Re: Air conditioner motor seized from rust
I've worked with my father in airconditioning a bit when I was young and this is common. Depending how old the motor is, there could be oil felt around the bushings where the shaft spins in. If you can get at them, soak them with oil. If the shaft is baddly rusted, you might want to take very fine emery cloth and smooth the shaft out. Just oiling it might be enough.
The one thing to watch for are brushes. If the motor has brushes, they tend to shoot out when you take a motor appart. More than likely, that motor won't have brushes but if it does, there usually small pin holes you place a pin in to hold the brushes back when you re-assemble the motor. Once together, you remove the pins.
