I too bought a stove (Maytag) with the infamous 7403P331-60 membrane keypad which goes bad every year or two (starts beeping with the F1 error code). I bought my stove in 1994 and have replaced the keypad about eight or nine times.
Maytag customer service was totally in denial that this is a part which is poorly designed (either by incompetence or on purpose). Remember those commercials with the bored Maytag repair man? What a joke. At least I watched how the repair was done and have done all replacements of this part by myself.
One thing is for sure I will never buy another Maytag appliance on principle and if possible I will avoid electronic controls on my next stove. Oh, if you think you can stop the annoying beeping by disabling the beeper- good luck it is not in the appliance diagrams.
I think it is built into the clock module.
