WB24T10153⣠GE Oven Infinite âSwitch Control is an electro-mechanical power controlâ device used to vary the delivery of mains power to an oven or range heating element.As an⤠“infinite” switch it provides a range of heat settings ratherâ than discrete on/off states by modulating the average current supplied to the element; the component consists of a rotary actuator, contact assembly and internal resistive or timing elements enclosed in aâ serviceable housing. Theâ part is a field-replaceable control frequentlyâ found on GE ranges and ovens where a⣠user-selectable⤠continuous⤠adjustment of heat is required.
Inside the appliance the WB24T10153 interfaces between the âuser control (knob or front panel control) and the high-current heating circuit. It receives input from the user selector and â¤closes or opens internal contacts to regulate current to bake, broil or surface elements; inâ some models it also âworks in conjunction âwith thermostats or the electronic controlâ board to âmaintain set temperatures. Functionally it interactsâ with line-voltage wiring, terminal â¤harnesses, heating elements and any temperature-sensing or safetyâ interlocksand it is indeed designed to handle the high⢠voltages andâ currents typicalâ of âdomestic cooking appliances while isolating the control mechanism from the heating load.
In this article you will learn the WB24T10153’s intended function, typical âinstallation⣠locations⤠and model compatibility,â common failure symptoms (for example⤠loss of heat, intermittent operation, â˘stuck-on elements, arcing or physical damage)and practical troubleshooting steps âŁsuch as visual inspection, continuity⢠and voltage âchecksandâ isolating the switch from other components.â Replacement considerations covered include verifying part numbers and ratings, correct wiring and mounting orientation, safe de-energized procedures for removal and installation,â and testing after replacement. The guidance is⣠intended to support safe, âinformed diagnosis and repair rather than to replace specific service manuals or manufacturer instructions.

Function and Role of the Infinite âSwitch in Oven⢠Surface-Element Power Regulation
WB24T10153 GE Oven Infinite Switch Control isâ a rotaryâ electromechanical device that regulates a surface element’s output by varying the proportion of time the âline voltage is applied to the element. Rather âthan modulating voltage continuously, the âswitch uses stepped contacts and a timing âcam⢠or resistive network to produce a dutyâ cycle that corresponds to the knob position, so higher settings⤠increase the on-time and lower settings reduce it. In practical terms, the component must match the element wattage, supply voltage and terminalâ layout on the⢠range; mismatches in â˘amp rating or terminal configuration can cause overheating, poor controlor mechanical fit issues when replacing âthe unit.
- Primary behavior: duty-cycle switching to âapproximate intermediate heat levels.
- Common symptoms of failure: no heat, element stuck powered,â or erratic/intermittent power at certain knob positions.
- Compatibility factors: matching electrical rating (amps/voltage), terminal count/arrangementand mounting orientation.
Technically, âtheâ infinite switch converts⢠a user-selected knob position into a ârepeatable contact sequence that controls average power â¤to the âcoil; this makes temperature control predictable for standard resistive elements but unsuitableâ where â¤true continuous power modulation is required. For field diagnosis, technicians â˘verify that the incoming line voltage is âpresent at the switch and then confirm that the switch changes continuity at diffrent settings; if the switch mechanically appears intact but fails to switchâ under load, the internal contacts or timing mechanism are typically worn. For replacements, choose an exact or manufacturer-specified cross-reference to preserve electrical ratings âand â¤terminal mapping so that the range’s element, indicator lights âŁand safety interlocks continue to â¤function correctly.

How the WB24T10153 GE Oven Infinite Switch Control interfaces with Range Wiring, Thermostatand⢠Element Circuits
The WB24T10153 GE Oven infinite âSwitch Control is a rotary power-control assembly that modulates line voltage to heating circuits by⣠varying the duty cycle of the outputâ contact. Installed in the range wiring harness, it provides the selectable⤠power levels that feed â˘the element circuits and interfaces with⤠the oven’s temperature control and safety âdevices via distinct spade terminals. The switch does not provide a continuous analog voltage output; instead, its internal contact assembly rapidly connects and disconnects the mains to achieve lower average power at reduced settings, so⤠compatibility requires matching the connector layout, voltage rating (typically 120/240 VAC as used on GE ranges)and mounting configuration on replacement parts.
- L1 / L2 – incoming âŁmains line connections.
- LOAD / âŁElement â – output(s) that feed the heating element coil.
- Thermostat / Limit – interface for âŁthe oven âthermostat or âsafety limiter to interrupt or route power.
- indicator / Pilot lamp terminal – powers the cooktop âor selector indicator where present.
In âpractical wiring, the thermostat and safety limiter either sit inâ series with the element feed or in a controlâ loop âŁthat removes the element from the switched line âwhen⣠a temperature limit is reached; â¤the infinite switch supplies the selectable, cycled feed to that loop. For troubleshooting,technicians verify that at a high selector position there is continuity from the appropriate line terminal to the âload⢠terminal and that cycling behavior⢠appears at âlower settings; a⢠failed switch typically shows an open or intermittent contact on those terminals rather than a failed thermostat. when replacing the part, ensure the terminal functions on the new WB24T10153 match the original harness layout and that connector types (spade sizes and positions) âŁpermit a secure, âlow-resistance connection to prevent overheating.

Common Failure Symptoms and Diagnostic Tests⤠for Infinite Switch Malfunction
The WB24T10153 GE Oven Infinite â¤Switch Control⢠commonly âŁfails by losingâ its stepped-resistance behavior orâ by developing intermittent contactsand these âfailures produce characteristic symptoms at the cooktop. Typical observable behaviorsâ include⢠burners that stay at full⣠power regardless of knob⤠position,burners that only heat at certain settings,intermittent cycling on andâ off,orâ complete loss of function atâ specific knob positions. These symptoms âŁindicate internal contact wear,a failed wiper assembly,or a short/open âŁcondition between the common and output terminals rather than a problem with the element or wiring. For example, a burner that⢠is full power on low suggests a shorted pathâ between the commonâ and high terminal; a burner that works intermittently â˘while turning the knob points to mechanical contactâ degradation inside the switch housing.
- No heat on some settings – suggests an open circuit in the switch; verify continuity across the common and corresponding tapâ as the knob is rotated.
- Full powerâ regardless of setting – indicates a short to the high terminal or⢠a stuck wiper; measure resistance from common to high while cycling theâ control.
- Intermittent â¤heating or erratic behavior – frequently enough caused by worn contacts or contamination; perform aâ continuity sweep while movingâ the shaft to reproduce the fault.
- Visible burning or smoke smells – remove power and inspect for heat damage and melted insulation before electrical testing.
Disconnect power before testing. âStart â¤diagnostics with a visual inspection for burnt terminals or loose connections, then use a multimeter to perform continuity and resistance checks across the switch terminals while rotating the shaft; a functioning infinite switch will show changing continuity/resistance as the knob moves between âstops. If safe and necessary, apply a controlled voltage⣠and measure output terminal voltage under load to confirm proper switching behavior – lack of steppedâ changes or persistent full-line âŁvoltage at low âŁsettings confirms the switch as the fault.Confirm compatibility before âreplacing: the replacement WB24T10153 GEâ Oven Infinite Switch Control must match the original terminal layout, mountingandâ the appliance’s rated line voltage and current; if terminal labels or ratings differ, select a part with identical specifications or consult the service manual.
| Item | Description |
|---|---|
| Continuity test | Measure continuity between common â¤and each output terminal while turning⢠the knob; lack of expected changes indicates internal failure. |
| Voltage under load | Measure voltage at the output â¤terminal under element load to confirm stepped control versusâ constant full voltage. |
Compatibility, Replacement Considerationsand â¤Step-by-Step Installation for⢠WB24T10153 in Supported GE Oven Models
The WB24T10153 GE Oven Infinite Switch âControl is an electro-mechanicalâ selector âthat regulates surface-element heat by switching element power through stepped contacts âŁand series resistance rather than providing true infinite continuous control. In supported GE range and cooktop assemblies the switch combines the line,element,and multiple stepped outputs on âa single mounting flange and shaft; compatibility depends on matching the terminal layout,shaft length,knob coupling,and âŁmounting bracket. Technically,you should verify the switch’s terminal function (line,two element terminals,and a common or pilot terminal where used) against the oven modelâ wiring diagram â¤before replacement,as the physical âŁconnector arrangement and contact sequencing determine whether the part will operate â˘an elementâ correctly and safely in that âŁchassis.
Replacement andâ installation require straightforward âmechanical and⢠electrical verification: isolate power,â document âwiring positions (a photo or labeled diagram)and confirmâ the failed switch with an ohmmeter by checking continuity through selector positions (open at OFF, stepped â˘continuity on heat settings). Typical installation steps include removing the control knob and bezel, releasing the mounting fasteners, transferring or â¤replacing the switch âassembly, restoring wires to the exact terminalsand testing cycling at âlow-to-high settings while monitoring for correct element switching and absence of arcing. The following swiftâ checklist and âŁreference table summarize practical checks and common parameters to confirm compatibility before and after installing the switch.
- Power off at breaker and verify with a meter.
- Remove knob and control panel to access the switch.
- Record or photo each wire location; test switch with a multimeter across positions.
- Install new switch, âsecure mounting, reconnect â¤wires exactly, restore⣠power and verify âelement response across settings.

Q&A
What is the WB24T10153 infinite switch and what⣠does⣠it do?
The âWB24T10153 is an infinite (stepped) surface burner control switch used on many GE ranges. It varies the amount of power supplied to a cooktop burner âŁby switching between different internal contacts/resistors as you turn the knob,â allowing incremental heat settings from low to high. It is a mechanical control, not an electronic control board.
What are common symptoms of a failing⣠WB24T10153?
Common symptoms include a burner that won’t heat at all, a burner that stays on at âone âsetting (usually low or full), intermittent or erratic heat changes as you move the knob, visible â˘burning or melting around the switchor the⣠knob slipping on the shaft. These indicate internal contact wear or failure of the switch.
How â˘can I test the infinite switch with a multimeter?
First, disconnect power to the range. Remove the control knob and control panel to âaccess the switch and â¤its terminals. With the switch âremoved,⢠use an ohmmeter to âcheck⢠continuity between the âcommon â˘(input) terminalâ and the various position terminals while rotating the shaft through settings-the reading should change and show continuity at⣠positions that correspond to the chosen setting. Also check for an open circuit in all positions (bad) or a â˘permanent short/continuity to ground (bad). Consult âyour specific model’s wiring diagram to⤠identifyâ terminals and â¤expected continuity pattern before testing.
Can I replace the WB24T10153 myselfand what âare the basic steps?
Yes, a competent âDIYer âcan replace it, but always cut⢠power at the breaker first. Basic steps: turn off power and confirm with a voltage tester; remove the control knob(s); unscrew/remove the controlâ panel to access the switch;â label or⤠photograph wires âŁand their terminal positions; pull off spade connectors and remove mounting âscrews; install the new â˘switch, âreattach wires to the correct terminals, reassemble the paneland restore power. If you are unsure âabout wiring or working around live circuits, hire a qualified technician.
How do I confirmâ the replacement part is compatible with my GE range?
Confirm compatibility⤠by matching the WB24T10153 part number to the⢠model number of your range using the owner’s manual, GE parts âdiagramsor the parts lookup on the GE Appliances website. Don’t rely only on visual similarity-verify the part number and model compatibility becauseâ terminal layouts and shaft lengths can vary between models.
Could a bad infinite switch be mistaken⣠for other problems? What elseâ should I check?
Yes. Symptoms like noâ heat or erratic heat can also be caused by a failed burner element, broken wiring/harness, loose spade connectors, a⣠faulty control âŁboard or clock/timeror a bad thermostat/oven sensorâ (for oven functions). Before replacing theâ switch,⣠inspect the â¤element and wiring, test the element for continuity,⣠check connector tightnessand rule out control board issues with visible damageâ or error codes.
Is⣠there âany calibration, adjustmentor⤠maintenanceâ needed after installing a new infinite switch?
No electronic calibration is required-the â˘infinite switch is a mechanical stepped control. After installation, make sure the shaft and âŁknob align correctly and that the knob index marks line up with the switch â¤positions. Periodic maintenance is mainlyâ visual-keep the area free of spilled âfood and check for loose connectors. âŁIf the knob âdoes not⢠engage the shaft properly, check for correct shaft type and knob âcompatibility.
