316219004 Frigidaire⤠Stove oven Range Cooktopâ Wiring Harness with Ignitor⤠switch is a factory-design wiring assembly that combines insulated conductors, connectorsand an integrated ignitor switch used in gas⢠cooking appliances to âŁcomplete and control the ignition âŁcircuit for burners. As a discrete electrical⢠assembly, the harness âŁorganizes⤠andâ protects multiple âsignal and power wires while the ignitor switch providesâ the user- or control-driven contact closure necessary â˘to initiate the âappliance’s spark or glow â¤ignition sequence.
Inside a ârange or cooktop the harness and⣠ignitor switch form the electrical âbridge betweenâ the âuser controls â¤orâ control board, the spark/ignition moduleand the gas valves or igniters. The component⤠routesâ low-voltage control signals and âprovides the⤠switching interface that tells the ignition module to generate spark (or âtoâ energizeâ an igniter), while its connectors and insulationâ must withstand⢠elevated temperatures,â vibrationand exposure to grease.In service the harness âŁtherefore interacts directly with âŁthe control console, ignition module, burner ignitersand âsafety interlocks⤠(and indirectly âwith flame sensing andâ gas valve operation),â making correct pinout, connector âtypeand routing critical to safe, âreliable ignitionâ performance.
This article will describe the harness’s functional role and typical⤠wiring âlayout, outline compatibility considerations (model fit, connector and terminal typesand wire color⤠codes), identify âcommon â˘failure symptoms (no ignition, intermittent sparks, âvisible damage, arcingor loss of continuity)and present practical troubleshooting checks and⢠replacement considerations. Readers can expect âguidanceâ on appropriateâ diagnosticâ measurementsâ (visual inspection, continuity/voltage verification), how to confirm correct part selection and connectorâ matingand factors to observe âwhen replacing the â¤assembly-including heatâ protection, secure routing,⤠and adherence to safety â˘precautions such â˘as disconnecting electrical⢠power and â¤gas supply before anyâ service.

Functional role and âelectricalâ responsibilities of the wiring harness and ignitor switch
The 316219004 â¤Frigidaire Stove â˘Oven â¤Range Cooktop Wiring Harness with Ignitor Switch serves as the âintegrated electrical interface between theâ cooktop controls,the ignition system,and individual burner elements. âThis assembly contains color-coded leads, mating â˘connectors, mounting points andâ the ignitor switch itself so that the control â¤board and ignition transformer (or hot-surface ignitor)â can be connected without âsplicing. In practice theâ harness organizesâ line⢠andâ control circuits and providesâ strain relief and insulation⤠to protect âcontacts from heat and âvibration common in range environments, ensuring⢠consistent electrical connection⣠and correct⣠phasing â˘of signals to each â˘burner.
Electrically, theâ harness routes householdâ line and control voltages â¤to the âŁignitor switchâ and â˘onward to the ignition device while also providing⢠return and grounding conductors. Whenâ a burnerâ isâ commanded,⢠the control sends voltage through the harness to the ignitor switch; the⣠switch thenâ routes âthat signal so the ignition transformerâ or ignitor receives â¤power and the â¤gas valve â˘or⢠control relay is enabled in the correct sequence. Technicians commonly verify function by checking connector⣠continuity, confirming â˘control voltage at⤠the switch (typically line-level controlâ voltages)and inspecting for brittle insulation or corrosion thatâ causes intermittent â˘opens âŁunder heat. Replacing a defective harness with â¤the⤠specified â˘316219004 unit restoresâ factory connector⢠configuration and wiring color code, avoiding miswiring âŁand⣠simplifying diagnostics.
- Power distributionâ to âignition device and control circuits
- Signal routing and sequencing (control to ignitor and âgas/valve⢠relay)
- Mechanical protection: heat-rated insulation, strain reliefsand locking connectors
- Serviceability: âplug-and-play replacement reduces wiring errors
| Item | Description |
|---|---|
| Typical control voltage | Line-level control voltage (household AC) routed to switch and ignitor circuit |

How the 316219004â Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor⢠Switch interfaces with ignition, â˘gas âvalvesand control circuits
The 316219004 Frigidaire Stove â˘Oven Rangeâ Cooktop Wiring Harness with Ignitor Switch â¤functions as âŁtheâ electrical junction that ties the user-facingâ ignitor switch, âŁthe âspark generator, the burner âelectrodes, âand the âgas valve coils into a coordinated ignition system. Internally the harness âŁseparates âand routes low-voltage control âpower and switching signals (from the control board or switch) and the⢠high-voltage pulse⢠that fires theâ ignitor electrode; shielding and insulated leads in the harness prevent arcing âand cross-talk betweenâ thoseâ circuits.⤠Technically,the harness contains â¤discrete⣠conductors and âŁkeyed connectors that â¤mustâ match the stove’s pinout and voltage âŁratings,plus strain reliefs and heat-resistant sleeving at the burner end; when replacing this part,confirm connector shapes⣠and continuity of the ignition lead âand valve coil âwires rather than relyingâ solely⣠on model numbers to ensure⢠compatibility with a given Frigidaire cooktopâ or range control âscheme.
In operation the ignitor switch closes a control circuit that tells the spark⤠module to generate a high-voltage pulse while together enabling the gas valveâ coils; the harnessâ carries the command and the return paths so the timing of spark and gas flow align.Fault behavior â˘is â˘frequently diagnostic:â intermittent sparking or no spark with a steady gas valve click often points to a â¤broken âhigh-voltage lead or corrosion at a⣠connector,whereasâ a âcontinuously⣠energizedâ ignitor or â¤failureâ of a valve to open suggests a shortedâ switch âor an â˘open coil circuit accessible through the harness wiring. Technicians commonly test the harness for âcontinuity of âeach conductor,â insulationâ breakdown on the high-voltage leadand correctâ resistance âof valve coil wires against the range schematic âbefore replacing âthe part to avoid misdiagnosingâ control board faults.
- Typical harness features: separate high-voltage ignition lead, low-voltage control conductors,â keyed â˘connectors, âŁheat-sleeving at burner ends.
- Common symptoms indicating harness issues: no spark, erratic spark, gas valve not actuating, connector⢠overheating â˘or melting.
- Practical⣠checks: connector pin mapping, continuity âand resistance measurements, visual insulation and connector integrity â¤inspection.
| Item | Description |
|---|---|
| Ignitor âŁcircuit | High-voltage pulse path from spark module to electrode; requires insulation and proper routing to prevent arcing. |
| Gas valve circuit | Low-voltage â¤power andâ return â¤for⢠valve coils;â harness provides fused/ switched âŁfeed and common return to control board. |
| Control interface | Connectors and âŁsignal wires between âignitor switch/control â˘board and âŁspark â˘module for timing and safety interlocks. |
Common failure symptoms, measurableâ electrical faultsand⢠diagnostic indicators
Theâ 316219004⣠Frigidaire Stove Oven Range Cooktop⣠Wiring â˘Harness with Ignitor Switch carries mains power â˘and⢠switching signals between the cooktop controls, the spark module â(or door interlocks), âand each burner ignitor. In ânormal operation the harness â¤provides low-resistance conductor paths and secure âterminalâ contacts; heat cycles, vibration, âor contamination can create open or high-resistance connections, short-to-ground conditionsor âŁintermittent contact at â˘theâ switch.Typical⣠field symptomsâ tied to wiring-harness faults âinclude âno spark at⣠one or more burners,⢠continuous clicking while a burner is âoff or â¤litor aâ burner that ignites intermittently despite âcorrect gas flow. Visible signs such as melted insulation, â¤discoloration,⣠orâ corroded terminals strongly suggest localized â˘overheating orâ arcing within theâ harness âassembly.
- No âspark on âselected âburner â- measurable open circuit â˘or interrupted âcontinuity between⤠the ignitorâ switch terminal⣠and the ignitor⣠module.
- Continuous sparking -â switch contact stuck â¤closedâ or a short thatâ applies mains to the âignitor continuously.
- Intermittent ignition – high⣠contact resistance or broken wire strandsâ producing intermittent continuity under load or movement.
- Blown â¤fuses or⤠tripped breakers – short-to-ground⢠on theâ harness or switch circuit.
- physical damage – melted âinsulation, burn marksor corrosion at crimped âterminals indicating âhigh-resistance⣠heating âor arcing.
Diagnose the âharness⢠by isolating the circuit and using â¤a multimeter âto check continuity, â˘resistance,⣠and supply voltage. With connectors disconnected, a closed ignitor â¤switch should show⢠very low resistance⤠(near â¤0 Ί) when actuated and an âopen circuit⤠when released; âŁa persistentâ high resistance reading across a short conductor length indicates âcorrosion or a partialâ break. verify that mains âvoltage (typically ~120 VAC inâ North America) is present at the harness âŁinput and â˘that theâ switch â¤routes that voltage to the ignitor output only when actuated; if input voltage â¤is present⣠but noâ output âappears, the switch or internal harness conductor âis the âlikely fault. For intermittent faults,perform a wiggle test while monitoring âcontinuity âor operate the switch repeatedly âto⣠reproduce âŁthe failure; do not attempt⤠to measure âŁhigh-voltage spark output directly with a standard meter. If harness â˘checks pass, expand testing to the spark module and ignitor âelements to locate theâ fault.
| Item | Description |
|---|---|
| Low resistance when closed | Near 0 Ί across switch contacts – indicates good conductor and contact closure |
| Open circuit | Infiniteâ resistance -⣠wire break or open switch contact |
| High resistance | Higher than a few âohms for⣠short leads – suggests corrosion, loose crimpor partial break |
| Voltage present at input only | Mains âŁat harness feed but no switched output – faultyâ switch⢠or internal open conductor |
Model compatibility, replacement âconsiderations, step-by-step installation and post-install troubleshooting
The 316219004 Frigidaire Stove Oven Range⤠Cooktop Wiring Harness âwithâ Ignitor âSwitch serves as the low-voltage and⢠control interconnect between burner⤠ignitors, user â¤controlsand the range’s safety circuits. compatibility hinges âon matching connector pinouts, âmounting points, âharness length, â¤and â˘the switch’s âelectrical⢠rating – not just the part number printed on the old component. when evaluating⢠a replacement,compare⤠the physical connectors,wire colors and grouping,terminal⢠types (spade,molex,etc.),â heat-resistant sleevingand any strain-relief clips; a harness that fits the cabinet but has differentâ terminalsâ or lacks⣠heat protection can âŁcreate intermittent faults or⢠premature insulation failure. Service documentation or photographs of the original âassembly⤠are practical references for âŁensuring the replacement harness matches the⢠oven’s routing and clearance⣠requirements near⤠heat sources and control assemblies.
Installation requires methodical disassembly, secure connectionsand⢠post-install verification⤠to avoid diagnostic confusion. Follow a⢠controlled removal⤠and install sequence,preserve⤠or transfer mounting clips and insulating components,and perform continuity âand functional tests before âreassembling panels. If burners â¤fail to ignite or ignition is intermittent afterâ installation, âŁcheck for âŁpoor terminal contact, â¤chafed â˘wires, incorrect routing ânext to heating elements, âor a failing ignitor⣠element which âwill present as open or⤠high resistance. If measurements at the switch show correct continuity âŁbut no spark at the⢠burner, focus⤠troubleshooting on âthe ignitor and âŁhigh-voltageâ paths; if there is no continuity through âtheâ switch, âŁreplace â˘the harness or switch assembly and recheck grounding and âŁchassis connections.
- Power off⢠and unplug the appliance and tag âŁtheâ breaker; document connector locations with photos.
- Remove panels to âaccess the harness; â˘note and label each connector and⢠wire bundle.
- Disconnect the â¤old harness, transfer heat shields â¤and mounting hardware, âand install the new âharness⢠matching pinouts and â¤routing.
- Secure strain reliefs and keep wiring clear of burners âand vent openings; reassemble panels⢠enough to test.
- Test continuity of⢠ignitor and switch, restore power⢠briefly to verify⤠ignition, âthen fully⤠reassemble if tests pass.

Q&A
What is the 316219004 Frigidaire⢠wiring harness with ignitorâ switch and what does it replace?
The 316219004 is an OEM replacement⤠wiringâ harness assembly for certain Frigidaireâ (and related brand) gas ranges. It typically contains⢠the â¤electrical leads and⣠the ignitor/ignition switch that send voltage to the spark igniters and/or gas âvalve when⤠a burner control is â¤actuated. It replaces the original harness and switch assembly that âhas failed, corroded, melted,â or hadâ connector damage.â Always â¤verify the part number against your oven/range model number before ordering.
How do I know⢠if the harnessâ orâ ignitor â¤switch is⤠the cause of my range not sparking?
Common signs âof a bad âharness/switch⤠include no spark when turning â¤the burner knob,⣠intermittent sparking, visible âburned/melted wires or connectorsor aâ persistent âŁopen circuit⢠onâ the switch. Use a multimeter: with power off, check continuity across the switch when âit⢠is â˘engaged; withâ power on and safetyâ precautions, check âfor the expected line voltage (typically ~120 VAC in the US) reaching the igniter circuit when the â¤knob is turned. âŁIf the switch shows no continuity when activated or no voltage is present at⤠the igniter connector despite⣠a good igniter, âthe harness/switch â˘is âŁa likely culprit.
Is the 316219004 harness⢠plug-and-play â¤or will I need to rewire anything?
In most cases theâ OEM 316219004 harnessâ is plug-and-play: it usesâ the factory-style connectors and mounting â˘pointsâ designed for⤠compatible models. However, you âŁshould still label or photograph wire positions before removal to ensure correct reconnection.Verify that connector types and âŁlead lengths â¤match yourâ appliance; âŁsome models had small revisions and may require minor routing adjustments or different mounting clips.
Does this part⣠include the âspark â˘igniter electrode or the sparkâ module/ignition module?
typically the â316219004 assembly includes âŁthe wiring⣠harness and the âswitch, but not the individual spark electrodes (the ceramic/spark rods at the burners) nor the separate ignition control module if âyour model uses⤠one. Product listings vary, soâ confirm the included components in the seller’s description. If â¤your⢠electrode or ignition module is faulty, replacing the harnessâ alone may â˘not fix âŁthe âproblem.
What safetyâ steps and tools are required to replace the harness and⤠ignitor switch?
Safety first: disconnect power to the âappliance at âŁthe breaker and shut off the gas supply⣠if you will be working near â¤gas components.⣠Basic tools: screwdrivers, nut drivers,â needle-nose⢠pliers, electrical tape or⣠heat-shrinkand a multimeter⢠for testing. Work in a well-lit area, keep track ofâ fasteners and grounding connectionsand avoid forcing âconnectors. If you are not comfortable working â˘with live electrical systems or gas appliances, hire a qualifiedâ technician.
How do I install and test the new 316219004 harness after âreplacement?
Installationâ steps in âbrief: 1)⤠Disconnectâ power and âŁgas.⢠2) Remove the âaccess panels/controls to reach the old harness. â3) Photograph and⢠label connections, thenâ disconnect connectors and remove the old harnessâ and switch.â 4) Mount âthe⢠new âharness/switch and âŁconnect the âfactory connectors according to labels/photos. 5) Secure wires away from sharp edges and⤠heat sources. â6) Restore power (andâ gas) â¤and test operation: turn a burner knob and verify the switch supplies voltage to the igniterâ and you get reliable sparking. Use a⢠multimeter to confirm âvoltage if âŁthere’s no spark. Reassemble panels when testing is⣠successful.
How âcan I test the âŁignitor switch without removing the wholeâ cooktop?
You â¤can often⣠access the switch from â˘the âback â¤panel or⤠control âpanel opening. With power â˘off, remove the control â˘panel⣠cover to access the switch terminals. Use a multimeter for continuity testing:â verify continuity across the âswitch only âŁwhen the control is in the âigniteâ position (and no continuity⢠when â¤off). For a live âŁtest (only if experienced âand cautious), with⢠the burner âcontrol turned toâ ignite, measure for the expected AC voltage âat the switch output terminal. If unsure, â˘call a technician-live voltageâ and gas are hazardous.
What are common causes of⣠failure for this harness and how can Iâ prevent future problems?
Failure modes include heat damage âŁfrom⢠nearby âburners, chafing and broken⣠insulation fromâ improper routing, corrosion from moisture or â˘food spillsand arcing from loose â˘connections. Preventive measures:â route and secure the harness away âfrom hot surfaces, replace any damaged insulation or⤠clips, keep âthe cooktop area clean and dry,â ensure⤠connectors are⣠fully seated, â¤and check periodically âfor discoloration or brittleness. Using OEM⣠parts (like 316219004) helps ensure correct â¤fit⢠and temperature-rated wiring.
