The surface element switch — also called an infinite switch — is the rotary control behind each burner knob that regulates how much power reaches the heating element. It works by cycling the element on and off at varying rates to maintain the selected heat level. When the switch fails internally, the burner loses all heat control: it may stay permanently on high regardless of the knob position, produce no heat at all, heat only at one fixed level, or fail to turn off even when the knob is at zero. The WG02F12128 GE OEM Surface Element Switch is the factory-specified rotary infinite switch replacement with a quick-connect wiring harness for direct installation.
✓ Symptoms This Fixes
- Burner stuck on high heat regardless of knob position
- Burner will not turn off — element stays on even at the off position
- Burner produces no heat at any knob setting
- Burner heats at only one level — no variation between low, medium, and high
- Knob turns freely but has no effect on the element output
- Burner cycles on and off erratically with no pattern
- Burning smell from the switch area behind the knob
- Visible burn marks or melting on the switch body

A burner that produces no heat can be caused by a failed surface element switch or a burned-out heating element — both produce identical symptoms. Before ordering the switch, test the heating element for continuity with a multimeter. A good element reads a low resistance value (typically 10–40 ohms depending on wattage); an open reading means the element has burned out and is the correct part to replace, not the switch. If the element tests good but the burner still has no heat or no control, the switch is the fault. Also check that the knob shaft is engaging the switch stem fully — a cracked or stripped knob can cause the same symptoms as a failed switch at no cost to fix.
✓ Installation Notes
- Skill Level: Intermediate — requires access behind the control panel
- Estimated Time: 20–45 minutes
- Key Steps: Disconnect power at the breaker → Pull range away from wall for rear access, or remove the control console depending on model → Photograph the wiring harness connections to the switch before disconnecting → Disconnect the quick-connect harness from the switch terminals → Remove the switch mounting screws (typically 2) and pull switch out → Note the shaft orientation before removing — the new switch must be installed in the same rotational position → Seat new switch and secure mounting screws → Reconnect harness — confirm all terminals are fully seated → Reassemble console or rear panel → Restore power and test all heat settings from low to high
- Safety: Always disconnect power at the breaker before beginning. The surface element switch carries line voltage — never work on a live appliance. Confirm the burner turns off completely at the off position before returning the range to service.

✓ Frequently Asked Questions
How do I know if it’s the switch or the heating element that has failed?
Test the heating element for continuity with a multimeter — a good element reads a low resistance value (typically 10–40 ohms); an open reading (infinite resistance) means the element has burned out. If the element tests good, the switch is the fault. If the element is open, replace the element first — a failed element can also damage the switch over time.
Is WG02F12128 the same as WB23K5052?
Yes — WB23K5052, WB23X90, 342807, and WG02F04013 are superseded or cross-reference part numbers for the same GE range surface element switch. WG02F12128 is the current active OEM part number and is a direct replacement for all of these.
My burner won’t turn off — is this a safety emergency?
A burner that will not turn off is a safety concern. Disconnect power to the range at the breaker immediately and do not use the range until the switch is replaced. Do not attempt to operate the range with a switch that cannot be turned off.
