Have you been using the oven? Were you happy with it? I have one with the rotating panel -- mine is a double oven and I suspect would run north of $5000 to replace and is in very good shape, so I would probably repair mine. Once the control panel is replaced, the mechanical parts should keep going for some time. If your oven is a single and/or the it is seeming to show its age (fit or finish worn, hinges not strong, door seal not tight, etc), the cost/benefit may not be as good for you.

In comparing repair to replacement costs, include any costs involved in revising the wood cabinetry to fit the replacement oven. This could vary greatly (or be zero) depending on the cabinet material and the type of revision needed. Also repair might take an hour, while in a replacement process, the new oven might not be usable until the carpentry was completed.

Ours is a single. We used it often, but it has been broken for a few months now, so we have been using the oven in our gas range in its place. We preferred the wall oven until it broke. The panel started to beep and flash continuously so we had to shut it off at the breaker. We have been trying to decide what to do. It seems to be in ok condition other than the electronics, though we can't actually evaluate it at this point because it can't be used. A new Kitchenaid would be about $1900 (on sale) and we were told that it would fit in the same opening. Not in the same class as the Wolf, but we aren't sure what we would be giving up if we stepped down. We've also been shown options from Jenn Air and DCS.

Since it sounds like you were happy with the oven before it broke I would repair it once and take the gamble that you'll get another 10 years out of it. I would replace the next time a similarly large repair bill came along. I would not take the word of an appliance store that a new oven would easily fit into existing cabinetry unless they have come out and taken precise measurements.

I think I would be similarly inclined -- give it one repair and you may get another 10 years or so -- good value if so (the KA oven may give you 5-7-10 - you don't now there either), but I probably wouldn't do another major repair.

Ditto on the cutout -- chances are they are not exactly the same, especially if different makers. Check the measurements. Width is fairly standard, but not exact. Heights vary more.

You should consider once the new panel is in that whenever feasible keep the door to the oven closed when it is hot, and in particular, do not broil with the door ajar. Heat is the killer of electronics. I expect the if you choose to repair the panel, the repairman will check that the cooling fan is operating and not gunked up.
