Range trips the circuit breaker or RCD when oven or cooktop is turned on

Safety first: Do not repeatedly reset a tripping breaker. Disconnect the appliance and do not use until inspected.

• Visual inspection: Remove rear and bottom panels. Look for burnt wires, melted insulation, or signs of arcing.
• Element insulation test: With a megohmmeter (insulation tester), check each heating element to earth. Low resistance indicates leakage and the element should be replaced.
• Terminal block: Inspect the mains terminal block for loose or burnt connections. Tighten and replace damaged parts.
• Moisture: If the fault occurred after cleaning, allow the unit to dry thoroughly before retesting.

Warning: Earth leakage and short circuits are serious safety hazards. If you are not trained, contact a qualified electrician or service technician.
