Answer: Yes and yes. It could be a capacitor, or it could be the compressor. Since capacitors are cheap it may be worth a try to see for yourself if that’s it, if not you will need a technician. There is really no “DIY” fix when it comes to repairing or replacing a capacitor.

What are the 2 replacement rules when changing a start or a run capacitor?

As a general rule of thumb, electric motor start capacitors can be replaced with a micro-farad or µF or mfd rating equal to or up to 20% higher µF than the original capacitor serving the motor. On the replacement capacitor the voltage rating must be equal to or greater than the original.
