Functionâ and Role âŁof the Surface âŁElement⣠Switch in Frigidaire Electric Ovens
The 318293827â Frigidaire Oven Surface Element Switch is an electromechanical control âthat routes⢠and âmodulates the electrical âsupply to a surface heating element. functionally it selects which element âŁreceives power and variesâ the delivered energy by opening and closing internalâ contacts⢠inâ aâ stepped or⢠continuously varying duty â¤cycle according to the knob âsetting. âŁThe switch is mounted behind⢠theâ range controlâ panel⤠and⣠uses multiple spade terminals âfor line, load and, in some â˘designs, an⤠indicator lamp or âŁthermostat input;â correct âŁreplacement requires âmatching the terminal â¤layout, âmounting bracketand current/voltage ratings â˘so⤠the element â˘and any pilot light operate as intended.
Technicians diagnose switch problems⤠by observing electrical behavior and mechanical condition: a failed â˘switch⣠may produce no heat onâ aâ given burner, a single fixed heat level regardless of knob position, â˘intermittent heatingor visible arcing or⤠burned terminals. Troubleshooting â¤typicallyâ involves visual inspection, measuring continuity across âthe appropriate terminals while rotating the controland confirming the switch’s⢠amperage rating againstâ the element âload.⤠Practical examples: if the front-right element never â¤energizes â¤while theâ rear-right works, the switch for the âfront element is a likely âfault; ifâ the indicator lamp does not â¤light â˘with theâ element on, the lamp terminal or its connection â¤on⣠the switch shoudl be checked.
- Common symptoms:â no â¤heat on one element, stuck⢠high/low heat, intermittent âoperation, burning smell orâ visible arcing.
- Key checks: terminal â˘layout, continuity⢠across positions, physical signs of overheatingand amperage/voltage rating⤠match.
- Replacement guidance:⤠match spade terminal configuration and mechanical mounting for âplug-and-play installation.

How the 318293827 Frigidaire â˘Oven Surface Element Switch Operates Within âthe Control âŁCircuit and Element Assembly
The 318293827 âŁFrigidaire⣠Oven surface Element⢠Switch â¤is a multi-positionâ control device that routes mains voltage to a cooktopâ element according to⢠the user-selected heat⢠level. Mechanically,â the switch makes âand breaks the hot conductor(s) through a series of detented contacts or âa resistive âtrack, providingâ discrete or stepped power⢠settings⢠toâ the element.⤠In normal â¤operation âthe switch transfers full⤠line voltage to the selected terminal(s)â and âreturns âto an open state when set to off;⢠failures typically â˘manifest as⢠open⤠circuits (no heat) or welded/shorted â¤contacts (element stays energized). Technicians will recognize âthe switch by its spade-type terminals and mounting flangeand should⢠treat âit as the primary control point when diagnosing intermittent or stuck burner conditions.
Compatibility and practical service considerations focus⢠on⤠matching terminal layout,mounting orientation,and voltage/current rating rather âthan cosmetic similarity. When replacing the switch, âconfirm that⢠the replacement matches âthe original â¤terminal â˘arrangement âand has⢠an âŁequal or higher current rating (moast ranges useâ nominallyâ 240⣠VAC circuits); incorrect pin spacing or lower current rating canâ cause âŁinstallation âproblems or premature failure. Typical⤠diagnostic stepsâ include measuring continuity at each switch⣠position and verifying that the switch opens when the control â¤is off; a simple â˘multimeter continuity check under load⢠simulation âfrequently âenough distinguishes contact wear⢠fromâ wiring or element faults.
- common symptoms: no âheat, intermittent heating, elementâ stays â˘on.
- Key checks: continuity per position, terminal âspacing, âmounting compatibility.
- Replacement tip: match voltage/current â¤ratingâ and spade terminal layout.

commonâ Failure Symptoms,⣠Electrical⤠Indicatorsand⣠Measurement⢠Criteria for âa Faulty âSurface Element âSwitch
The â¤surface âŁelement switch is a multi-position, thermostatic-type âpower selector that modulates â¤voltage to aâ cooktop â˘element; the replacement part 318293827 frigidaire Oven Surface Element Switch⤠performs that function by routing line voltage âŁthrough selected âinternal contacts or a resistive âtap to achieve âlow, âmediumand high heat outputs. In⤠practice,a faulty⤠switch willâ mimic element failure âbut the element⤠itself âmay test good; technicians should distinguish failures by â¤isolating the element and verifying theâ switch’s behavior at itsâ terminals. Such as, if an element heats only on the highest settingâ but not âon low or medium, the â¤switch may be âfailing to closeâ intermediate contacts even⣠tho the elementâ and â¤wiring are intact.
- No heat at any setting – electrical⣠indicator: open circuit (OL) âŁbetween commonâ and all output terminals.
- Heat âonly at âhigh setting – indicator: continuity â˘only at⤠the âhigh âcontact, open âŁor â˘veryâ high âresistance at low/medium â¤contacts.
- Intermittent heat or âarcing â¤- indicator: fluctuating continuity orâ visible burned/oxidizedâ contacts causing inconsistent resistance readings.
- Short to chassis/ground – indicator:⣠low resistance⢠between âŁone or more switch terminals and the appliance chassis.
| Item | Description |
|---|---|
| Off position | Expect open âcircuit â(OL) between common âand all element âŁoutput terminals. |
| On/high position | Expect measurable continuity between common and the high output terminal; typically a low resistance⤠reading relative âto â˘off. |
| Low/medium positions | Expect continuity⢠that may presentâ higher resistance â˘than the high â¤position âor âa stepped changeâ as â˘the selector moves; absence of⢠continuity indicates aâ failed contact. |
| Ground fault | Resistance between⤠any âoutput/common⤠terminalâ andâ chassis should be OL;⣠low resistance indicates insulation âbreakdown or⢠internal short. |
To verify â˘the switch, disconnect mains â¤power, remove the knobsâ and⢠access theâ switch terminals, thanâ use a multimeter set âto continuity or low-ohms ârange. Confirm that the off position reads open (OL), the high position reads continuityand that âlower settings show either âcontinuity with higher resistance â¤or distinctâ stepped⣠continuity as you â˘rotate the shaft.If readings are âinconsistent, intermittentor show continuity âŁto chassis,â theâ switchâ should be replaced;â also inspect forâ physical signs⣠of overheating orâ melted insulation⣠whichâ often âŁaccompany contact failure.

Q&A
What⤠is â¤the âFrigidaireâ 318293827 oven⣠surface element switchâ and what does it do?
Theâ 318293827 is the âsurface (or â”infinite”) control switch â¤used on Frigidaire electric ranges to regulate âheat to⢠a coil surface element. âIt adjustsâ the element’s power âacross a range of heat âŁsettings byâ switchingâ the line voltage âŁon and offâ to the element to achieve the⣠selected temperature.
What symptoms âindicate the surface element⢠switch is failing?
Common symptoms include a surface burner âthat won’t heat at⤠all,⢠a burner that stays on and â˘won’t turn off, âŁintermittent heating, flickering or âarcing at â˘the controlor heat levels âthat no longer match the selected setting. Visible burning, melted plastic, â˘or a strong⤠electrical⤠smell at the control are also signs⤠of failure.
How can âI safely âtest âthe switch with a multimeter?
Turn off power to the range at the breaker or disconnect the appliance. Remove the control knob and access the rearâ ofâ the control panel to reach the âswitch terminals.With the multimeter â¤set to continuity orâ ohms, check forâ continuity âbetween the common (line) terminal andâ theâ output â¤terminal(s) â˘for different switch⢠positions-continuity âshouldâ appear on positions âŁthat provide heat â˘and disappear in the off position. An âopen (infinite)⣠reading on all positions indicates a bad switch. Also check for continuity⤠from each âŁterminalâ to the metalâ chassis; any continuity âŁto âground suggests⢠a⢠shorted âŁswitch.⢠If âyou areâ not⤠experienced with electrical testing, âhave a qualifiedâ technicianâ perform these checks.
What⤠are the proper steps to âreplaceâ the 318293827⤠switch?
