316580615 Frigidaire Range Spark Ignition Switches with Wire Harness is an assembly used on Frigidaire gas ranges that combines one or more momentary-contact ignition switches with a pre-wired harness and connectorized leads.The component is an electromechanical switch and wiring assembly designed to interface user controls (knobs or switch actuation) with the range’s ignition circuitry, providing a reliable, serviceable connection point between the control surface and the ignition module or control board.
Inside the appliance, the ignition switch portion completes the control circuit when the user selects a burner or invokes the igniter, sending a control signal through the wire harness to the ignition module or control electronics. The ignition module then produces high-voltage pulses to the burner electrodes while the gas valve is commanded to open; the switch and harness therefore interact with the user control interface, ignition module, burner electrodes, gas valves and related safety interlocks or flame-sensing elements. From a technical perspective, the assembly must provide low-resistance contacts, secure connector mating, adequate insulation and strain relief, and correct routing to avoid chafing or heat exposure, since its electrical integrity and mechanical actuation directly affect ignition reliability and safe operation of the appliance.
In this article readers will learn how the 316580615 ignition switch and harness function within the ignition system, which Frigidaire models or control assemblies the part is intended to fit (compatibility considerations), common failure symptoms to recognize (open or intermittent circuits, continuous sparking, no spark, visible contact damage or wiring faults), basic troubleshooting checks a technician can perform (visual inspection, continuity and wiring checks, signal verification at the ignition module) and practical replacement considerations (matching connector and harness configuration, routing and mounting, contact condition and electrical ratings). The coverage is intended to provide the technical context needed for diagnosis, parts selection and safe replacement decisions without prescribing specific step-by-step procedures for any single model.

Function and Role of the Spark Ignition Switch Assembly in Frigidaire Ranges
The spark ignition switch assembly in Frigidaire ranges acts as the mechanical-electrical interface between the user control knob and the ignition system. The 316580615 Frigidaire range spark Ignition Switches with Wire Harness integrate a rotary contact block and a pre-wired harness so that knob position closes the correct circuit to the ignition module while providing the correct connections to the gas valve and spark electrode. By routing low-voltage control signals and preserving terminal mapping, this combined assembly ensures the ignition module produces timed high-voltage pulses at the electrode only when the valve is enabled, preventing simultaneous gas flow without ignition.
Functionally the switch should present low and stable contact resistance in the LIGHT/IGNITE position, survive thermal cycling near burner locations, and maintain secure connector terminations in the harness.Typical failure modes include intermittent continuity, corroded or burned contacts, broken harness conductors, and misrouted or incorrect connectors after replacement. Technicians diagnose faults by checking continuity across engaged switch contacts, verifying harness pinout against the range wiring diagram, and observing whether the ignition module receives the correct sequencing signal; selecting a replacement requires matching terminal count, mounting orientation, and harness length to avoid swapped signals or reduced spark energy.
- Common symptoms: clicking without spark, spark with no valve operation, or no clicking at all.
- Key checks: continuity under actuation, insulation integrity of the harness, and correct connector pin mapping.
- Compatibility checklist: terminal configuration,mounting bracket,harness length,and connector type.
| Item | Description |
|---|---|
| Terminal count | Determines which control signals are routed (match exact pin number). |
| Expected resistance | Closed-contact resistance typically near 0-5 Ω; significantly higher values indicate wear. |
| Harness length | Must allow correct routing to prevent tension or heat exposure on wires. |
How the 316580615 Frigidaire Range Spark Ignition Switches with Wire Harness Operates Within the Range’s Ignition Circuit
The 316580615 Frigidaire Range Spark Ignition Switches with Wire Harness function as the user-interface switch that commands the range’s ignition control to produce sparks. Mechanically, rotating or depressing the control knob closes the switch’s internal contacts and routes line power through the attached wire harness to the ignition module or directly to the valve/igniter circuit depending on the range design.The switch itself is a low-voltage/mains control device; the high-voltage pulses that produce the visible spark are generated by the ignition module transformer after it receives the control signal. In practical terms this means a failed switch or a corroded harness connector will prevent the ignition module from receiving power and will produce symptoms such as no clicking,no spark,or intermittent sparking even when the gas valve opens properly.
Technically,the switch is typically rated to switch household mains and is wired with distinct terminals for common,switched output to the ignition module,and often a terminal for the gas valve interlock. Compatibility depends on matching the harness pinout and connector style so the switch delivers the correct signals to the factory ignition control; the 316580615 assembly is designed to reproduce the OEM pin arrangement for supported Frigidaire ranges.For troubleshooting, a technician can use a multimeter to check for continuity across the switch contacts when actuated and measure the incoming and switched voltage (usually ~120 VAC on North American appliances) to confirm proper switching. Replace the switch or harness if connectors are melted, pins are bent, or intermittent continuity appears under mechanical stress.
- Function: closes circuit to enable ignition module and/or valve control.
- Behaviour: provides a stable mains/control signal; intermittent contacts cause loss of spark.
- Compatibility: must match OEM connector pinout and terminal positions for proper operation.
- diagnostics: multimeter continuity and AC voltage checks while actuating the control.
| Item | Description |
|---|---|
| Switched Voltage | Typically ~120 VAC to the ignition module or valve control terminal when actuated |
| Role | Control signal source that tells the ignition module to generate high-voltage spark pulses |
| Common Faults | open contacts, corroded pins, or broken harness wires causing no click/no spark symptoms |
Common Failure Symptoms and Diagnostic Indicators for spark Ignition Switches and Wire Harnesses
The 316580615 Frigidaire Range Spark Ignition Switches with Wire Harness serve as the user-interface contacts and wiring pathway that command the ignition module and gas valve; turning a control knob closes low-voltage switch contacts that signal the ignitor to generate spark at the electrode while the harness carries those signals reliably to the ignition assembly. In normal operation a technician will observe a distinct mechanical click from the switch and a visible, concentrated spark at the burner electrode; electrical failure modes include high-resistance or open switch contacts, shorted or chafed harness conductors, corroded connector pins, and heat-degraded insulation that changes the intended routing or timing of signals. Compatibility considerations focus on mechanical fit, connector pinout, and contact arrangement-substituting a switch/harness assembly that does not match the original pin configuration can produce intermittent or no ignition even if the switch itself appears to function.
- No audible click when a knob is turned but no spark at the electrode.
- Repeated rapid clicking with no sustained spark or ignition.
- Intermittent spark only when the control knob or harness is wiggled (indicates a loose or broken conductor).
- Visible arcing at connector pins, burned terminals, or melted insulation around the harness.
Diagnosing these indicators begins with visual and electrical checks: inspect connectors and insulation, then perform a continuity test across the switch contacts while actuating the knob to confirm closure and low contact resistance; use a multimeter to trace continuity through the harness to the ignition module and gas valve control. If the switch clicks but there is no electrode spark, verify the high-voltage output of the ignition module and continuity from the module to the electrode; if there is clicking only when the harness is manipulated, localize the open or intermittent conductor and repair or replace the harness. The table below summarizes common symptom-to-test correlations for quick reference and helps determine whether the switch, the harness, or the downstream ignition module and electrodes are the likely failure point.
| Item | Description |
|---|---|
| No click, no spark | Check switch continuity while actuating; open contact suggests switch replacement. |
| Clicking, no ignition | Measure ignition module output and harness continuity to electrode; module or electrode/harness fault likely. |
| Intermittent operation | Wiggle-test harness and connectors; repair broken conductor or corroded pin. |
Compatibility, Replacement Considerations, and Installation Procedures for 316580615 Assemblies
The 316580615 Frigidaire Range Spark Ignition Switches with Wire Harness serve as the user interface and electrical switching element that commands the spark generator for each burner. Functionally, the switch provides discrete switching contacts that close the spark circuit when a control knob is actuated; the attached harness routes those switched outputs to the spark module and to the valve control interlocks. Wear typically appears as high-resistance contacts, fractured harness conductors, or melted insulation from prolonged heat exposure; these failure modes produce intermittent sparking, no spark on a given burner, or cross-talk between burner circuits.Confirm compatibility by matching the physical connector layout, number and arrangement of terminals, and mounting footprint to the existing control panel-visual and pin-to-pin confirmation frequently outweighs model-only cross-references for correct installation.
Replacement and installation require basic electrical diagnostic checks and careful mechanical alignment. Before service,isolate electrical power and close the gas supply; then remove the knob and control panel to access the switch and harness. Verify harness pinouts with a continuity metre and document wire colors/positions before disconnecting. Mount the new switch using the original hardware so actuator orientation and panel gap remain identical; fully seat each blade connector and verify ground continuity. After reassembly, perform an operational test by energizing the control circuit (typically the appliance control is a 120 VAC supply) and actuating each burner circuit while observing spark behavior and measuring continuity across switching terminals. If intermittent operation persists after replacement, inspect the spark module and burner electrodes for insulation breakdown or grounding faults.
- Compatibility checks: part number match,terminal count/layout,harness color/pin mapping,and mounting hole spacing
- Diagnostic steps: measure continuity closed vs. open, inspect for heat damage, verify connector retention
- Installation steps: disconnect power and gas, label wires, transfer or replace mounting hardware, seat connectors, test under power
| Item | Description |
|---|---|
| Connector type | Multi-blade terminals on an integrated harness designed to mate with Frigidaire control wiring |
| Voltage rating | 120 VAC control circuit (typical appliance control voltage) |

Q&A
What does the 316580615 Frigidaire range spark ignition switch with wire harness do?
The ignition switch is the user actuator behind a control knob that signals the igniter circuit to create a spark at a burner electrode. The included wire harness carries that electrical signal from the switch to the igniter module/transformer and to the gas valve interlocks. Replacing this assembly restores the electrical connection and switching action required for reliable ignition.
What are common symptoms that this ignition switch assembly is failing?
Typical symptoms include: no clicking or sparking when a knob is turned, intermittent ignition (works sometiems), continuous sparking after releasing the knob, a loose or wobbly knob that won’t actuate the switch, or a burner that will not light although gas is present. These signs commonly indicate a faulty switch or harness connection.
How can I test the switch and harness to confirm they are bad?
First disconnect power to the range. Remove the control panel to access the switch and harness. With a multimeter set to continuity or ohms,check that the switch changes state when actuated: you should see continuity between the common terminal and the appropriate output terminal only when the knob is in the ignition position. Inspect the harness for broken wires,melted insulation,or loose terminals. If the switch fails to change state or you find open circuits, the assembly is defective. If the switch tests good electrically but there is no spark, test the igniter/transformer and electrode wiring next.
Is the 316580615 an OEM part and will it fit my Frigidaire range model?
316580615 is an OEM Frigidaire ignition switch assembly in many parts catalogs, but compatibility depends on the range model and production year. Always verify fit by matching the part number to your appliance model number (found on the range tag or owner’s manual) or by checking the parts diagram from Frigidaire or an authorized parts dealer. Do not rely on visual similarity alone-connector type and terminal layout must match.
Can I replace the ignition switch and harness myself? What tools and safety steps are needed?
Homeowners cozy with basic appliance repair can often replace this part. Safety steps: disconnect the range from electrical power (unplug or turn off the breaker) and, if working near gas valves or lines, turn off the gas and consider calling a qualified technician. Typical tools: screwdrivers, nut drivers, needle-nose pliers, and a multimeter for testing. Replacement usually involves removing the control panel,unplugging the old harness connectors,swapping the switch assembly,and reassembling. If you are unsure about working around gas components or house electrical wiring, hire a qualified technician.
What should I check if I install the new 316580615 and the burner still won’t ignite?
After installing the switch and confirming proper wiring and secure connectors, check in this order: 1) Verify the range has power and the igniter transformer/igniter module is receiving the switch signal. 2) Inspect burner electrodes for cracks or carbon buildup and ensure they are properly positioned.3) Test the igniter/transformer output for high-voltage pulses. 4) Confirm the gas valve opens when the knob is held in the ignite position (listen for gas flow and check for a smell of gas only when safe to do so).If the switch works but there is no spark or no gas flow, the issue is likely with the igniter module, transformer, electrode, or gas valve-consult a technician if needed.
Are there any wiring or connector differences I should be aware of when replacing the harness?
Yes-wire lengths, connector types, terminal pinouts, and wire colors can vary between models. Before removing the old harness, take photos or label each connection so you can reinstall exactly as found. Do not cut and splice wires to force a fit; use the correct harness for your model. If connectors don’t match, obtain the correct OEM harness or a verified cross-reference replacement to avoid miswiring and potential damage.
