WB24T10119 GE âŁOven Infinite switch control⤠is a rotary,variable-power switching device used in electric cooking appliances to regulate the heat output of heating elements. As an infinite (or âstepping) switch, it provides a range of⣠user-selectable power settings rather than a single on/off stateand is packaged as a⢠replaceable control assembly that mounts behind âtheâ control knob on many GE ranges and ovens.
Inside the appliance, the infinite switch modulates the âamount of line⢠voltage deliveredâ to a designated heating element by selecting differentâ resistive or tap positions and byâ cycling power on and off âŁat varying duty cycles. It interfaces⢠directly â¤with the heating element terminals, the user â˘knob,â theâ appliance⢠wiring harness and, in some designs, with indicator lights â˘or interlock circuits. Because it controls current flow to âthe element, it âmust be âcompatible with the element’s⢠wattage and the appliance’s â¤supply voltage and âis a key component in achieving predictable temperature response âand safe operation.
In⣠this âarticle readersâ will find a technical overview of the WB24T10119-how âit functions electrically and mechanically, where it is â¤typically usedand how to verify compatibility when sourcing aâ replacement.

Function and âRoleâ of the Infinite⤠Switch Assembly in GE Electric Oven Heating âControl
The WB24T10119 GE â˘Oven Infinite âSwitch âControl is a mechanical power regulator used in many GE electric âranges to vary heat⤠delivered to a heating elementâ by changing âthe contact timing and internal resistance⣠path as the userâ adjusts the control⤠knob.⣠Functionally it provides a continuous range of heat settings by altering⤠the duty cycle of mains power to the element: at lower settings the contacts âclose for short pulses, at higher settings⢠they remain⢠closed longer.The assembly⣠is a contact-based device (not solid-state) that interfaces with the⣠oven âŁthermostat or control cycling; its behaviour is determined â˘by the cam/slider geometry,â resistive tap arrangement, â˘and âthe internal switching contacts, so wearâ of those â˘contacts will change heating characteristics over time.
- Symptoms of wear or failure: âburner stuck on one âsetting, âŁinsufficient heat, intermittent heating,⣠visible arcing at terminalsor knob positions that do not â¤change output.
- Key functional attributes: âduty-cycle control, mechanical detents for user settings, spade terminal wiring for straightforward replacement.
- Replacement considerations: match⢠electrical ratings and⣠terminal layout to avoid mismatched duty⣠cycles or mechanical fit issues.
For compatibility and practicalâ troubleshooting, verify the switch’s voltage and terminal configuration against the oven wiringâ diagram before replacement; the WB24T10119 shares common mounting and spade-terminal layouts with several GE ârange models but must match the specific harness and panel cutout. In practice, technicians should⢠check for continuityâ at each switch position and inspect for pitting or burned contacts when an oven âexhibits erratic or reduced heating; replacing the switch is â¤typically performed along with cleaning or replacing theâ mating âconnector and confirming that the thermostat and element are within specification to ensure the new switch will provide predictable control. When documenting a repair, record terminal labels and knob âorientation, because incorrect wiring can produce improper âdutyâ cycles â˘or continuous heating.

how the WB24T10119 GE Oven Infinite Switch Control Operates and Interfaces with Heating Elements and control Circuits
The WB24T10119 GE âOven Infinite Switch⤠Control is an electromechanical rotary â˘controlâ that regulates oven heating elementsâ by varying the duty cycle of the incoming mains power.⣠Rather than deliveringâ a â˘reduced voltage,the â˘switch rapidly connects and disconnects the full supply to the bake or broil element so that the element’s⣠average heat âoutput corresponds to the⢠knob position. In âtypical â¤use the infinite switchâ provides a âsequence of timed on/offâ intervals (longer â¤on timeâ for higher settings)andâ it â˘also integrates with the oven’s safety â¤and control circuitsâ so that the âŁoven control board, thermostator selector switch can interrupt power for temperature control or⤠safety shutoff âwithout changing the switch calibration.
- Operates by switching full⤠mains to the âelement âin timed pulses (not by lowering voltage).
- Provides discrete terminals for line, load (bake/broil), â˘common and indicator/light circuits.
- Common failure symptoms: no heating,heating⢠stuck on,or intermittent heating/cycling inconsistent with knob position.
Installation and troubleshooting focus on matching⢠the âswitch’s terminal layout and âŁelectrical ratingsâ to the âoven âharness: confirm the switch is rated for household 240 VAC⣠and the required currentand âverify⣠terminal â˘functions with a wiring diagram or probe before replacement. In practice a technician will âmeasure continuityâ and⤠observe that the appropriate load terminal receives â¤line âwhen⣠the knobâ is rotated; if the switch fails to open or close reliably it will produce the symptoms listed above even if âtheâ control board is functioning. When interfacing with electronic control modules, the infinite switch usually appears as a simple switched mains source (load/no-load),⢠so compatibility requires correct terminal mapping and an understanding that the oven’s closed-loop âtemperature control is achieved by coordinated action between the â¤switch duty cycle and the thermostat or control board commands.

Common Failure Symptoms and Diagnostic Indicators of Infinite âŁSwitch Malfunction
The WB24T10119 GE Oven⢠Infinite Switch Control is a multi-position rotary control used on many⣠GE coil-surface ranges to regulate power to⣠a cooktop⢠element by changing contact engagement and duty cycle.The switch routes incomingâ line voltage to the heating element through a cam-operated contact assembly so each knob position produces a⣠different âon/off cycle or continuous âfeed; compatible replacements must âmatch the mounting flange, terminal patternand cam profile to maintain âproperâ heat curves. In practical terms, aâ correctly functioning WB24T10119 will allow smooth progression from low⣠cycling to⣠full continuous power at the high â¤setting, while mismatched or â˘worn units produce erratic power delivery or poor⤠temperature⤠resolution âevenâ if the element âitself is serviceable.
Common failure⤠indicators are electrical⣠and mechanical: âintermittent or no continuity⤠at â˘multiple knob positions, a â¤burner that only âheats on the highest setting, visible heat damage or melted terminalsand audible or tactile looseness as theâ cam â¤rotates.disconnect power beforeâ testing. Technicians typicallyâ verify faultsâ with a multimeter by checking continuity âŁbetweenâ the line and load terminals as the knobâ is advanced â(expect intermittent⢠continuity at low positions and steady continuity at high positions) âand by measuring voltage at the element terminal under load. Physical signs such as carbon tracking on contacts, excessive play⤠in the shaft, âor burned plastic housings correlate strongly with internal contact⢠failure and warrant replacement rather than cleaning.
- Burner cold at all settings but element intact – open contact⣠or broken terminal.
- Burner only works on high – contact âwear⤠or failed âcycling cam.
- Intermittent operation -â loose shaft, worn detent,â or partial continuity in switch.
- Visible melting or burns âŁat terminals – immediate replacement recommended.

Replacement Considerations and â¤Safe Installation Procedures for the Infiniteâ Switch Assembly
The WB24T10119⤠GE Oven Infinite Switch Control is âŁa rotary, multi-position switching assembly that regulates surface element powerâ by selecting stepped contact positions and modulating duty cycle. The âassembly uses a stack âof mechanical contacts to route mains⢠to the cooktop element; wear, â¤carbon build-upor a⣠broken contact carrier changes contact resistance and alters element behavior (intermittent âheat,â failure to reach low settingsor remaining energized). Confirm compatibility before replacement by matchingâ the switch’s terminal diagram, mounting âŁflangeandâ printed voltage/current⣠ratings to the appliance service⤠documentation so that element phasing and conductor routing remain correct.
Safe installation requires electrical isolation, accurate documentation âŁof existing wiringand functional⣠verification after reassembly. Disconnect power atâ the service breaker, open the appropriate accessâ panels per the service manual, photograph and tag each conductorand use⢠a meter to verify zero voltage at the switch terminals before â˘touching wiring. During â˘installation seat the switch flush to the mounting surface, secure terminal screws âand wire⣠terminations properlyand â˘after restoring power perform stepwise tests (lowâmediumâhigh) while observing for arcing, abnormal heatingor incorrect element â¤response; if any symptom appears, remove power and recheck wiring and âterminal integrity.
- Prepareâ tools and PPE: â˘insulated screwdriver, nut driver,â multimeter, gloves and eyeâ protection.
- Label and photograph wiring before⣠disconnection to⤠ensure correct reconnection.
- Post-install checks: continuity across switch positions, element current⣠draw âagainst service valuesand âvisual inspection for âarcing.

Q&A
What is âa WB24T10119 infiniteâ switch âandâ what does it do on my GEâ range?
The WB24T10119 is an infinite â(or rotary) surface element control switch used on GE ranges to regulate the powerâ output to a cooktop heating element. âŁTurning âthe knob moves the â˘internal contacts through a resistive track and a set of detents so the element can be set anywhere from Off through low, simmer, medium, âŁto High. It⣠is not a âtemperature âsensor or thermostat – it simply varies the amountâ of time the âelement receives⢠supply voltage.
What⣠are â¤common symptoms of a failing WB24T10119?
Typical symptoms include a single burner that won’t heat, a burner that only heats on some knob positions, a knob with no detents or that slips, a burner that cannot be turned off, intermittent heatingor visible burning/charring around the switch. âIf multiple âburners are out, the âproblem is often elsewhereâ (element, wiringor supply), but â˘a âsingle-burner issue frequently points to the switch.
How do I safely check whether the infinite switchâ is bad?
Always disconnect theâ range âfrom power before touching wiring. Visually inspect âŁtheâ switch for burn marks or meltedâ housing. With⤠power off you can remove the switch and use a âŁmultimeter set to continuity/ohms: rotate the shaft⢠through positions and verify the output terminalâ to the hot lineâ shows changing⣠continuity (or resistance) per position and is open at Off. For live âvoltage checks (only âif you are qualified), restore power and measure the supply voltage at the element outputâ terminal while⢠changing the knob – when⣠on high it should present supply voltage to the element. If measurements don’t change as expected, the switch is likely defective.If you’re unsure, call a qualified technician.
Canâ I clean or repair⣠the WB24T10119 contacts,⢠or should I replace the switch?
Infinite switches are sealed and not designed forâ user contact âcleaning or⣠internal repair. If inspection or testing indicatesâ failed contacts, burningor mechanical wear, the correct action is to replace the âŁswitch⢠with an⤠identical part.Attempting toâ disassemble or repair⣠it is indeed unsafe and unreliable.
How do I find a correct replacement âand what âshould I match when ordering?
match the exact part number âŁ(WB24T10119) when possible. If you must substitute, confirm the âreplacement⣠matches the original’s terminal layout and labeling, shaftâ length and diameter, mounting âhole spacing, electrical ârating (voltage and amp rating),⢠and connector type. Physical fit and terminal wiring order âare critical-use manufacturer cross-reference charts âor parts suppliers that list compatibility for your oven model.
What âis the correct procedure to replaceâ the WB24T10119?
Turn power to the⢠range off at the breaker and verify it is de-energized.Remove the knob⤠and any cooktop or backguard⣠panels necessary to access theâ switch.⤠Note âŁor photograph the wire connections, â˘then âdisconnect the wires. Unscrew and remove the old switchâ and install the new one,⤠securing it and reconnecting wires to the same terminals. Reassemble panels, ârestore powerand test the burner through all⢠settings. If you don’t have electrical âexperience, have âa âqualified technician perform the replacement.
How can I distinguish a bad element from a â¤bad infinite switch?
Test the element’s resistance with the power off – a good surface element will have aâ measurable low resistance⣠(not open/infinite). If the element measures open, theâ element is bad. If the element checks good, but you get no âŁpower to the element when the knob is turned to high, the switch or its wiring⢠is suspect. Alsoâ check âfor proper â˘supply voltage at the cooktop harness. Diagnosing requires confirming both element continuity and that⤠the switch supplies voltage to the element.
Are⣠there any safety precautions âor common mistakes to avoid whenâ diagnosing or replacing this switch?
Yes. always âdisconnect â¤power at the breaker and verify âabsence of voltage before touching terminals. Do not test internal switch contacts⣠with power applied unlessâ you are trained and⢠use proper insulated test tools. Do not swap wires⤠without documenting original connections.â Avoid using âan âincorrect replacement (different amp/voltage rating or wrong terminal layout). Ifâ you see extensive burnâ damage to surrounding wiring or âharnesses, replace those parts as well and consider professional service.
