I Need an Info Source for Too High AC Capacitor

Hello all...I need a reference that shows that using a too high AC capacitor will burn up a fan motor.

Company 1 came out one evening because our central AC wasn't working. The capacitor in the outside condensor unit was replaced. After this the fan would operate for about 30 seconds after the AC was on, then it would cut off. A 12.5 mF capacitor was put in when a 5 mF was called for.

I called Company 2 for a second opinion when Company 1 tried to tell me I need to change the whole ball of wax. Company 2 noticed that the capacitor was the wrong one. I got upset and called Company 1 back and told them what Company 2 said. Company 1 claimed that a too high capacitor would NOT damage the fan motor but I know that this is untrue.

That is why I need a reference to prove to Company 1 that their over-mF capacitor burned out my fan motor. Thanks a bunch!
