WB24T10029 GE Oven Burner Infinite Switch is an electromechanical control component used inâ GE electric ranges andâ similar appliances⤠too regulate the â˘power delivered to a heating element. It is indeed a rotary âinfiniteâ selector⤠that provides a range of heat settings by cycling line voltage to the element âŁrather than âproviding a smooth electronicâ outputand it â¤is builtâ to âmatch the electrical âratings and terminal layout required by the appliance âmanufacturer.
Inside an appliance⤠the⢠infinite switch serves as the user-facing control interface between the range’s â¤power supply â˘and âthe heating element; âŁit receives input from the control knob âŁand interrupts or appliesâ line â˘voltage toâ the element according to the selected setting. It interacts⣠directly with the element and the appliance âwiring harnessand indirectly with related control and safety systems (such as thermal cutouts, main control boardsand⤠terminal blocks).As a line-voltage âswitching device, its correct operation is critical to maintaining predictable element⤠temperature, avoiding overheatingand ensuring safe electrical connections.
This article will describe the WB24T10029’s functional design and operational principles, outlineâ model compatibility and cross-reference considerations, identify common failure symptoms (for âexample, inability âto change heat level, intermittent operation, âor visible arcing)and present systematic troubleshooting tests a technician can perform. It will also cover practical replacement considerations,including⢠matching electrical ratings and terminal âarrangements,safeâ isolation of power duringâ service,and installation⣠notes relevant to appliance â¤owners and service technicians.

Function and âRole of the â¤WB24T10029 GE Oven Burner Infinite switch in âOven Temperature and Power Regulation
The WB24T10029 GE Oven Burner⢠Infinite Switch is a ârotary, â¤line-voltage⤠control that modulates power delivered âto the oven’s heating element by selecting discrete power taps âand by⣠rapidly⢠switching theâ supply on and off to create an effective duty cycle. â˘In practice this mechanical â¤device provides graduated heat settings⣠rather than âa true continuous temperature control: the knob selects a contact position âŁ(power level) â˘and an âinternal cam/timer commutates the mains supply to the element for a â˘proportion of each cycle. As it controls â¤mains current directly, the part must match the appliance’s wiring configurationâ and voltage rating; confirm the oven model and terminal functions before replacing the control to ensure safe, compatible operation.
Technically, the switch â¤functions as the user-side power selector âwhile the oven thermostat or electronic controller defines setpoint control;â the infinite switch changes the proportion ofâ time the â˘element sees full mains voltageâ to achieve different bake intensities. Technicians will recognize failure modes such as no heat, intermittent heatingor âinability toâ vary temperature as symptoms of âcontact âwear, internal shortingor a âfailed cam mechanism. For diagnosis and replacement, â˘verify terminal continuity âŁat multiple knob positions and compare âŁwiring layout to the replacement unit; disconnect mains power â¤before testing or swapping the WB24T10029 GE oven Burner Infinite Switch to avoid electrical hazard.
- Common symptoms: no heat, stuck-on âelement, uneven heating, audible clicking that changes⢠or âstops
- Service check:⣠continuity across terminals variesâ with knob position;â consistent fullâ continuity at all positions indicates failure
- Compatibility tip: match terminal layoutâ and voltage rating â¤to oven wiring âdiagram

How the WB24T10029 GE Oven Burner⣠Infinite Switch Works Inside the Appliance: Electricalâ Pathways,â Wiper Contactsand Control Mechanisms
The WB24T10029 GEâ Oven Burner Infinite Switch âis aâ rotary power-control â¤switch that regulates⣠ovenâ element heat by routing lineâ voltage through a sequence of fixed resistive segments and a moving wiper contact. As the selectorâ is turned, âŁthe wiper bridges different points of⢠the internal resistive network so â¤that âŁthe element receivesâ varying âproportions of on-time versus off-time (a stepped duty cycle) ratherâ than continuously varying voltage. Electrical pathways âinside the switch include the incoming line connection, the resistive ladderâ or contact padsand the output terminal(s) to the bake element; at low settings the wiper encountersâ higher resistance and more frequent open intervals, while at high âŁsettings the wiper bridges low-resistance paths to deliver near-continuous line âvoltage. The mechanical design (detents, shaft fit) and contact âŁmaterials determine long-term behavior: worn or pitted wipersâ increase contact resistance, produce arcing,â and change the expected cycle timing under load.
Technicians âassess compatibilityâ and diagnose the⢠part byâ checking terminal layout, voltage ratingand dynamic continuity across positions. Practical tests include measuring continuity or resistance from the incoming line terminal to theâ element output while⢠rotating the knob to â¤verify smooth, progressive changes in contact⣠connectivityand observing âfor⤠visible contact pitting or âcarbon tracking that indicates replacement. Common service symptoms tied to this component are intermittent heating, loss ofâ low-end modulation (element only heats âat full)or audible â˘arcing/clicking under load; replacing the switch requires matching the mounting, shaft dimensionsand terminal configuration to âthe appliance wiring harness âto ensure correct function and safe operation.
- Diagnosticâ checks: visual inspection,continuity/resistance sweep across knob positions,and load observation for⢠arcing or inconsistent cycling.
- Compatibility: confirm terminal layout, mounting holes,â shaft type, âand voltage/current rating before⣠replacement.
- Failure indicators: pitted/wornâ wiper contacts,unstable duty-cycle behavior,orâ high contact resistance under load.

Common Failure Symptoms and Diagnostic Indicators of a Faulty⢠Oven Burner Infinite Switch
The WB24T10029 GE Oven Burner Infinite Switch is a âŁrotary power-control device that modulatesâ the oven burner’s âapplied voltage by selecting different contact taps as the knob is rotated. In normal operation the switch provides stepped duty cycles or progressively lower resistance paths so the heating element receives varying average power rather than a simple on/off signal; this allows temperature controlâ and predictable heat-upâ characteristics. Compatibility is⢠determined by terminal⣠arrangement andâ mounting âstyle, so the WB24T10029⤠must match the oven’s wiring harness and panel cutout;⣠improper âŁfit orâ swapped terminals âcan create symptoms identical âto a failed element or thermostat.
- oven only heats⣠on⢠the highest setting âŁor not at all
- intermittent heating or erratic cycling â(sudden on/off behavior)
- Visible burning, meltingor arcingâ at the switch housing âor terminals
- Knob position does not change heat output or âthe âcontrol feels loose/gritty
| Item | Description |
|---|---|
| Open circuit at all positions | Internal contact failure – âmultimeter shows no continuity between line and load terminals across settings |
| Low resistance only at⢠maximum | Contact welding or â¤loss of intermediate taps – element only receives full⣠power on the âŁhigh setting |
Technicians diagnose the switch byâ isolating power and performing a visual inspection for heat⢠damage, then âŁusing a multimeter âto â˘verify continuity and variable⢠resistance as the shaft is rotated through its range; a correctly âfunctioning unitâ will present different electrical â˘paths at different knob positions⢠and no continuity⣠in the OFF position. Practical examples include an oven that remains cold because the switch’s âinternal open circuit prevents current from reaching the elementor â˘an âoven that⢠stays on âor cycles unpredictably because contacts⤠are shorted, pittedor intermittently connecting – in those⢠cases⤠replacing the WB24T10029 GEâ Oven Burner Infinite Switch with an identical part âand confirming terminal wiring typically resolves the â˘fault.
Replacement Considerations, Compatible Appliance Modelsand Installation Best Practices
The WB24T10029 GE Oven Burner Infinite Switch is a rotary power selector that modulatesâ power to an ovenâ orâ cooktop heating element â¤by intermittently switching line voltage through internal contacts; it provides stepped or “infinite” heat settings rather than a⢠continuously variable output. Technically, the unit contains a âcam-operated switch⢠and multiple spade â¤terminalâ outputs; wear or pitting⢠on the contacts, broken cam assembliesor failed internal insulation produce common symptoms suchâ as loss of heat at certain â¤settings, erratic cycling, â˘or visible arcing at terminals. Compatibility⢠depends on matching the part number,the âelectrical rating âstamped⤠on⢠the unit,the â˘terminal labeling/spacing,shaft âdiameter/length and mounting bracket â˘geometry-mismatches in any of these areas can prevent proper fit or create â¤unsafe electrical connections. â˘Before replacing, compare the replacement â˘switch’s terminal map and amperage rating to the original and consult the appliance wiring diagram to confirm function mapping (e.g., which terminals feed bake, broil, â˘or surface elements) so the new switch will⢠reproduce âthe original control behavior.
- Verify OEM part number⣠and physical form factor (shaft, bracket, depth)â against âthe appliance before âpurchase.
- Confirm electrical ratings and terminal labeling match the original;â test âcontinuity â˘across positionsâ with a multimeter.
- Document and â¤photograph all wiring connections⢠before removal âto ensure correct reassembly.
- Use appropriately⤠sizedâ crimpâ connectors or spade âterminals and route wires away from âheat sources to prevent â˘insulation failure.
| Item | Description |
|---|---|
| Electricalâ rating | Check stamped voltage/amperage on part; âreplacement must meet or⣠exceed â¤original rating |
| Terminals | Spade-style outputs; verify labels⣠and spacing to match wiring harness |
| Mounting | bracket shape, screw⢠pattern and shaft⢠dimensions determine mechanical compatibility |
| Serviceâ check | Continuity across contacts at each⢠knobâ position; inspect for pitting or carbon tracks |
During installation, disconnect all power and âverify absence of voltage before touching terminals. Reassemble wiring to the documented configuration and make secure, low-resistance connections-loose spade fittings increase contact heating and âaccelerate failure. After installation, perform â¤functional verification by measuring continuity or â¤voltage at the âexpectedâ terminals across several selector positions and observing the heating element’s on/off⢠cycling⢠at low and high settings;â this confirms correct wiring and contact operation without requiring⣠full bake cycles. For long-term âreliability, avoid forcing the knob onto an incompatible shaft, keep lead⣠wires clear of sharp edges âand high-temperature componentsand replace any âŁbrittle insulating components that could allow shorting or arcing near the switch.
Q&A
What is the WB24T10029 infinite âswitch and what does âit control?
The WB24T10029 is⣠an “infinite” or rotary control switch used on many GE ranges to â¤vary power to a surface⤠(cooktop) heating element. It is indeedâ not a â˘thermostat – it is a variable electrical switch (a stepped/continuous resistorâ or selector) that regulates how long the element receives mains voltage at each knob position â˘to control â˘heat output.
What areâ common symptoms â˘that âŁthe WB24T10029 has failed?
Common signs include a burner â¤that won’t heat at â˘all orâ only heats on some â¤knob positions, the elementâ stuck at one â˘heat level, intermittent or flickering heator the knob turning but no change in temperature. âBefore replacing, check the element, element socket, wiring and circuit breakers – those frequently enough mimic a bad switch.
Howâ do I test the WB24T10029 with a multimeter?
First disconnect âpower to â¤the range.â Remove the control knob and access the back of the switch. With âan ohmmeter, check continuity between the common â˘(line) terminal and the output terminal âfor the element while rotating the shaft through positions -⢠you shouldâ see changes in resistance/continuity⣠as the knob âmoves (no continuity at OFF, continuity at higher settings). A proper âtest also includes a live-voltage check (performed by a qualified technician):⤠with power restored and element connected,the switch should â˘supply voltage to the element output terminal when âŁthe knob isâ turned on. If you are not âagreeable working withâ live mains, call a technician.
do I⢠need to replace the whole âŁcontrol panelâ or âjust the WB24T10029 switch?
Usually justâ the infinite switch is replaced. The WB24T10029 is a discrete replaceable component⣠mounted in the control panel. Replace only the switch unless there is additional damage to the control panel or⢠wiring. Always verify compatibility with your ovenâ model âand verify the âsymptom is â¤isolated to⤠the switch before buying parts.
Howâ do I replace the WB24T10029 safely?
Turn off â˘all power to the appliance at the âbreaker and, for gasâ ranges, turn off the gas supply if work â¤affects valve/ignitionâ areas.Remove the â¤control knobs, open the âconsole or back panel to access the switch, note or photograph all wire⣠locations, disconnect âthe wires, remove the mounting nut or âscrewsandâ swap in the new switch. Reconnect wires exactly as they were, âreassemble, restore â˘powerandâ test. If you’re unsure or uncomfortable working on mains wiring, hire a â¤qualified appliance technician.
What wiring or terminal labels â˘should⣠I look for when replacing this switch?
Terminals are usually labeled or color-coded for line (hot),⣠load (to the element), â˘and sometimes for a pilot/light or second pole. Beforeâ removing wires,⣠take a photo or mark them. If uncertain, consult your ârange’s wiring diagram (usually âon theâ oven âframeâ or behind the âkick plate) or⤠a parts âschematic to confirm terminal designations. Always ensure power is off when handling wiring.
Is WB24T10029 âcompatible with⣠my GE range model and are thereâ cross-reference part numbers?
Compatibility depends onâ the specific GE model numberâ and control panel configuration. WB24T10029 is used â˘on many GE/Hotpoint/Jenn-Airâ models, but you should confirm by checking your appliance model ânumber and the OEM parts lookup or a reputable parts supplier. Do not assume âŁinterchangeability withoutâ verification; some⣠switches look âsimilar but have different terminal arrangements or shaft âŁdimensions.
How much does the WB24T10029 cost and where can I buy one?
Prices⣠vary by vendor and new vs. aftermarket part, typically ranging âfrom about $20 to $80 USD. Buy from authorized GE parts dealers, appliance parts storesor reputable onlineâ retailers.Avoid nonâverified sellers if possible,and confirm the⢠part number and return policy before âŁpurchasing.
