Function and Role of the Surface Element switch in Frigidaire Electric Ovens
The 318293827 Frigidaire âŁOven Surface Element⤠Switch â is a user-facing control⢠that regulates mains power to aâ cooktop surface element by mechanically switching and cycling theâ supply to achieve different heat settings. In practical terms it functions as an on/off/cycling contact assembly: turning the knob moves internal contacts through⢠detents â¤or âa â¤resistive ânetwork so the element âreceives a proportion of full lineâ voltage for âlow, mediumor high heat.â Technicians encounter âŁthisâ part when symptoms include no heat, only full- or no-power output, intermittent operationor visible burn marks at the terminal block; in those cases the switch often showsâ contact âwear, pittingor a failed actuator that prevents normal cycling.
The switch mustâ match the oven’s mounting, âshaft length andâ terminal configuration to be a drop-in replacement, so verifying the 318293827 part number against model-specific parts â˘lists prevents mismatches in wiring and mechanical fit.Typical service⢠procedures âinclude isolating power, removing the knob and control panel, visually âinspecting terminals for arcingand performing continuity checks while rotating the shaft to confirm switching âthrough positions. â¤Common practical checks âand considerations for diagnosis and replacement are listed below.
- Symptoms: no heat, stuck âat⢠oneâ setting, arcing/noisy contactor element only works intermittently.
- Compatibility checks: confirm⤠shaft style, mounting hole patternand terminal count before ordering replacement.
- Testing: power off, measure continuity across terminals while rotating control; inspect terminals for burning.
- Installation note: ensure correct âwiring labels and secure fasteners to avoid poor contact or grounding issues.

How⣠the 318293827 Frigidaire Oven Surface Element Switch Operates and Interfaces with the Control âand Heating circuits
The 318293827 Frigidaire Oven Surface Element Switch is⣠a line-voltage, multi-position rotary switch âŁthat routes mains powerâ to a surface âheating element and providesâ discrete heat â˘settings⢠or power cycling at each detent. Internally it containsâ heavy-duty contacts sized for cooktop current, multiple contact paths or a cycling mechanism to achieve lower heat settingsandâ one⤠or moreâ external âterminals for the element, âincoming supply, âŁand often âŁan âindicator lamp.⢠Technicians⣠will notice that the switchâ does not regulate temperature by low-voltage controlâ signaling; instead it either selects different contact circuits or intermittently connects the element to the supply âto obtain reduced power output.
- Terminals: supply â(line),load â¤(element),and sometimes an indicator or pilot lamp terminal
- Behavior: âdirect line switching,detented positions,and duty-cycle control at lower settings
- Common âfailure⤠symptoms:⢠no power to â˘element,stuck-on heat,intermittent operation,or visible contact damage
In a range wiring harness the switch interfaces directly between the incoming circuit breaker feed and the heating element: one supply conductor is connected to âthe switch âcommon,and⢠the switched output goes âŁto the element terminal; the⣠element completes the circuit back to neutral or the second hot leg depending on the appliance design.Some â¤frigidaire ranges also route a lamp or control-signal lead â˘through a terminal on the switch so the control panel can receive a âsimple on/off indicator. For compatibility and safe replacement, match the 318293827 Frigidaire Oven Surface Element Switch by terminal layout, â˘physical mounting, âŁandâ current/voltage rating; during⢠troubleshooting confirm expected voltage at the supply â¤terminal with theâ unit energized and verify continuity â¤across⣠the selected output terminal with the element disconnected toâ avoid false â¤readings.

Common âFailure Symptoms and Diagnostic Indicators of Surface Element Switch Malfunctions
The 318293827 Frigidaire Oven Surface element Switch is a userâoperated selector that routes mainsâ voltage toâ the cooktop element through stepped contacts or aâ variable resistor assembly.In normal âoperation the switch⤠provides discrete power taps (or continuous variation on infiniteâtype switches) â¤and must match the oven’s terminal layout, voltage ratingand mounting footprint to be compatible. Technically, the part âis a lineâvoltage switching device: failures are â¤usually contactârelatedâ (open circuit, pittingor welded contacts), mechanical (worn âdetents or broken shaft)or thermal (degraded insulation or melted⢠terminals) rather than failures of the element itself. Practically, a failed âswitch can present the same symptoms as âa bad element, so model and terminal compatibility should⤠beâ verified before replacement to ensure proper electrical ratings and⢠fit.
Common diagnostic indicators include complete loss of â˘heat on one burner,â heat only on high settings,⣠intermittent operation, persistent onâstate, visible arcing,⤠discoloration around terminalsand unusual odors. Troubleshooting typically begins with a visual inspection for⣠burn marks and loose connections, followed by continuity and resistance checks âwith power removed: a â˘closed⤠contact â¤should read near 0 Ί between the common and the selected tap, while an open contact should show infinite resistance. Under load âtesting âwith a meter or clamp ammeter (performed only by qualifiedâ personnel) confirms whether⤠voltage is actually delivered⣠to the element; inconsistent â˘voltage under different switch positions points toâ internal â¤contact failure. For field clarity, the list belowâ summarizes the most common symptoms to watch for.
- No heat on one burner while others operate normally
- Heats only on the highest setting or skips lower taps
- Intermittent heating orâ cycling unrelated to the control knob position
- Visible arcing, meltingor burn marks at switch terminals
- Burning smell or signs of overheating⢠near the switch assembly
| Item | Description |
|---|---|
| Continuity test | With power⣠removed, expect near 0 Ί âbetween common⤠and selected tap; infinite Ί⤠when unselected. |
| Voltage under load | Live voltage âat the switch output should match â¤supplyâ (e.g., ~240 V â¤splitâline)â for selected high âtap; lower tapsâ show reduced duty â˘via⢠contact arrangement. |
| Visual â˘inspection | Burn marks, pitted contactsor melted⢠insulation â¤indicate contact failure and need for switch replacement. |

Q&A
What âis âŁthe 318293827 frigidaire oven surface⢠element âswitch and what does it do?
The 318293827â is a replacement surface âelement (infinite)â switch used onâ Frigidaire ranges/ovens.It controls the power delivered to a cooktop⣠heating element by switching and varying the dutyâ cycle as you turn the burner control knob. In short, it regulates element heat levels (low to high)â and provides on/off control for that surface burner.
What are the common symptoms that indicate this switch has failed?
Typical symptoms of a bad surface element⤠switch include: a burner that won’t heat at any â¤setting,a burner that is stuck on one âŁpowerâ level (often high),intermittent heating,the knob having no âeffect,or the burner only working when you jiggleâ the knobâ or wiring. Before replacing the switch, check the burner element⣠and the wiring/terminal block, as those parts âcan produce similar symptoms.
How do⤠I test the switch to confirmâ it is indeed faulty?
First disconnect power to⤠the range. Remove the control knobâ and accessâ the âswitch by removing the back control⢠panel.⣠With the switch disconnected from the wiring harness, use a multimeter â˘set to continuity or ohms. rotate the switch â˘through settings and verify the meter readings âchangeâ (showing different resistances or continuity paths) according to the switch’sâ terminals. â¤If the switch shows no continuity â¤where thereâ should be continuity or showsâ erratic/open readings, it’s likely âdefective. Live-voltage tests are possible but should only be âperformed by a qualified technician âwith⤠proper safety precautions.
Can⣠I⤠replace the switchâ myself and what tools are required?
You â¤can replace this switch yourself if you are comfortable with basic appliance ârepair and âelectrical safety. Tools âtypically required: flathead and Phillips screwdrivers or nut drivers, needle-nose pliers, a multimeter (for testing)and possibly a socket set. â¤Always âdisconnect the appliance from âpower at â¤the âbreaker or unplug it before starting. Take photos or label wires before disconnecting soâ you can reconnect â¤them correctly. If you’re unsure, hire a qualified repair technician.
How do I make sure I get the âcorrect replacement part?
Confirm compatibility by matching the frigidaire âmodel number âŁof your â˘range (found onâ the appliance rating plate)â with the part number listing. The âOEM part number (318293827) should match the part listing. Also compare physical mountingâ style, number and arrangement of terminals, âand knob shaft type. buying from an authorized parts⢠dealer or directly from Frigidaire⤠helps ensure you get the correct⤠OEM switch.
Are there wiring or mountingâ details I should know about before installing?
Yes. note the⣠terminal layout and wire colors before removal âŁ-â take â¤photos or label each wire. Many switches have spade terminals labeled for â˘element,line,and neutral/ground; make sure each wire returns to â¤the same terminal on the new â¤switch. Mounting may use a retaining nut or screws; install the switch so the shaft and knob align correctly. â¤Ensure all spade connectors â¤are fully seated and secure to â˘avoid âarcing.
What otherâ components should I check if â˘replacing âthe âŁswitch doesn’t âfixâ the problem?
If replacing the switch doesn’t fix the âburner issue,check the cooktop element âitself for continuity (an⣠open element means it’s bad),theâ terminal block where theâ element wiresâ connect for corrosion or loose connections,and the range’s wiring harness for damaged wires. On some models, the clock/timer or âelectronic⣠control (if it controls element power) could also be at fault. â¤Systematic testing âwith a multimeter will help isolate the failing component.
