The W11129442 is the OEM surface element infinite switch for Whirlpool-platform electric ranges and cooktops. The infinite switch is the control behind your burner knob — it regulates how much power reaches the surface element by rapidly cycling the element on and off at varying intervals. When it fails, the burner may not heat at all, stay stuck on one temperature, or produce inconsistent heat that makes precise cooking impossible.

The W11129442 infinite switch uses a bimetal strip mechanism that flexes with heat to interrupt and restore current to the surface element. Unlike a simple on/off switch, it modulates power continuously across the full dial range from low simmer to high boil. A failed switch typically presents as a burner that won't respond to the knob, heats only at full power, or won't turn off. This part supersedes W10437097.

✓ Installation Tips

• Disconnect power to the range at the breaker before beginning any repair

• Note the wire terminal positions before disconnecting — photograph the existing wiring
• Disconnect the wire terminals from the old switch and remove the mounting hardware
• Install the new switch in the same orientation and reconnect the wires to the matching terminals
• Restore power and test all heat settings from low to high before reassembling the panel

✓ Frequently Asked Questions

Is W11129442 the same as W10437097?
Yes — W11129442 is the updated OEM part number that supersedes W10437097. It is a direct replacement with no modifications required.

How do I test an infinite switch?
Use a multimeter set to continuity. With the switch in the off position, there should be no continuity between the element terminals. As you rotate the switch toward high, you should get continuity. A switch that shows continuity in the off position or no continuity at any setting has failed. Contact us if you need help diagnosing.

Can I replace just one infinite switch or do I need to replace all of them?
You only need to replace the failed switch. Each burner has its own dedicated infinite switch, so replacing only the faulty one is the correct approach.

Will this switch fit my range?
