this range beeps almost non stop. i say almost because sometimes it stops beeping for a short while then starts again. oven will not come on (bake,broil,clean,timecook,warming drawer-anything) you can hit clear and it will stop beeping for two or three seconds then starts right back screeching. you hit bake and tempset and it acts like its coming on display shows bake and 100 degrees then after three seconds it clears and just goes back to a flashing clock and no cooking but sometimes when it cuts off it flashes f11. retry the process and it will flash f14 or f18 or that same f11 before it cuts off. replaced the expensive erc control board/clock at a friends suggestion but nothing changed doing exactly what i described still. in desperate need of help before i go broke and crazy. thanks
