Oven will not heat in any mode; display is on, fans may run, but temperature never rises.

Safety first: Disconnect the oven from power at the breaker before removing any panels or testing components. High voltages are present even when the oven is off.

• Check for obvious element damage: Open the oven door and visually inspect the lower bake element and upper broil element for blisters, cracks, or burn-through. If either is visibly damaged, it must be replaced.
• Test continuity of heating elements: Remove the rear panel (for built-in models, pull the oven out carefully). Disconnect the wires from the bake and broil elements. Use a multimeter on the ohms setting; a typical 240 V element should read between 15–40 Ω. If the meter reads OL (open), replace the failed element.
• Check the oven temperature sensor (NTC probe): Locate the sensor inside the cavity (usually at the upper rear). From the rear of the oven, disconnect its connector and measure resistance; at room temperature it should be around 1000–1100 Ω. If it is open, shorted, or far out of range, replace the sensor.
• Inspect wiring and connectors: Look for burnt spade terminals or melted harnesses between the elements, sensor, and main control board. Repair or replace damaged wiring using high-temperature rated wire.
• Evaluate the main control board: If elements and sensor test good but no voltage is sent to the elements when a heating mode is selected, the relay on the main PCB may have failed. Replacement of the control board is typically required.
