Range or wall oven shows LOC, Lock or a padlock and won't respond

Most of these calls are the Control Lock (child lock) feature, which disables the pads and on some models locks the door. It is released with a press-and-hold on a specific pad, and the key differs by brand and model. Some ovens also lock the panel automatically during self-clean, a probe cook or twin-cavity modes. Only if the lock will not release, or comes back after a power reset, is it a door-lock or control fault.

Food burns or over-browns on the bottom (foil, pans, rack position before the bake element or sensor)

Bottom burning is most often caused by how the oven is used: foil or a liner on the oven floor or covering a full rack, dark or thin pans, a rack too low, or skipped preheat. Rule those out and run a measured bake test before replacing an element, a sensor or a control. If the average temperature is off, calibrate it with the control's offset; only a sensor or control that cannot hold temperature is a part.

Oven cooling fan keeps running after the oven is off (or never runs)

Electric and many gas ranges and wall ovens have a cooling fan that protects the controls, door and cabinetry; it keeps running after the oven is off until the controls area cools, and cannot be switched off. Running for a while after a long or hot bake is normal; running with the oven cold, starting at power-up or never stopping points to a fan thermostat stuck closed, a welded relay, a bad temperature sensor reading or a control fault. A fan that never runs is a safety issue because the controls overheat.
