Oven does not heat at all; no error code displayed, lights and display work normally.

Safety first: Turn off power at the breaker before removing any covers or testing components.

• Check terminal block voltage: At the rear terminal block, verify that full supply voltage is present (e.g., 230–240 V). Loose or burnt connections must be tightened or replaced.
• Inspect high-limit fuse: Locate the thermal fuse or high-limit thermostat on top of the oven cavity. Test for continuity; if open, replace it and investigate cooling issues that may have caused it to trip.
• Test bake and broil elements: Measure resistance of both elements. Replace any that are open.
• Evaluate main control board: If power, fuse, and elements are good but no voltage is sent to the elements in any mode, the main control board is likely defective and should be replaced.
