F76 error; oven may not start or may shut down during operation

Safety first: Turn off power at the breaker. Do not attempt to bypass relays or safety devices.

• Visual inspection: Remove the rear cover to access the main control board. Look for burned spots, cracked solder joints, or melted relay housings.
• Check incoming power: Verify that proper line voltage is present at the oven's terminal block. If power is missing on one leg, the issue may be at the house wiring or breaker, not the oven.
• Element continuity: Test bake and broil elements for shorts to ground. A shorted element can damage control relays. Replace any element that shows continuity to chassis.
• Replace control board: If F76 is present and visual/electrical checks indicate relay failure, replace the electronic oven control board. Transfer all connectors carefully.
