The timer on my ml600tw will not run. I do not hear it working although I have power and can trip the lights on if I turn the clock. Can you tell me what the problem is? Howard

If the clock dial is not rotating, the clock motor has gone bad.
Easiest solution is set power pack in override so lights are on, then plug power pack into cheap plug-in timer.
Some people report being able to disassemble clock motor and add vaseline to gears to restore functionality. Other peole report not remembering how all the tiny gears fit back together.
My experience is that once motors slow down and overheat, they never work correctly again.

The small motor that runs the time clock is bad. If it stops the motor when it comes to the start and stop clips, it's done. Replace it.
