WB24T10058 GE Oven Surface Element Switch is a surface element control switch used in many GE electric ranges and ovens.It is a rotary selector (often called an infinite or surface element switch) that provides discrete or stepped regulation of electrical power to a cooktop surface heating element and serves as the user-operated interface behind the control knob.
Inside the appliance the switch routes mains voltage to a specific surface element contact based on the knob position, cycling or varying the applied current to achieve different heat settings. It directly interfaces with the cooktop element terminals, the range wiring harness, and the front control panel; it also carries the full operational current for the element and must match the appliance’s voltage and current ratings. Failures or contact wear in this switch can produce no-heat, intermittent heat, or unintended continuous heating, so it is a critical component for proper temperature control and safe operation of the cooktop.
In this article readers will find a technical overview of the WB24T10058’s function and construction, guidance on compatibility and how to verify correct part fit (electrical rating, terminal layout, and mechanical mounting), common symptoms of failure, high-level troubleshooting checks a technician can perform, and practical replacement considerations such as safety precautions, connector verification, and OEM versus aftermarket selection. The goal is to provide the technical context needed to diagnose switch-related cooktop issues and make an informed repair decision.

Function and Role of the Oven Surface Element Switch in power Regulation and Safety Controls
The WB24T10058 GE Oven Surface Element Switch is a rotary infinite-style switch that regulates the heat output of a cooktop surface element by altering the element’s effective duty cycle and by selecting different connection taps on the element circuit. Inside the enclosure an electromechanical mechanism and a temperature-sensitive element modulate power: lower knob positions produce short on/off cycles to reduce average wattage, while higher positions lengthen on-time toward continuous power. In many installations the switch also provides a terminal for an indicator light and uses standardized spade terminals and mounting points so the electrical and mechanical interface matches the original equipment.
Beyond power regulation, the switch serves as a basic safety control and a serviceable failure point: it interrupts current under faulted or open conditions, and abnormal contact wear or a failed sensing element can produce symptoms that indicate replacement is necessary. Technicians should confirm correct terminal layout, detent positions, and mechanical fit when choosing a replacement to ensure the same thermal and electrical behavior; incorrect substitution can lead to overheating, persistent on-state, or no-heat conditions. For practical troubleshooting, common observable features and failure cues include:
- Multiple calibrated power positions (detents) providing stepped duty-cycle control.
- Standard spade terminals and an indicator-light terminal for easy replacement and diagnosis.
- Failure symptoms: element stuck on, no heat, intermittent heating or rapid cycling.

How the WB24T10058 GE Oven Surface Element Switch Works Inside the Appliance (Electrical Path,Contacts,and Control Interface)
The WB24T10058 GE Oven Surface Element Switch is a multi-position mechanical selector that directly routes the cooktop mains to the surface element via discrete internal contacts. Inside the assembly the rotating shaft engages a set of stamped or laminated contact wafers so that each detent connects the incoming line to one or more output terminals; some positions provide full line voltage while intermediate positions route the circuit through additional contact paths that reduce power to the element.The control interface is purely mechanical on most compatible GE ranges- the user knob physically turns the switch shaft-so correct electrical behavior depends on intact contact faces, proper terminal wiring, and matching current/voltage ratings for the appliance model rather than any software configuration.
Fault behavior and practical diagnosis focus on the electrical path and contact condition: common symptoms are no-heat, only full-power or only certain settings functioning, intermittent heating, or visible arcing at terminals. A basic technician workflow is to isolate power, remove the knob and harness, and use a multimeter to check continuity across the common and each position while rotating the shaft; excessive resistance or an open where continuity should exist indicates worn or burned contacts. Confirm compatibility before replacement by matching terminal layout, mounting holes, and amp/voltage rating to the appliance wiring diagram; such as, if low- and medium-power positions fail but high works, the switch’s lower-contact wafer is likely degraded and replacing it with the correct WB24T10058 GE Oven Surface Element Switch assembly is the practical remedy.
- Quick checks: visual contact inspection, continuity by position, element resistance check, verify correct harness/terminal mapping.
| Item | Description |
|---|---|
| Line (L1) | Main supply input to the switch |
| Load (Element output) | Terminal(s) that feed the surface element depending on position |
| Selector positions | Discrete contact wafers that establish power level |
| Mounting / Rating | Physical mounting pattern and amp/voltage spec to match the range |
Common Failure Symptoms and Diagnostic indicators of Surface Element Switch Malfunction
the WB24T10058 GE Oven Surface Element Switch serves as the user-facing control that connects mains voltage to an individual surface element through a set of internal contacts or an infinite-control mechanism. In normal operation the switch directs line voltage to the element terminals according to the knob position,providing stepped or variable heat. Compatibility-wise, the switch must match the oven’s line and load terminal arrangement and mounting, and its contact ratings must meet the element current; mismatched terminals or an underrated switch will produce intermittent operation, overheating at the connection points, or premature failure.
Typical failure modes manifest as predictable electrical and mechanical symptoms that simplify diagnosis for a technician. Use a digital multimeter to perform static checks: verify element continuity to rule out the element itself, confirm supply voltage present at the switch common terminal with the knob actuated, and measure resistance between the switched output and common across several knob positions to confirm consistent transition. Also inspect the switch body and harness for thermal discoloration,melted insulation,or pitted/burned terminals,which indicate arcing or high-resistance contact. Practical examples: a burner that only heats on high suggests degraded low-range contacts; a burner that remains energized after turning the knob indicates stuck or welded contacts.
- No heat on a specific burner – check element continuity first,then switch output terminal for voltage.
- Intermittent heating – inspect for loose or corroded terminals and measure contact resistance across positions.
- Burner stuck on – look for welded contacts or mechanical binding inside the switch.
- Visible arcing, burning smell, or discolored housing - replace switch and repair/replace damaged wiring.
| Item | Description |
|---|---|
| Symptom: No output voltage | Test with meter at switch output with knob engaged; if no voltage but supply present, switch contacts failed. |
| Symptom: Limited range (only high) | Measure resistance across terminals at low settings; high or open readings indicate worn low‑range contacts. |
| Symptom: Arcing or heat at terminal | Visual/thermal inspection; replace switch and correct terminal connection torque and wiring damage. |
Compatibility with GE Models, Replacement Considerations, and Safe Installation Procedures
The WB24T10058 GE Oven Surface Element Switch is an electromechanical control that regulates line voltage to a surface heating element by switching and modulating current through multiple detent positions. Functionally, it replaces the user knob and provides stepped power levels to the coil; compatibility depends on matching the switch’s electrical rating, terminal arrangement, shaft style, and mounting footprint to the original component. Before replacing, compare the oven’s wiring diagram and the switch’s rating plate or datasheet: the correct replacement must have the same voltage and current capability and identical spade-terminal layout (or an adapter) to prevent overheating, poor contact, or nuisance tripping. Note that ranges that use solid-state control modules, induction elements, or digital touch controls use different control architectures and will not accept this type of mechanical surface element switch.
Installation and troubleshooting require basic electrical skills and careful verification. Isolate the appliance at the breaker, document and label every wire location, then verify continuity and contact behavior across detents with a multimeter to confirm the new switch operates as was to be expected. After mechanical fit and wiring are confirmed, reassemble and perform a staged functional test (low to high settings) while observing for abnormal heating, arcing, or loose connectors; if the switch or element shows overheating or intermittent contact, stop and recheck terminal tightness and compatibility. For long-term reliability, always use an OEM or equivalent replacement specified for the appliance model and follow the manufacturer’s torque and mounting recommendations to ensure consistent contact force and thermal performance.
- Isolate power at the breaker and verify with a meter before touching terminals.
- Match terminal count and layout; label wires/photo before removal for accurate reassembly.
- Verify switch voltage/current rating against the oven wiring diagram or service manual.
- Test continuity across detents and perform low-to-high functional tests after installation.

| Mounting | Shaft diameter and panel footprint-ensure the replacement aligns with bezel and knob fitment. |
| Electrical verification | Confirm voltage/current ratings and test continuity across positions before full restoration of power. |
Q&A
What is the WB24T10058 and what does it do?
The WB24T10058 is a replacement surface element (infinite) switch used on many GE/Hotpoint/Whirlpool-style electric ranges. It controls the power delivered to a cooktop surface element by switching/cycling the circuit at different positions on the knob to regulate heat from low to high.
What are common symptoms that the WB24T10058 is failing?
Common signs include an element that won’t heat at any setting, an element that stays on full power or won’t turn off, erratic or intermittent heating, a knob that doesn’t click or feels loose/sloppy, visible burning or melted plastic around the switch enclosure, and an indicator light that won’t work when tied to that switch.
How do I test the WB24T10058 with a multimeter?
Always disconnect power at the breaker first. Remove the knob and access panel to expose the switch. Identify the line (power), load (element) and any pilot/indicator terminals.With the meter set to continuity or ohms, check between the line and load terminals while rotating the switch through several settings-continuity should change according to the positions (open at off, make/break at other settings). Also check continuity to the pilot terminal if your model uses one. If continuity behavior is inconsistent with the position or there is no change at all, the switch is highly likely defective.
Can I replace the WB24T10058 myself, and what are the basic steps?
Yes, an experienced DIYer or technician can replace it. Basic steps: disconnect power at the breaker, remove the control knob and any trim or back panel to access the switch, photograph or label all wire connections, disconnect wires, remove mounting screws, install the new switch, reconnect wires exactly as labeled, reassemble trim, restore power, and test. If you’re not comfortable working with live electrical components, hire a qualified technician.
Are there common wiring differences or gotchas I should watch for when replacing this switch?
Different models can have slightly different terminal arrangements; some switches include a terminal for the cooktop indicator light while others do not. always label or photograph wiring before removal and match wires to the same terminals on the new switch. Also verify the replacement matches the shaft length and mounting pattern; some ranges use different shaft styles or a terminal adapter. Do not assume wire colors always correspond to the same terminal-confirm by position.
How do I know if WB24T10058 is compatible with my oven or cooktop model?
Check your appliance model number (usually on the oven frame, door edge, or behind a drawer) and cross-reference it with the part number using the manufacturer’s parts list, a trusted parts website, or the retailer’s compatibility lookup. Many parts lists will show WB24T10058 as OEM for multiple GE/Hotpoint/related models, but always verify fit and terminal layout before purchase.
What causes these switches to fail and how long do thay typically last?
Failures are usually caused by normal mechanical wear from repeated switching,heat damage from high temperatures or a failing element,arcing at contacts,or contamination (grease,food). Lifespan varies widely with usage and heat exposure-many last years but heavy use or overheating shortens life. Visible carboning or pitted contacts when inspected indicates failure.
what is the approximate cost and are aftermarket parts OK?
OEM WB24T10058 switches typically cost in the low tens of dollars (often around $15-$40 retail) though prices vary. Aftermarket equivalents are available and often less expensive; they can work fine if they match the electrical ratings, shaft style, mounting holes, and terminal layout. For long-term reliability choose a reputable supplier and confirm electrical ratings and fit before installing.
In Summary
The WB24T10058 GE Oven Surface Element Switch serves a critical role in controlling power to the surface heating elements, regulating heat delivery and enabling accurate temperature control for cooking tasks. As a functional interface between the user controls and the element, a properly working switch is essential to maintain appliance performance, energy efficiency, and predictable cooking results.
Because symptoms of a failing surface element switch can mimic other issues, accurate diagnosis is important to avoid unnecessary parts replacement and to ensure safety. Replacing a defective WB24T10058 when testing and inspection indicate it is indeed the root cause can restore reliable operation, prevent further component stress, and reduce the risk of electrical faults or uneven heating.
