A nice bright display again! Total cost: $0.44 plus a few cents in gas to drive to my local electronics parts place. I replaced the caps as recommended on my Jenn-Air oven and Voila!

This is likely a bad solder joint or connection... I had a intermittently dim display clock on a JennAir W256B. I recapped the ERC board (Y04100264) with high temp capacitors (found some 135 C caps!) but the problem wasn't fixed. I tracked it down to a bad solder joint on the transformer/relay board (Y04100260) in the back of the oven. The transformer on this oven provides 21 VAC and 4 VAC to the ERC board. Resistance of the 4 VAC was about 1.1 and the 21 VAC was about 5.0. Flexing the board and the 4 VAC would open circuit. I refluxed all the solder joints on the board and the oven now works properly, with beefier capacitors! As you state, the heat working on the capacitors will eventually get them to dry out and fail. Likewise, after 20 years of use, the solder develops micro-fractures and fails. Repair cost was still $10. ;^) If banging on the oven gets the display to come back, it is likely not the capacitors!
