Oven preheat takes excessively long or never indicates preheat complete

Safety first: Turn off power before inspecting elements or wiring.

• Step 1 – Verify power: Have an electrician confirm that the oven is supplied with the correct voltage (typically 240 V). Lower voltage will increase preheat time.
• Step 2 – Check elements: Inspect bake and broil elements for hot spots or dark areas during heating (view through window). Replace any element that does not glow evenly.
• Step 3 – Door seal: Inspect the door gasket and hinges for proper sealing. Replace worn gaskets.
• Step 4 – Convection fan: In convection preheat, ensure the fan runs. If not, see convection fan fault procedures.

Note: Large, heavy cookware and frequent door opening will also extend preheat times.
