My goodman split unit make a load buzz almost like it is stuck and won't go off after satisfying the stat. It stops as soon as I either raise or lower stat either up 1 degree or down 1 degree it is also sporadic doesn't do it every cycle any other ideas?

Where is the noise coming from? Inside or outside?

The noise is coming from the outside unit ! Its like a bad vibration or roar..

Possible bad bearing in motor.
Loose or defective fan blade.
Vibrating contactor.
Loose fan motor mounting.

A noise is very hard to hear because I am not there. So this is a guess.

Thank you.
