Question about Ruud Matching Split Air Conditioner
Have you checked the wiring going to the compressor to make
sure it is not melted? Next, are you
able to put your hand on the top of the compressor? Check to see if it is hot or cold. You might have a bad run capacitor so let the
unit turn on, wait about 5 minutes, turn the unit off, and then tell me if the compressor
is hot or cold to the touch. Next, are
you comfortable with a meter?

Testimonial: "No burnt wires. Contactor looks good. 208 volts getting to compressor. Ohmed from grnd. to all compressor terms... No short to grnd. Approx .4-.8 ohms across run/start/com. Didn't check temp of comp but I'm sure It will get hot if internal overload is kicking without a full start. It seems this could point to run cap or locked compressor."

SOURCE: Compressor will not start.
If the unit is low on freon it will short cycle but a compressor internal overload will cause it to. Lets hope its the freon. Has it been frezzing up lately. Low freon is the cause most of the time. Make sure your filters are clean and both fans are running. Hi head can cause this to. (fans not running) How old is this unit. Maybe the coils need to be cleaned. Sound like this unit may need a check up and a good cleaning.

try spinning by hand when the unit make the buzzing sound. to see if the capacitor is bad. If the fan runs replace the cap. If not motor probably is bad. See if it spins freely. this is a good starting place. need to check if the buzzing is the contactor and there is no power to the condensor. The contactor will buzz even though the main breaker is off or tripped

Check your disconnect or breaker that is located close to the outside unit. Next you need to check the contactor in the outside unit. Set the thermostat to make the air come on then check the contactor. It should be pulled in closing the contacts. If it isn't the problem could be the contactor or thermostat. Next check the voltage on the load side with it pulled in. If that's good then check the capacitor. If it looks swollen, it's bad. You can also use a multimeter with the capacitor check function to do this. Let me know what you find.
