Oven is 16 years old; repaired control board several years ago. Within the last 2 weeks our neighborhood had a power outage for 6 hours. This issue with the oven didn't start until after this incident; don't know if its related or not.Oven will beeps randomly for several seconds and will do this intermittently. I have silenced the sounds on the touchpad and have turned off the breaker to the oven for several hours; beeping continues. Is this a control board issue again or is the touch pad itself going out?
