I have a Viking double wall oven model DEDO130. I have terrible baking results in the upper and lower. Mostly burning the tops (pizza, biscuits, etc) while the centers aren't done. A tech from the place i bought it came out. Set the 400 the preheat went to 465 and then dropped to 350. The 5 subsequent cycles all yielded highs around 440 and lows around 360...an average 80 degree swing. I feel like the amount of direct heat to go from 360 to 440 is causing my tops to burn. The tech said to replace the thermostats would be around $325 and he couldn't make any assurances that the range would tighten up any. Any advise would be appreciated.

If you're running a double wall oven as displayed here, you would need to replace the control panel in the front that has the green little ribbon cable on it to solve this problem, I actually imagine that that part unfortunately may not be available anymore, however you could call parts and check availability at 1800 626 2000 This is also known as the keypad assembly.

good rule of thumb when it comes to food, "when it doubt, throw it out." it is not worth risking illness and other possible issues. my personal opinion.

Most double wall ovens are technically two separate oven boxes. The lower oven box has its bake, boil elements, high limit thermostat and ofcourse its own oven sensor. If the lower oven box boil is working good and less heat on bake feature may suggest that the bake element is burned out and only getting preheated with boil element. Just a suggestion here

Have you checked the heating element supply voltage with a VOM? And have you checked for a popped/burned fuse to the bake element?

The control panel face can be ordered from Viking Range unless the unit is very old, then I would suggest partstown.com, You will need the model and serial number from the rating plate on the unit. These parts are usually not very expensive and are really easy to replace.
Hope this helps....GOD BLESS...Randy...

To Set a Cook T ime:
1. On double oven models only, press UPPER OVEN or LOWER
OVEN for the one you want to set.
2. Press BAKE or CONVECT UPPER (on some models).
Press the number pads to enter a temperature other than the
one displayed.
3. Press COOK TIME.
4. Press the HR and MIN "up" or "down" arrow pads to enter
the length of time to cook.
5. Press START/ENTER.
The start time and stop time countdown will appear on the
oven display.
On double oven models only, when both upper and lower
ovens are being used at the same time, touch UPPER OVEN
or LOWER OVEN to display the respective cook time.
When the stop time is reached, the oven will shut off
automatically and "End" will appear on the oven display.
If enabled, end-of-cycle tones will sound, then reminder
tones will sound every minute.
Repeat the process by choosing the other option of UPPER or LOWER OVEN

i just moved and our stove in the new place doesnt bake things right. it seems that the top coil doesnt come on. its very difficult to bake anything. seems to come up to temp for pre heating, but only the bottom coil comes on. If you put it on broil, then the top coil gets hot. that works fine. tired of burning pizzas and biscuits. can anyone help with a cheap fix? dont have alot of cash.

I have a 2yo Kitchenaid oven, and my advice is first, don't use convection for cakes or pizza. Use the thermal oven. For pizza preheat to 500 degrees, then put the pizza on the lowest rack, and bake for 7-8 minutes.This way the bottom browns, and the top doesn't get broiled from the top element coming on during the bake cycle.

As for cakes, again place them on the low rack so that they get bottom heat. I keep my eye on the oven and when the broil element comes on I stick a piece of foil over the cake until it goes off. Otherwise it will set the top and the cake won't rise as much. Even doing that cakes don't rise as much as they did in my old oven, and they brown too much on top.

The convection oven does a good job of cookies, and the broil mode is okay.

I wish I hadn't bought this oven, but I didn't know about the upper (broil) element coming on during the bake cycle until I'd had it for awhile, and it was too late to return it.

If anyone's shopping for an oven, ask questions, and don't get one that maintains the oven temperature by activating the broil element when baking.

I had the same problem with a Wolf L-Series double wall oven (Model DO30) and called for service (under extended warranty contract). The tech told me that the F1 error is a latch problem (you know the one that grabs and locks the door during self-clean cycles). He cleared the error using a series of "secret" button presses on the control panel and the problem cleared. Now, when it happens (which isn't very frequently), I do the same thing he did ... press "0" and "Temperature" for the oven causing the problem and hold them for about 5 seconds. The oven will ding and the display will show some diagnostics, including the error event. Press "Cook Time" and "Stop Time" while in this diagnostic mode to clear the error register, then press "Off". I've also tried to keep the area across the top of the oven opening clean (with a little degreaser), especially around the latch, and I've sprayed a bit of WD-40 into the latch periodically for lubrication and cleaning.

The control switch may be bad on it. If there are 2 elements on the top, they both are not bad at the same time.Check to see if the wires have not burned off the control switch first. Check to see if your breakers are O.K. Turn them both(maybe 3) off and then reset.
