The dual infinite switch on your Samsung electric range controls how much power reaches the heating elements. If your right front burner isn’t working properly—maybe it’s overheating, underheating, or shutting off unexpectedly—you might be dealing with a faulty switch. The good news is, you can replace it yourself without hiring a technician.
What Is the Right Front Dual Infinite Switch?
The dual infinite switch lets you adjust the burner temperature by controlling the flow of electricity to the heating elements. As you turn the knob, the switch gradually opens and closes internal contacts, which increases or decreases the heat.
A faulty switch can cause issues such as:
- Inconsistent or fluctuating heat
- Burners that won’t reach the desired temperature
- Sudden loss of power to the burner
- Uneven or incomplete cooking
If you’re experiencing any of these problems, it may be time to replace the switch.
Common Signs of a Faulty Switch
Before committing to a replacement, it’s helpful to confirm the symptoms match a failing infinite switch. Look for:
- Burner heats up only on high or not at all
- Burner temperature is hard to control
- Burner doesn’t turn on, even when the knob is turned
- Burner shuts off randomly during use
- Visual signs of damage behind the control knob (e.g., scorch marks or melted plastic)
- Clicking or popping noises when adjusting the knob
- One side of the dual burner works while the other does not
What You’ll Need
- Replacement right front dual infinite switch (make sure it matches your specific Samsung range model)
- Phillips head screwdriver
Safety Precautions Before You Start
Before starting any appliance repair, it’s important to follow basic safety practices:
- Always unplug the range or turn off the correct circuit breaker. This prevents electrical shock.
- Let the appliance cool completely if it has been used recently.
- Work slowly and carefully to avoid injury or damage.
- Use a well-lit and clean workspace.
- Keep children and pets out of the area.
- Only work with dry hands. Do not touch internal parts if the area is wet.
- Check your user manual for any model-specific instructions.
- Handle components with care to avoid damaging them.
- Wear insulated gloves to protect your hands from sharp parts or electrical components.
- Take a photo or make a note of wire connections before removing them to help with reassembly.
- Use non-conductive tools or insulated gloves when working with wires.
- Safety glasses and a dust mask can help protect you from debris and irritation if needed.

What’s Next?
Once you’ve swapped out the switch and tested everything, you’re pretty much done. If the burner is heating the way it should and the controls feel smooth and responsive, then the fix was a success. It’s always satisfying to take care of something like this on your own, especially when it saves time and money.
Keep an eye on how the burner behaves over the next few uses. If anything still feels off, double-check the wire connections or consider whether another part might be involved. But in most cases, replacing the switch clears up the issue.
Staying familiar with your range and knowing how to handle small repairs like this one can go a long way. It gives you a bit more control and confidence when something stops working the way it should.
