Hello, our Whirlpool double wall oven recently started to beep and the entire display would flash on and off. First time hitting upper/lower off and start made it stop for several hours. After that turned breaker off for 2 mins and switched it back on. It displayed the normal PF (power fail) so I reset the clock and it behaved itself for a week. Today it started beeping and flashing again and nothing will make it stop. No pad sequences or resetting of the breaker. There is no specific error code (maybe I need to hit some key to display error code?) just every word/symbol on the display all come on at once, then off. Repeats and beeps every 1-2 seconds. Pulled the control panel and verified all connections good. The control board has been replaced twice in last 10 years (once when keys would not beep and another when timer would not alert when done) but have never seen it do this. And of course it starts acting up when the extended warranty ends. Murphys Law.
Excellent site by the way. Appreciate any information/clues/hints/tips you can provide.
