    Default Thermador Dim Temperature Display

    I have a Thermador SC302t double oven in Stainless Steel that I believe is likely from the late 1990's. We purchased it second hand from Habitat For Humanity's store called, "ReStore". Unfortunately the temperature display is so dim it is no longer visable and the clock display is somewhat light but we can still see that. The ovens work beautifully, it's just that we're flying blind while using it. After doing some research, I quickly found out that this is a very common problem with this oven and simply involves changing out 1 to 3 of the display capacitors on the display board. Great. Sounds easy enough, however, most everyone is stating that their display board contains two 470uF 35volt capacitors and one 68uF 35volt capacitor. Mine appears to have the same two 470's, however the spot shown for the 68uF capacitor is a 220uF in mine. This seems odd to me. Since I am not the original owner of this double oven, I have no way of knowing if Thermador asked them to change it to this at some point, the whole board was replaced and this is what came on it, or the previous owner took it upon him/herself to use a much higher capacitance (not usually a good idea from what I hear). I have seen people replace this 68uF to a 100uF because they could not find a 68, and that might be okay, but a 220? I'm not sure about that.

    I am mechanically and technically inclined, however, I am illiterate when it comes to this sort of stuff and really know very little in the area of capacitors. I need suggestion on what I might replace this 220uF capacitor of mine with. I'm tempted to get as close to the original 68uF that I SUSPECT this oven came with, but I don't know. Any thoughts would be appreciated.

    Hi,

    Many brands and style has an issue like this

    I have no way of knowing if Thermador asked them to change it to this at some point, the whole board was replaced and this is what came on it
    Thermador just bought the clocks/control from a vendor. When this issue occurred there where clock kits available to replace the clock/control...but these are NLA now.

    You would likely be better off to remove the clock/control and send it away to be rebuilt...

    Hey Jeff, thanks so much for your input. Yeah, the dim temp display was apparently a super common problem on this oven due to the heat rising from the oven and the capacitors overheating... or something like that. Fortunately there will be no need to send off the clock/control board to be rebuilt because many before me have shown how to successfully de-solder the bad capacitors and then solder in new ones. Super cheap and simple fix, so no worries there. I'm just baffled by the odd and unusual capacitance on the one capacitor in my oven, which is why I am seeking advice here. I suspect that it is very likely these capacitors have been changed numerous times, as most have said they usually blow out within a couple of years, and I believe this oven is from 1998-ish. So, the likelihood that the previous oven owner had this capacitor changed at some point before is high. I'm thinking that maybe they put in this high capacitance as a replacement thinking this would be okay, but I am just not sure.... So, here I am asking questions

    I just want to touch on liability.
    I have seen some do repairs to boards, clocks, etc and some are great and some are not......have even seen a few fires from such repairs.
    I will no longer take on the liability of doing such a repair and let the clock repair companies do this for me....then *if* something ever happened the liability is not mine.
    No one hopes for an issue, but you never know.
    Sorry can't help with the specific info on the components of the clock.
