Oven light and display work but oven will not start heating; no error code.

Safety first: Disconnect power at the breaker before testing continuity or removing panels.

• Check for self-clean lock: Ensure the oven is not in a locked or self-clean mode that prevents heating.
• Inspect thermal devices: Locate any inline thermal fuse or high-limit thermostat on the rear of the oven cavity. Test for continuity; replace any open thermal fuse or high-limit thermostat.
• Terminal block: Verify that all three power connections (L1, L2, N) are tight and not burned.
• Control output: If comfortable with live testing, check for 240 VAC at the bake element terminals when a bake cycle is commanded. If no voltage and safeties are good, replace the electronic oven control board.
