WB24T10153⤠GEâ Oven â˘Infinite Switch Control is a rotary power-control assembly used on many General Electric electric ranges and ovens.Theâ part is â˘an “infinite” â(continuously variable) switch that modulates âthe⣠amount of lineâ powerâ supplied to â¤a heating⤠element â¤by varyingâ the on/off duty cycle as the user adjusts⢠a knob; mechanically it⤠comprises aâ selectorâ shaft,⤠internal contact â˘wipersand terminal connectionsâ andâ is mounted behind the âcooktopâ or controlâ console.
Within the appliance,the infinite switch serves as the user-facing power regulator for â˘a specific heating circuit and â˘directly interfaces wiht the heating⢠element,supply wiring and,on some â˘models,indicator lamps or⢠theâ main control⤠board. It⤠does not function â˘as a temperature sensor or thermostat âbut instead â¤provides stepped or variable power levels âtoâ achieve different heat settings. Because the switch âcarries full line âŁvoltage âand switching âcurrent, â˘its⣠contact condition, electrical⢠ratings and mounting âŁaffect both performance and safe operation of the cooktop or oven circuit.
In this⣠article youâ will find technical coverage â˘of how the WB24T10153⢠operates, âthe electrical â¤and mechanical characteristics relevantâ for compatibility, common failure symptoms â(for example noâ orâ intermittent heat, aâ burner⤠that⣠isâ stuck â¤on or offor visible contact damage), approaches âto isolate⤠switch faults from element or wiring problemsand practical replacement considerations including⢠matching terminal layout and ratings.

Function and Role âof the Infinite Range Switch in GE Electric Ovens
The WB24T10153 â¤GE Oven Infinite Switch Control is aâ stepped âpower selector that regulates the âamount of mainsâ power delivered to an oven â¤heating â˘circuit âby varying the on/off âduty cycle rather âthen âproviding a âcontinuously⢠variable voltage. Inside the control,aâ rotary âselector operates a âcam and set âof contacts⣠(andâ in some designs an â˘internal thermostat⢠or bimetal element) to change the proportion of time the element is energized; âthis producesâ reliably⣠repeatable heat settings across low-to-high ranges. The switch must match the oven’s electrical â˘characteristics and mechanical interfaces-terminal âconfiguration, voltage/current rating, shaft âlength and diameter, âand mounting pattern-to ensure⣠proper operation and safe replacement.
In âpractical⢠use the infinite switch modulates â˘heat during âŁpreheat and⢠steady-state temperature â˘control: larger duty cycles supply more heat⢠duringâ rapid warm-up, while reduced duty âcycles maintain a setpoint without⣠overheating.â Common failure modes include open contacts (no heat), welded âcontacts (continuous heat), â˘intermittent contact (erratic cycling)and increased â˘contact resistance â(reduced element power). Technicians diagnose faults by observing symptom behavior underâ load and by measuring continuity and voltage âŁat the switch terminals across selector positions; replacement requires a part with equivalent electrical ratings and matching terminal layout to avoidâ miswiring or heat-control⤠errors.
- Function: variable duty-cycle control of oven â˘heating circuits viaâ mechanical selector and contact stack
- Common⤠symptoms âof failure: no heat, constant heat, â˘erratic cycling, â¤or inability to reach/hold set⤠temperature
- Diagnostics: continuity checks per position, voltage measurement to element under âload,⤠visual inspection of contacts
- Replacement â˘criteria: match terminal layout, voltage/current rating, â¤shaft sizeand âmounting⢠style

How the WB24T10153 GE Oven Infinite â¤Switch Control Works Inside the â¤Appliance
The WB24T10153 GE Oven âŁinfinite â˘Switch Control is a âŁrotary power control that âmodulatesâ the amount of electrical âenergy âdelivered to the oven’s heating element by varying the on/off duty âcycle as the user⤠turns the temperature or power âknob. âInternally the âŁswitch â¤uses⤠a cam or resistive⤠assemblyâ and a moving contact (wiper) to change the proportionâ of âtime the element sees full lineâ voltage; âŁat low settingsâ the contact closes briefly⤠and âat higher settings it closesâ for progressively longer intervals. In normal operation the⢠device does not provide a continuous variable âvoltage but rather âcontrols âaverage power through âŁtimed switching, so â¤measurements taken withâ a⢠multimeter should be âŁinterpreted as âpulse duty rather than â˘steady intermediate⢠voltages.
Technically, âthe â¤part âis mounted in the â¤oven control cluster and⤠interfaces between the incoming âŁline, the⣠thermostat or control board,â and the bake/broil elements; replacement requires matching terminal configurationâ and â¤mounting footprint to ensure correct wiring and thermal â˘sensing. for troubleshooting, verify continuity across the appropriate terminals with⣠the âswitch âin multiple positions and observe element cyclingâ under âlive conditions (with proper safety precautions) to⤠distinguish aâ failed infinite switch from a separate thermostat or wiring⢠fault.⤠Technicians âŁshould use the âcorrect OEM part number for compatibility toâ avoid mismatched terminal layouts or differing⢠camâ profiles that⢠change the control’s behavior.
- No âheat or âintermittent heating under any knob âposition
- Oven runs continuously âat full power â¤regardless of âŁknob â¤position
- Temperature changes âdo ânot⢠correspondâ to⣠knob position or are erratic
- Visible arcing at switch âterminals orâ burnt/meltedâ terminalâ insulation

Common Failure Symptoms andâ Diagnostic Indicators of Infinite Switch Faults
The WB24T10153â GE Ovenâ Infinite Switch Control regulates variableâ power to the oven’sâ heating element⣠by switching contact positions as the âcontrol knob moves âthrough itsâ range. When this infinite switch begins âto â˘fail,its contact assemblyâ can stick,burn,or developâ intermittent âconnectivity,producing symptoms that mimic thermostatâ or element faults. Such as, a working bakeâ element that never reaches setâ temperature⤠while the thermostatâ and âŁelement âtest good frequently âŁenough points toâ the infinite switch failing to âŁprovide full power; âŁconversely, an oven⣠that runs excessively hot or cycles erratically âcan indicate⤠contacts that are âshorting or failing toâ make consistent, graded connections. Compatibility-wise,â the WB24T10153 must match â˘the oven’s âterminalâ layout andâ electrical ratingsâ – mismatched replacements can âproduce incorrect⣠behavior even if mechanically similar.
- No heat⤠at âany setting âdespite a good heating â˘element
- Oven overheats or ignores âset⢠temperature ranges
- intermittent âheating or âon/off cycling unrelated âto⤠thermostat calls
- Knobâ positions⣠that do not âŁcorrespond to expected heat output
- Audibleâ arcing, burning smellsorâ visible scorching at the switch housing
Diagnosing the infinite âswitch focusesâ on electrical continuity,â visual inspectionand âlive-voltage verification with the thermostat calling for heat. Use a multimeterâ to check for continuity between the âcommon âand output terminals while rotating âthe knob; a⢠functioning control will show a âsmooth change âin resistance or a predictable change in continuity corresponding to knob âŁposition, whereas âan open â¤circuit⤠or wildly â¤erratic readings indicate⤠internal failure. Visually inspect terminals for discoloration, melted insulation, â˘or pitted contacts, âŁandâ perform a controlled live-voltage test (with power disconnected after marking terminal positions) to â˘confirm correct switching under load. When measurements deviate from the values listed in âthe⤠appliance service manual or when physical damage is present, replacing the control with a correctlyâ specified WB24T10153⣠GE Oven Infinite switch Control is the practical remedy rather than attempting contact⢠cleaningâ or temporary wiring fixes.
| Item | Description |
|---|---|
| No heat | Open circuit on output terminal or failed contact-multimeter shows infinite resistanceâ when⤠knob is âon heat position |
| Overheat/Short cycling | Contacts partially shorting or sticking; voltage present continuously âorâ toggling improperly âduringâ knobâ sweep |
| Visible damage | Discoloration,â pitting, â˘or melted â˘plastics⤠at terminalsâ indicating thermal/arc failure |
Replacement Considerations and Installationâ Procedure for WB24T10153 âŁGE Oven Infinite Switch Control
WB24T10153 GE Oven Infinite Switch â¤Control is an âŁelectromechanical controlâ that regulates power to the oven heating âŁelement by switching line voltage⢠on âand off â¤at varying dutyâ cycles to âproduce variable âheat settings. Technically, the device contains â¤a rotary selector and a set ofâ contact cams⣠that changeâ theâ on/off⢠ratio âŁas the knob position changes; this produces a stepped,â average power⤠output⣠rather than âa smooth analog voltage. When evaluating a replacement, compare⣠the â˘oldâ switch’s terminal⤠layout, mounting earâ spacing, shaft diameter andâ length, âand⣠the stamped electrical âratings on âthe part. â˘Cross-referencing the OEM⤠part⣠number and visuallyâ matching terminals and mounting features prevents common mismatchesâ such as reversed â¤terminal order or âŁincompatible shaftâ geometry that â¤will impede installation âor âoperation.
Installations require⤠basic âŁelectricalâ safety and a methodicalâ approach: de-energize the appliance at⢠the breaker, remove the control knobs and access â¤panel, document or label each wire to the existing switch, âand⢠carefully transfer leads to the corresponding terminals on the new switch. After⣠mechanical mounting andâ hand-tightening fasteners, restore power âŁonly for â˘functional testing: verify â˘knob positions âproduce expected element cycling and use⢠a multimeter toâ confirm continuity changes across âcontacts as the selector is rotated. If the âswitch⢠controls both âbake and broil circuits, test âŁeach circuitâ individually â¤at low, medium and high settings;â inspect terminal crimps for secure connections and avoidâ bending tabs or over-torquing â¤mounting screws wich can distort the⢠switch⤠housing and cause premature failure.
- Safety first: â¤disconnect mains before any wiringâ workâ and verify no â˘voltage present with a meter.
- Label âor photograph â˘wire⣠positions before removal âŁto ensure âcorrectâ reconnection.
- Match terminal count and⤠arrangement rather âthan assuming wiringâ colors are identical⢠across â˘models.
- Use aâ continuity check through the selector positions to confirm correct operation prior to⢠reassembly.
- Inspect insulationâ and replace any frayed âleads or damaged âpush-on⤠terminals during âinstallation.

Q&A
What is the WB24T10153⤠infinite âswitch and what does it⢠control?
The WB24T10153â is an⢠OEMâ rotary “infinite” surface element switch usedâ on many GE/Hotpoint electric ranges âand âcooktops.It controls â¤theâ power delivered âto a surface heating elementâ by switching âthe element âon and off âin different duty cycles as you rotate⣠the knob, producing â˘variable heat âsettings â˘from low to high.
What are common signs theâ WB24T10153 switch has failed?
Common symptoms include a burner that will not heatâ at â¤all, a â¤burner⢠that âis âŁstuck on full heat, only some âŁheat settings working, an indicator light that behaves incorrectly, visible burn marks/ arcing at the switchor intermittent operation. Anyâ of thes justify âinspecting⣠or âreplacingâ the switch.
how do âI safely test the âinfinite âswitch⣠with a⣠multimeter?
Turn off power at the circuit breaker and verify voltage is absent.â Remove the knob andâ access the switch, photograph or⣠label âŁwires first. â˘Inâ ohms mode, check for continuity between the power (common)â terminal and the element/load terminal while rotating the knob⣠– continuity should increase asâ you⣠move from OFF toward HIGH. âAlso check for no continuity (open) between any terminal â¤and ground/chassis. Ifâ the switch does⣠not change continuity acrossâ positions or showsâ a short⢠to ground, itâ isâ indeedâ likely defective. If you are not agreeable with electrical testing,â hire a qualified technician.
Can I repair the WB24T10153 âŁor should⣠I âŁreplaceâ it?
Theseâ switches are not âgenerally serviceable or repairable at component level; they are inexpensive replacement⢠parts and should be replaced as âa âunit if faulty. âReplacing with the correct OEM âpartâ number (WB24T10153) â˘isâ the â˘recommended approach.
How do I replace the WB24T10153 infinite switch?
Safety first: disconnect âpowerâ at the⢠breaker. Remove the knob and the control panel or⢠lift the âcooktop as required to access the switch. Photograph and label all âwire connections. Pullâ off the spade connectors â(use needle-nose pliers if âneeded), remove âmounting screws, swap the old switch âfor the new one, reinstall screws, reconnectâ wires to the matching terminals, replace â¤coverings and restore power. Test âeach burner.If wiring terminals areâ corroded or different, consult the range’s wiring diagram.
Is it normal for the â¤burnerâ to cycle⤠on and off âwhen â˘using â˘this switch?
Yes. The âinfinite switchâ regulates âheat by cyclingâ power âŁto the element (varying⢠duty cycle). âYou may notice the element pulsingor an indicator light â˘turning âon/off asâ the switch cycles – this is normal behavior. Continuous⢠full-power heat (no cycling) can indicate a stuck switch or â˘another fault.
Could something else besides the infinite âswitch cause the same problems?
Yes. Surface element failure, element terminal block, âloose or burned wiring, âor a fault in the range’s wiring harness or controller can cause similar symptoms. Alwaysâ inspect âthe âelement and connections and⣠rule out wiring⢠issues before⣠assuming the switch is⣠the only cause.
Where âcan I get⢠the correct â˘replacement and how⢠do I confirm compatibility?
Buyâ OEM â˘WB24T10153 fromâ GE/Hotpoint parts suppliers,reputable appliance parts stores,or authorizedâ dealers. confirm compatibility by checking your appliance model number and the partâ cross-reference; compare terminal âŁlayout and mounting âŁbefore installing.Avoid âcheap nonâmatching substitutes – wrong terminal spacing or⢠ratings can cause malfunction or safety hazards.
