I've got a Maytag wall oven, 120 volt, model CWE4800ACB, about 11 years old. It's a good oven but I found out that when it's locked down for the self-cleaning, the heating element self destructs if there is so much as a crumb of grease on it or drops
on it while it's in the cleaning mode (if it was already clean I wouldn't be cleaning it ;-)
But I'd think twice about Maytag. I used to swear by them but since they got bought up a few years ago, their stuff is junk. I just had to replace a 13 month old Maytag fridge. It went through two ice-maker circuit boards and two compressors during that time. And they don't do their own warranty service anymore. They sub it out to a company that doesn't stock parts. It takes a week for the service guy to come out and look at it, then another week for the parts to come in from the central warehouse in Chicago. That was a total of 4 weeks without a fridge and about $500 of ruined food.
Google the model number to see if their are rants on it out there. I founds lots on the circuit board, but too late; I had already bought the dang thing.
