plate turning with the pulley or does it stay in one position while the pulley turns? If if works for a bit then stops turning, you may have a damaged friction plate such that it doesn't engage with the pulley. Take your car to an auto A/C specialist and let them examine it. It's also possible that the relay that sends 12 volts to the clutch is intermittent and needs to be replaced.
Either the fan motor
the fan control relay
or the fan control relay switching transistor
the unit is re starting because the gas is not getting cooled
If competent check for voltage at the fan and work you way back
Hello Sounds like the condensor fan motor is going bad.If the fan stops turning or is not turning at full speed, the compressor can not give off heat to the condensor.Which will cause it to shut down on high heat.
So i would start with a new fan motor.Your local heating and cooling supply house should have these in stock.
turning ac on,there are two switch on control panel of ac.find the thermostat control this signifies the room temperature you want,set this first to a maximum setting.another switch is for the motor compressor and fun motor.rotate the switch to fun first after a couple 15 second rotate again the switch to lo cool setting w8 for 10 to 15 sec. then rotae it again to hi cool there will be a sudden heavy change of blwing air and cooling effect then rotate set the thermosat switch to temperature comfortable to your feeling,observe the cycling process,because the compressor motor stop if the room temperature reached the set up temperature.stopping or switching off just rotate the switch of the compressor motor on off position.have a nice day fix my rate thank s a lot.
Low freon will usually cause a freeze up, your sounds like an overheat shut off, compressors get hot, but if the get too hot there is usually a safety shut off... also, if the compressor is wearing out you can install a hard start cap inline with the compressor to bang it into operation. It would make an unusual humming sound if your compressor is not turning... capacitors are inherently dangerous when charged, so you may need someone to install it for you. The caps are not expensive.
It appears you may have a bad fan motor the reason the compressor stops is it is kicking out a low pressure switch to protect the compressor. You may be better taking it to an RV shop because I think you will have to remove the evap coil to change out the fan motor.
-If both compressor and fan motor starts and stop, thermostat is the defect. - If only the compressor check for your outlet no sign of discoloration, check the voltage if normal, check the defective overload protector of the compressor it its external, or compressor itself is defective
