Default Dim Clock LCD on Jenn-Air wall oven

I actually fixed this bugger a while ago, but though it would document it now so someone else with the same problem might be able to Google this and save some $. I have a Jenn-Air electric wall oven with all digital controls. At some point the VFD display module began to get dim to the point it was unreadable. Some times it would come back to life but eventually faded out completely. After much teeth gnashing I determined the problem to be a bad capacitor. C3, a 68uf 35v was bad. It has been about 2 years now since replacing this capacitor and the clock is still going strong.

The clock module has the following numbers on it: 100-00695-20 CN 7601P483-60. The Maytag part number is 71001799. The part costs around $170. It may also be used on other Maytag made brands (Maytag, KitchenAid, Amana, Magic Chef, Kenmore, Whirlpool, etc).

The capacitor needed (C3) is a 68uf 35v, 105C, low esr cap. I recommend Panasonic FC series (Digikey p/n P10292-ND) capacitor, but any other brand that is good quality, low esr and rated for 105C will work. After removing the cap, clean up any electrolyte that may have leaked out of the bottom with a q-tip and alcohol. If your clock has a different value in C3, be sure to replace it with the same value as what was removed.

If you order from Digikey, the cost is $0.31 as of 6/2018. They do not have a minimum order at this time. Be sure to choose first class mail as the shipping method and the total cost will be around $8. I would recommend purchasing from, but TC does not stock a cap of this value.

It is usually not required to replace the other capacitors as described in some of the other posts in this thread. Try replacing C3 first to see if it solves the problem before attempting to replace any of the other caps.

Some people have reported finding a resistor being attached inline with C3 in what appears to be refurbished clock modules. These modules may have an 'R' at the end of the part number on the sticker. See picture here:

If your board has this resistor along with C3, it is safe to remove it and just replace C3 with a 68uf 35v cap as outlined above.
