What was on the plate when the rollers melted??
Some things, especially meats that have grease but little or no water
will get very hot.
It could have over heated the container and then the plate and then
the cheapie plastic rollers would be next.
I can only guess you're getting the model number wrong some how.
Maybe a zero is actually an Oh or something like that.
A capital (eye) can look like a (one).
Take a close up photo of the model number plate and post it here or
send it to the tech support for Magic Chef. I bet they'll figure it out.
