Kacie S Cullman , AL October 10, 2016 F1 error code when we turned the oven off and back on (per suggestions online) it appeared to work but then it wouldn't heat up We ordered the controller (per some different online suggestions). It was VERY easy to install. You basically just unscrew the outer panel, then unscrew the controller, unplug 6 or 7 wires and plug them into the new controller. Worked perfectly after that! 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
