Describe your MER6770 Gemini Electric Kitchen Range Problem: Hi, our double oven Maytag Gemini model MER6770 (10 years old) just went cray last week. I beeps all time, most of the buttons and numbers do not work (press them, nothing happens). However, all four stove top burners still work. Does this seem like the control board should be replaced?

SOURCE: Maytag Gemini Electric stove fault code F 1-2 when using the oven(s)

The oven temp sensor has gone bad.  F1-2 would be for the lower oven and F1-1 would mean the upper oven.  If you give me the model # from the sticker on the oven I can direct you to a diagram, part #, and price.  These are very easy to replace.  Should be located inside the oven in the upper right or left hand side.  It looks like a silver rod about 4-8 inches long and crimped on the end.  Most of them can be removed from inside the oven by removing the two screws, pull out the sensor (harness and all) plug in the new sensor, put the screws back in and your done.  Some have to be removed from the back of the oven by removing the lower, larger back panel and follow the same process as mentioned above.  Hope this helps.

Put in a new thermastat in the top oven and it works great. Thanks for the advice(from other's having problems).
My Maytag was older than I thought, so the thermastat was not available on line, but found one at a repair shop that worked. Thanks!

Remember to turn the control knob past the "LITE" setting once the burner fires.
If that is not the issue you have one or more defective spark switches.
Each valve has its own switch wired in series with the others.
