I have a Hammond H-100 that was left on for an entirely too long period of time (by mistake). It emmited a foul odor and I turned it off. Now when i turn it on the amps power up but the synchronous motor (?) is not turning, causing no sound. And it still smells. The motor is not stuck; it's just not moving. I traced the power switch wires to a transformer which led to this motor. Could there be a problem with this transformer or is there a more obvious answer?</P>
See if there might be a capacitor associated with the motor. If there is, I would suspect it. The online schematics are very skechy about the detailsof the motor. Capacitors are used to sometimes shift the phase for a starting winding...
I agree about the capacitor. The H-100 organs use a 3 micro-farad capacitor. I recently had to change one in my 1971 H-395. From the back of the organ, locate the light green motor to your left, at the end of the tone generator. The capacitor is a silver oval-shaped cannister, about 3" tall, with six wires coming out of it mounted just in front of the motor. An electric motor service business in your area (one that rebuilds motors) should have a replacement capacitor, or you might try an appliance repair parts store. The replacement will probably have only three wires, but it will work. If you feel confident in attempting this fairly simple repair, post back and we can talk you through it.</P>
One caution, the cap is NOT a Radio Shacktype of capacitor. They are designed for motor starting and are rated for AC voltage. For that application will probably be rated at 330 VAC. The othe responder mentioned 3 MFD which sounds right. </P>
This is a 3 MFD motor run capacitor. You may have to cobble the wiring. Suggest you get some Faston wire connectors and make an adapter cable leaving the original wires as original.</P>
