When our power went out for about 20 mins & came back on our Maytag stove started beeping and the touchpad display is all gibberish..words, numbers letters etc and none of the buttons willwork. The burners turn on but the touch d seems stuck how do we fix?

new ovens and electronics have error codes programmed in, my new stove does, you need to call an electrician and tell them the exact beeping issue and this will give them an idea on what may be wrong. In the meantime see if the manual it came with has a trouble shooting or error code page, or go to http://www.maytag.com/webapp/wcs/stores/servlet/OCManualsLiteratureSearchResultView?catalogId=10562&langId=-1&storeId=10212

sounds like a door lock switch going bonkers? seen it b4

e-mail the manufactor or call the company.

try to unplug the oven and let it sit for a bit then plug it back in.

Buy a new stove element. If you open the stove look in the back. It should be black. It might have a crack or be clearly broken. This is a cheap fix. If you want to be sure that it is working at the connection unplug the element and pull it out. Put a volt meter into the prongs. Turn stove on and see if its putting out voltage.

Replace the electronic control.

there is a short for sure, sometimes when the heating element burns out and melts, it touches the metal inside the housing causing a short. inspect the heating elements in the oven(top and bottom). the loud buzzing sound is what a shorting out heating element makes as it melts like a weldin rod, usually because of using tin foil(not recommended)

Hold your finger or thumb on the red light for a few seconds, and you will hear three beeps. This tells you that the lock is off. If the light is not on, do the same and there will be three beeps, and the light will come on, telling you that the lock is back on.

I have a Stoves 900 CTH with the same problem. Its been like it for about 6 months and we're still able to get it going eventually.
If you turn the power on at the mains and leave it beeping for about 2 hrs then press the power on touch button. You should see all the "0."s flashing. When the flashing and beeping goes slow try pressing one of the hob buttons alot until the little dot illuminates next to the 0 then quickly lit the + button.
It sometimes works after 5 mins but other times it takes 20-30mins and is a real pain in the ****.
I did ring Stoves a while back and they quoted me £190 for the pcb but I hardly use it so just lived with it as it is but I finally had enough tonight and done a web search which turned up this thread.
I've just pulled it to bits to see if I could locate this "C17" but not 100% sure what I'm looking for.
Is it the big silver thing in the center with 5B RVJ on it?
