Brandt oven shows F05 and trips the breaker or does not heat.

Safety first: Disconnect power and verify the breaker is off before touching any wiring or elements.

Steps:

• Visual inspection: Look at the bake and grill elements inside the oven for blisters, cracks, or burn marks.
• Check continuity: Remove at least one wire from each element terminal and measure resistance with a multimeter. An infinite reading indicates an open element; near-zero ohms or tripping breaker suggests a short.
• Inspect wiring: Check that element wires are not touching the metal chassis and that insulation is intact.
• Replace faulty element: Install a new Brandt bake or grill element if defective. Ensure all connections are tight.
• Test operation: Restore power and test each heating function separately to confirm normal operation.
