On the stove it says MayTag Gemini - on the receipt, I believe this is the model number: MER6875BCW (from the receipt).
That is the model number. IF you set the bottom of to 350 degrees, is 350 displayed in the control?
Yes it does. Then it goes to pre heat (100) and won't go past 220 or 230 degrees.
Do you see any white marks on the element, or burn marks?
The oven needs both broil and bake elements to heat the oven. The issue is either the broil element or th control board.
