316219004 Frigidaire Stove Oven Range Cooktop Wiring harness with Ignitor Switch is an electrical harness assembly that integrates wiring, terminalsand a user-actuated ignitor switch used on gas cooktops and ranges. As a discrete electromechanical component, it provides the routed conductors and connector interfaces required to link the control knobs or switch mechanism to the appliance’s ignition circuitry and related electrical subsystems.
Inside the appliance, the harness and ignitor switch serve as the electrical pathway and switching element that enables the ignition sequence: when the cooktop control is actuated the switch closes the circuit to the spark generator or ignitor module, allowing high-voltage pulses to reach the spark electrodes while also interfacing with the control board, gas valve solenoids and chassis ground. The harness is typically routed beneath the control panel or cooktop surface, uses heat- and abrasion-resistant insulation and keyed connectors to maintain correct signal routingand plays a direct role in timing, safety interlocks and reliable spark delivery for burner ignition.
In this article readers will find a technical overview of the component’s function and physical characteristics, guidance on model compatibility and connector types, common failure symptoms (such as no-spark, continuous sparking, intermittent ignition, visible damage or arcing), practical troubleshooting checks and test points a technician can useand replacement considerations such as verifying part numbers, routing and heat protection, connector matingand safety precautions to follow during service.

Function and Role of the Cooktop Wiring Harness and Ignitor Switch in Frigidaire Range Systems
The 316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch provides the electrical pathway between front-panel controls, the spark/ignition moduleand each burner electrode. The harness combines multiple insulated conductors, mating connector housings and a dedicated ignitor switch into a single assembly so the control knobs can reliably command spark generation without adding field splices. In practical installations this assembly must match the original connector pinout and wire routing for the range model, use heat-resistant insulation near high-temperature areasand include strain reliefs to avoid terminal stress during service or operation.
Functionally, the ignitor switch within the harness is a low-voltage switching element that closes to signal the ignition module when a burner is selected; the module then produces the high-voltage pulses that jump the electrode gap. Typical failure modes are chafed insulation, corroded or overheated terminals, broken conductors at connector crimps, or a stuck switch that causes no spark or continuous sparking. Technicians troubleshoot by visual inspection for heat damage, checking connector integrityand using a multimeter to verify continuity and proper switching behavior; replacing the entire 316219004 assembly preserves correct routing and connector mating, reducing the risk of miswiring during repair.
- Primary functions: route power and control signals, provide a switching interface to the ignition module, and maintain OEM connector pinouts.
- Common symptoms of failure: intermittent or absent spark,continuous sparking,visible burn marks at terminals,or loss of control response from knob actuation.
- Troubleshooting steps: inspect for physical damage, verify continuity across the switch, check for corrosion on spade/Molex terminalsand compare pinouts to service diagrams before replacement.

How the 316219004 Frigidaire Stove oven Range Cooktop Wiring Harness with Ignitor switch Integrates with Power, Ignitionand Control Circuits
The 316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch functions as the electrical backbone that ties the user controls, ignition electrode, gas valve (or ignitor assembly)and the main control electronics together. Its bundled conductors provide both the switched power legs and the signal paths required for ignition: one or more hot legs and neutral/return conductors carry mains voltage to the ignitor and valve circuits, while smaller gauge, color-coded leads route low-voltage control signals to the range’s electronic control module or mechanical switches. The integrated ignitor switch in the harness completes the ignition circuit when a burner control is actuated, routing power to the spark generator or hot surface ignitor and concurrently providing feedback or safety interlock connections that prevent valve operation unless ignition conditions are met. Compatibility depends on matching connector types, pin assignments, wire gaugesand insulation ratings to the appliance model and control architecture; mismatched pinouts or undersized conductors can cause intermittent operation or failure to light even if connectors physically fit.
Electrically, the harness establishes distinct functional zones: a mains power feed and switched leg for heating/ignition, a high-voltage spark path or hot-surface ignitor ledand low-voltage control/sensor returns to the control board. Typical failure modes encountered in service include broken or brittle conductors at high-stress points,corroded spade terminals that increase contact resistance,and misrouted wires causing chafing.Technicians use continuity checks and visual inspection of connector crimps to isolate harness faults; replacement harnesses must reproduce the original routing and terminal types to preserve expected behavior of thermal limits, flame sensorsand interlock switches. Practical interoperability features are listed below for speedy reference.
- Power feed: mains hot/neutral conductors supplying ignitor and valve circuits.
- Ignition path: dedicated wire(s) to spark module or hot-surface ignitor electrode.
- Control signals: low-voltage leads to/from the electronic control board or mechanical switches.
- safety/interlocks: thermostat/limit and flame-sensing returns integrated into the harness.
- Connector style: color-coded, keyed spade or Molex-style connectors to ensure correct mating.

Common Failure Symptoms, Electrical Fault Indicators, and Diagnostic Signals for the Wiring Harness/Ignitor Switch Assembly
The 316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch provides the electrical routing and switching required for reliable spark or glow ignition in compatible Frigidaire ranges. The assembly includes insulated conductors, connector terminals sized to match the range control and ignitorand a switch element that directs power when the control calls for ignition. Proper compatibility depends on matching pinouts, wire gauge, terminal styleand insulation temperature rating to the appliance - incorrect connectors or undersized wiring can introduce voltage drop, heat at crimp jointsor intermittent contact that mimics more complex control-board failures.
Common failure symptoms are practical diagnostic cues: absence of ignition, continuous sparking without lighting, intermittent operation when the harness is flexed, visible arcing or melted insulation at connectorsand the presence of gas odor with no ignition. effective troubleshooting uses basic electrical checks: verify continuity through each conductor and the switch assembly,confirm the expected voltage presence at the harness connector when the range calls for ignition,inspect for localized heating or charring at terminals,and compare measurements at both ends of the harness under load. For example, if the control supplies voltage at the connector but the ignitor does not glow, the harness conductor or the ignitor/switch contacts are likely open or high-resistance; if there is voltage loss between connector points or visible arcing, replace the harness and repair any damaged terminals to restore safe, repeatable ignition.
- No ignition despite control calling for heat (open conductor or failed ignitor/switch)
- Continuous sparking without lighting (stuck switch contact or grounding fault)
- Intermittent ignition that changes with vibration or flexing (broken strand or poor crimp)
- Burnt/melted insulation, discolorationor arcing at connectors (overheating or short)
- Voltage present at connector but ignitor does not draw current (failed ignitor element or high-resistance connection)
| Item | Description |
|---|---|
| Open conductor | Infinite resistance on continuity test; ignition fails even when control supplies voltage |
| High-resistance/crimp failure | Elevated voltage drop under load, intermittent operation, localized heating at terminal |
| Short to ground | Blown fuses, tripped safety devices, continuous sparking or no control signal |
Replacement considerations, Model compatibilityand Stepwise Installation Procedures for the Wiring Harness and Ignitor Switch
The 316219004 Frigidaire Stove Oven Range Cooktop wiring Harness with Ignitor Switch is a combined electrical assembly that routes line and control signals from the range control to the surface ignitor and the manual or electronic ignitor switch. The harness contains high‑temperature rated conductors, molded connectorsand insulation sleeves designed to resist heat and mechanical abrasion; the ignitor switch provides the switching path that permits high current to reach the ignitor element while keeping low-voltage control circuitry isolated. Common failure modes are open or shorted conductors,intermittent connector contact,and heat-degraded insulation,so technicians typically verify continuity,inspect connector pin engagement,and observe ignitor current draw during an ignition cycle to confirm correct behavior.
Replacement and installation require matching electrical and mechanical characteristics: verify pinout and terminal type, wire color mapping, harness length, and mounting tab locations against the appliance model or service manual. Follow safe service practice: disconnect power and gas supply, document existing wire routing, replace the harness with equivalent heat-resistant terminals and secure strain reliefs, then perform continuity and operational tests before final reassembly. Practical considerations include reusing factory brackets when intact, avoiding wire routing across hot chassis edgesand confirming the ignitor switch rating is compatible with the ignitor’s inrush current to prevent premature failures.
- Step 1: Disconnect power and gas; remove access panel to expose the harness.
- Step 2: Photograph and label connectors; note pin positions and wire colors.
- Step 3: Disconnect connectors and remove mounting hardware; extract old harness carefully from high‑heat paths.
- Step 4: Install new harness, route wires using the original clips, secure mounting tabsand ensure strain relief at entry points.
- Step 5: Verify continuity and switch operation, apply power briefly to confirm proper ignition behavior, then reassemble and test multiple cycles.

Q&A
What is the 316219004 Frigidaire stove/oven/range cooktop wiring harness with ignitor switch and what does it do?
The 316219004 is an OEM wiring harness assembly used on certain Frigidaire ranges. It includes the electrical connectors and the ignitor (spark) switch that routes power from the control knob to the surface burner spark module or igniter. In short, it connects and controls the spark circuit for one or more surface burners and carries the low-voltage signals between the knob/switch and the ignition module.
What symptoms indicate this wiring harness or ignitor switch is bad?
Common signs of failure include one or more surface burners failing to spark or sparking intermittently, visible burn marks or melted insulation on the harness, a knob that doesn’t click or actuate the spark when pressed/turnedor a burner that ignites only when the harness is manipulated. If the electronic ignition module works on other burners but not the one tied to this harness, the harness or its switch is highly likely at fault.
how do I verify that part 316219004 is compatible with my Frigidaire range?
Check the range’s model number (typically on a tag behind the oven door, on the frameor on the back of the appliance) and search that model number with the part number on the manufacturer’s parts list or a reputable parts website. You can also compare the connector shapes and number of wires of the existing harness to pictures/specs of 316219004. When in doubt, confirm compatibility with Frigidaire support or an authorized parts distributor using your model number.
Can I test the wiring harness and ignitor switch with a multimeter? If so, how?
Yes.First disconnect power to the range. For the switch portion, set the multimeter to continuity or lowest ohms range. With the harness unplugged,actuate the switch (turn/press the knob as it would operate) and check for continuity between the switch’s two terminals-continuity shoudl appear when the switch is in the “spark” position. also test each wire for continuity back to its connector pins and inspect for shorts to ground (measure resistance between each wire and chassis; should be very high/infinite). Visually inspect connectors and wiring for corrosion or melted insulation. If continuity is absent when the switch is actuated, the switch/harness is faulty.
What are the basic steps to replace this wiring harness and ignitor switch?
Turn off power at the breaker and shut off the gas supply. Remove control knobs and any trim or back panel needed to access the harness. Take clear photos of the wiring and connector positions before disconnecting. unplug the harness connectors from the igniter module and any other mating plugsand remove any clips or fasteners holding the harness. Install the new 316219004 harness by routing it the same way, snapping on clips and connecting each plug to its matching connector, then reassemble. Restore gas and power and test operation. If you’re not agreeable working with gas and electrical systems, hire a qualified appliance technician.
Do I need to recalibrate or do anything else after replacing the harness?
No electronic recalibration is required.After replacement,simply restore power and gas,verify that the burner sparks and lights correctly,and confirm that all knobs function as expected. if ignition is inconsistent after replacement, recheck connector seating and groundingand confirm the ignition module and burner electrodes are working.
What common installation mistakes should I avoid?
Don’t attempt repairs with power or gas on. Avoid routing the new harness where it can touch hot components or sharp edges; secure it with the original clips so it can’t chafe. Do not mix up similar-looking connectors-force-fitting a connector can damage pins. Don’t ignore signs of damage to the spark electrode or ignition module; replacing the harness won’t fix a faulty igniter. document original wiring (photos) before disconnecting so you can reconnect correctly.
Can I use an aftermarket harness instead of part 316219004and are there differences I should be aware of?
Aftermarket harnesses are often available and can be less expensive, but quality varies. Choose a harness made for your exact model or listed as compatible and check that connector types,wire gauges,lengths,and the switch function match the OEM part. OEM parts like 316219004 guarantee fit and original specifications, which reduces the chance of fitment or reliability issues.If unsure, buying the OEM part or consulting a qualified parts supplier is recommended.
