There are a lot of regular hums on an outdoor unit: the fan motor, the compressor, the electrical contactor, etc. There is a lot of air movement, and a fair amount of vibration from all these things.
My outside fan tries to start up but goes off in a second. I replaced the dual capacitor, fan and compressor, and it worked fine for one night. Now it starts for second and goes off again. The capacitor is tested and fine. What could be the problem?
My outside AC unit starts running then stops. I hear a buzzing noise, then I hear no sound coming from the unit. What could that be?
My inside ac unit blower motor went out ... can that make my outside unit stop running as well?
I replaced the capacitors so the outside fan of my air conditioner would operate properly, but it is still not working. Is there anything else that I could check or try?
The fan of my AC is working, but I hear a buzzing noise when the compressor should turn on, and then it doesn't. Is this a capacitor problem?
I followed the steps, however, the hum was not coming from the capacitor. It is another component of the cooling pipes, what is that?
