Hi, I have an IKEA Whirlpool oven. Last night, I was timing something. When the timer went off, I pressed the "Cancel" button. Normally, the timer would cancel in this circumstance. However, this time, all the lights went off on the oven, and all the buttons have been disabled (i.e., Bake, Broil, etc.). The burners on the top of the stove still work, and the lightswitch still works. It's just all the buttons related to the oven do not work. Can you please help?
