The compressor would not run.

I removed the screws in the lower back panel where the compressor is located. Then I unplugged the capacitor and plugged the new one in. I then checked to see if the compressor would start. It wouldn't so I replaced the overload relay with capacitor and that fixed the problem. The capacitor just plugs into the relay then plugs into the compressor. There are several screws but all in all it is easy.
