Electric oven will not heat on bake or takes excessively long to preheat.

Safety first: Turn off power at the breaker before removing any panels or touching elements.

• Inspect bake element: Look inside the oven for visible breaks, blisters, or burn marks on the lower bake element.
• Test continuity: Disconnect the element leads (from rear or front access) and measure resistance. An open circuit indicates a failed element.
• Check wiring: Inspect wires at the element terminals for signs of burning or loose connections. Repair or replace damaged wires and terminals.
• Verify power: Confirm the range is receiving full 240 VAC. A missing leg can cause no or weak heating.
• Replace element: Install a new bake heating element if it is open or damaged.
