Lovely kitchen!

Blue 39" AGA maybe? That oven is going to be hard to replace!

Does she need gas or electric? Here's the AJ Madison link to both. Ilve makes one, including a small oven, but it's duel fuel.
I wonder if looking for a vintage model would make more sense. Before a kitchen reno brought a reconfiguration, I also had a 40 inch range space.

We currently have the Kenmore version of the 40" Frigidaire and do almost all our cooking in the small oven. It has worked very well for us and the size of the small oven has not been an issue.

akrogirl, that's good to know. That is one that she is looking at. Did you have to buy special cookware to fit the small oven?

She needs an electric range.

My MIL has that 40" frigidaire. She regrets the choice as the small oven is too small for anything but a loaf pan. She uses the large oven instead. She was just telling me a couple of weeks ago that she wished she had realized the size issue before she purchased it. She's not TKO so didn't think to double check measurments.

Something vintage or at least non-modern looking would be cool in that space.

Be still my heart. Love her kitchen!

She should try to get it repaired.

OMG, I use to have that very stove. I loved it with all my heart. It was my DH's grandmothers originally. I use to love to fix turkey in one side and pies in the smaller side. If I were your Mom I would get it fixed if at all possible.

Terriks, I already had the Pyrex glassware, 9" x 11", and some similarly sized Chantal bakeware. They fit perfectly.

What an adorable kitchen. Did she look into getting it repaired? Looks (and sounds) like a great stove.

She has had several repairmen out, and it can't be repaired. Actually, it's just one element that isn't working, but she has a home warranty and they will replace the stove with the Frigidaire unit. She is worried that something else may go wrong in the future.

The kitchen is original to the house, which my grandparents built in the 40s. The stove is about 40 years old. I remember when my grandparents bought it. ;)
The tile in the picture is original, but she recently had it redone, and it looks exactly the same. She got a real craftsman to do the job.

What part of the world is she in? East, West, North, South? You need to find a vintage stove restorer.

I don't understand why it can't be repaired. I just found the following quote on such a website "We do a mechanical overhaul, looking at the pros and cons: the pro- the gas range can be rebuilt. The con- the electric range cannot be rebuilt, it has to be replaced. We replace the wiring, the element, clean stove and restore parts."

It's a confusing statement to me. Seems like it's saying it's possible and not possible at the same time.

Naively, perhaps, I can't imagine why the elements & wiring couldn't be updated. Odd coil sizes perhaps?

Last thing! I just found this electric stove part. Maybe what your mom needs?

Replacement coil burner elements usually easy and cheap to replace, especially if you don't care if the appearance doesn't exactly match the others. GE or Hotpoint use Calrod elements, nearly everything else uses the, er, non-Calrod. Older Frigidaire stoves (made by General Motors) use a very thick coil that's harder to find but they're out there.

"She has had several repairmen out, and it can't be repaired. "

You need a restorer or a repair man who is not just a 'parts swapper.'

There is nothing on that stove that cannot be repaired or replaced.

It is just very unlikely to be an OEM part.

Thanks for all your help. My mother has read the comments, and has decided to keep the stove for now. The only issue is the "Sensatemp" element, that has some sort of special features, but otherwise works fine. She felt that the smaller "small" oven in the replacement range would be more of a problem than not having all the features of this particular burner. And a more modern stove would not look as appropriate in the kitchen.

Have you googled the part that she needs? You just might be able to find it with the right search words.
