WB24T10058 GE Oven Surface Element Switch is a line‑voltage control switch used to regulate electrical power to a surface heating element on GE electric ranges and cooktops. As an electromechanical switching component, it is designed to accept user input via the range control knob and modulate current to the element either continuously or in a duty‑cycled fashion depending on the switch design and setting.
Inside the appliance, the surface element switch sits between the incoming mains supply and the surface heating element, and it interfaces directly with the element terminals, the range’s wiring harness, and the front‑panel control interface. It therefore plays a direct role in temperature control and user feedback: by opening and closing or varying power to the element it influences element temperature, interacts with adjacent control circuits (indicator lights or electronic control modules), and must tolerate full line voltage and high current loads typical of heating elements.
In this article you will find a clear description of how the WB24T10058 functions, guidance on identifying compatible replacements and checking part markings and terminal layout, typical failure symptoms (no heat, intermittent operation, element stuck on, burnt contacts), practical troubleshooting steps using a multimeter and safe isolation practices, and key replacement considerations such as matching voltage/current ratings, mounting orientation, and connector types. The data is presented for technicians, engineers, and appliance owners who need a technical understanding of the component’s role, diagnostic approach, and installation requirements without assumptions about prior familiarity with this specific part number.

Function and Role of the Surface Element Switch in GE Electric Ranges
The WB24T10058 GE Oven Surface Element Switch is a mechanical control commonly referred to as an “infinite” or surface element switch that regulates the amount of line voltage delivered to a cooktop element by modulating contact closure time.Mounted behind the control knob, it provides stepped or variable heat settings by switching the heating element on and off in controlled duty cycles rather than sensing element temperature. Typical failure modes include contact pitting from arcing, melted housings from excessive heat, and broken actuator mechanisms; these failures manifest as elements that do not heat, heat intermittently, remain energized regardless of knob position, or produce visible sparking and burning odors.
Verify compatibility with the appliance by checking terminal arrangement, mounting flange, and electrical rating before installing a replacement. For diagnosis, measure incoming line voltage at the switch with the control set to an on position and check continuity between common and load terminals across settings; significant resistance or intermittent continuity under load indicates degraded contacts and necessitates replacement. For safety and reliable results, disconnect power before disconnecting wires, label or photograph wiring, use the correct spade connector sizes, and avoid reusing visibly damaged switches-cleaning contacts can be a temporary measure but replacement is the long-term fix for pitting or thermal damage.
- Symptoms: no heat, intermittent heat, stuck on, arcing or burning smell
- Common checks: verify line voltage, continuity across settings, inspect terminals for burns
- installation notes: label wires, use proper connectors, tighten to avoid high-resistance joints

How the WB24T10058 GE Oven Surface Element Switch Operates Within the Range’s Electrical and Control Circuits
The WB24T10058 GE Oven Surface Element Switch functions as the user-facing power selector that connects and modulates line voltage to a surface heating element. In most installations this rotary switch provides multiple contact positions that either apply full line voltage to the element or cycle the circuit on and off to produce intermediate heat settings; the contacts themselves carry the full cooktop current and are designed to match the mechanical and terminal layout of the OEM assemblies for direct replacement. In practice, the switch routes the incoming L1/L2 supply to the element terminal(s) and ofen includes an additional terminal for the indicator lamp, so correct terminal mapping is a critical compatibility check during replacement.
Within the range’s electrical and control circuits the switch operates as the primary local control for element power on manually controlled models, and as a high-current interface component on electronically controlled ranges. on simpler analog ranges the switch directly provides stepped or infinite power by sequentially selecting contact paths; on ranges with central control boards the board may only enable or monitor the element while the switch determines the power level, or conversely the switch may supply voltage that the board modulates via relays or solid-state devices. Practical technician checks include verifying continuity across the switch positions, confirming rated line voltage at the incoming terminals, and noting failure modes such as no-heat, continuous-heat (stuck contacts), or intermittent heating caused by pitted contacts or poor terminal connections.
- Electrical behavior: connects or cycles line voltage to the element to regulate average power.
- Control interaction: may act independently or work with the control board depending on range design.
- Compatibility checks: confirm terminal layout, mounting pattern, and current rating before replacement.
- Common symptoms of failure: no heat, element stuck on, intermittent operation, and visible contact wear.

Common Failure Symptoms and Measured Electrical Indicators of a faulty Surface Element Switch
The WB24T10058 GE Oven Surface Element Switch is a rotary contact device that routes line voltage to a surface heating element according to the selected control position. Technically, the switch closes specific internal contacts to feed the element and may present either a direct closed contact (near-zero resistance) or stepped resistive paths depending on the control design. When replacing or diagnosing this switch, match terminal layout and mounting orientation because incorrect wiring or a mismatched physical layout can leave the element unpowered, intermittently powered, or permanently energized; the switch itself does not regulate temperature, it simply connects or disconnects the element circuit according to the chosen setting.
Common failure modes produce distinct electrical signatures that are measurable with a multimeter or insulation tester. Typical indicators include an open circuit (OL) between the switch terminals for positions that should be closed, unusually high contact resistance that causes weak heating, intermittent continuity that correlates with erratic heating behavior, or low resistance to chassis ground indicating a short. For practical troubleshooting, isolate power, disconnect the switch from the harness, and compare measured continuity and resistance against expected closed/open conditions to determine whether the switch or wiring is at fault.
- Burner no heat: open circuit (OL) between input and output terminals when a closed position is selected.
- Burner always on: continuity present to the element in all switch positions,or low resistance to chassis ground.
- Intermittent or weak heating: fluctuating continuity or elevated contact resistance (noticeably above a few ohms).
- Breaker trips or sparks: very low resistance to ground or short between live terminals.
| Item | Description |
|---|---|
| Open circuit (no heat) | Multimeter reads OL between input and output terminals in positions that should be closed. |
| High contact resistance | Closed position reads significantly above a few ohms (e.g., tens to hundreds of ohms), causing weak or slow heating. |
| Short to ground / always on | Low resistance to chassis or continuity across terminals in all positions; causes continuous heating or tripping. |
Compatibility, Replacement considerations and Step‑by‑Step Installation for Surface Element Switches
The WB24T10058 GE Oven Surface Element Switch is a rotary, multi‑position control that modulates power to a cooktop element by routing mains voltage through different contact paths. Functionally it operates as an “infinite” or stepped power switch rather than an electronic regulator: rotating the shaft selects which internal contact is energized to vary heat. Compatibility depends on physical and electrical matches – terminal type and layout (fast‑connect spades), shaft diameter and spline, mounting flange and nut thread, and the switch’s voltage/current rating relative to the oven circuit. some GE ranges share the same part number across model years, but differences in knob spline length or control panel cutouts can require a different switch or a knob adapter for proper fit and operation.
- Disconnect power at the breaker and verify zero voltage with a meter before touching wiring.
- Document or photograph wire positions,then remove the control panel access and loosen the retaining nut to free the switch.
- Carefully transfer spade connectors to the replacement in the same order, ensuring firm, corrosion‑free contact.
- Reinstall the switch, secure the knob and panel, restore power, and test each heat setting for proper element response and absence of arcing.
Replacement considerations include checking terminal labeling (common/load/supply), ensuring the new switch’s shaft geometry matches the knob, and confirming the electrical rating matches the appliance wiring. after installation, verify operation with the element removed from contact or at a reduced duty cycle if possible; use a multimeter to confirm continuity between common and stepped outputs as the knob rotates, and visually observe element behavior during each setting. If the control panel requires rework to accommodate a different flange or spline, factor that into repair time and parts required.

Q&A
What is the WB24T10058 and what does it do?
The WB24T10058 is an OEM surface-element control (often called an “infinite” or surface element switch) used on many GE/hotpoint electric ranges.It controls the amount of power sent to a specific cooktop burner by varying the duty cycle (on/off time) as you turn the knob, allowing low to high heat settings.
What are common symptoms that the WB24T10058 has failed?
Common symptoms include a burner that won’t heat at all, a burner that stays on and won’t turn off, only certain heat settings working (e.g., low works but high does not), intermittent or erratic heating, visible burning or melting on the switch, or arcing/clicking sounds when the control is used. always confirm the element and wiring are good before replacing the switch.
How do I safely test the WB24T10058 with a multimeter?
First, disconnect power at the breaker. Remove the knob and access the control from the back of the console. Identify the switch terminals (consult the range wiring diagram). With a multimeter set to continuity or ohms, check that continuity between the line and load terminals changes as you move the knob through settings (off should be open). Also check for continuity/short to ground-there should be none.If the switch shows no change across positions, or is shorted to ground, it is indeed likely bad. Do not perform tests with power applied.
How can I tell if the problem is the switch or the surface element itself?
Visually inspect the element and its socket for damage or discoloration. With power off, remove the element and measure its resistance-most working elements will show a low resistance value (they are not open). If the element measures open (infinite resistance) it is bad. If the element is good but no power reaches it when the switch is turned on, the switch or wiring is highly likely at fault. You can also check for incoming voltage at the switch terminals (with power on and proper safety precautions or by a qualified technician) to trace where power is lost.
Is the WB24T10058 a direct replacement for my GE range?
That depends on yoru exact GE/Hotpoint model. WB24T10058 is a specific OEM part and will replace the original switch only when the connector layout,mounting style and electrical ratings match your appliance. Always look up parts by your full appliance model number or consult the GE parts diagram to confirm compatibility. If in doubt, compare the physical switch and terminal positions before ordering.
What are the basic steps to replace the WB24T10058?
Turn off power to the range at the breaker. Remove the control knob and the back access panel to expose the switch. Take a clear photo or label each wire so you can reconnect them correctly. Disconnect the spade connectors, remove the mounting screw(s), and swap in the new switch. Reconnect wires, reassemble the console, restore power, and test the burner. If you’re not pleasant working around live circuits, hire a qualified appliance technician.
Do wire colors or terminal labels matter when replacing the switch?
Yes-wire function is persistent by terminal position,not color,and colors can vary across models and repair histories. Always label or photograph connections before removal and refer to the wiring diagram on the range. Many switches have terminals labeled (line, load, hi, lo, or for the indicator light); reconnect each conductor to the same terminal on the new switch.
Where should I buy a replacement WB24T10058 and is there a warranty?
Buy from authorized GE parts dealers, reputable appliance parts retailers, or directly from GE/Whirlpool-authorized vendors to ensure you receive an OEM part. Aftermarket alternatives exist but confirm fit and electrical ratings.Warranties vary by seller-OEM parts commonly have a limited warranty (frequently enough 90 days to one year); keep your purchase documentation and check the seller’s warranty terms before buying.
In Summary
The WB24T10058 GE Oven Surface Element Switch is a key control component that regulates power to the cooktop heating elements. Its proper function ensures consistent heat delivery, accurate surface-temperature response, and safe operation of the range. Because the switch directly influences both performance and user safety, its condition has a meaningful affect on cooking results and on the long-term reliability of the appliance.
Timely and accurate diagnosis-confirming that the switch is the source of a symptom rather than another component-followed by replacement with the correct, compatible part when necessary, helps restore normal function and reduces the risk of further damage or safety hazards. When repair is required, using the specified part number and following appropriate service procedures (or consulting a qualified technician) preserves appliance performance and safety while minimizing repeat failures.
