You have contactor problem. If the fan does not come on when you put the unit in off and fan only. You have lost your 24 volts. To repair you must replace your step down tranformer.

Air conditioner compressor will not start. When power is applied to the air conditioning outdoor unit the fan starts, but you hear a sound like the compressor is trying to start, "UGGG"..., for about 5 to 10 seconds and then all you hear is the outdoor condenser fan run. The compressor is locked and will not start. What is happening is the compressor is trying to start, but because the compressor motor is locked it tries to start for a few seconds and then because of the high amperage being drawn goes off on internal overload. The internal overload protects the compressor windings from overheating and burning up. I see this many times during the start of the air conditioning season.

I need help with a buzzing sound in my air conditioner.


It is probably the compressor humming. They can make some funny noises especially on start for a while. If the unit is not cooling it may be the start capacitor or the comressor may be locked up.

Ac not on but humming


Sounds like the contactor inside the condensing unit is stuck closed. Once this occurs, it should probably be replaced, as this kind of condition can lead to compressor damage if left unsolved.

Heat pump is humming loud>


When the heat is not on. Go to the T-stat and turn the fan to the on position. With the blower now running is it making the noise? If so you probably either have something in there such as the filter that was mentioned, a piece of paper etc. or one or more of the blades on the blower wheel is vibrating. Don't let the condition persist w/o having it checked out or you may turn a simple fix into a costly one.

Hi,

Fan problem could either be the starting capacitor or the motor itself. Often it would just be the capacitor and you could verify this by a humming/vibrating sound coming from the motor as if trying to turn but is not capable of. If it were the motor burned, the unit would have excessive current tripping the breaker or a fuse blowing.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

MY AIR CONDITION ONLY PUT OUT WARM AIR EVERYTHING SEEMS TO BE OK FILTER TURNS ON OK BUT THE OUTSIDE UNIT HUMS BUT DOES NOT FAN


Sounds like a bad start run capacitor. The exhaust fan motor may be bad too. Be careful, this unit delivers 220volts of electricity.
