Tools and materials
- Multimeter
- Phillips head screwdriver
The specific tools required may vary depending on the model of your appliance and the type of fasteners used on it. Always consult the user manual or refer to any specific instructions provided by the manufacturer for the recommended tools for your appliance model.
Safety precautions
When working on any appliance, remember to keep safety first. Here are some tips to keep in mind:
- Always power off and unplug your appliance or switch off the circuit breaker before attempting any maintenance or replacement work. This keeps you safe by preventing any risk of injury from electric shock.
- Wear insulated work gloves to protect your hands from sharp metal parts, pinching hazards and debris.
- Take your time and don’t rush while working to prevent accidents and personal injuries.
- Work in a well-lit area so you can clearly see and access the interior parts.
- Clear your workspace of clutter and other obstacles. Keep children and pets away from the work area.
- Never work on internal parts with bare wet hands. Make sure the work area is completely dry.
- Check your user manual to see if there are specific installation or safety instructions for your part or appliance.
- Be gentle when handling or removing parts. Excessive force might damage the appliance or cause injury.
- Wear safety glasses when working with chemicals, dust or cleaning large debris to prevent injury.
- If the appliance has recently been used, give it plenty of time for any heating parts to cool down before working on it.
- Take pictures or make a note of wiring terminals or other connections before disconnecting to prevent any problems with reassembly.
- When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
Testing steps
- Unplug the electric range from the power source or turn off the circuit breaker supplying power to the range.
- Locate the rear terminal cover on the back of the range. This is usually secured with Phillips head screws. Use a Phillips head screwdriver to remove the terminal cover.
- Visually inspect the wiring, power cord connections, and the terminal block itself. Look for any signs of damage, burning, or excessive heat.
- If you see any burned or damaged components, you will need to replace the terminal block and the power cord.
- If the wires on the range are burned, you can try splicing in new wiring or replacing the entire wire harness.
- If the terminal block and wiring look to be in good condition, the issue is likely something else and you’ll need to continue troubleshooting.
- Once the inspection and any necessary repairs are complete, replace the terminal cover and secure it with the Phillips head screws.
- Restore power to the range and test to see if the oven now heats properly.
