Function âand Role of the âŁOven burner â¤Switch âin GE Range Control Systems
The WB24T10145 GE⣠Oven⢠Burner Switch is a multiâcontact electromechanical switch used in GE range control systems to route mains power to the oven burner âcircuit⣠or⣠to send control signals to the igniter/gas⤠valve assembly. In operation the switch provides discrete âcontact closures that correspond to⢠user selections on the range control (bake, broil, âŁlow/medium/high stages), so⤠the correct heating element or â¤ignition circuit receives power. As the part uses mechanical âcontacts, wear, carbon âbuildupor heatâinduced deformationâ can⢠increase contact resistance or produce intermittent connections and visible arcing; these behaviors⢠directly⤠affect oven temperature stability andâ the ability â¤of the burner or âigniter to operate⢠reliably.
Compatibility is persistent by terminal layout, mounting footprintand the âswitching sequence required by⢠the range’s control harness; replacing a failed⤠switch with âŁthe correct OEM WB24T10145⣠preserves the original terminal wiring and âswitching logic. Technicians typically⤠verify â¤operation with a multimeter by checking continuity between specific terminalsâ as theâ control knob is moved through positionsand byâ inspecting for hot â¤spots or pitted contacts. Practical troubleshooting examples include: the â¤bake element â¤receiving no power while broil still worksâ (indicative of a failedâ bake contact),â or intermittent ignition cycles caused by a switch that makes âand breaks â¤under load. Always deâenergize the appliance before bench⤠testing or replacement to avoid â¤shock and further âdamage.
- Common indicators: âno heat in a selected mode, intermittent heating, visible arcing at switch terminalsor burned/melted connector insulation.

Howâ the âWB24T10145 GE Oven Burner Switch Works Inside the Appliance:â Electrical⢠Operation âand Gas Valve Interface
The WB24T10145 GE oven⢠Burner Switchâ is the electro-mechanical selectorâ assembly that routes mains power from the oven’s incoming line to the â˘bake, broiland igniter/valve control circuits according to the user-selected mode and thermostat demand. Internally it â¤uses multiple contact sets and detented positions so that âselecting a mode or âŁclosing a thermostat âcontact â˘completes theâ intended circuit â˘and supplies full line voltage to the igniter or gas-valve coil; asâ the switch carries load⣠current it must match the appliance’s terminal mapping and current rating to avoid âcontact overheating or miswiring. â¤In practice the switch functions like a manual multi-pole relay: it isolates circuits⤠when open âand supplies direct lineâ power when closed, handing off control toâ the oven’s⤠ignition or gas-valve systems â˘only after â˘the correct contacts are made.
Electrically,⤠the⣠deviceâ changes continuity paths based on selector position – â˘technicians confirm correctâ operation by measuring continuity between the common (line) terminal and the mode-specific terminalsâ while âŁactuating the⢠switch and by checking for excessive voltage drop âŁunder â¤load. common âfailure modes are open or intermittent âŁcontacts, pitting or âcorrosion that raises contact resistanceand â¤lose terminal connections; symptoms include noâ bakeâ or broil function, only one mode operatingor erratic cyclingâ of the⣠burner. For practicalâ troubleshooting, perform⢠continuity checks âwith⣠the selector in each position, âvisually inspect⢠spade terminals andâ harness connectorsand always disconnect power ⢠before probing âŁlive circuits.
- Continuity â˘check: common to mode⣠terminal closes in corresponding selector⣠positions.
- Load check: measure âvoltage drop across closed contacts while igniter or valve is energized.
- visual âinspection: look for bent terminals, burnt contact âŁsurfacesor loose connectors.
- Compatibility: confirm terminal layout andâ ratings against the oven’s wiring diagram before replacement.

Common Failure Symptoms and⤠Diagnostic Indicators of a Faulty Oven Burner Switch
The WB24T10145 GE Oven Burner Switch routes âmains voltageâ from the appliance control harness to the bake or âbroil heating circuit and functions as the user-selected power distribution point for â˘the oven’s heating âelements. As an electromechanical multi-position contact assembly, itsâ normal behavior is to present a low-resistance path to the selected terminal and an open circuit toâ others; wear, contact pittingor internal â¤shorting raises âcontact resistance âor produces intermittent connections that manifest as loss of heat, erratic cyclingor localized overheating. Compatibility depends on â¤terminal layout andâ mounting for specific GE/Hotpoint models, so verify âthe WB24T10145 part number and terminal configuration against the oven model before⤠replacement.
Diagnosing â¤a faulty oven burner switch combinesâ visual inspection, static âresistanceâ checksandâ functional confirmation under controlled conditions.â check for obvious signs of arcing, heat damageor carbon tracking on â˘contact faces and housings; âuse âŁa multimeter to measureâ continuity between the common terminal â˘and âeach position with⣠the selector engaged-closed positions âshould readâ low ohms, âwhile â¤othre positions should be open. If a selected function produces no heat despite a good element or theâ oven â¤overheats/stays on, the switch contacts are âa âlikelyâ suspect. Disconnect power beforeâ removal and prefer bench testingâ the switch when possible; if live âtesting is unavoidable, take appropriate safety precautions and use insulated probes.
- No âheatingâ on a selected mode (bake/broil) while the element tests good
- intermittent or cyclic âheating inconsistent with thermostat settings
- Stuck-on function or⣠failure to switch betweenâ modes
- Arcing,visible burn âmarks,melting,or a burning odor at â˘the switch area
- Elevated⤠resistance readingsâ on âŁmultimeter continuity⣠tests across engaged terminals
| Item | Description |
|---|---|
| Continuity â(closed) | Low resistance (near 0 Ί) between â¤common and selected terminal when the switchâ is engaged |
| Open circuit (disengaged) | No continuity between common and non-selected terminals |
| Visual evidence | contact pitting,burn marks,melted insulation,or carbon⢠tracking indicate electrical degradation |
Replacement Considerations,Compatible GE Models,and Installation Procedure for the⣠WB24T10145 GE Oven âŁBurner Switch
The WB24T10145 GE âOven Burner Switch⤠is a multi-position â¤selector designed to route mains power toâ an oven’s heating circuits or âŁcontrol the actuation of a gas valve in ranges that use electronic ignition. Internally it uses mechanical contacts and detents to provide discrete heat-setting positions; overâ time these contacts âŁcan oxidize or pit,causing intermittent⣠heating,loss of â˘specific â˘temperature settings,or a burner that remains energized. â˘When evaluatingâ aâ replacement, â˘match the electrical ratings⣠printed âon the original switch (voltage and⤠current), the ânumber and arrangement of spade terminals, the actuator shaft diameter â¤and lengthand any mounting flange dimensions so the new unitâ engages the⤠control knob and chassis⣠correctly.
Compatibility requires cross-referencing the oven’s model number and the OEM âpart number ârather than relying on visual â¤similarity alone; some GE and GE-owned-brand⣠ranges âŁuse the same switch family but with different shaft or⢠terminal layouts. For installation: disconnect all power at the âŁbreaker, âremove the âcontrol panel to âŁaccess âthe switch, photographâ and label each wire and terminal, âdisconnect â¤and test the old switch with âa multimeter toâ confirmâ open/short conditions,â then transfer wires to the replacement in the identical âŁterminal order, fasten the switch to the panel,â and verify operation with the power restored. Common practical checks include âconfirming continuity at each selector position and ensuring theâ knob âseats fully without binding.
- Key installation â¤checklist: powerâ off, document wiring, â¤confirm ratings, transfer âconnections, secure â¤mounting, perform continuity andâ functional tests.

Q&A
What is the⢠WB24T10145 and what does it do?
WB24T10145 is âan OEM âŁGE surface-burner controlâ (an “infinite” or âburner switch) usedâ on many GE/Hotpoint electric ranges. It â˘regulates⣠power to a cooktop surface element âand lets you vary heat by changing theâ contact position inside the⤠switch as you turn the knob.
What are common symptoms that⣠the â¤WB24T10145 has â˘failed?
Typical symptoms⢠include a burner that won’t heat at all, a burner thatâ remains on high or cannot be adjusted, intermittent operation (cycles on/off ârandomly), a â˘clicking/burning smell orâ obvious burnâ marks at the switchor the⣠knob position not matching⣠element temperature.⤠Visual damage and melted terminals are also âŁcommon signs of â¤failure.
How do I test the WB24T10145 safely with a multimeter?
Disconnect power to the rangeâ at the âbreaker. Remove â¤the knob andâ pull the switch out enough to access the spade⢠terminals; label or⤠photograph wiring first. Set a multimeter âto continuity or ohms. With the switchâ in OFF you⤠should see no continuity between the line and load terminals. Rotate the â˘knob through settings and you should âsee continuity âŁappear (or a change in resistance) between the line and âŁelement âterminals in ON positions. âAlsoâ check there is no continuity between any terminal and âthe chassis (no short to ground). If readings do not âchange as âthe knob movesor there is a short to ground, the switch is bad.
How many terminals does âthe WB24T10145 â¤have and âhow⣠are they â˘wired?
Different versions exist: many burner/infinite switches use three spade terminals â(line, âload/element,â and an indicator/pilot), while others use four.
