WB24T10029 GE⢠Oven burner Infinite Switch â˘is an electromechanical infiniteâ control switch used â¤on GE⢠electric ranges to âvary the âpower delivered to a heating element. It is indeed a rotary, â¤multi-position device that provides stepped or âŁcontinuously variable controlâ of⢠current to an oven or surface burner by opening⤠and closing internal contacts according to theâ user-selected setting. As a field-replaceable control component, âŁitâ combines electrical âswitching contacts, aâ mechanical actuator⣠for âthe control knoband terminal connections for the element â¤and power âŁfeed.
Inside the appliance,the infinite switch sits between the line-voltage supply and⣠the heating⤠element and is operated directly by theâ range control â¤knob.⢠Its primary ârole is to modulate heating by cycling â˘the element on and âoff (or switching among discrete tap settings) to â¤achieve a âŁperceived intermediate heat level; it âtherefore interacts⢠withâ the mainsâ feed, âthe heating element â¤circuit, the⢠front control paneland â¤any indicator lamp or interlock circuitsâ routed through the sameâ terminal cluster. The switch must match the element’s â˘voltage and current characteristics andâ can also âbe affected⤠by related â¤protections such as thermalâ fuses, â¤thermostats, âor electronic control modules inâ rangesâ with hybrid control architectures.
This âarticle explainsâ the WB24T10029’s functional âprinciples, physical and âelectrical compatibility considerations, common failure symptoms â(for example: no heat, element stuck on,⣠intermittent⤠operationor failed indicator lamp), â¤and a practical troubleshooting âŁapproach for technicians and experienced appliance owners. âIt âwill also cover multimeter-based checks to assessâ continuityâ and contact behavior, safety and isolation best practicesand âreplacement considerations including correct⣠part selection, terminal âidentification, mounting orientation, âand basic reassembly notes to restore safe, predictable operation.

Functional Role of theâ Oven⣠Burner Infinite âSwitch in âŁHeat Regulation⢠and Safety Interlocks
The WB24T10029 GEâ Oven Burner â¤Infinite âSwitch âcontrols heat output by selectingâ contact paths and timing cycles as the user rotates the control knob; this action⢠modulates the duty cycleâ delivered to the oven burner rather than producing a continuously variable analog voltage. â˘In service practice the âŁswitch serves as both the user interface and âthe power-distribution â˘element for bake/broil⢠circuitsand must be âmatched to âthe appliance⤠by terminalâ layout, mounting flange and electrical â˘rating to ensure compatibility â˘with⤠theâ range’sâ thermostatâ and wiring harness. Because âthe infinite switch works in concert with thermal cutoutsâ and the oven thermostat,⣠failuresâ can present as control or safetyâ issues that require confirming both electrical âŁcontinuity and⣠correctâ integration with the interlock components before⤠replacement.
- Typicalâ failure behaviors: no heat, continuous heat (stuck âŁcontacts), erratic cycling or inability to hold set⣠temperatures.
- Operational role: switches between timed contact closures to vary power; interfaces with thermostat and high-limit âdevices.
- Replacement⤠considerations: âverify⢠terminal configuration, mountingand OEM cross-reference before installation.
Technicians diagnose the switch by first âisolating power, thenâ measuring â¤continuity across âthe appropriate⢠terminals as the control is stepped through positions âŁand by⢠verifyingâ the switch⤠under load â¤where safe; absence of expected⤠contact â¤closures âorâ burned/oxidized contacts indicates⢠replacement. â˘confirming theâ integrityâ of âsafety interlocks (high-limit thermostat, thermal fuse) is necessary âŁbecause those devices can open â˘theâ circuit externallyâ and mimic âswitch failure; ensureâ the⤠replacement WB24T10029 unit matches the original’s terminal ânotation and rating,⣠and secure â¤all spade âconnections and ground returns to restore correct operationâ and maintainâ required⣠safety interlocks.

How âthe WB24T10029 GE Oven â¤Burner Infinite Switch Operates: Internal Components,Contact Paths,and Controlâ logic
The WB24T10029 â˘GE Oven âBurner Infinite Switch controls heat output â˘by varying the duty cycle delivered âto the âoven burner through â¤a cam-driven â˘contactâ arrangement â˘and an internal timing element. Inside the enclosure a rotary selector (camâ and wiper) physically routes power â¤through aâ set of⣠fixed contacts; an internal heater and bimetal timing âspring â(or â¤equivalent thermal⣠timing mechanism) modulates⣠how long the⢠wiper completes⢠the circuit â¤each cycle. The result is a variable â¤on/off percentage at the âŁburner that produces âa continuum of heat settings rather than discrete âsteps. Replacement âand compatibility require âŁmatching âthe WB24T10029 GE Oven Burner Infinite Switch’s terminal layout, mounting bracketand electrical rating to the range model so thatâ theâ contact paths âand mechanical indexing align with the wiring harness and â˘control knob shaft⤠used by âthe⤠appliance.
Contact path behavior isâ simple in principle but practical in diagnosis: turning â¤the knobâ moves the cam so the movable â˘contact spends more or less time touching the live contactand the internal heater/bimetal âadjusts timingâ to smooth transitions andâ provide repeatable cycles at each setting. Common symptoms of a failing infinite â¤switch include weak or noâ heat at âhigher settings, rapid â¤on/off chatter, visible â¤arcing âon terminals,â or loss of continuity when the knob⣠is rotated;⤠technicians can verify operation by⢠measuring continuity between the incoming line and the â˘load terminal as the shaft is turned and by inspecting the heater/bimetal assembly for discoloration or deformation. For safe replacement, compare terminal⢠labels and confirm the switch’s â¤voltage and â˘current⢠rating âagainst âthe oven’s nameplate; âif intermittent â˘cycling orâ contact pitting is observed, replacement is usually the practical remedy rather than attempting to recondition the internal contacts.
- Quick checks: continuity between⣠line⢠and load whileâ rotating knob; visual inspection for burned contacts or broken cam lobes.
- Symptoms: ârapid cycling at a fixed setting,no heat onâ high,or mechanicalâ stiffness when turning the⢠shaft.
- Compatibility: confirm terminal layout, knob shaft diameterand electrical rating âbefore â˘replacing.

|---|---|
| Selector cam andâ wiper | Rotary mechanism that establishes how long⤠the live contact is closed at each setting. |
| Bimetal/timing heater | Generates the timedâ off periods by âheating and bending the â¤bimetal, creating a repeatable duty cycle. |
| Contact assembly | fixed and movable contacts that carry theâ burner current;⢠wear here causes arcing and loss of function. |
| Terminals | External connectionsâ for line, load (to burner element), â˘and any internal return/sensingâ circuit; must match appliance wiring. |
Common Failure Symptoms â˘and StepâbyâStepâ Diagnostic Tests for Infinite Switch Malfunctions
The WB24T10029 GE Oven âBurner⣠Infinite Switch is a ârotary⤠power-control device that⢠regulates current to the oven burner by changing contact positions and internal resistance âŁsteps as âthe â¤knob is rotated. Technically, the switchâ provides⣠stepped⢠orâ variable resistive paths and⤠contact closures between the â˘lineâ input andâ the heating element, allowing proportional heat output without a thermostat. Typical malfunctionâ behaviors include loss of heating,the element receiving âfull â¤line âvoltage regardless of setting,erratic on/off âcycling,excessive heat or arcingâ at âŁthe console,and knob positions that do not correlate to expected⤠power levels. Compatibility is â¤largely mechanical and electrical: the âŁswitch⤠must â¤match the oven’s âŁterminal layout and voltage ârating, â˘and⤠terminalâ labeling in â¤theâ appliance âŁwiring diagram should â˘be verified before replacement or âbench testing.
- No heat⤠at any setting; âŁcontinuity â¤absent â¤across output âcontacts.
- Full-power heating at all settings;â shorted internal contacts or stuck closed.
- Intermittent heating or funny cycling; worn âorâ pitted contacts causing unreliable closures.
- Visible burning, melted insulationor âarcing at terminals; âŁimmediate replacement recommended.
- Knob positions mismatched âtoâ output; internal cam/selector fault or broken âŁdetent mechanism.
Diagnostic testing proceeds from non-powered inspection to live verification: first,disconnect power and visuallyâ inspect the switch for burned terminals,melted plastic,or oil/contaminant ingress⢠that â˘canâ explain intermittent contacts. Withâ power still off, use a multimeter to check âŁcontinuity between the common/line terminal â¤and each⤠output terminal while rotating the control through its detents -⣠you should see continuity âchange predictably asâ the â¤knob indexes⤠through âŁhigher â¤settings. â˘If âequipped âwith resistance specifications in âthe service âmanual, measure cold resistance between terminals at severalâ settings and compare to the âdocumented pattern; âlargeâ open circuits or constant zero/near-zero resistance across⤠all positions indicate failure.For a controlled live⤠test, restore power âand measure voltage at the element terminal âwhile commanding â¤severalâ settings (use insulated â˘probes and appropriate safety precautions); absence of â¤expected line âŁvoltage at higher settings or voltage âpresent at⤠the âelement when the switch⢠is off confirms internal contact failure. If tests show open circuits, âŁburnedâ contactsor unstable â˘readings, replacement âwithâ a âŁcorrectly configuredâ WB24T10029 or specified equivalent is the recommended⤠remedy.

Compatibility,⢠Replacement Considerationsand Installation Guidelines for WB24T10029
the WB24T10029 GE⣠Oven Burner Infinite Switch â˘is a rotaryâ power-control âswitch that âprovides variableâ regulation of current â˘to an oven⣠burner elementâ through a seriesâ of discrete⣠contact positions rather than sensing temperature. It âroutesâ mains voltage through selectable resistive/contact paths to the⣠element, allowing stepped control of heat output; it does not contain temperature âsensing or thermostat feedback. When assessing compatibility, compare the electrical ratings, number and layout ofâ spade terminals, shaft diameter and lengthand mounting bushing or bracket orientation – âdifferences in any of these can preventâ a direct â¤swap even if the part number appears similar. For example,a replacement âmust match âthe terminal spacing⢠and tab size âused by the oven harness to âŁavoid âloose connections or â¤arcing,and the shaft profile must alignâ with the âcontrol knob indexing toâ ensure accurate position selectionâ across âŁthe full range.
Replacement and installation require verification of both electrical and mechanical fit before re-energizing the⤠appliance. De-energize the appliance, document wiring⤠locations (photograph if helpful)and⤠confirm continuity and expected resistance ranges across terminals with a multimeter â˘to identify open circuits or shorted âelements prior to installation. âAfter installing a matched â¤unit, secure âmounting hardware to⣠avoid mechanical â¤stress âŁon terminals, restore power briefly âto⤠cycle through settings and observe smooth transitions without overheating,â arcing, â¤or smoking;â if any abnormal behavior appears, remove power âand re-check connections. Practically, also inspect the oven harness insulation and connector âŁtabs âfor corrosion – replace theâ harness if tabs are loose or terminalsâ showâ signs of âmelting.
- Power off and photo theâ wiring before disassembly.
- Match terminal count, tab size, shaft typeand âmounting bushing to âthe old switch.

Q&A
What is⣠the WB24T10029 infinite switch and what does it control?
The WB24T10029 is a ârotary â”infinite” control âŁswitch⤠used onâ many GE ranges/cooktops⢠to select⤠the power level of a surface burner. âIt mechanically â¤connects different internal⣠taps to the burner âcircuit as you turn⢠the knobâ so â¤theâ element receives âdifferent portions of the â¤supply voltageâ or different cycling patterns, producing variable heat âsettings⢠from low through high.
what are the âŁcommon symptoms that âindicate âthe WB24T10029 has failed?
Typical âsymptoms includeâ a burner âthat won’t heat at any setting, a burner that only⤠works on one or two âsettings (such â˘as only high), intermittent heating, a⢠knob that turns without changing element â˘output, âŁvisible burning â¤or âmelting at theâ switch, âor a switch âthat âŁfeels rough or loose. Always rule out a⣠bad element,wiring,or terminalâ connection first.
How do I safely test⢠the âWB24T10029 with a âŁmultimeter?
Safety first:⣠disconnect power at the breaker or unplug the appliance. Remove the knob â¤and access the switch. Photograph or â¤label each wire â˘before âdisconnecting. Using aâ multimeter setâ to continuity/ohms,check for continuityâ between the⣠common/line terminal and â¤the â˘element terminals while rotating theâ switch⣠through positions. In OFF you â˘should see open to theâ element terminal(s); asâ you move âtoward higher settings continuity should appear on one or more âelementâ terminals. If you get no continuity in any position⤠(and the element is known good) theâ switch is likely faulty. Do not perform live voltage tests unless you are qualified; live testing requires strict safety procedures.
How can I tell if⢠the⤠problem is the switch or the burnerâ element?
Test⢠the elementâ first by removing it and measuring its resistance for continuity (a⤠good⣠element will show a low resistance path, not â¤an open circuit). If⤠the element checks good and wires/terminals âare intact, test theâ infinite switch as described above.⤠Also visually⢠inspect connectors for â¤burning or loose âterminals. If the âelement is open, â˘replaceâ the element; if the element â˘isâ fine and the switch shows no proper âcontinuity⤠across positions, âŁreplace theâ switch.
Can I replace the WB24T10029 myself and what â˘is⣠the installation process?
Yes, a âŁcompetent âDIYer⣠can replace it. Steps:⣠turn off âŁpower at the breaker,â removeâ the control panel/knob to â¤access the âswitch, takeâ a photo or label wires, disconnect the spade connectors, remove mounting screws, install the new⤠switch, reconnect wires â˘to âthe same terminals, reassemble âand ârestore power. âUse the exact OEM part number or â˘confirmâ compatibility. If you are not comfortable working with mainsâ wiring, hire a qualified technician.
How doâ I confirm WB24T10029 is the correct replacementâ for âmy GE range?
Confirm by checking your appliance model⣠number â¤(usuallyâ on a⣠tag behind the storage drawer, oven door frame⣠or rear â˘panel) andâ cross-referencing it with the OEMâ parts list or âa âreputable âŁparts â¤supplier.â Order â¤by âthe exact part number (WB24T10029)⤠or use the manufacturer’s compatibility chart. If in doubt,contact GE/Frigidaire parts or âan authorized dealer with your⢠model number.
What do the switch⤠terminals mean and do wire colors matter?
Terminal âŁdesignations differ by manufacturer but⢠common labels âŁinclude L1 (incomingâ line/hot), âŁH1/H2 or terminal(s) to the burner elementand a terminal forâ an indicator light or pilot.Wire âŁcolors are not â¤standardized across all âmodels, so do not relyâ solely on âcolor when reconnecting; always match each âŁwire to⢠the correct terminal using your âphotos, labelsor âthe wiring âdiagram in⣠the âŁserviceâ manual. If terminalâ labels areâ present âon the â˘part,⢠reconnect â˘by label rather than⢠by color.
Howâ much does a âWB24T10029 replacement usually âcost and are aftermarket âparts â¤OK?
Pricing varies, but the part typically ranges from about $20 to $80 depending on supplier and whether it âis⣠OEM.OEM â¤(GE) â˘parts are recommended for best fitâ and reliability. Some aftermarket or âŁworldwide infinite âswitches may work,but ensure â¤electrical ratings,terminal layout,mounting,and control detents match your original switch before⢠using⣠them.
