5303935086 Frigidaire Oven Top Burner⣠Switch Kit is a â¤replacement switch assembly used to control the⢠top⣠or surface burner circuits on electric ranges.It is indeed a mechanical-electrical⤠selector (commonly a rotary orâ “infinite” style switch) packaged with⣠the necessary mounting hardware âand terminals to replaceâ a worn â˘or failed control â¤on the cooktop. As a discrete control component, the kit interfacesâ directly with the element terminals and the user-facing control knob to regulate delivered power to the heating element.
inside the appliance the switch functions as theâ user-controlledâ disconnect and power-stepping âelement⣠forâ a single surface burner;â it makes⣠and⣠breaks âthe high-voltage âsupply to â¤the element and, depending on design, provides multiple power tap positions. It interacts withâ the â¤wiring harness, the element terminal block, the control console and âany â¤associated safety interlocks or temperatureâ limiters. Technically, the⢠switch â¤carries line voltage (nominally up to 240 â˘VACâ on two-wire ranges) and load currents for the element, so its contact integrity, terminal connections⣠andâ mounting are critical to reliable operation and to⢠avoiding⤠overheating or arcing⤠at the connectionâ points.
In this article you willâ find a technical explanation âof the part’s⢠function⣠and typical compatibility considerations, common failure⣠symptoms to âwatch for, stepâbyâstep troubleshooting methods⢠(continuity and live-voltage checks, terminal identification)andâ practical replacement considerations (correct part matching, terminal torque and insulation,â and⢠safe isolationâ procedures). Content is written for technicians, engineers⢠and experienced appliance owners who need to diagnose electrical control issues on âcooktops and to makeâ informed decisions about testing and installing this âswitch kit.

Function and Role of the âOvenâ Top Burner⣠Switch in Frigidaire Ranges
The 5303935086 âŁFrigidaire Oven âTop Burner Switch Kit serves as the electrical interface that controls power delivery to a range’s top burner âcircuit.â This âswitch assembly provides the operator-selectable contact closures that âroute mains power to the surface element or its⢠associated control circuitry; in âmulti-position switches it also selects different power⢠settings. In practice the switch is a mechanical contact device with âŁspecific terminalâ layout⣠and mounting dimensions,so replacement requires âmatching the⤠kit to the range model and⤠verifying terminal locations andâ connector types before installation.
- Common failure symptoms: burner will not heat, only heats intermittently, âŁor remains poweredâ when knob is released.
- Typical featuresâ to verify: terminal count⤠and orientation, rated for⢠line voltage,â and âincluded mountingâ hardware âor âharness.
- Diagnostic check: measure âŁcontinuity across the switch while actuating the control â¤knob; confirmâ expected contact routing for each position.
| Item | Description |
|---|---|
| Function | Provides â¤user-controlled contact⣠closures â¤to route⢠mains power to the âtop burner circuit |
| Behavior when faulty | Open circuit â¤(no heat), intermittent contact (cycling heat), â˘or welded contact (stuck on) |
| Compatibility notes | Match âpart number and terminal âlayout to the Frigidaire model; check âharness and mounting before replacement |
for technicians, the practical âapproach is to isolate the circuit andâ perform a continuity check across âthe switch while⢠simulating knob positions, then compare the â˘results withâ the range wiring diagram.Replace the switch only with a part that matches theâ original terminal mapping; improper terminal connections can route line voltage incorrectly or bypass safety interlocks. Always disconnect electrical â˘powerâ at the breaker and document connector positions or take a photo before removing the old switch âto ensure correct reassembly.
How the 5303935086 Frigidaire Ovenâ Top burner Switch Kit Works Inside the Appliance
The 5303935086 Frigidaire Oven Top Burner Switch âKitâ is an electromechanical control that routes mains power to âan individual surface element by âŁselecting amongâ a series of internal contact positions as â¤the â˘user turns âŁtheâ knob.Internally â˘the kit contains a rotary cam and multiple fixed contacts â¤or taps; ârotating the shaft closes âspecific contact pairs so the⢠supply terminal⢠is connected to the element load terminal in⤠discrete steps (low, âŁmedium, high, off).The⢠physical design uses standard spade â˘terminals⣠and a keyed â¤shaft and bushingâ so âthe part âmust⤠match the appliance’s terminal layout⣠and shaft dimensions to ensure⣠correct electrical routingâ and knob indexing.
The switch operates under mainsâ current and thus shows failure modes âconsistent with high-current switching: â˘contact wear or pitting causing increased resistance and heat at⢠terminals, intermittent open circuitsor â˘a⤠contact â˘that welds closed. For practical diagnosis,â verify presenceâ of â˘line voltage at the⣠supply terminal,â then turn the control and measure continuity or switched voltage to the element â˘terminal⢠across positions; disconnect⤠mains power before servicing. Typical replacement involves removing the knob and control panel, swapping the switch assemblyand ensuring tight spade connections⣠and correct shaft⣠orientation to â˘restore proper stepping behavior and safe operation.
- Symptoms to inspect: no heat, intermittent heating, stuck on/off, visible arcing or heat discoloration at terminals.
- Functional features: discrete contact taps for âstepped powerâ control, standard spade terminals, âŁkeyedâ shaftâ for knob alignment.
- Compatibility: must âŁmatch terminal arrangement and mounting bushing to avoid miswiring or misalignment.

Common Failureâ Modes and Diagnostic Symptoms for the Top⤠Burnerâ Switch Kit
The 5303935086 Frigidaire Oven⤠Top⣠Burner⤠Switchâ Kit is the user-replaceable assembly thatâ routes mains power to â¤the surface burners and provides the operator⣠control positions. In service this kit behaves â˘as a mechanical⣠switching â¤interface: each switchâ contact⤠closes to energize âa⣠burner circuit and opens âto remove power. Compatibility is steadfast by the terminal count,connector type and âmounting footprint,so technicians should verify the harness âŁplug orientation and the number of poles per switch against the âappliance wiring diagram beforeâ installation. â˘The â¤kit often replaces aged switches that have lost â¤positive contact,developed âcarbon tracking,orâ suffered heat âdeformation⤠near the oven opening.
- Burner fails to light or no voltage at⢠burner terminal
- Burner âŁremains energized whenâ control is off (stuck⣠closed)
- Intermittent operation or only works when âcontrols are jiggled
- Visible arcing, melted⣠plastic, burning odor at the switch area
- Excessive sparking atâ ignition âor delayed ignition tied⣠to switch position
| Item | Description |
|---|---|
| Expected continuityâ (closed) | Typically near 0-2 â¤ÎŠ for a âhealthy âŁclosedâ contact under no load⤠(use caution âŁand isolate powerâ first) |
| Expectedâ continuity (open) | High resistance or open âcircuit; any measurable leakage suggests carbon tracking or â¤contact wear |
| Connector/terminals | Rapid-disconnect spade terminals; confirm ânumber and spacing before replacement |
For â˘diagnosis, isolate power âŁand use a⣠multimeter âto check âŁforâ continuity and for any resistive paths thatâ indicate contact deterioration. Aâ common practical check is âŁto measure between the common and switched⤠terminal âwhile actuating theâ control: a properly functioningâ contact showsâ a â˘clean change from near-zero resistance to open circuit; a flaky or high-resistance readingâ frequently enough corresponds with intermittent heating or slow ignition. Visual inspection for heat damage, discolorationor melted housings is equally significant because thermal deformation changes contact pressure andâ alignment, producing symptoms⤠such as arcing or switches that stick; when these signs are present, â˘replacing the entire 5303935086 kitâ and ensuring proper terminal seating â¤typically restores reliable operation.
Compatibility, Replacement âConsiderationsand Installation Procedures
The⣠5303935086 Frigidaire Oven Top Burner Switch Kit is the user interface â˘and electrical switching component that controls the power âdelivered to a cooktop surface burner. The switch provides discrete heat positions by opening⤠and closing internal contacts (or switching through resistive âelements⣠in an infinite-style control), which modulates current to the element; worn contacts, internal shortsor damaged shafts⢠produce âsymptoms such as loss of specificâ heat settings, intermittent heatingor a burner âthat stays âŁenergized. Compatibility is determined by terminal arrangement, shaft type (splined or smooth), mounting flange âgeometryandâ the â¤appliance’s supply voltage, so mechanicalâ and â¤electrical mating details must match for proper operation rather âŁthan relying solely on part number cross-references.
- Verify OEM numberâ and visually match terminal count âand mounting before ordering.
- Disconnect power, then photograph orâ label each â¤wire to preserve terminal mapping during replacement.
- Check shaft diameter and knob fit; some models âuse splines or âkeyed shafts that are⢠not âinterchangeable.
- Afterâ replacement, test continuity across âterminalsâ at each knob position âand observe element cycling under live⤠conditions.
| Item | Description |
|---|---|
| Function | Selects heat level and connects/disconnects current to â¤the top burner |
| Typical connections | multipleâ spade terminals; terminalâ count varies by model-confirmâ visually |
| Mechanical â¤fit | Mounting flange dimensionsâ and shaft style must match appliance knob and bezel |
Replacement considerations emphasizeâ safety and dimensional verification: confirm the kit matches⢠the cooktop’s âŁelectrical âŁrating and that the â¤switch body â¤aligns with the existing âmounting âpoints and knob geometry. Installation procedureâ is straightforward for a competent technician-isolate power, remove access panel, ânote or â˘photograph âwiring, remove the old switch, transfer wires to identically⤠labeled terminals âon the new switch, secure⤠the kitand reassembleâ panels; perform a continuity and functional test across âsettings and observe the burner under normal operation to validate the repair. Ifâ anomalies persist after a correct mechanical andâ wiring installation, inspect âŁthe element, harnessand control circuitry for⤠secondaryâ faults before returning the appliance â¤to service.
Q&A
What is⤠theâ 5303935086 Frigidaire Oven Topâ Burner Switch Kit⢠and what âdoes it do?
The 5303935086 is aâ replacement switch kitâ used âon many Frigidaire (andâ related brand) electric â˘ranges. â¤It⢠contains the control âŁ(an “infinite” or burner switch)⢠and mounting hardware that sit behind âthe surface burner controlâ knob. âThe switch cycles power to a surface heating element toâ change heat levels and hold the selected setting.
What symptoms indicate this switch kit needs to be⤠replaced?
Common⢠signs of a failing burner switch include a surface burner that â˘won’t heat âat all,a âŁburner that is stuck onâ a singleâ heatâ level⣠or cycles â˘unpredictably,intermittent heating,burning or melting smell near the control,visible damage to the âŁswitch,or scorched/melted terminals behind â¤the âknob.
How do I⣠confirm this part⣠is compatible with my Frigidaire range?
Check your range’s â˘model numberâ (usually on a tag âŁinside the⣠ovenâ door frame or on âthe back of the range) â¤and compare it to theâ parts list or online parts diagram for thatâ model. Also remove the control knob and â˘inspect the old switch for a part number. If âin doubt, consult the⣠appliance’s parts fiche or contact Frigidaire/parts supplier with your range model to⣠confirm compatibility.
Can I replace the switch kit myself and what tools are required?
Yes, a competent DIYerâ or technician can usually replace⢠the switch. Required tools are typically a screwdriver and/or nut driver⣠set, needle-nose pliersand optionally a âmultimeter. âAlways disconnect the range from power at the breakerâ or âunplug itâ before â˘starting,⣠remove the controlâ knobs and âcontrol panel or back access â˘panel, label â˘wires, remove mounting screws, swap switches, reattach wires exactly as removed,⢠and reassemble. If you are uncomfortable working around live electrical⢠circuits, â˘hire a â¤qualified⢠technician.
How can I test the burner switch before replacing it?
With⢠the⤠power disconnected and the switch removed⤠or accessible, use a multimeter to⣠check continuity â¤between the common terminal and âŁthe selector terminals while rotating⤠the controlâ through itsâ settings;â continuity should change as the knob is rotated. If you’re âexperienced âŁand take proper safety precautions, youâ can also carefully measureâ for voltage at the â˘switch terminals with power on to confirm it’s not switching â¤line âvoltage to the element-but this should only âbe doneâ by someone âcomfortable working with live electrical circuits. If the âŁswitch shows no change inâ continuity or has open or⣠shorted terminals, it shouldâ be âreplaced.
Is âthe burner â˘switch kit the same as the ovenâ thermostat or oven âtemperature control?
No. The surface burner (infinite) switch controls power to the cooktop surface elements. The oven â¤thermostat or oven âŁtemperature â¤sensor and control are separate âŁcomponents that govern oven temperature. If your oven (not the surface burners)â isâ not heating properly, âreplacing the surface burnerâ switch will not fix that; you’ll⤠need to âdiagnose the â¤oven control, bake element, âŁtemperature sensoror⤠related âcomponents.
What commonly âcauses⢠these switches to fail?
Typical âfailure modes areâ wear â˘from repetitive cycling,heat damage from nearby elements or spilled liquids,arcing at terminals resulting in⢠burned connectors,mechanical wear of â¤the selector mechanism,and corrosion⣠fromâ moisture or cleaners.Loose or damaged â¤wiring and poor âelectrical contact⣠can accelerate âŁfailure.
What does the kit usually include and is there a warranty?
Kit contents⢠vary by â¤seller but commonly include the replacement switch assembly,mounting⤠bracket or screws,and sometimes âaâ knob or wiring harness clip. OEM kits will clearly list included items; aftermarket kits may differ. Warranty coverage depends on the â˘supplier or manufacturer-OEM parts often carry âŁa limited parts warranty (check the âseller’s listing or Frigidaire documentation). Always âverify what’s included and⢠the âwarranty before purchase.
