Oven door locked after power outage - Kitchen Ranges

Usually, on electronic oven controls, the user must clear the "PF" error or other such similar condition first. Next, look for a set of buttons with "lock" below them or a "key" symbol. You would then press and hold both buttons for 3-4 seconds until the lock light goes out, or a message will show "disable". I don't know what model range you have so I am giving options that I have seen in the field. On some ovens, just a single button is pressed and held--some models have a separate "cooktop lockout" and an "oven lockout". This prevents children from either activating or changing settings when un-supervised. However, the power outage may have *damaged the electronic oven control* by hitting it with a current surge when the power was restored. THIS IS COMMON and why I always encourage my customers to purchase a "whole house surge protector" for between 60 and 100.00. It is some of the best money you can spend to protect your house--current surges aren't covered by warranties or most protection agreements.
