316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch is a multi-conductor wiring assembly that includes an integrated momentary ignitor switch used on frigidaire gas cooktops and ranges. The assembly typically consists of insulated conductors, fast-disconnect terminals or molded connectors, and a switch actuator that interfaces with the manual burner control. As a discrete electrical subassembly it provides the mechanical and electrical interconnections between the user control, the spark generation system, and the burner ignitors.
Within the appliance the harness and ignitor switch form part of the ignition circuit and interact directly with the spark module (ignition control), the igniter electrodes, and the user-operated control knob or valve mechanism. It routes power and signaling, establishes grounding paths and timing for spark generation, and can include features such as color-coded leads and heat-resistant insulation to withstand the cooktop environment.As it occupies a physical and electrical pathway between the operator interface and the ignition hardware, its condition and correct routing affect both functional ignition and electrical safety.
In the article that follows, readers will find a technical description of the part’s function and construction, guidance on model and connector compatibility considerations, common failure symptoms (such as no spark, continuous sparking, intermittent ignition, or visible damage to wiring/terminals), and a structured approach to diagnostic checks and troubleshooting with appropriate test points. The discussion will also cover replacement considerations – matching terminal types and lead lengths, heat- and oil-resistant insulation, and proper mechanical routing and securing – and also safety precautions to observe before performing any service.

Function and electrical Role of the 316219004 Frigidaire Stove Oven Range Cooktop Wiring harness with Ignitor Switch
the 316219004 Frigidaire Stove oven Range Cooktop Wiring Harness with Ignitor Switch is an integrated wiring assembly that routes mains and control circuits between the range’s terminal block, surface element contacts or spark module, and the user control interfaces. The assembly typically contains color-coded, heat‑resistant conductors, insulated connectors sized to the OEM terminal posts, and a dedicated ignitor switch or switch contacts that close the ignition circuit when a burner control is actuated. Functionally, the harness does not generate ignition energy itself; it provides the switched connection and low‑impedance path required for the ignitor module or element to receive power, and it also distributes element power and sensor/thermostat feedback as required by the specific model wiring diagram.
Technically, failures of this harness manifest as open circuits, shorted conductors to chassis ground, corroded or overheated terminals, and intermittent contact at plug connectors. For troubleshooting, a technician will visually inspect for chafing and heat damage, verify continuity across the switch contacts when the knob is actuated, and measure insulation resistance to chassis if a short is suspected. Compatibility considerations include connector style, wire gauge and length, and the specific routing that prevents heat and abrasion; replacing the assembly with the correct 316219004 unit or an OEM-specified equivalent maintains correct connector fit and preserves the original circuit behavior in gas or electric cooktops.
- Primary roles: power distribution to elements/ignitor, switched control via ignitor contacts, and secure connector/interface to the range harness.
- Common symptoms of failure: no spark or no heat on a surface element, intermittent operation, visible burning or melted insulation, and blown fuses or tripped breakers due to shorts.
- Service actions: visual inspection, continuity testing of the ignitor switch, and replacement with the matched harness for proper fit and electrical ratings.

Internal Wiring Topology, Connector Pinout, and Ignitor Switch Operation inside the Appliance
The 316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch is a multi-conductor assembly that routes control power, ignition pulses, and grounding between the range control board, spark module, burner valves, and the user-accessible switch/knob. internally the harness typically groups low-voltage control conductors and one or more insulated high-voltage leads for the spark electrodes, with ring or spade terminals for valve coils and a common ground conductor. In practical service, technicians will see a molded connector that mates to the appliance wiring block and separate insulated boots for the spark output; this topology prevents HV bleed and makes the harness interchangeable across compatible Frigidaire models that share the same connector and wire color coding.
The ignitor switch in the harness is a switching element that supplies the spark command to the ignition module when the control is set to an ignite position; the switch might potentially be a momentary or maintained contact depending on the user interface design. Common troubleshooting steps include verifying continuity through the switch, checking for the presence of the control feed on the corresponding pin when the switch is actuated, and visually inspecting high-voltage lead insulation for tracking or damage. Typical symptoms tied to harness/switch faults are no spark, intermittent spark, or continuous sparking after shutoff; resolving these requires measuring continuity and control voltage at the connector and confirming the correct pin-to-function mapping shown below.
- Quick checks: continuity across the ignitor switch with knob actuated, continuity from valve coil terminals to common, and insulation integrity of high-voltage spark leads.

| Spark command | signal line from the ignitor switch to the ignition module (insulated from chassis) |
| Valve coil outputs | Individual conductors routed to burner gas valves (typically with ring/spade terminals) |
| Neutral/common | Return conductor common to valves and ignition reference |
| Protective earth | Chassis ground for safety and noise suppression |
Common Failure Symptoms and Diagnostic Tests for Harness and Ignitor Malfunctions
The most common symptoms of harness and ignitor malfunctions are intermittent ignition, weak or no spark, continuous sparking after the control is released, and visible burning or melting at connector terminals. the 316219004 Frigidaire Stove Oven Range cooktop Wiring Harness with ignitor Switch can fail at any of several points: open or high-resistance conductors, corroded or loose spade terminals, cracked insulation that provides a leakage path, or worn switch contacts that no longer make reliable connection under load. In practise,an isolated dead burner usually indicates a local ignitor electrode or connector fault,whereas simultaneous failure of multiple burners points toward a common feed,switch assembly,or the harness bundle that distributes the ignition pulse.
Diagnostic testing combines visual inspection, continuity and resistance checks, and live-voltage verification with proper safety precautions. Use a digital multimeter to verify continuity between the ignitor switch terminals and the harness connector with the control actuated, inspect connectors for heat damage or carbon tracking that can short or leak to chassis, and measure the ignition pulse at the harness while an ignition is commanded (typical spark modules deliver a high-voltage pulse referenced to chassis/ground; the harness must provide a solid ground return and intact feed). Practical troubleshooting sequence: isolate the suspect burner, swap or unplug harness connectors to localize the fault, and confirm whether the ignitor electrode itself shows physical wear or contamination that prevents reliable sparking.
- Visual inspection: check for melted insulation, discolored terminals, soot or carbon tracks near electrodes and connector blocks.
- Continuity/resistance: verify conductor continuity and low resistance at spade terminals and switch contacts; open or very high resistance indicates a break or corrosion.
- Live voltage test: with ignition called,measure for the presence of the ignition pulse at the harness connector and confirm a good chassis ground return.
- Isolation swap: replace or swap the ignitor/harness with a known-good unit when available to confirm fault location without guessing.
| Item | Description |
|---|---|
| Continuity check | Confirm conductor and switch continuity from the control/switch to the ignitor connector; opens identify broken wires or failed switch contacts. |
| Voltage at connector | Measure for ignition pulse while igniter is commanded; absence of pulse suggests harness, switch, or upstream module failure. |
| Visual/thermal signs | Melted insulation, discolored terminals, and soot indicate overheating or arcing and typically pinpoint the damaged harness section. |
Model Compatibility, Replacement Considerations, and Installation guidelines
The 316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch functions as the low-voltage and high-voltage interconnect between the user controls, spark/ignition module, and the cooktop burners. It routes control and ignition signals, provides the switch that closes the ignition circuit, and carries the high-voltage lead to the electrode or ignitor assembly; compatibility depends on terminal count, connector shape, wire gauge, and insulation material. When evaluating interchangeability, compare pin spacing and keyed housings, confirm that the harness uses heat-resistant insulation and grommeted entry points for the same mounting locations, and verify that the ignitor switch actuates the correct circuit (some ranges use a direct-contact switch while others use a low-current sensing input to a control board). A harness that fits physically but has different terminal functions or missing shielding can produce intermittent ignition or damage to the spark module.
Replacement and installation require basic electrical verification and careful routing to avoid heat and mechanical abrasion.Disconnect power and document connector orientation before removal; test continuity between the switch terminals and the module pins and inspect for brittle insulation, corrosion, or soldered vs. crimped joints. During installation, seat connectors fully, preserve or replace any grommets and strain-relief clips, and route the harness away from hot surfaces and moving parts; secure fasteners so vibration does not loosen terminals. After installation, verify operation with a multimeter and a controlled ignition test rather than prolonged operation to confirm correct switching behavior and to avoid exposing new parts to thermal stress before confirming proper function.
- Compatibility checks: terminal count, connector keying, and insulation rating
- Common failure symptoms: intermittent spark, no spark, or shorted circuit at the switch
- Installation safeguards: grommets, strain relief, and secure crimps/solder joints
| Item | Description |
|---|---|
| Connector style | Match keyed multi-pin and blade terminals to prevent mis-wiring |
| wire & insulation | Use equivalent gauge with high-temperature insulation and routed through grommets |
| Verification | Continuity checks and brief ignition tests after secure mounting |
Q&A
What is the 316219004 Frigidaire wiring harness with ignitor switch and what does it do?
The 316219004 is an OEM replacement wiring harness assembly used on many Frigidaire/White-Westinghouse/Bosch-built ranges and cooktops. It includes the electrical leads and the ignitor switch (spark switch) that connects the control/spark module to the surface burner ignitors. The harness routes power and signals so that when you turn a burner control to “lite” the switch tells the spark module to produce the high-voltage spark at the electrode.
How do I know if this part is the correct replacement for my stove or cooktop?
Check the model number of your appliance (usually on a tag behind the oven door, on the frame, or on the back of the unit). Then compare that model number to the parts lists on Frigidaire’s parts website or a trusted parts supplier.you can also confirm by matching the old part number printed on your existing harness; if it’s 316219004 (or the supplier lists your appliance model as compatible), it’s the correct OEM part. If in doubt, supply your full appliance model to a parts dealer for verification.
What are common symptoms that indicate the wiring harness or ignitor switch is bad?
Common signs include: the burner clicking continuously without lighting; no clicking at all when a burner control is turned to “light”; intermittent ignition that works sometimes; visible burn,melting,or corrosion on the harness or switch; or a specific burner not producing a spark while others do. Note that these symptoms can also be caused by a failed spark module, damaged electrode, or gas supply issues, so a proper diagnosis is important.
Can I test the ignitor switch/harness myself and how?
Yes, if you have basic electrical tools. First disconnect power (breaker) and gas. Visually inspect for damaged wires or mating connectors.Use a multimeter (ohms/continuity) to check the switch: with the switch actuated (simulate the control knob position) the microswitch contacts should change state (open/close). Also check continuity to the ignitor electrode conductors.To test the spark module side you must restore power carefully and measure for correct control voltage per service sheet (or have a technician test).If you are uncomfortable or not confident with electrical measurements, hire a technician.
What tools and safety steps are needed to replace this harness?
Tools: Phillips and flathead screwdrivers, nut drivers or socket set (usually 1/4″-5/16″), needle-nose pliers, wire-cutters/strippers (if needed), and a multimeter for verification. Safety steps: turn off electrical power at the breaker, shut off the gas supply, allow all parts to cool, photograph or label connections before disconnecting to ensure correct reassembly, and avoid damaging grounding straps. if you smell gas after reassembly,stop and contact a qualified technician.
How long does replacing this part usually take and is it an advanced repair?
For someone with basic appliance repair experience the job typically takes 30-60 minutes: remove the back panel or cooktop, disconnect the old harness, install the new harness and switch, and reassemble. It’s a moderate repair that requires electrical safety awareness and careful routing of wires. If you are unfamiliar with appliance internals or gas/electrical safety, it’s best to hire a qualified technician.
After installing the new harness the burners still won’t light – what else should I check?
Check the following: spark electrode condition and gap (clean or replace if fouled or cracked), spark module functionality, continuity of the new harness connections and proper grounding, that power and gas supply are present and the gas safety valve is functioning, and that the burner head and ports are clean and seated correctly. If clicking is present but no spark is visible, suspect the spark module or electrode wiring/ground. When in doubt consult a service manual or technician.
Is 316219004 an OEM part and are aftermarket options acceptable?
316219004 is an OEM frigidaire part number. OEM parts ensure correct fit, wire colors, connector types and usually have factory quality standards. Aftermarket harnesses may be available and can be less expensive,but verify fit,connector compatibility,and quality before buying. For safety and long-term reliability on gas appliances, many technicians recommend using OEM or high-quality equivalent parts.
