A malfunctioning oven or stovetop can be a major inconvenience. Instead of calling a repair service right away, you might be able to fix the problem yourself by testing and replacing the infinite switch on your Whirlpool range. Here’s a straightforward guide to help you through the process.
Understanding the Infinite Switch Function
The infinite switch regulates the power sent to your range’s burners. It controls the level of heat by cycling the current on and off. Here’s how it works:
- Off Position: No power is supplied to the burner.
- Intermediate Settings: Power cycles on and off intermittently to achieve the desired heat.
- High Setting: Continuous power is supplied for maximum heat.
When the switch malfunctions, it disrupts this cycle, causing issues like inconsistent heating or no heat at all. Replacing a faulty switch restores proper burner functionality.
Tools You’ll Need
- 1/4-inch nut driver
- Multimeter
Important Safety Measures
Safety should always come first when working on any appliance. Follow these precautions to avoid accidents or injuries:
- Unplug the appliance or turn off the circuit breaker before starting. This eliminates the risk of electric shock.
- If the appliance was recently in use, wait for it to cool completely before handling.
- Work in a well-lit, clutter-free area. Keep children and pets away to ensure a safe workspace.
- Avoid working with wet hands or in damp conditions. Make sure your workspace is dry.
- Check the user manual for any specific instructions or precautions related to your model.
- Use gentle pressure when removing or installing parts to avoid damage.
- Wear insulated gloves to safeguard your hands from sharp edges and debris.
- Consider safety glasses or a dust mask if dealing with dust, chemicals, or debris.
- When working with wires, don’t touch exposed terminals. Use non-conductive tools or insulated gloves.
- Take photos or notes of wire connections before disconnecting them. This will make reassembly much easier.
- If you’re unfamiliar with using a multimeter, avoid testing live voltage to prevent short circuits.
How to Test and Replace the Infinite Switch on a Whirlpool Range
1. Test the Infinite Switch
- Lift the cooktop at the front and secure it using the top panel brace bars.
- Use a 1/4-inch nut driver to remove the screws securing the user panel.
- Pull the user panel forward.
- Take a photo of the wire placement on the infinite switch for reference.
- Remove the orange wires from the infinite switch.
- Set your multimeter to continuity mode (sideways Wi-Fi symbol).
- Turn the switch to the “ON” position.
- Test continuity by placing the multimeter probes on:
- Terminal L1 and terminal H1.
- Terminal L2 and terminal H2.
- If no continuity is found, the switch has failed.
- If continuity exists, another issue is causing the problem.
2. Replace the Infinite Switch
- Remove the knob from the defective switch.
- Unscrew the mounting screws.
- Pull the faulty switch away from the panel.
- Align the new switch in the same orientation as the old one.
- Secure the new switch using the screws removed earlier.
- Reconnect the wires to the new switch, referring to the photo taken earlier.
3. Reassemble the Range
- Push the user panel back into place.
- Secure the user panel with the 1/4-inch screws.
- Replace the knob onto the new switch.
- Unlock the brace bars and carefully lower the cooktop.
- Replace the heating element.
- Plug the range back in or flip the breaker back on.

When to Call a Professional
While many issues can be resolved with DIY repairs, there are times when professional help is necessary. Consider reaching out to an appliance technician if:
- If replacing the infinite switch doesn’t resolve the issue, the problem might lie with other components, such as the wiring or burner itself.
- Working with electrical components can be hazardous if you’re not experienced. It’s better to consult an expert if you’re unsure.
- Signs of burnt wiring, melted components, or excessive wear may indicate broader issues requiring professional attention.
Conclusion
Replacing the infinite switch on your Whirlpool stove doesn’t have to be overwhelming. With the right tools, clear steps, and some patience, you can get your stove back in working order.
If things still aren’t running smoothly or you’re unsure about any part of the process, reaching out to a professional is always a smart move. Safety and peace of mind are worth it.
Now you’re ready to enjoy a fully functioning stove again—time to whip up something delicious!
