The relay control board on an electric Samsung range ends power to the heating elements of the unit so it can control the temperature. Over time, regular use can cause the relay control board to wear out or become damaged. But with a few basic tools and some patience, you can tackle this repair yourself and get your range back up and running. Let’s get started!

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 you attempt any maintenance or replacement work. This keeps you safe by eliminating any risk of electric shock.
  • If the appliance has recently been used, give it plenty of time to cool down before working on it.
  • Take your time while working to prevent accidents and personal injuries. Rushing is the enemy of precision.
  • Work in a well-lit area so you can see and access appliance parts.
  • Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
  • Never work on internal parts with wet hands. Make sure the work area is completely dry.
  • Check the user manual to see if there are specific installation or safety instructions related to your appliance or replacement part.
  • Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
  • Wear insulated work gloves to protect your hands from sharp metal parts and debris.
  • 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.
  • Always take photos or make a note of wiring terminals or other connections before disconnecting them to make reassembly easier.
