Found this forum because we've never seen the Telechron timer on our Wedgewood stove work. I replaced the wire but that didn't do the trick. It looks like there's some damage to the coil, but otherwise I'm at a loss. Looking for some help to point me in the right direction!

Separate the motor from the clock, power it up and confirm it's getting 120 VAC. (be very careful working with 120VAC or take it to a clock repairman). If the rotor's pinion gear does not turn at 3.6 RPM, then test the coil for around 600 ohms + or -. If the coil tests good and is energized then you likely have an H-3 rotor well past it's useful life (most common issue). I can provide a replacement here:

If your coil tests good, then you should reinforce the outer paper wrapping with 3M #27 Glass Cloth tape. That old loose insulation paper does not have much strength left and if those solder terminals break off from the tiny magnet wire going to the core of the coil then you'll likely have to replace the coil which I can also provide.

I'd also suggest giving that movement a good cleaning. Kitchen clocks are susceptible to a build up of dirt/grease.

If the motor runs only when separated from the clock then you likely have problems with the movement.

I agree. Most commonly in these clocks the rotor stops for lack of lubrication (a whole long story).
