Digital display on front panel - lights are dim to unreadable. We have no idea how to proceed, but need to do so that we can read the temperature of the oven. Thanks, Jami
I have the same problem with mine. Do you know what the approximate cost for the repair is?
Mine had the same problem. Got a replacement display unit from the local appliance store's parts dept for around $125. Installed it myself, problem solved... for now.

Fade
Fading is sometimes a problem with VFD displays. Light output drops
over time due to falling emission and reduction of phosphor efficiency.
How quickly and how far this falls depends on the construction and
operation of the VFD. In some equipment, loss of VFD output can render
the equipment inoperable.
Emission may usually be restored by raising filament power.
Thirty-three percent voltage boost can rectify moderate fade, and 66%
boost severe fade. This can make the filaments visible in use, though
the usual green-blue VFD filter helps reduce any such red or orange
light from the filament.

You first need to identify whether it is the display itself which is at
fault, or the circuitry which drives it. Dim displays fall, I would say,
roughly 50 / 50 into low drive volts, and worn out. Often, the drive volts are derived from a voltage multiplier, and it is very common for the input capacitor to dry out and go low value, which leads to a low supply. This is typically about -30v DC when correct. The filament supply, which you can normally measure at about 1.5 to 3v AC, is usually floated on top of the -30v, so that is a good place to measure it. Most VFDs have a pair of pins at either end of the main row. Measure across these to check the AC filament supply, and from either one or the other to ground, to measure the negative supply. If these are all in order, then the display is worn out. Often, when it is worn out, there will be patches that are brighter than the rest. You may be able to squeeze a bit more life out of it by boosting the filament supply a tad, but if you go too far, the filament wires start to glow a little, and may become visible.
The VFD (Vacuum fluorescent display) will need to be changed, this means that the control clock will have to be changed unless you can find a local company to re-build it.

This is the second time this has happened to ours. The first was replaced under warranty and the second is one is now out and 3 years old. To bad these nice ovens have a re-occuring (expensive) problem to fix.
Have the same problem with our double over by DCS -- Purchased in 2004 -- The display is getting lighter and hard to read
The Digital display on the front panel - lights are now dim to unreadable. We have no idea how to proceed, but need to do so that we can read the temperature of the oven.
Having the same issue. Purchased oven in 2002 - must be the 7 year itch??
I am having the same problem with my DCS oven display. The oven is a little over three years old, and the display has just became unreadable. I find it hard to believe that a quality appliance would hevae this issue. I have a cheap mircowave and toaster oven whose display are still going strong.
Has anyone contacted DCS to see if they will back up their product?
