316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch is a factory-style wiring assembly that combines signal and power conductors with a mechanical or electronic ignitor switch used in Frigidaire range cooktops. It typically includes insulated leads, connector terminals or plugs, strain reliefs, and the switch element that completes the ignition circuit; the assembly is intended to replace the original harness without modification and to restore the electrical path between user controls, the spark or hot-surface ignitor, and the range’s control electronics.
Inside the appliance the harness routes electrical power and control signals between the cooktop burners,the ignitor/spark module or hot-surface ignitors,the gas valve interlocks and the range’s control board or user interface. Depending on the range design, the assembly carries mains voltage for valve and ignitor power and low-voltage control signals for the switch and sensing circuits; it also provides mechanical mounting and positioning so that connectors remain secure in a high-heat environment. Because it interfaces with ignition, safety interlocks and control electronics, correct wiring, insulation, routing and connector integrity are crucial for reliable ignition and to avoid arcing, unintended continuity, or heat-related degradation.
In this article you will find a technical overview of the 316219004 harness’s function and how it integrates with common Frigidaire range subsystems, guidance on compatibility considerations and how to verify correct part selection, typical failure symptoms (for example no spark, intermittent ignition, visible heat damage or corrosion at terminals), recommended diagnostic checks such as visual inspection and electrical continuity and voltage verification, and practical replacement considerations including matching connector types, wire lengths, thermal ratings and safety precautions to observe before and after installation. The emphasis will be on information useful to technicians, engineers and appliance owners for accurate diagnosis, safe handling and correct component replacement.

Function and Role of the Ignitor Switch Wiring Harness in Frigidaire gas Ranges
The 316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with ignitor Switch is an assembled wiring loom that integrates the user-facing ignitor switch with the electrical connections that feed the spark/ignition module, oven and cooktop ignitors, and gas valve circuits. Functionally, the harness routes line voltage and return paths, provides the switch contact that enables the spark or hot-surface ignitor when a burner or oven control is actuated, and carries grounding and interlock signals required by the range control system. In practical terms this means the harness must preserve correct polarity and connector pinouts so the control module sees the expected closed/open switch behavior and the ignitor receives the necessary 120 VAC pulse or continuous feed depending on the design of that Frigidaire range model.
- Integrated ignitor switch contact that closes on knob actuation to energize spark/hot-surface circuits.
- Multi-conductor leads and OEM-style connectors matched to Frigidaire modules and valve coils.
- Heat- and grease-resistant insulation and routing provisions to prevent chafing and thermal degradation.
- Common symptoms of harness failure: no spark at ignition, continuous sparking, or intermittent ignition; these are diagnosable with continuity checks and voltage measurements at the connector.
| Item | Description |
|---|---|
| Conductors | Typically multiple insulated leads for 120 VAC power, neutral/return, and ground; wire gauge matches current load of ignitor and valve circuits. |
| Connectors | OEM female/male nylon connectors keyed to mating components; pin count must match original harness for compatibility. |
| Function | Transfers switch closure signal and power to ignitor/spark module and associated gas valve circuits while providing mechanical mounting and strain relief. |
Compatibility checks before replacement include confirming connector styles, wire count, mounting points, and insulation routing to match the original harness; incorrect pin mapping or an unsecured harness can produce misbehavior such as continuous ignition or failure to light. For field diagnosis, a technician can measure for continuity across the ignitor switch, verify 120 VAC at the ignitor lead only when the switch is actuated, and inspect the harness for heat damage or brittle insulation; replacing the assembly with the correct 316219004 harness typically restores proper electrical behavior when the underlying control and ignitor components are known-good. During installation, secure the harness with original clips and keep leads away from high-heat flues to prevent premature failure.
How the 316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch Works Inside the appliance
The 316219004 Frigidaire Stove Oven Range Cooktop wiring Harness with Ignitor Switch is a multi-conductor harness that routes control and power signals between the range control/ignition module, surface burner ignitors, and the manual ignitor switch. Internally the harness combines insulated conductors, spade and plug-style terminals, and a serviceable switch assembly so that the control knob or front-panel switch can complete the ignition circuit without exposing high-voltage wiring at the user interface. In practice this part translates the control logic (or user action) into a switched feed to the spark generator and to associated valve coils or safety interlocks,so proper mating of connectors and intact insulation are essential for reliable ignition and appliance safety.
During operation the ignitor switch closes the circuit that allows the spark generator to pulse the ignitors while the harness supplies return paths and, where applicable, line voltage to valve coils or sensing elements. Technicians should expect to see continuity through the switch terminals when actuated, low-resistance connections across harness splices, and no signs of heat damage at terminal housings. Common diagnostic checks include verifying continuity and contact condition at each spade terminal, confirming the presence of the correct control voltage at the harness connector with the control in the ignite position, and inspecting for chafing or melted insulation near burner openings. Practical symptoms that point to a harness or ignitor-switch fault are intermittent sparking, no spark when the switch is actuated, or visible burning at connector interfaces:
- Intermittent ignition or weak sparking under load
- No continuity through switch when actuated
- Visible melting, corrosion, or loose spade terminals
- Correct control voltage present at module but not at ignitor terminals
| item | Description |
|---|---|
| Connector types | Multiple spade and plug-style terminals for modular replacement and serviceability |
| Function | Routes ignition control signal and power to ignitors and valve/interlock circuits |
| Typical tests | Continuity through switch (ohms), presence of control voltage during ignition, visual terminal inspection |
Common Failure Symptoms and Electrical Fault Indicators for the wiring Harness and Ignitor Assembly
The 316219004 frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch routes power and the ignition control signals between the cooktop switches, spark module/ignitor, and the gas valves or hot-surface elements.In normal operation the harness provides a low‑impedance, mechanically secure path so the ignitor switch can briefly apply voltage to the spark generator; failures in the harness or switch typically change that behavior - either opening the circuit so no spark is produced, or creating a short/ground that causes continuous sparking or tripping breakers. Technicians should consider connector corrosion, broken conductor strands, and melted insulation as common mechanical causes that alter electrical characteristics and compatibility with the stove’s ignition module and control circuitry.
- No spark or burner fails to ignite – open circuit in harness, broken switch contact, or disconnected terminal.
- Continuous sparking – stuck switch contact or short to chassis/ground keeping the ignitor energized.
- Intermittent ignition or long ignition delay – high resistance in a connector or partially broken conductor increasing voltage drop.
- Visible arcing,burned insulation,or discolored terminals - insulation breakdown or short risk requiring immediate replacement.
- Circuit breaker trips or blown fuses when igniting - definitive sign of a short to ground or conductor insulation failure.
Diagnosing faults requires a combination of visual inspection and electrical verification: perform a continuity check across the switch actuator, measure for unintended continuity to chassis (short to ground), and confirm the presence or absence of expected voltage at the ignitor connector during an ignition attempt (use a multimeter or test lamp rated for the appliance line voltage). For example, if 120 VAC is present at the module but no spark occurs, the harness conductor or ignitor electrode is highly likely open; if voltage is present continuously at the ignitor when no switching action occurs, the switch contacts or wiring insulation are suspect. Replace the harness assembly when you find burned terminals, exposed conductors, or intermittent continuity that cannot be reliably repaired.
| Item | Description |
|---|---|
| Open circuit at ignitor | No continuity to ignitor terminal; causes no spark despite correct control signals |
| Short to ground | Continuity from hot conductor to chassis; causes continuous sparking or tripped breakers |
Replacement Considerations, Compatibility and Installation Best Practices for the Harness and Ignitor Switch
The 316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch provides the electrical path and switching interface between the range control and the spark ignitor; it contains the switch contacts, insulated conductors, and a connector keyed to Frigidaire OEM layouts. This harness is engineered for elevated temperatures and frequent cycling,so matching the original part number reduces the risk of incorrect terminal spacing,connector pinout mismatch,or insufficient insulation that can produce arcing or intermittent ignition. In practice, a failed harness or ignitor switch presents as no spark at the burner, intermittent sparking, or an ignitor that continues to run after the knob is released - symptoms that are best diagnosed by inspecting connector integrity, checking continuity across switch terminals, and comparing the replacement harness to the original assembly before installation.
Follow a verified safety and compatibility checklist during replacement:
- Disconnect power and gas before any work; confirm circuits are dead with a meter.
- Compare connector types, pin counts, and wire lengths to ensure the replacement matches the original harness.
- Inspect insulation, heat sleeves, and terminal crimp quality; perform continuity checks on each conductor and verify switch operation with an ohmmeter while actuating the control.
- Route and secure the harness away from hot surfaces and moving parts, use heat-resistant ties, and avoid sharp bending at terminals to prevent fatigue.
After installation, verify safe operation by confirming proper spark timing and that the switch opens and closes as intended; consult the appliance wiring diagram for terminal identification and switch contact ratings before substitution.
