Diagnosis
The bake element has likely failed. This is a common failure point. The controls will function, but the primary heating component is open.
How to Fix It
Visually inspect the bake element at the bottom of the oven cavity. Look for any visible cracks, blisters, or breaks in the metal coil. A multimeter continuity test confirms failure.
If That Didn't Work
Check the oven's thermal fuse, located near the broiler compartment. A blown fuse will interrupt power to all heating elements. This requires continuity testing.
Heads Up
Always disconnect power at the circuit breaker before attempting any internal inspection or part replacement for safety.
