If you own a Hammond organ that does not work properly the problem will need to be correctred.This will require you to first determine how to start the organ to see if will turn on. You can then test the organ to see what does and does not work on the machine, to determine what will need to be fixed.

Step 4: Release the Start switch and wait while the tubes in the organ warm up before hearing any sound.

Step 3: Examine the end plate on the Tone Generator and see if it is bent. Gently bend the end plate back into the correct position so that it will engage the Start Motor.

Step 4: Observe the gear on the shaft of the Tone Generator and see if it is dry or has residue built up that prevents it from sliding freely. Apply lubrication spray to the gear and work the gear until it will slide easily.
