If the burner on your Frigidaire or Electrolux range isn’t heating properly, a faulty infinite switch (also called a control switch) could be the problem. This switch controls the flow of electricity to the burner, so replacing it can help restore normal function.
The good news? This is a relatively simple DIY fix that requires only a few tools. Follow this guide to safely and efficiently replace the switch and get your range working again.
Common Signs of a Faulty Infinite Switch
If you’re unsure whether the infinite switch is the issue, look for these common symptoms:
- The burner doesn’t heat up at all, even when turned on.
- The burner gets too hot, regardless of the temperature setting.
- Heat levels fluctuate unpredictably while in use.
- A clicking or buzzing sound comes from the control switch.
- The switch knob feels loose or unresponsive when adjusting heat.
What You’ll Need
- 1/4-inch nut driver
- Phillips head screwdriver
- Needle-nose pliers
- Towel or pads
- Magnetic tray or small container
- Replacement switch (Part #: 316436001)
Safety Precautions
Before starting, always prioritize safety. Follow these precautions to avoid injury or damage to your appliance:
- Turn off the power: Unplug the range or switch off the circuit breaker to prevent electrical shock.
- Allow the range to cool: If it was recently used, wait until all surfaces reach room temperature.
- Work carefully: Move slowly and deliberately while handling appliance components.
- Handle wires with care: When disconnecting switch wires, grip the plastic connectors instead of pulling on the wires directly.
- Lift components gently: Avoid putting pressure on delicate control boards or wiring.
- Wear protective gloves: This helps prevent cuts from sharp metal edges and pinching injuries.
How to Replace Infinite Switch on a Frigidaire/Electrolux Electric Range
Preparation
- Unplug the power cord from the wall outlet or switch off the breaker to cut power to the range.
- Confirm the power is off by attempting to turn on a burner.
- Gather necessary tools, including a 1/4-inch nut driver, Phillips head screwdriver, and needle-nose pliers.
- Place a towel or soft cloth over the cooktop to prevent scratches during the repair.
Accessing the Control Panel
- Use a 1/4-inch nut driver to remove the screws securing the top rear area of the control panel and set them aside.
- Use a Phillips head screwdriver to remove the screws on the far left and right sides of the control panel and set them aside.
- Grasp and pull outward on the plastic end caps at both ends of the control panel to remove them.
- Tilt up and lift the entire control panel, propping it upright to access the rear wire connections.
Removing the Faulty Infinite Switch
- Identify the faulty large surface element control switch on the panel.
- Pull the switch knob directly outward to remove it from the stem.
- Use a Phillips screwdriver to remove the two screws securing the faulty switch to the control panel.
- Take a clear, close-up photo of the wire connections on the back of the faulty switch for reference.
- Note the wire colors and terminal labels before disconnecting them.
- Use needle-nose pliers to remove each wire from the terminal connections carefully.
- Gently pull the faulty switch out of the panel holes to fully remove it.
Installing the New Infinite Switch
- Use needle-nose pliers to gently squeeze the ends of the wire connectors and attach them to the new switch.
- Refer to the photo taken earlier to match wire placement by color and terminal position.
- Align the new switch into place and insert it into the control panel holes.
- Use a Phillips screwdriver to tighten the two mounting screws securely.
Reassembling the Control Panel
- Lower the control panel back into its original position.
- Check for any loose wire connections and tighten if necessary.
- Slide the switch knob onto the switch stem until it is fully seated.
- Align the tabs on the plastic end caps into the slots on the control panel and press them into place.
- Reinsert the two bottom screws and two top screws that were removed earlier.
Restoring Power and Testing
- Plug the range back in or flip the breaker switch back on.
- Turn the burner knob to different heat settings and check that the element functions correctly.
Maintaining Your Range for Longevity
Regular maintenance can help extend the life of your range and prevent future issues:
- Clean spills immediately: Food residue can cause buildup around burner controls.
- Check for loose knobs: If a control knob feels wobbly, inspect the switch shaft for wear.
- Inspect burner elements: Warped or damaged elements can lead to uneven heating.
- Test all burners periodically: If one burner malfunctions, others may soon follow.
- Keep vents clear: Proper airflow around the range prevents overheating and electrical failures.
A little maintenance goes a long way in keeping your range working efficiently.
Final Thoughts
Now that you’ve replaced the switch, your stove should be working as expected. If you notice similar problems in the future, you’ll know where to start. Keeping your range in good condition helps avoid bigger issues down the road. Wipe up spills quickly, check for loose knobs, and keep an eye on burner performance.
If your stove acts up again, you won’t have to second-guess what to do. Grab your tools and fix it with confidence.
