WB24T10027 GEâ Oven⢠Range⤠Cooktop Top Burner Infinite Switch 2100W is an electromechanical âŁrotary power âcontrol â¤designed for âuse on âthe surface burners of GE electric âranges and cooktops. The device is an “infinite”⣠or multi-positionâ switch that⤠controls the amount of electrical power delivered to a surface heatingâ element across a range of âsettings by varying duty cycle and⢠contact configuration; the 2100â W rating indicates the maximum elementâ power for which the⢠switch isâ specified under nominal supply âŁconditions.
Inside the appliance the infinite switch functions as the user-facing⢠control⢠nodeâ between the range’s control knob andâ the burner element, routing line â˘voltage to the element terminals⣠in timed cyclesâ to produce âlowâ through high heat âoutput. It â¤typically mounts behindâ the⤠cooktop control panel and â¤interfaces with â¤the⣠burner element, the wiring harness/connector block,â and any indicator lights or thermal cutouts âin the cooktop âŁassembly. Technically, theâ unit provides â¤multiple terminal connections (common, high, low, âandâ often a pilot âlamp terminal), must carry the appropriate⣠current for theâ element wattageand withstand switching âstresses and heat exposure⤠common to cooktop environments.
In âthis article you will find aâ technical âŁoverview â˘of the infinite â¤switch’s operating principle,⢠guidance on compatibility and how âto âŁconfirm the correct⤠replacement âŁby⢠part number, terminal layout and⤠power rating, common âfailure symptoms to â¤look for (no âheat, stuck-on heat, loss of intermediate settings, intermittent⤠operation, visibleâ contact damage), practical troubleshooting steps â˘(continuity and resistance âŁchecks, voltage verification at the switch with the control operated, inspection of⢠connectors â˘and element continuity)and âŁsafe replacement considerations (power isolation, matching wattage/voltage and terminal configuration,⢠physicalâ mounting andâ insulationand⤠basic post-replacement verification).

Function and role of â¤the Cooktop Top â˘Burnerâ Infinite⤠Switch in GE Electric Ranges
The WB24T10027 âGEâ Oven âRange Cooktop Top âŁBurner⢠Infinite Switch 2100W âis aâ rotary âŁpower control that regulates⤠the current delivered to⣠a surface heating element. It does this⤠through a cam-driven contact â˘assembly and internal resistive/cycling⤠network that provides â˘a continuous range of heat settings: lower knob positions produce⢠periodic on/off cycling to reduce average power, while higher settings provide near-continuous current â¤up to⢠the switch’s rated 2100W. The⤠switch exposes several terminals (commonly labeledâ L1, L2 or neutral, element outputand an indicator lamp terminal) andâ must match the cooktop element’s wattage and terminal configuration for safe, âcorrect⣠operation.
- Function:⣠variable powerâ control âvia cam contacts⢠and cycling mechanism
- electrical rating: 2100 watts maximum for the topâ burner circuit
- Terminals: line(s), element output,â and lamp/indicator terminal (verify layout before replacement)
- Common symptoms of failure: noâ heat,â burner stuck on, intermittent heating, arcing or visible burn marks atâ terminals

Disconnect âpower before âtesting orâ replacing the switch. For â˘field diagnosis,a⤠technician â¤should⤠confirm line voltage atâ the âL1/L2 terminals,use an âohmmeter to track⣠continuity âthrough âthe⣠element output terminal â˘across knob positions,and inspect for burned contacts⣠or loose spade connectors. In service or⣠replacement scenarios, matchâ the physical mounting, terminal arrangementand the 2100W rating; usingâ the exact âpart or a⣠documented equivalentâ preserves heat control behavior and â˘reduces⤠the risk of overheating âor nuisance failure.
How the WB24T10027 âŁGE Oven âRange â¤Cooktop Top Burner Infinite Switch 2100W Works Inside the⢠Appliance
The⢠WB24T10027 GE Oven Range Cooktop Top Burner Infiniteâ Switch 2100W âis a â¤rotary, time-proportional control that regulates the surface elementâ by varying the applied power ârather thanâ providing a fixed number of discrete⣠steps.Internally the switch alternates connectionâ between the hot leg and âthe âelement⣠through a cam and âcontact assembly combined with a small⣠heater/bimetal⤠or electronic timing mechanism to âcreate a duty cycle that yields intermediate heat settings. At the highest setting the switch⢠provides continuousâ application of up toâ 2100 watts (typical for âmany 6-8″ surface elementsâ on 240⤠V circuits), â˘while lower positions reduce the effective on-time âŁto achieve simmer and medium âheat levels without modulating element resistance⣠itself.
Technicians should verify compatibility by âmatching the âmechanical âshaft, mounting footprint, terminal layoutand power ratingâ to⢠the⤠cooktop element and wiring harness; âŁincorrect wattageâ or terminal⤠miswiring can produce weak heat, overheatingor cycling faults.Common failure modes include burnt or pitted contacts causing⣠intermittent operation, âŁa âstuck cam that leavesâ the elementâ at a single outputor âaâ failed timing/heater assembly âthatâ prevents proper duty cycling. Typical diagnostic steps include checking forâ continuity across â˘the line/load terminals withâ the control â˘set â˘to different positions, â¤confirming full â¤supply voltage at⤠the⢠switchand substituting a known-good⢠element or⣠switch to⤠isolate the fault.
- Symptoms: no âheat at any setting,only âŁhigh heat,or only low heat/cycling.
- Checks: verifyâ correct 240 V â¤supply, inspect terminals for corrosion, measure continuity â˘and âŁresistance across contacts.
- Replacement advice: match wattage⣠rating âŁand⣠terminal arrangement;â secure connectors to prevent arcing.

Common Failure Symptoms, âElectrical Test â˘Points and âDiagnostic Measurements forâ Infinite â˘Switches
The WB24T10027 GE â¤Oven⣠Range Cooktop Top âBurner Infinite Switch 2100W is a rotary, multi-position contact⣠assemblyâ that âmodulates âpower to âa⤠2100 âŁW surfaceâ element by switching theâ element âon and off with varying â˘duty⢠cycles rather thanâ providingâ a variable resistance. In⣠practice âŁthis âpart replaces âthe manual âŁcontrol⤠and delivers⢠stepped heat settings by using internal contacts and a bimetal/timing â¤mechanism to â¤interrupt⤠line âŁvoltage to the element. On compatible GEâ ranges⣠designed for a 2100 W top burner,the element resistance will âbe approximately 27.4 Ί at 240 V (resulting in about â˘8.75â A),â so diagnostic âwork should treat the infinite âswitch as a cycling contact âdevice and âverify âŁboth contact integrity and correct on/off behavior under load rather than â¤looking for a linear resistance value inside âthe switch itself.
- No heat or intermittent heat despite correct supply â˘voltage (open â¤contact inside switch or bad timing âmechanism).
- Element⣠remains onâ at all settings (stuck contact or welded âcontact surfaces).
- Rapid cycling, âŁarcing âor visible pitting at the switch terminals âŁ(contact wear or contamination).
- Knob â¤positions do not change heating behavior or provide onlyâ oneâ fixedâ power âŁlevel â¤(bimetal/timer failure).
For electrical âdiagnosis, âŁremove powerâ and perform âcontinuity and resistance checks: verify continuity between the line and switch common terminal, âthen between âŁcommon and the load terminal while âŁactuating â¤the control or rotating âthe shaft to âthe high setting; a good closed contact willâ show very low âresistance (<⢠2 â¤ÎŠ)â while open should âshow no âcontinuity. With the element⢠connected⣠and the â¤appliance powered (use⣠caution and follow âlockout/tagout rules), measure⣠AC voltage at the switch â¤load terminal: voltage â˘should âappear equal to line when â¤the internal contact is â¤closed⢠and drop toâ zero â¤when open, reflecting the âŁswitching duty cycle âratherâ than aâ partial voltage. âAlso measure the element âresistance directly to distinguish a failed element âŁfromâ a â˘switch fault; if the element⣠reads nearâ the expectedâ value (around â27.4 Ίâ for 240 V, 2100 W) and the âswitch proves open at a â¤setting that should supply power,⢠theâ switch⣠is the likely⤠cause.
| Item | Description |
|---|---|
| Expected elementâ resistance (240 V) | Approximately 27.4 â˘ÎŠâ (240² / 2100 W) |
| Expected current (240 V) | About 8.75 A (2100 âŁW / â˘240â V) |
| Closed contact âresistance | Typically < 2 Ί; considerably higher indicates worn contacts |
| Open condition | No continuity â˘(OL) â¤betweenâ line and âŁload â¤with switch⣠in OFF âŁposition |

Q&A
What is âŁthe WB24T10027 infinite â¤switch and what does the 2100W rating mean?
The WB24T10027 isâ an infinite control (infinite switch) used on â¤GE-style âŁelectric⢠cooktop top burners âŁto vary âtheâ heatâ ofâ a surface element.â The 2100W rating indicates âthe⣠maximum wattage âof the element it is designed to control (commonlyâ a 6″ or 8″ âsurface element). At 240 volts⢠this corresponds to aboutâ 8.75 amps (2100W á 240V). You should use⣠a switch rated at the same wattage/voltage⢠as the element to avoid overheating âor premature failure.
How âdo I âknow if⢠the infinite switch is bad?
Common â˘symptoms of a failing infinite switch include: the âburner won’t heat⢠at any setting, the burner â¤is⣠stuck on a single setting (usually âhigh), theâ burner âonly works on some settings, âintermittent operation, âor excessiveâ clickingâ whenâ you turn⢠the knob. Confirm the element⢠itself and âthe wiring are âŁgood before replacing the switch. Also âinspect for âvisible damage, âŁburningor⤠melted terminals.
Can I testâ the âŁWB24T10027 with a multimeterand what should I measure?
Yes. First disconnect âŁpower at âthe breaker â¤and removeâ the knob and âswitch from the cooktop. With âthe⣠switch⢠disconnected, use the⣠ohms function on âyour multimeter. Typical â¤checks:⢠atâ the “Off” position âyou should see an open âcircuit âbetween⢠the load terminal and â˘the lineâ terminal;⢠as you rotate toward higher settings you shouldâ see continuity and decreasing resistanceâ (or varying continuity steps) between âthe line (L) andâ the load (element) terminal. Also⢠test âŁfor no continuity between any terminal âand âŁthe âmetal frame (no âshort to ground).⤠Exactâ ohm values vary by manufacturer, so look for⤠continuity changes ârather than specific numbers. If the â¤switch does not open/close or does ânot change continuity as âyou âŁrotate the knob, it is indeed faulty.
How do I âreplace the WB24T10027 safelyâ and âwhat â¤should⣠I âwatch for?
Turn off power at the breaker and verify⢠the cooktop is de-energized. Remove the knobs, âŁtrimand access âŁpanel to â˘reach the switch. Label or photograph⤠wiring before disconnecting â¤so you can⤠reconnect correctly. Replaceâ withâ an identical part (same âterminal layout, âvoltage andâ wattage rating). âReconnect wires â˘securely to⣠the same terminals, reassemble, restore âŁpowerand⢠test all settings.â If you areâ not comfortableâ working on⤠household mains âwiring, hire â˘a qualified âŁappliance technician.
Is WB24T10027⣠compatible with â˘my GE range model?
compatibility depends on⢠the ârange model and the⣠element size/type.WB24T10027 is âused âŁon many⤠GE/Hotpoint/other ranges,⣠but you âmust confirm compatibility by âŁchecking your âappliance’s model number, â˘the part number in the service manual⣠or parts diagramor âcross-referencing with an official⢠GEâ parts â˘list. Do not⤠rely on physical appearance⢠alone-verify the electrical rating â˘and terminal layout match your original⣠switch.
Can I âsubstitute a different wattage infinite switch if I can’t find WB24T10027?
No-do not substitute a lower-ratedâ switch because âit may overheat âŁor fail; doâ not substitute a higher-rated switch â¤unless â¤it is electrically identical and the terminal functions are â˘the same. The replacement must match the element⢠wattage âand voltage rating and have âthe same terminal configuration and control steps. if â˘unsure,get⣠the⢠exact OEM part number or â¤an approvedâ cross-reference.
How much does âreplacing this switch typically cost and where⣠can I⢠buy it?
Prices vary⣠but expect âŁthe part cost to range from â˘a⣠modest amount (typically under $100) plus âŁany⣠labor if â¤you âhire a technician.⤠Purchase from authorized GE parts âdistributors, applianceâ parts retailersor reputable online â¤parts stores-verify the âŁseller lists âWB24T10027 explicitly and â˘confirm⣠return policies in case â¤ofâ fitment issues.
