Function⤠and Role of the âOven Burner Infinite Switchâ in⣠Power and⢠Temperature âControl
The WB24T10029 GE Oven Burner Infinite Switch is aâ rotary power regulator that⢠provides continuously variable control of the oven âheating â¤element by selecting between resistive taps and modulating the on/off duty cycle. It â˘does âŁnot âŁmeasure oven temperature â¤itself;â rather, it converts aâ user-selected position or âa control signal into proportional electrical⣠power âŁdelivered toâ the burner. The device combines stepped resistance paths with timed â¤switching so that lower âsettings reduce current byâ adding resistance or⤠shortening â˘on-time, while higher âsettings reduce series resistance and increase âduty⢠cycle, âŁproducing smootherâ power âtransitions than a simple single-contact âswitch.
- Function: continuously varying power output via stepped resistance and⣠duty-cycle modulation
- Interfaces: connects between oven control/thermostat âand the⢠heating element;⤠layout â˘and terminal labeling âmust match theâ appliance
- Behavior: provides proportional heat controlâ rather thanâ direct temperature regulation
- Common failure symptoms: no heat, âstuck-on element, intermittent or âŁunevenâ heating at certain settings
Technicians should verify mechanical⢠fit, terminal arrangementand voltage rating before substituting this⤠part; âan exact match or approved cross-reference âŁis required âfor safe operation. Diagnostic checks include continuity and resistance measurements across âthe common and load terminals in multiple knob positions and observing the element’s⣠on/off behavior (with appropriate safety precautions) to confirm changing duty â˘cycle.When replacing the unit,â confirm âthat âŁthe switch’s mounting, âŁactuator lengthand terminal types correspond to the appliance wiring harnessâ to avoid miswiring or improper heat control.

How the WB24T10029 GE Oven Burner Infinite Switch Works Inside the âŁAppliance: Internal Components, Contacts,⣠and Electrical Pathways
Theâ WB24T10029 GE Oven Burner⤠Infinite âSwitch is a rotary âŁcontrol that regulates surface burner heatâ by mechanically routing power âŁthrough âan âinternal resistive track, movable wiper/contact assemblyand a temperature-sensitive interruptor. Inside the âassembly you will findâ a shaft⢠and cam âŁthat position the wiper overâ a resistive element toâ vary âthe⤠portion ofâ the AC waveform applied âto the âburner, stationaryâ brass terminals for line and â˘load connectionsand aâ bimetallic or⣠thermal cutout element that cycles theâ circuit on and off at low settings to achieve â˘lower average power. In practice this means the electrical pathway runs âfromâ the incoming line terminal,â through the⢠resistive/wiper network and any⤠series contactsand then out toâ the burner element; at higher settings the wiper â¤presents a near-direct path with lower resistance and less âcycling, while âat lower settings⤠the â˘bimetal opens more frequently to reduce duty cycle andâ average powerâ to theâ element.
- Common internal parts: shaft/cam,â wiper/contact, resistive âtrack, bimetal/thermal cutoffandâ screw⤠terminals.
| Item | Description |
|---|---|
| Wiper/Contact | Sliding conductor that⢠changes the resistance path â¤to the burner contact as the knob rotates. |
| Resistive Track | Element that creates variable voltage drop across the burner â˘circuit for âintermediary settings. |
| Bimetal/Thermal Cutout | Cycles the circuitâ at low settings to reduce average powerâ and provideâ temperature-limitedâ interruption. |
| Terminals | Brass posts â¤labeled for line,load,and neutral; must matchâ harness layout for âcompatibility. |
Fromâ a diagnostic and compatibility â¤standpoint, technicians verify switch âbehavior by⣠measuring⤠continuity and observing cycling across â¤specific terminals: at the maximumâ setting there should be solid continuity âŁbetween the line and âburner output terminal, while at âlow settings the tester will see intermittent â˘continuity consistent âwith bimetal cycling and increased resistance⤠through the track. Visible contact pitting, burnt terminals,⤠or a seized wiper commonly produces intermittent or âŁstuck-on behavior; replacing the unit⣠with a correctly numberedâ WB24T10029 GE Oven Burner â¤Infinite Switch or an approved cross-reference requiresâ confirming terminal layout, âmountingâ footprintand expected â˘resistance â¤profile to ensure safe, reliable operation. â¤Always disconnect mains power âbefore bench-testing andâ compare âmeasurements toâ known-goodâ values to determine whether the switch orâ the burner element is âat fault.
Common Failure Symptoms and⣠Diagnostic Indicators for the oven burner Infinite Switch
The WB24T10029 GE Oven â¤Burner Infinite â¤Switch is â˘theâ user-accessible rotary control that modulates⢠power to â¤the oven burner by⢠switching the⤠line âŁvoltage on and off in variable duty cycles. Failures of⢠this part typically present as âloss of heat, a âburner that remains âat a single⤠temperature regardless of â¤knob position, rapid cycling that⢠prevents the oven from reachingâ set âtemperatureor audible arcing fromâ the control area. âbecause âthe⣠infiniteâ switch is a mechanical contact assembly, commonâ root causes include worn âor⣠pitted contacts, carbon tracking â˘onâ the â¤housingand melted⤠insulation on terminals; thes⤠lead â¤to increased contactâ resistance, intermittent connection,⤠or a permanent short. Confirming â˘the part number⢠WB24T10029 GE Oven Burner⣠Infinite Switchâ against theâ appliance model and terminal layout before replacement â˘reduces compatibility issues duringâ repair.
- No heat or â¤poor heat âcontrol at any⤠knob setting
- Burner stuck at high or⣠low âŁoutput â¤/ single fixed â˘setting
- Intermittent â¤heating that correlates with knob movement or physical tap
- Visibleâ arcing, discoloration,â meltingor burnt smell at the terminal block
For diagnostics, first disconnect mains power, then perform a continuity check⢠across⢠the switchâ terminals while â˘rotating theâ shaft through its range: a healthy contact reads near⢠0â Ί in closed âpositions and âshows open circuit in positionsâ that⤠should be open.⤠High but finite resistance (hundreds of ohms or variable readings) under static test suggestsâ pitted or oxidized contacts and corresponds with intermittent heating⣠under load; in-situ âvoltage checks (with powerâ applied by âa trained technician) willâ show a pulsed supply âŁto âthe heating element if theâ switch⣠is modulating correctly.Physical inspectionâ for pitting,carbon âŁtracking,or softened plastic,and a wiggleâ test for âintermittent continuity,are practical indicators that the switch requires replacement rather than further adjustment.
| Item | Description |
|---|---|
| Continuity (closed position) | Near 0â Ί (low resistance) |
| Continuityâ (open position) | OL / infinite â(no âŁcontinuity) |
| Visual condition | Pitting, carbon tracking,⤠melting or discoloration indicates⣠failure |
Replacement Considerations, Model âCompatibilityand Installation Best â¤Practices

Q&A
What isâ the WB24T10029 infinite switch⣠and what does it control?
The WB24T10029 is⤠an âinfinite (rotary) control switch used on GE ranges to regulate the heat output of a surface/ovenâ burner (typically a cooktop âcoil).â It does not âŁprovide a single fixed ânumber â˘of steps but varies the duty â˘cycle⢠of power to the element⣠as you turn the knob, producing a range â¤of heat â¤settings from low to high.
What are common symptoms that the WB24T10029 âhas failed?
Typicalâ symptoms include: a âburner⤠that âonly works on high⤠(or only on low), a burner that won’t heat at all, intermittent operation, a knob that clicksâ or sparks, visible burning or melting at the switchor erratic temperature control.⤠Any of these indicate the âswitch â˘may be worn or⣠the internal contacts â¤are âdamaged.
How can I test the infinite⣠switch safely with a multimeter?
Always disconnect power atâ the circuit breaker before testing. For⣠continuity tests, âremove the⢠switch from theâ appliance⤠so you can â¤access terminals. With the meter on continuity/ohms, check forâ continuity between the âŁcommon â(input) terminal and the selectable output terminal(s) while âŁrotating the knob through âsettings; âyou should see the connection make and break âas the cam cycles. Also check for shorts to ground (infinite resistance⤠between terminals⤠and chassis). If you âneed to check live voltage, only do so if qualified: verify proper â˘supply âvoltage to theâ switch (and voltage out to the element in selected positions) âŁand be cautious-isolateâ power first and use insulated probes if testing live.
What is the correct procedure⢠to replace the WB24T10029?
Turn off and lock out power at the â¤breaker. Removeâ the âŁcontrol knob and⤠access the switch â˘through the back of the control panel or under the cooktop (follow your âmodel’s⣠service instructions).⢠Photograph or label wiring â˘before disconnecting. â˘Remove mounting screws and disconnect wires from the terminals (use needle-nose pliers or a⤠terminal puller). Install the new switch,reconnectâ the wiresâ to the same terminals,secure the âŁswitch,reassemble the âŁpanel,restore power,and test the âburner function. If unsure, have a qualified technician perform the replacement.
How⣠do I know âif WB24T10029 is the âcorrect replacement part for my range?
Verify âcompatibility by⤠checkingâ your⤠appliance model number⣠(usually on a tag behind the oven doorâ frame, on âthe frameâ of the cooktop,⤠orâ inside the storage drawer). Cross-reference âthat model number with GE parts lists or⤠a trustedâ parts supplier to⣠confirmâ WB24T10029â fits your range.⣠Also compare mounting style,â knob shaftâ diameter, terminal layoutand electrical ârating printed on âthe switch toâ ensure âŁit matches.
Can the switch â¤be repaired or should it be replaced?
Infinite switches areâ not â˘generally ârepairable-internalâ contactsâ wear⢠and plastic â˘components can âdeform from heat.Cleaning external corrosion on terminals may help â˘in rare cases,but for intermittent⤠contact,arcing,or⣠mechanical wear,the â˘correct action âis replacement with the proper OEM âpart.
What â¤causes the WB24T10029 â¤to fail prematurely?
Common causes include heat and age-related⢠wear of the contact surfaces, â¤arcing âfrom high current draws,⣠moisture or food spills that corrode âterminals, physical âŁdamage from forceâ on the âŁknoband electrical surges.⣠Repeated high-load cycling âŁand poorâ contact seating accelerate contact pitting and failure.
Before⢠replacingâ the âswitch, what troubleshooting should I do to confirmâ the âswitch is the problem?
Confirmâ the burner element itself⤠is good by checking its continuity and resistance; inspectâ the element for âŁvisible damage. Verify wiring âand terminal block connections are intact⣠and that the switch is receiving supply voltage â(with power off, check wiring continuity; with power on only ifâ qualified, check voltage). Swap withâ a known-good compatible switchâ if available or âtest theâ switch out of âthe appliance for proper continuity behavior through knob positions. if theâ element â˘andâ wiring⣠are âOK and the switch behaves⢠erratically,replacement⣠is â˘warranted.
