Functional Role⤠and âElectrical Specifications of the Oven âsurface Element Switch
The 318293827 âŁFrigidaire Oven Surface Element Switch is a multiâposition rotaryâ contact assembly that controls the amount of line voltage delivered to a cooktop surface element. It accomplishes⣠power regulation⢠by â˘switching among âdiscrete contact âŁtaps or by cycling contacts to âproduce averaged power⢠levels; this approach provides stepped heat settings without requiring electronic⢠speed⤠control.Compatibility is determined by the switch’s terminal âlayout,mounting flange,and the stamped electrical ratings-replacing⤠the switch requires âan exact match or a mechanically and electrically equivalent unit toâ avoid overheating âor improper operation.
Typical electrical⣠characteristics you will encounter on⣠this class of switch include âline-voltageâ operation (120/240 VACâ depending on range design) and continuous current ratings commonly in the 15-40 A range; alwaysâ verify the rating on the original â˘part before âŁreplacement. Technicians â˘diagnose switch faultsâ by measuring continuity â¤and resistance across theâ element/load terminals at eachâ knob âposition, observing for⢠open circuits,⢠intermittent connectionsor arcing; visible discoloration orâ melted insulation at terminals also indicates replacement â¤is required. practical troubleshooting examples include a burner that receives voltage at the switch input but shows noâ continuity at⣠the load (failed contact) or a burner âthat only heats âon⣠the highest â˘setting (worn lowâpower taps).

How the 318293827 frigidaireâ Oven surface Elementâ Switch Operates Within âthe Cooktop â¤Control Circuit
The 318293827 Frigidaire Oven⤠Surface Element âSwitch is⤠a rotary “infinite” control âmounted behind the âŁcooktopâ knob that regulates mains power to a⢠surface heating element. Internally it provides stepped contact positions and âan adjustable heater/bimetal or resistive âtiming â¤element so the switch does notâ simply select discrete â˘voltagesâ but modulates duty cycle:â higher knob settings close the âcontactâ continuously for⢠full power, âwhile lower settings use the internal heater and bimetal action to open and close theâ circuit âŁintermittently, producing âŁan effective lower average âŁpower toâ the â¤element. In practical terms the switch routes one â˘or⤠both âŁhot lines to the element terminal(s) â¤depending âonâ cooktopâ design, so â¤correct electrical rating and terminal layout must match the⣠oven model to ensure safe and reliable operation.
Technicians diagnosing âcooktop issues will observe âthat failed or âŁdegraded switches cause â¤specific behaviors-no â¤heat, intermittent âheator â˘an element stuck on âat a⤠single setting-and can be â¤isolated withâ visual inspection âfor arcing, a continuity âcheck âacross⢠terminalsand verifying switching âactionâ while âoperating the âŁknob (power removed⣠where required for safe testing). Typical characteristics and diagnostic cues include:
- Continuous âconduction â˘at all knob â˘positions (stuck contact)
- Open âcircuit on all positions (failed contact/connector break)
- arcing or heat damage âat spade terminals â(mechanical/thermal failure)
For⤠replacement, confirmâ terminal labeling and current/voltage ratings match the cooktopâ wiring schematic; the correct âpart will reproduceâ the same line/load/indicatorâ connections and duty-cycle behavior âused by the âoriginal⢠control.
| Item | Description |
|---|---|
| Lineâ (L) | Supply lead(s) from the cooktop power source; provides⤠mains input âto the switch |

Common⢠failure Symptoms, Measuredâ Fault Indicators,⤠and Criteria for Switch Replacement
The â318293827 Frigidaire âOven Surface⤠Element Switch is a âmulti-position, mains-voltage selector that routes power to an individual surface â¤element and modulates heat by âswitching âresistive tap points. Inâ normal âoperation the switch presents ânear-zero resistance âbetween theâ incoming line andâ the â¤chosen output terminal when in an active position,⤠isolatesâ the circuit in OFF⣠positionsand maintainsâ secure mechanical contact under load.Compatibility checks shoudl confirmâ that the switch’s terminal layout and voltage/current rating âmatch the range model âŁbefore replacement; mismatched terminal â˘mapping or lowerâ current â˘ratings can produceâ overheating, poor âregulationor premature failure. Typical â¤failure behaviors a technician will observe include an element that does âŁnot⢠heat âŁat some or all settings, erratic temperature (intermittent contact),â continuous element heat when the control is turned off, visible arcing at âthe terminalsor melted insulation at the connector.
- noâ continuity in positions âthat should be âŁclosed âŁ(open circuit under multimeter).
- Highâ closed-circuit⢠resistance compared with a known-good switch (typical⢠replacement threshold:â several ohms, depending on⢠design).
- Intermittent continuity whenâ rotating the shaft â˘or âactuating the switch.
- Insulation breakdown or continuity to chassis/ground indicating âleakage.
- Visible â˘thermal damage, âdiscolorationor deformed terminals.
Measured fault indicators that justify replacement include⤠an openâ circuit measured in any ON position, a fluctuating continuity reading⤠under âmechanicalâ actuationor⤠a closed-circuit resistance markedly higher than the â¤factory characteristic (which⢠will reduceâ element wattage and âcause improper heating).Use a digital multimeter âŁto check continuity and measure resistance â¤across the appropriate pair of âterminals for each dial âŁposition;⤠perform an insulation⣠resistance â¤test if there are signs of arcing or burnedâ insulation. Replace âthe switch when any ON position is open,â protection/ground integrityâ isâ compromised,⢠terminals show âheat damageor when intermittent readings appear-these conditions indicate unreliable contact or internal âarcing that cannot be correctedâ by cleaning and create safety â˘and performance risks.
| Item | Description |
|---|---|
| Closed-circuit resistance | Should be near zero ohms for a healthy contact; elevated resistanceâ reducesâ element power. |
| Intermittency | Fluctuating⢠continuity during shaft rotation indicates worn or pitted contacts and warrants âreplacement. |
| Insulation/ground | Any continuityâ toâ chassis â¤or visible âinsulation damage âŁrequires replacement for safety. |
Model Compatibility, Replacement Considerationsand âŁProfessional Installation⣠Checklist
The â¤318293827 Frigidaireâ Oven Surface Element Switch⤠is a multi-positionâ selector that routes mains power to a cooktop element and â˘provides discrete âheat settings by âswitching between internal contactâ paths. In operation âthe switchâ conducts full line voltage through selected poles and mayâ be implementedâ as â¤a single- or multi-pole,⣠multi-throw rotary or detented selector; common failure modes include loss of âcontinuity toâ the element, intermittent heating, visible arcing at the terminalsor a knob that no longer engages âŁdistinct⤠positions. âProper compatibility requires matching the electrical rating (voltage and continuous current), pole-and-throw configuration, âterminal type and⣠spacingand the mechanical dimensions (shaft length, mounting flangeand knob fit) so the replacement reproduces original contact⢠sequencing â¤and thermal performance.
Replacement and installation should treat the switch as a live-line control subject to âhigh âcurrent âand elevated temperatures.

Q&A
what is â¤part â318293827 and âwhich Frigidaire ovens or â¤cooktops does âit fit?
Part 318293827 is an OEM surface element (infinite) switch used â¤to âŁcontrol the â¤heat level of a â¤surface heating element on select Frigidaire ranges and cooktops. It fits specific âmodels âonly – compatibility âvariesâ by model/year. Always verify fit by checking⣠your appliance model number (usually on a tag inside the oven door frame â¤or behind the broilerâ drawer)⢠and comparing to âthe parts diagramâ on â¤Frigidaire’s parts⣠site or an⣠authorized parts supplier before ordering.
What common symptoms indicate âthe surface element switch is failing?
Common signs⣠include a burner that won’t heat at any setting, only works on one orâ two settings,⢠cycles erratically, gets stuck on a â˘single power level, causesâ arcing or sparking⣠at the knob/wiringor produces a burning smell. â¤If the âelementâ itselfâ is known-good (tested separately) and wiring/connectors âare intact, the⣠switch is⣠a likely culprit.
How doâ I safely test the surface âelement switch with a multimeter?
Safety first: disconnect â˘power at the⣠circuit breaker before any testing.Remove â¤the control⣠knobâ and access the âswitch (console âŁor rear âŁpanel). With the âmultimeter set to continuity or resistance (ohms), check for continuity between the common/input terminal âŁand the load/outputâ terminal while rotating the switch through settings. An infinite/variable switch will show changing resistance or continuity in ON positions and open/infinite resistance in⢠OFF. If the switch remains⤠open in all ON positions or shorts in OFF, it’s⤠faulty. âRefer to the appliance service manual or wiring diagram âfor exact terminal identifications.
Can I replaceâ the switch myselfand what are the â˘basic⤠replacement steps?
Yes, a â¤competent DIYer can replace it, but always disconnect power first. Basic steps: 1) Turn off power at the breaker. 2) Remove âthe control knob(s). â3) âRemove the console⢠or back panel⣠to âaccess the âswitch. 4) Photograph and label all wire connections. âŁ5) âŁUnplug or⢠disconnect the wiring⣠harness/terminal connectors from the old switch. 6) Remove mounting screws and swap in the ânew âswitch.⤠7) Reconnect wiresâ exactly as labeled, âŁreassemble, restore powerand test. If â˘you are not âagreeable withâ electrical work, hire a⤠qualified appliance technician.
How shouldâ the switch terminals be wired and labeled?
Terminal labeling varies by design, but â¤typically⤠you’ll âsee a line (L) or⣠common terminal, one âor more âoutput/load terminals toâ the surface elementand sometimes a terminal for anâ indicator⣠light or sensor. As label conventions âare not universal, always photograph and/or markâ each wire⤠before removal andâ consult the wiring diagram on the appliance or in the serviceâ manual. âŁIncorrect wiring can damage the â˘new switch or create a safetyâ hazard.
Is there a way⤠to tell if the problem â˘is âthe switch or âŁthe surface âŁelement?
Yes. With the power off,â you âcan⤠test âŁthe element for continuityâ directly atâ its terminals â˘- a good element will show â˘continuity (a âŁspecific resistanceâ depending â˘on element type). If the element is good âŁbut the âburner doesn’t âheat when the switch⢠is turned on, the switch â¤or its wiring is highly likely at fault. Conversely, if the element is âopen (infinite resistance), replaceâ the element. Always make sure the wiring â˘between switch and element is intact â¤and connectors are secure.
Where can I⢠buy part 318293827 and how much does it â¤typically cost?
The part is âŁsold by Frigidaire/electrolux authorized parts dealers, appliance⤠partsâ storesand âŁreputable online marketplaces.Prices vary by seller and region â˘but typically range from about $25⣠to â$80. Buy from trustedâ suppliers âand verify the part number and model compatibility⢠to avoid âreturns.
are âthere any safety warnings âor additional checks to⤠perform â¤after⢠replacing⤠the â¤switch?
Yes.After replacement,â double-check⣠thatâ all âŁwires â˘are properly connected andâ insulated,â knobs are reinstalled correctlyand â˘all panels âare secured.Restore power and test each setting while observing â˘for⢠correct operation, unusual noises,â sparks,⢠or burning smells. If you notice any abnormal behavior, disconnect power instantly and âconsult a technician. â¤Always â¤follow local electrical codesâ and use a qualified electrician⤠for hardwired or complex repairs if unsure.
