Further adventures later.

I did get a Wolf countertop on sale because nothing else regulated temp well enough. Problem is the 12 inch depth, which rules out some cookware.

Still haven't figured out its timer!!! Nor the probe. Reading the manual again to find out if it/they just indicate or actually shut off the oven. Works OK without them.

I will need a range for the foreseeable future, still roast and bake a lot. I don't know what a Wolf is, but I'm going to look

EDIT: I checked the Wolf countertop oven. Not sure I have the room, but it's sure an idea Thanks!

Way overpriced unless on a big sale.

I am fit for my age but a klutz with anything low like a regular oven. People will suggest Breville but I had one that quit a day after the warranty expired and I could not navigate the insides to replace a 20 cent inline fuse.

Others have had better luck.

Stuff is too complex. I had a big Rival that fit a popover pan easily but it never broke 350 degrees.

The Wolf has a hard limit of 12 by 15. Most pizza pans and stones are 13 inches. So a 12 inch cast iron has to do. Popover pans fit but I have not mastered popovers. Being half a mile high might have something to do with this.

Many "9 by 13" baking pans exceed 15 inches with their grips. I measure.

So, it's not all peaches and cream. There's always the big oven but it's gas and harder to clean.

Even with all of the modern conveniences, getting the food from market to table is still tricky. I baked a few things in Colorado years ago. It was easier for me to bake than it was for my body to get used to the altitude. I wasn't there long enough. S.W. near Durango.

But recipes are adjusted only for a whole mile up, it seems.

Good luck.

Control circuit errors can be caused by power line transients or brown-outs, so you need to insure this error repeats before undertaking repairs. You might even have a faulty connection in the power feed to the range.

Questions:
Does the range seem to be working OK now?
Have you noticed any irregularities with your power service such as digital clocks that reset or lighting that blinks?
When the range sat unused for 18 months, did it have electrical power applied?

If you do wind up taking the control panel apart, I would suggest checking all the connectors between assemblies in case one has vibrated loose (with power off for safety, of course). You might also want to carefully inspect the circuit boards for bad solder joints.

Should you decide to replace a circuit board or sub-assembly, be extremely careful when ordering because manufacturers make many revisions to circuits during the life cycle of products.

Good luck!

This was the first time. I used the stovetop twice since the incident and turned on the oven once, just for a few minutes. I didn't notice the power failing. If I end up making any repairs, I'll get an appliance tech or electrician to do the work. About all I'm up for is switching the circuit breaker on and off
Thanks again!
