The relay control board in your Samsung electric range controls the power sent to the heating elements, which allows the oven to heat properly. Over time, regular use can cause this part to wear out or stop working. Fortunately, with a few basic tools and some patience, you can replace it yourself. Here’s how to do it.
Common Signs of a Faulty Relay Control Board
Knowing the symptoms can help you confirm the issue before starting the repair:
- Oven does not heat up at all
- Heating elements turn off unexpectedly during cooking
- The range display is on, but there is no heat in the oven or burners
- Error codes related to heating issues appear on the display
- Burners or oven elements remain stuck on and cannot be turned off
- Burned or melted areas on the board itself (visible after opening the panel)
Why the Relay Control Board Fails
Understanding the causes behind the failure can help you avoid future problems:
- Prolonged high-temperature exposure during extended cooking
- Power surges or electrical spikes
- Moisture or spills entering internal components
- Worn-out relays from frequent use
- Faulty wiring or loose connections
- Overloading circuits by using high-powered features simultaneously
- Poor ventilation around the appliance
Tools You Will Need
- Phillips head screwdriver
- Multimeter
- Wire stripper
- Adjustable wrench
- Flashlight
Safety First
Before you begin any work on your appliance, take the necessary precautions to stay safe and avoid damaging the unit:
- Always disconnect the range from power by unplugging it or turning off the circuit breaker.
- If the appliance has been used recently, allow it to cool down completely before beginning any work.
- Work at a steady pace to reduce the risk of injury or errors.
- Make sure your workspace is clean and well lit. Keep pets and children out of the area.
- Do not work with wet hands or in a damp environment.
- Refer to the user manual for any specific safety or installation instructions for your model.
- Handle all parts carefully to avoid damaging the appliance or injuring yourself.
- Wear insulated gloves to protect your hands from sharp edges or debris.
- Avoid direct contact with exposed wires or terminals. Use insulated tools or gloves when needed.
- Take photos or make notes of wire connections before disconnecting anything. This will help you reconnect everything correctly later.
