WB24T10153 GE oven Infinite Switch controlâ is a rotary powerâ control switch used on GE electric cooking appliances to regulate the amount of electrical power delivered to a heating element. As an “infinite” â˘or variable switch, it provides⤠a continuous range of settings ârather than fixedâ steps, allowing the user to select intermediate heat levels by changing the duty cycle or contact engagement rather than by simple âon/off switching.
Inside an â˘appliance, the infinite switch is mounted behind âŁthe control panel and interfaces directly with the user knob, theâ heating element, the⢠appliance wiring harness,â and⢠the line power feed.It operates by opening and closingâ internal contacts or varying conduction time toâ modulate current to the element, âŁand it must coordinate with other systems such as the main control board, temperature sensors or thermostatsand safety interlocks. Proper electrical connections, secure mountingand intact internal contacts are essential for consistent heating performance and safe operation.
this article explains the WB24T10153’s function and typical applications,outlines how to determine âcompatibility with âspecific GE models,and describes common failure symptoms such as no âheat,intermittent âheating,a knob that âdoes not change power,or a burner that stays on. It covers practical troubleshooting steps a technician can perform (visual inspection,continuity and voltage checks,and swapping with⤠a known-good unit),and it discusses replacement considerations including matching terminal layout,mounting style,electrical ratings,and basic safetyâ precautions during replacement.

Function and⢠Role of âthe âŁInfinite switch Assembly in Electric Oven⣠Surface Element Control
The WB24T10153 GE Oven Infinite Switch Control is⢠a rotary power-regulating switch used on electric range surface elements to provide⢠variable heat settings by modulating the element duty cycle. Internally theâ switch combines a âdetented rotary cam⢠with contact assemblies (often âworking with a bimetal or timing mechanism) so that intermediate knob positionsâ produce a controlled âon/off cycle rather than a continuous, intermediate-voltage output. In service âthe control switches line voltage to the element through spade terminals sizedâ for household range wiring; proper replacement requiresâ matching the terminal â˘configuration, mounting footprintand knob indexing to ensure electrical and mechanical compatibility.
Technicians diagnose switch behavior⤠by observing symptoms such âas loss of âintermediate settings, continuous on or off states, intermittent heatingor visible arcing at the terminals; these indicate contact wear or internal failure rather than an element fault. Practical replacement steps include confirming the part number,verifying terminal labeling against the range wiring schematic,and performing continuity and cycling checks with the power disconnected. For example, a burner⢠that heats only on the highest setting but not lower ones often reflects a failed infinite switch contact path rather than âŁthe element itself, â¤so confirming correct terminal connections and knob position alignment is essential before and afterâ replacement.
- Function: modulates element powerâ via timed contact cycling to provide variable heat output.
- Common symptoms of failure: loss âŁof âintermediate heat, stuck on/off, intermittent operation, visible arcing.
- Compatibility:⢠match WB24T10153 mounting, terminal layoutand knob indexing to the appliance âŁharness.
- Diagnostic â˘checks: visual terminal inspection, continuity testingand knob operationâ verification (power off).

How the âWB24T10153â GE Oven Infinite Switch Control Operates Within the Cooktop Power and control Circuit
Theâ WB24T10153 GE Oven Infinite Switch Control is a rotary, variable-position switch that regulates the amount of mainsâ power delivered to a cooktop surface element by changing the on/off duty cycle of the hot feed. Installedâ in series â¤with the element, the switch alternates its internal contacts according to the knob setting to provide âa range of heat⢠output rather than a single fixed voltage; at higher settings the contacts remain closed longer per cycleand at lower settings they open âmore frequently. In a typical 240 VAC cooktop â¤circuit the switch â¤interrupts one hot leg (or â¤both in some designs) and also provides a source for the surface indicator lamp, so correct terminal identification and âmatch to theâ appliance wiring is⣠required for safe operation and accurateâ control behavior.
- Controls element power by cycling mains feed to adjust effective duty⣠cycle across knob positions.
- Contains multiple terminals: incoming line, load to the element, â˘circuitâ for âindicator/pilotand chassis âŁground/neutral reference depending on model.
- Common⤠failure modes: intermittent contact (arcing), stuck closed or open positionsand degraded contact resistance⣠causing uneven heating.
- Compatibility depends â¤on matching electrical rating, terminal layoutand⤠shaft/knob fit to the GE cooktop model.
| Item | Description |
|---|---|
| Function | Variable control of cooktop element power via stepped or timed contact⢠switching. |
| Electrical rating | Nominal 240 VAC operation; confirm current rating on the part label or service manual before replacement. |
| terminals | Line (incoming hot), Load (to element), Indicator/Pilot circuitand â¤chassis ground/neutral as applicable. |
For troubleshooting and installation, â˘verify that the⢠WB24T10153 wiring matches the â¤cooktop â¤harness and that the part’s voltage/current specification equals or exceeds the original.Techniciansâ commonly bench-test âthe switch by measuring continuity âbetween the line and load terminals while rotating the shaft to observe the expected change in contact closure; under-power checks involve measuringâ voltage at the element âterminalâ across different knob settings to confirm proportional duty-cycle behavior. If a cooktop exhibits no heat, uneven element temperatureor an indicator lamp that stays lit or never illuminates, inspect the infinite switch for⤠high-resistance contacts, mechanical wearor incorrect wiring before replacingâ the elementand always â˘disconnect mains power before performing live tests.
Common Failure Symptoms and Operational Indicators of a Defective Infinite Switch
The WB24T10153 GE Oven Infinite Switch Control is the rotary selector â¤that regulates power to a bake orâ surface heating element by switching between discrete contact taps rather than⣠providing a continuous variable output. In normal operation the âswitch routes line voltage âthrough a series of stepped contacts to âthe element, â˘producing predictable heat levels as the knob is advanced. Compatibility is model-specific: the WB24T10153 uses a particular terminal layout and mounting flange, so confirm theâ part number and terminal âlabeling against the appliance wiring diagram before replacing âtheâ control â¤to ensure correct electrical and mechanical fit.
- Burnerâ or element does not heat at any setting
- Element heatsâ only on the highest setting or⢠skips low/mediumâ steps
- Intermittent operation or⤠cycling that does not match knob position
- Visibleâ arcing, charring,⣠or a persistent burning â˘odor⤠at the switch
- Breaker trips or fuses blow when âŁselecting certain settings
Technically, most failure modes stemâ from worn or pitted âcontact surfaces, broken internal cams or detentsor shorted âinternal â˘wiring. A technician can âverify failures with a⣠multimeter by measuringâ continuity and resistance across the switch terminals in each knob position and by checking for proper line voltage at the incoming terminal⢠when â¤the switch is operated.Practical examples:â an open circuit on all positions indicates an internally open switch; continuity only on⣠the highest tap typically indicates worn lower-contact taps; visible carbon tracking or sparking at the terminal block indicates contact degradation and a safety risk. When replacing the component, transfer the harness and note terminal labels so that the new WB24T10153 is wired identically to maintain correctâ controlâ behavior and element protection.
| Item | Description |
|---|---|
| No heat | Open⢠internal contact or broken cam; continuity absent across output terminal in every position. |
| Only âhighest settingâ works | Lower-tap âcontacts worn or burned; selector only connects the final high-power tap reliably. |
| Arcing or burning smell | Contact pitting or loose⣠terminal; visible carbon deposits or melted insulation require replacement. |
Compatibility and applicable GE Oven/Cooktop Models for â˘WB24T10153 Replacement Parts
theâ WB24T10153 GE Oven Infinite Switchâ Control is⤠a rotaryâ power control âused on electric ranges and cooktops to vary the heat to surface⣠elements by cycling the element on⣠and off across a range of knob positions. Technically, it functions as a variable duty-cycle switch (often called an âinfiniteâ or continuous control) and must match the appliance’s electrical characteristics-voltage rating, âterminal configurationand element type-to operate correctly. Physically â¤compatible replacements share the same shaft diameter and length, mounting-hole patternand terminal layout so the control mounts flush in the console and wires connect without modification.
To determine applicability for a given GE or compatible-range model,compare the service-part number⢠and the physical/electrical âattributes⤠rather than relying solely on model-year or family names. Technicians commonly verify fit by checking the control’s terminal count and labeling,â confirming the shaft and knob interface dimensionsand measuring electrical continuity/resistance values across switch positions to ensure the replacement will reproduce the original power stepping and load handling characteristics. Below are practical checks to confirm compatibility before installation:
- Terminal layout: Match the number âand arrangement of spade terminals and any labeling (L1, L2, P, etc.).
- Shaft and mounting: Confirm shaft diameter, length, spline/knob fitand mounting-hole spacing.
- electrical⢠rating: Ensureâ voltage and current â¤ratings match the range element ârequirements (typically line voltage surface â˘elements).
- Part-number cross-reference: Verify the⢠WB24T10153 marking or cross-reference in the appliance service sheet or parts catalogue.
| Item | Description |
|---|---|
| Typical voltage | Line voltage for surface elementsâ (verify appliance nameplate) |
| Terminal count | Usually 3 or 4 spade terminals depending on single/double element control |
| Mounting | Panel-mounted with specific shaft length and mounting-hole pattern-must match cabinet cutout |
Replacement Considerations, Safety Precautions, â¤and StepâbyâStep Installation for the Infinite Switch
The WB24T10153 GE âOven Infinite âŁSwitch Control isâ a rotary power controller âthat regulates the average power delivered to anâ oven or cooktop heating element by switching âthe element on and off in a controlled duty cycle. It is not a temperature sensor; instead it provides stepped â¤variable heat settings via an internal⣠contact assembly and â˘timing mechanism. When selecting a replacement,match the shaft diameter,mounting flange,terminal layout,and operating voltage to the original part number to avoid misalignment of⤠the knob index or incorrect wiring. Technicians should verify that the replacement’s terminal labeling corresponds to the bake/broil and common terminals on the appliance wiring harness to ensureâ correct circuit routing and avoid backfeeding other elements or control circuits.
- Disconnect main power and verify zero⤠voltage with a multimeter before accessing the switch.
- Document and/or tag each wire to preserve terminal mapping; remove spade âconnectors with a pull andâ not â¤by twisting⢠the wire.
- Remove â¤the control panel screws andâ extract the old switch, noting mounting orientation and any insulating â˘washers or shims.
- Install the new âswitch ensuring the shaftâ and⢠index tab align; reinstall mounting fasteners to specified torqueâ to prevent housing distortion.
- Reconnect wires toâ the matching âterminals, reassemble panels, restore powerand perform heat-rise and continuity checks at each control setting while observing for arcing or overheating.
Before full use, confirm functional behavior by checking thatâ each setting produces aâ corresponding change in element duty cycle and that the âŁswitch does not exhibit excessive mechanical play or intermittent contact.â If the⢠switchâ shows intermittent continuity on resistance testing or produces visible arcing underâ load, âthe component should be replaced ratherâ than repaired. Use insulated tools and appropriate PPE whenâ working⣠near live circuits during verification; such as, measure voltage at the rear of the control only after reassembly and with caution to avoid accidental âshortingâ of adjacent spade terminals. Retain the âŁoriginal part number and any model-specific notes to ensure future compatibility when servicing similar GE ranges.

Troubleshooting Procedures and Diagnostic tests (Continuity, Resistanceand Live Circuit Checks) for Infinite Switch Failures
The WB24T10153 GE Oven Infinite Switch Control is a multi-position rotary control that modulates the cooktop element âby switching between internal taps and a resistive coil to vary heat output. When diagnosing failures, understand that the â˘component functions as a selectorâ that either routes mains voltage to the element or inserts resistance/cycling to reduce power; mechanical wear, âcontactâ pittingor internalâ short/open conditions will produce symptoms such as no⣠heat on any setting, full power only, intermittent âheatingor arcing at the âknob. Compatibility checks should confirm the replacement has the same terminal layout and voltage/current â˘ratings as the original, since wrong terminal assignments or a lower-rated part can cause improper operation or rapid failure in a GE range application.
Troubleshooting combines visual inspection, continuity andâ resistance measurements with the power⤠offand controlled live circuit verification when necessary. Disconnect power and remove the switch to perform continuity and resistance checks across the common and each tap; a functioning infinite switch will show continuity paths that âchange as the shaft is rotated and should â¤not present a high-impedance open except in the designated âOFF position. For live circuit checks verify with the stove powered (use insulated tools⣠and appropriate PPE) that the switch makes and breaks line voltage to the âelement terminals in expected âŁpositions using an AC voltage meter-if the switch does not switch voltage as the knob moves, the internal contacts are failing. Compare readings⣠to⢠the oven wiring diagram or a known-good switch and, when in doubt, replace the WB24T10153 GE Oven âInfinite Switch control rather⤠than attempting unreliableâ repairs on âpitted contacts.
- Inspect for burned contacts, loose âterminals, âand mechanical play in the shaft.
- Continuity/resistance: power off,measure between⣠common and each âŁtapâ while rotating the knob.
- Live check: with safety gear, confirm line voltage is delivered/removed at element terminals across knob positions.
- Reference terminal âŁmapping and ratings to ensure correct replacement and âwiring.

Q&A
What is the WB24T10153 infinite switch and what âdoes it do?
The WB24T10153 is an OEMâ infinite⢠(or â¤surface burner) control switch used on many GE electric ranges and cooktops. It⣠regulates the power delivered to a surface heating element by switching the element on and â¤off in varying duty cycles, which provides variable heat â˘settings from low to high.
What areâ common symptoms that the WB24T10153 has failed?
Common signs include a burner that will not heat at all, a burner that is stuck on one setting (such as only works on high), erratic cycling or clicking, the stove element staying hot even whenâ the knob isâ turned offor inability to control heatâ levels smoothly.
How can I safely check whether the infinite switch is bad?
Always disconnect power at the circuit breaker before accessing the switch. Visually inspect wiring and terminals forâ burns or loose âconnections. A basic electrical test with a multimeter (ohms/continuity) can be done: with the switchâ removed and power off, check that the common terminal continuity changes as you rotate the control (OFF should show open circuit to the âload terminal; HIGH should show⤠continuity). Because lower settings use cycling,⤠continuity can be intermittent at those positions. ifâ you⤠are unsure or need to perform live-voltage tests, hire a qualified âtechnician.
Do I need any special tools to replace the WB24T10153and how difficult is replacement?
Typical tools are a screwdriver set and possibly needle-nose pliers. Replacement difficulty is moderate: turn off power, pull off âthe control knob, remove the control panel or trim to access the switch, label and disconnect theâ wires, remove and replace the âswitch, reconnect wires in original positions âand reassemble. If you are not âcomfortable working on household wiring or the controls areâ integrated into the console, âŁget a technician âŁto do the replacement.
How do I make sure I buy theâ correct replacement part?
Confirm the exact part â¤number (WB24T10153) and match it to your appliance model â¤number. âŁUse â¤the range/rangeâ top’s model number (from⤠the appliance tag) when â¤searching. Buying an OEM part from GE or an authorized parts supplier is recommended to ensure fit andâ electrical compatibility. Do not assume visual similarity alone-terminal layout and shaft size must match.
Can a bad element or loose wiring mimic a failed infinite switch?
Yes. A defectiveâ surface element,a bad element terminal block,or loose/corrodedâ wiring can â˘produce identical symptoms (no heat,intermittent heat,or stuck-on behavior). Before replacing the switch, inspect the element and its connections and âŁtest âcontinuity of the element and wiring. Troubleshoot systematically: element â terminal block â switch.
Is it safe to test the switch with live âvoltageâ to diagnose it?
Live-voltage testing should only be done⤠by someone experienced with mains electricity. It involves applying power and measuring voltage at the switch output while operatingâ the control. Incorrect live testing risks shock, shortingor damage. If you are not trained and comfortable working live on household circuits, hire a qualified applianceâ technician.
How much does the WB24T10153 cost and are there â˘any tips to save money?
Typical parts prices (at the time of purchase) are modest-frequently enough in â˘the range of about $20-$60 for the switchâ itself. Labor to replace it will increase the total if âyou âŁuse a technician. To save money, verify the fault carefully (element vs. switch), confirm the correct part number before orderingandâ install it yourself only if you are comfortable with basic appliance electrical work and follow safety precautions.
To Conclude
The WB24T10153 GE Oven Infinite⢠Switchâ Control serves as a central control component for surface elements, regulating the power delivered to burners across a continuous range of â¤heat settings. By converting knob position into the appropriate electrical âoutput,â the infinite switch enables consistent temperature adjustment, reliable cooking performanceand contributes to safe operation of the cooktop. Its proper function is therefore integral to both everyday use and overall appliance⢠longevity.
When symptoms such as erratic heating, loss of specific heatâ settingsor unresponsive burners arise, accurate diagnosis is essential to determine whether the infinite switch⢠is the root cause. Objective âŁtesting⤠and inspection âŁreduce the risk of unnecessary part replacement and help identify other potential faults in the control circuit or wiring. Conversely, when testing indicates switch failure, timely replacement restores âperformance and reduces safety risks associatedâ with electrical faults or⤠uncontrolled heating.
Selecting the correct replacement part and following appropriate⤠service practices helps ensure compatibility and long-termâ reliability. For users without diagnostic experience, engaging a qualified technician provides a measured approach that balances cost, safetyand effectiveness. thoughtful diagnosis and, when warranted, proper replacement of the WB24T10153 contribute directly to appliance⣠performance and user confidence.
