After reading problems with several ovens going dim with their LED display light, I came to this conclusion: pay ~$500 for a service visit and new display board :mad: or try replacing the capacitors (3) that are typically found on these boards :confused: . I have read posts that these things go out (lose their capacitance) and hence you start struggling to see the clock and oven temp.

I have a Thermador oven, 5 yrs old, and have zero experience repairing these things. Also, I have never soldered before and didn't know where to buy a "cap". But here's how I did it.

Took my oven apart (pulled out a trim piece), unscrewed 2 screws, and got to my display board. Unplugged 3 cables attached to this board. Took my board to Radio Shack. Picked up solder and "solder braid." Apparently, all the high school kids have been buying all these CAPS
and RS didn't have the ones I was looking for.

My board had 3 CAPS. I read a helpful post online stating try and get the same uF (measure of capacitance) on the CAP, same or slightly higher operating voltage, and a "high temp" CAP. All of the details should be printed on your CAP that you are replacing. So again, just used that as a starting point.

I called around town and found 3 places that sold CAPS. None had all of the ones I was looking for and none had CAPS rated for a higher 125C temp. I needed to replace two 470uF at 35V (105C) and one 68uF at 35 V (also rated at 105C).

I got the 3 replacement CAPS (2- 470uF at 35 V) and (1-68uF at 68V at 85C). I used solder braid which sucked up the solder that allowed me to pull the old CAPS out. I then used a thin diameter solder to set mine in the board. My 68uF CAP was slightly bigger than the old one, but it fit.

I plugged it in, put things back together, and flipped the breaker back on. Voila.....success! Just like new with a bright display. I'll probably have to do this again in 4-5 yrs, but at least I am not paying $500 for a part that will do this same thing again. All in all, I spent about $25 (would have spend only $7 if I had the solder stuff already) and about 3 hrs (much of it driving around).

Give it a try. If you don't have experience like me, the worst thing is you get a new board or place a service call. If you are having this problem, just might save you a lot of $$. Good luck. :) BTW - please read these 2 helpful posts. This is what I followed.

Ok, I am a "do it yourselfer" only in my mind, I am occasionally successful, usually make a bigger mess. Anyway, I have a thermador double oven that the display has gone dark, and I don't want to pay $500.00 to fix it, so I searched for answers and found this site. I was very excited to learn about replacing the capacitors as a fairly easy fix. I took off the cover of the touch pad panel and unplugged the long white (approx 1 1/2") bar and the small (square w/ 4 prongs) plugs w/ wires. Then I took the small display board to the electronics place to order the capacitors.

When I took the display board off the first time, I didn't unplug the big cover panel, and when I put it back together, the oven still worked. This time it didn't. I don't know if I might have plugged the little black plug w/ 4 prongs on backwards and if that may have blown in internal fuse...

I am just wondering if I broke the whole thing. Does anybody have a suggestion or should I just call a repair person? I would appreciate any suggestions - Thank you!

Thanks to all the successful DIYers on this forum who fixed their Thermadore oven display, I decided to do the same.

The 3 caps mentioned 2x 470 and 1x 68uF are the ones I replaced and, voila, the display is now functional.

Mine is a double oven, SCD302 (though the control system seems to be the same across the line).

It was an uneventful replacement. Unlike other boards described in this thread, mine had 2 caps well accessible, whie the 3rd (a 470) was obscured by the display which folds over the board. Initially, it appeared touch to pry open, but it gave with a little pressure. There is a rubbery rectangle in the middle that bonded the display to the back of the board (it was a bit of a mystery why the display would not bend away until I saw this).

Parts--I got them from Digikey, and I could only find 105C rated caps. I did not even bother with the local Frys or RS. A local South Bay (SF) component store call Anchor did not carry the high temp version--85C is the standard rating.

Definitely seems to be a common problem with the Thermadores. Thanks again to the contributors here.

Greetings all.....glad several others have gone the DIY route and also fixed their oven displays. I posted this a few years ago and came across this site again given I had bookmarked it back in '09 for future reference. I am sure I will be doing ths again. Fortunately, I'm on my 2nd year and our display still works fine.

What I have not heard is why these oven displays dim over time. I assume the heat that goes up to these boards slowly degrades the CAPS? Who knows....just glad this has been fixed for several of us.

Cheers...
