F1-1 F2-3 and F1-2Errors

We have a Maytag Gemini Double Oven we purchased in 2000. We started getting an error on the bottom oven and after a little while also getting it on the top oven. The oven will kick on then kick off not getting up to the desired temp.

F1-1 and F1-2 are the tow main errors which from searching appears to be a defective membrane switch. I read the switch resistance can be tested but not sure where it is located.

Does anyone have some documents schematics on this model? I am not even sure if the parts are even available for this model anymore but figured I’d check before making a new purchase.

Is there a manual available?
