My human thought she turned the oven on, but it didn't heat up. She assumed she set the temperature but forgot to actually turn it on until it happened again. The internet recommended a new bake element, but it stayed cold.
After more troubleshooting and colorful language, a new control board was installed. The connections on the replacement part didn't match exactly, so they turned on the power while aiming an extinguisher. It worked and nothing caught on fire!
