Function and Role of theâ Oven âSurface Element Switch in heating Circuit Control
The WB24T10058 GE Oven â˘Surfaceâ Element Switch serves as theâ user-facing selector and electrical control point that âmeters mains voltage to an âindividual surface heating element. Internally it provides a setâ of selectable contact âpositions (or an infinite-tap arrangement onâ some designs) that route line power â˘through the element at⤠varying duty cycles or resistance⣠paths⣠so the⢠element attains different temperature⢠levels.The switch is mechanically designedâ to fit the cooktop’s knob interface and to match the appliance’s âterminal layout so that replacement requires âthe â˘same terminal count,mounting flange,and electrical⣠rating as the original âpart.
In service,the switch behaves as the primary cause forâ symptoms such as âŁno âŁheat,only⢠high-heat operation,intermittent heating,or â¤sparking⤠atâ the â˘knob⢠when âŁrotated. Typical diagnostics include visual inspection for burned⤠or pittedâ contacts, continuity checks⤠acrossâ terminalsâ while rotating the shaftand â¤verifying correct wiring continuity to the element; always disconnect mains power before â˘testing.⤠For âcompatibility and practical âŁreplacement,â compare terminal labels and â¤mounting orientation rather than ârelying solely on part number – a correctâ physical â¤and electrical â¤match ensures reliable operation and safe current handling for the element circuit.
- Function:⤠selects and meters mains power to a â¤surfaceâ element for stepped or⢠variable âŁheat control.
- Common failure modes: worn contacts, mechanical wear ofâ shaft, intermittent⣠continuity,⢠or âthermal damage from overload.
- Troubleshooting: âŁdisconnect power, test continuity through positions,â inspect terminals for heat damage.

how the WB24T10058 GE Oven Surface Element Switch Operates⣠Within the Oven’s⣠Control and Power Circuits
The WB24T10058 GE Oven Surface Element Switch is a multi-position âŁselectorâ that routes the oven’s mains supply to a surface heating âŁelement âthrough discrete contact taps. In the control and power circuits the switch â¤functions as a user-settable powerâ selector: its âŁcommon terminal connects to the âcooktop elementâ and its âposition-selected⤠terminals provide varying resistive âpaths âor â˘direct mainsâ depending on⢠the heat âsetting.Electrically it sits between the supply legs and the element, so correct voltage rating and terminal layout are required for compatibility; incorrect substitutions⤠can result in â¤no heat, continuous heator unsafe âoperation. The switch⣠does not regulate⤠temperature by sensing heat âŁ- it simply selects the amount ofâ power delivered to the element and ârelies on the⢠oven’s control system or user to change settings.
- Common symptoms â˘of⤠aâ faulty switch: element stays on irrespective of âsetting, no âcontinuity inâ any positionor intermittent heating at certain settings.
- Compatibility âchecks: confirm terminal labeling, mounting footprintand rated voltage/current before replacing the part.
- Typical bench test: measure continuity⣠between the common and each output terminal across switch⢠positions to verify expected contactâ closure.
- Safety step: â disconnect power and label wires prior to removal â¤to âpreserve correct âreconnection.
| Item | Description |
|---|---|
| Function | Multi-position power selector for surfaceâ element |
| Key verification | Terminal âmap, voltage/current â¤ratingand contact continuity per position |
For âa â¤practical example, if an⢠oven element does âŁnot âheat on any setting, a technician can remove the⤠switch and⣠use a multimeter to confirm that the common terminal shows continuity to the appropriate output terminals only when the switch is in the corresponding positions; absence âof that behavior indicates⣠worn âcontactsâ orâ internal failure. When replacing â˘the part, match theâ WB24T10058 GE Oven Surface Element Switch âby â¤terminal configuration and⢠electrical ratings, then restore âwiring as labeled and test the elementâ under a controlledâ load âto confirm correct operation in⢠each setting.
Common Failure Modes andâ Observable Symptoms of a Faulty Surface Element âswitch
The WB24T10058 GE Oven âSurface⤠Element Switch is⣠the âelectromechanical â˘control â¤that⤠selects and routes mains power to a surface heating element through discrete contact positions and detents. In âŁproper operation the switch provides⣠a low-resistance path to the â˘appropriateâ element terminal(s)⤠andâ either applies âor interrupts full â¤line voltage (or portions of it via multi-position contacts) to achieve the⢠selected heat level. Failures commonly âŁarise from contact âŁerosion,carbon tracking,or deformation â¤of âthe plastic actuator and mounting features; thes faults change contact resistance,create intermittentâ connectivity,or produce unintended shorts between terminals. For safe inspection⣠and measurement, â disconnectâ power to the appliance before performing continuity or voltage checksand verify any replacement matches â¤the original terminal layout and âelectrical ratings â˘toâ avoid miswiring or overstressing the contacts.
- element âdoes not heat at any setting (open circuit through switch).
- Only certain burners or â¤power levels work (partial contact⢠failure or worn multi-position contacts).
- Element remains energized after the â˘knob is returned to off â˘(shorted or⢠weldedâ contacts).
- Intermittent heating or cycling inconsistent with selector position âŁ(poor contact or broken actuator⢠detent).
- Audible arcing,burning odor,or visible scorch⤠marks at the âŁswitch âŁor harness (contact tracking or âinsulation breakdown).
Electrically, a âŁfaulty switch⢠will present either anâ open circuit⤠when it should be âŁclosed, âan⢠abnormally high resistance that reduces current⤠and element temperatureor a low-impedance shortâ between terminals that should be isolated. Technicians can distinguish theseâ modes by measuring⢠continuity across⢠the switch contacts in âeach knob position and by verifying âline voltage⣠at the switch output with the⤠element connected/disconnected; a closed⢠contact should read⤠near-zero ohms on a functioning switch â¤while an open position should⤠read very high or infinite resistance. Mechanical defects such asâ a cracked âŁactuator⣠or⢠missing detent frequently produce symptoms⢠that only appear under⢠load or with the control exercised; trapâ those⤠failures by âmonitoring continuity while⤠rotating the shaft â¤and observing terminal voltages. Replace the switchâ when contacts⢠are visibly pitted,plastics are⢠deformed,terminal mapping differs from the original,or continuity/voltage âtests indicate⣠unreliable âŁoperation,and always inspect the element and â˘wiring harness to rule out upstream faults before installingâ a new âŁcontrol.
| Item | Description |
|---|---|
| Open/high-resistance contact | Element weak⤠or no heat;â high â˘ohms measured across a âclosed contact. |
| Shorted terminal | Element stays on⢠or multiple elementsâ powered;â continuity between terminals âthat shouldâ be isolated. |
| Mechanical â˘wear | Intermittent operation, no detent âfeedbackor continuity that⤠changes when the shaft is moved. |
Compatibility, âReplacement⤠Considerations, Installation âProceduresand PostâInstallation Diagnostics
The WB24T10058 GE⢠Oven Surface Element Switch â is an infinite selector switch that routes mains power to a surface âelement through âmultiple tap positions, controllingâ the element’s effective power and temperature at the cooktop.Functionally âit âcontains aâ rotary wiperâ and discrete contact taps; technical⢠compatibility âŁis determined by the number and arrangement of âspade⣠terminals, âthe bushing/knob interface, âand the switch’s voltage/current â¤ratings. Typical âfailure modes⤠areâ worn⢠or pitted contacts causing⤠intermittent or no heating, âa seized bushing that prevents position changeor âinternal shortingâ between âtaps; theseâ failures âproduce symptomsâ such as âno-heat on specific settings, continuous âheating regardless â¤of positionor visible arcing under load.
Replacement requires â˘verifying electrical and âmechanical compatibility before installation, labeling and photographing wire positionsand â¤isolating â¤mains power. After mounting and reconnecting, postâinstallation diagnosticsâ should include â˘continuity âchecks âacross selector positions, voltage measurements to the element while â¤the switch âŁis operatedand a short-loadâ operational test to confirm correctâ step changes without overheating or⤠arcing. Practical examples: replacing with an identical â˘WB24T10058 avoids unexpected terminal rearrangement;⣠substituting a visually â˘similar switchâ withâ different tap counts âcan eliminate low-powerâ settings⢠orâ change element behavior.⣠For field troubleshooting,⣠perform these checks:
- Continuity test â˘across the appropriate terminal pairs âŁat each âknob setting to confirmâ expected open/closed paths.
- Voltage measurement at the switch output and at the element under load to detect wiring⤠or element faults versus switch faults.
- Visual and âthermal inspection during operation âforâ arcing, hot terminalsor loose connectorsâ that indicate contact degradation or improper⣠mounting.

|---|---|
| Terminal count | Confirm spade layoutâ (e.g., 4-6â terminals) matches harness or note â˘required adapter wiring. |
| Rated voltage | Typically 240 VAC for range surface âelements; ensure current rating meets element⢠load. |
| Mounting | Single-bushing rotary mount – verify knob/trim compatibility âand bushing length. |
Q&A
What is⣠the WB24T10058⤠andâ what does it do?
The⣠WB24T10058 is anâ OEM surface â˘element⣠(infinite) switch used onâ GE/hotpoint/Admiral electric ranges.It is a rotary control â¤that âŁvaries the amount of electrical âpowerâ sent to a cooktop surface⤠element,⢠allowing theâ user to set heat levels. It is âindeedâ not a temperature sensor or thermostat-it⣠controls voltage/power to the element through stepped contacts inside the switch.
What are âcommon symptoms of a failing WB24T10058?
Typical symptoms include a surface element that won’t heat at some⣠or any switch âŁsettings,an element that stays on or⤠overheats at âthe lowest âŁsetting,intermittent or erratic â˘heating,visible âarcing or⤠burning at the switch terminals,a loose â˘or slipping control knob,or smoke/odor â˘from the switch area. these all suggest worn⣠contacts or internal damage to the switch.
How do⤠I safely test⣠the WB24T10058 with a multimeter?
Always disconnect⤠power to the range⣠at â¤the breaker beforeâ testing. Removeâ the knob and access the⣠rear of the âŁcontrol panel to expose the switch terminals.â Set âŁyour multimeter to⢠continuity or ohms.With the âswitch âin the OFF âposition⢠you should typically see open/no continuity between common and element âterminal(s). Rotate the knob through âsettings; you should âsee continuity appear between the common and one or more load terminals depending on theâ switch âposition. Also check for unintendedâ continuity to ground (shortâ to chassis). Do not âŁmeasure live â¤voltage on the switch unless you⤠are trained and take appropriate precautions-if youâ do measure âlive, use a properly rated meter⣠and PPE.
Are there âresistance (ohm) specifications âŁI can âŁuse⤠to confirm âŁthe switch is âŁgood?
Because â˘an infinite⢠switch uses stepped contacts, there is not a single fixed resistance value to confirm â˘âgoodâ operation-resistance will change with âŁknob âŁposition⤠and depends on the element. The correct test is continuity behavior and absenceâ ofâ short-to-ground or intermittent contact. âIfâ the switch âis supposed toâ feed the element â¤and shows an open circuit âinâ positions⣠that should supply power, it is indeed faulty.⢠For exact resistance or wiring âŁdetails, consult âthe âappliance’s tech sheet or wiring diagram for model-specific specs.
How do I â˘determine if theâ problem is the switch or the⣠surface element?
After disconnecting power, visually inspect⤠both the âŁelement and switch âfor damage or â˘burn marks. You can test the element separately⢠by measuring its resistance across its two terminals-most â¤elements showâ a low but measurable resistance (usually a few ohms, depending on element wattage). To isolateâ the switch, swap the suspect switch with a â¤known-good switch (if available) â˘or â˘temporarily connect the element to a known working circuit. If the element measures OK and the element works when fed directly,⤠the switch⣠is highly likely faulty. If the element is open⣠or âŁshows extremely high resistance, theâ elementâ is at â¤fault.
Is⣠WB24T10058 compatible with all GE rangesand how âdo â˘I be sure âI’m ordering the â¤right part?
The WB24T10058 fits specificâ GE/Hotpoint/Admiral models but â˘is ânot â˘universal âfor all GE ranges.â Check compatibility by matching the model number of your range and the â¤part⣠number shown on yourâ range’s parts list âŁor tech sheet. Also verify terminal layout, shaft length and spline, mountingâ hole patternand electrical ratings.Many âonline parts retailers let you enterâ the appliance model to⤠confirm compatibility.
What⣠is the⢠correct procedure â˘for âŁreplacing â˘the WB24T10058?
Turn off powerâ at the â¤breaker and âŁconfirm there is⣠no voltage. Remove the controlâ knob(s) and access panel to⤠reach the switch. Note and label each wire or take âa photo to ensure proper reconnection. Disconnect âŁwires andâ remove mounting screw(s) âŁand switch. Install⤠the â˘new switch by⣠aligning the shaft and mounting holes,secure it,reconnect the wires to theâ correct terminals,replace âŁthe â¤panel and knob,and restore âpower. Test all settings to confirm proper function. Use replacement âparts that⤠match the â˘original’s⢠ratings and terminal configuration.
Are âthere any âsafety concerns or precautions when⢠replacing this switch?
Yes.Always disconnect electrical power at âthe âsource before working on the range. Avoid âworking on the appliance with powerâ on⢠unless you are qualified and using proper insulatedâ tools âand PPE.ensure wires are connected to the correct terminals-incorrect wiring canâ cause shorting or fire.⢠Inspect âŁconnectors⤠for heat damage and replaceâ any melted⢠terminals or wiring. If you see signs of arcing or âfire damage to the control harness or console, replace damaged wiring and components ratherâ than â¤just the â˘switch.
