Oven update
Two repair companies came out and both said the ovens can't be repaired. It's likely that parts exist somewhere, but my parents in their 80s are not appliance hobbyists and their 1972 Hotpoint is not a collector's item. THey need something that works. Their first choice would be to have what they know (current range) repaired, but it can't be done easily and they need easy rather than a restoration project.
They'd like to replace it with a freestanding electric range with an over the range microwave---thus allowing them to give away their counter top microwave and free up some counter space. There are however some issues that go along with their request:
1. I don't trust my father re: setting the house on fire with burners he can't see (smooth top) so for safety we are looking at electric coils which he CAN see.
2. Oven needs to have KNOB control, not an electric control panel in back that they have trouble seeing/operating. Age 86 is not a good time to be forcing them to learn to operate something new, even if the world has since gone over to electronic controls.
3. Self clean preferred. Black or steel on black. A dual oven range would be nice (secondary oven in lieu of storage drawer) but to my knowledge these all require electronic oven controls rather than knobs, plus I couldn't find any models with coils, they're all smooth tops.
That said, I found several models among the GE, Frigidaire, and Whirlpool lines that have the above features. Also found over-the-range microwaves that would do the trick. That said, there are a few more issues:
4. We are not sure whether the existing range is hard-wired or whether there is a 1972-era 220V plug. If the former, they'll have to install an outlet. If the latter, it may have to be changed to 2014 configuration to accept a modern plug. We are resigned to the fact that this needs to be changed. The appliance store will do it for $100 if we purchase new range from them.
5. Here is the kicker: both upper and lower ovens worked off the 220V. We don't know whether there is also a 110V outlet behind the range. There are low wattage functions like lights and fan that likely run on 110V, but we're not sure whether there is a 110V outlet or whether internally the oven transforms the 220V power to 110V for use by the low-wattage applications. If it turns out there IS no 110V outlet and only a 220V, I"m guessing that an electrician could install a 110V when they rewire the 220V.
6. They have a tile backsplash that does NOT extend behind the range, it's just painted drywall. Assuming that the resulting bare wall above the new range and below the new microwave is an odd or irregular size, how hard is it to have a steel backsplash made? We know the space is 30" wide but don't yet know the height. Also, I think the tile may extend in behind the range an inch or so, so I won't know the exact width of the bare wall until the old range is removed.
7. Some of the microwave models I inspected on line had CFM ratings of 400. I was only aware of 200-300 CFM models. Does the extra 100 CFM make a difference in performance or is this just hype?
Thanks in advance for your guidance and suggestions. The appliance store they use has a reputation for restoring old appliances and possibly they may use it in their vintage showroom (Gormsen's Appliances, Pacific Beach, San Diego, CA).
One thing I just realized is that virtually no ovens now have electric clocks/timers. The microwave of course will have time display and a timer, but it'll take some time to train them how to use it and I know they'll miss their analog timer. [this post was last edited: 12/9/2014-09:41]
