316580615 Frigidaire Range Spark Ignition Switches with Wire Harness is a combined electromechanical component assembly used on Frigidaire gas ranges; it consists of momentary spark ignition switches (the user-actuated switch elements located under the control knobs) integrated with a multi-conductor wire harness that provides the electrical connections to the ignition module, control board and burner electrodes. As a replacement part, the assembly includes the contact switches, connector housings and lead wires sized and routed to match the original equipment layout so technicians can install it without rewiring the appliance.
Functionally, the ignition switch assembly serves as the local user interface that initiates the spark sequence for surface burners and, depending on model, the oven burner. when a switch is actuated, it completes the control circuit that tells the ignition module to generate high-voltage pulses to the spark electrodes while the gas valve is signalled to open; the wire harness carries the low-voltage control signals, ground references and any interlock feedback to other systems. The switch and harness therefore interact with the ignition/spark module, main control board, gas valve and the spark electrodes themselves, and their condition affects ignition timing, spark continuity and safety interlocks in the overall appliance system.
In this article readers will find a technical overview of how the 316580615 ignition switch and harness operate, guidance on model compatibility and connector pinouts to help identify correct replacements, typical failure modes and observable symptoms (such as no spark, intermittent sparking, or continuous sparking), and practical troubleshooting and testing steps including visual inspection, continuity and voltage checks using a multimeter. the article will also cover considerations for replacement-OEM versus aftermarket fit, harness length and routing, connector mating, and basic safety precautions (power and gas isolation, insulated tools)-so technicians, engineers and informed appliance owners can diagnose and plan repairs with an understanding of the component’s role and constraints.

Function and Role of the Spark Ignition Switch and Wire Harness in Frigidaire Gas Range Control Systems
The 316580615 Frigidaire Range Spark Ignition Switches with Wire Harness serve as the user‑facing control that routes mains power to the ignition system and provides the switching logic for individual burners. In typical Frigidaire gas ranges this component is a rotary/momentary contact switch that, when the knob is depressed or turned to the light position, sends 120 VAC into the spark/ignition module and simultaneously completes the circuit to the burner electrode. The attached wire harness carries the switched voltage and signal returns between the switch, the ignition module, burner electrodes, and the valve interlocks; because the assembly includes matched connector shapes, pin counts, and color‑coded leads, correct mechanical and electrical compatibility with specific model families is essential for reliable operation.
Behavioral and failure modes are generally straightforward to diagnose: a faulty switch or damaged harness can cause a single burner to fail to spark, continuous sparking, or intermittent operation across multiple burners if the harness has a short or high resistance joint. practical troubleshooting steps for a technician include visually inspecting the harness for chafing or corrosion, verifying continuity across switch contacts with the control actuated, and measuring the presence of line voltage at the switch input and the switched output when the control is operated. Replacement with the correct 316580615 assembly restores the factory terminal layout and wiring routing, minimizing the chance of miswiring; technicians should always de‑energize the appliance before performing continuity checks or harness replacements.
- Common symptoms: no spark at one burner, constant sparking, arcing between connectors, or multiple burners affected.
- Key checks: harness continuity, connector integrity, terminal voltage with control actuated, and insulation condition.
- Compatibility notes: match connector shape, terminal count, and wire color codes to the appliance model.

How the 316580615 Frigidaire Range Spark Ignition Switches with wire Harness Operate Within Burner Valve and Control Circuitry
The 316580615 Frigidaire Range Spark Ignition Switches with Wire Harness are momentary contact switch assemblies that connect the user control (knob) to the rangeS ignition and control circuitry via a molded harness.When the control is moved to a lighting position the switch closes and completes a control circuit to the ignition module, wich then produces high-voltage pulses to the igniter electrodes until the burner lights. The harness provides the correct pinout, wire lengths and connector style for direct replacement on compatible Frigidaire models, and the switch often carries additional conductors for interlocks or sensing feedback required by the range control board or gas valve safety circuit.
Technically,these switches behave as low-impedance closed contacts in the actuated state and open-circuit when released; a simple continuity test should show near-zero ohms when actuated and very high resistance when released. Common service checks include verifying continuity across the relevant harness pins, inspecting for broken or corroded terminals, and confirming the switch mounts and grounding are secure to avoid intermittent sparking or failed ignition. practical failure modes include worn contact surfaces, cracked insulation causing leakage, or connector mismatch-technicians should compare harness colors, connector shape and pin functions to the original and, if necessary, trace the control circuit back to the ignition module to distinguish switch failure from module or electrode faults.

Electrical and Mechanical failure Symptoms: Ignition Signal Loss, Intermittent Sparking, and Diagnostic Indicators
The 316580615 Frigidaire Range Spark Ignition Switches with Wire Harness function as the user-actuated electrical interface that transmits knob position to the stove’s spark generator. The rotary switch contains multiple contact poles and wiper assemblies that must make reliable closures to send a clean trigger signal; the attached wire harness provides factory-matched terminals and color-coded leads for direct replacement and correct pinout compatibility with Frigidaire ranges using the same connector pattern. Mechanical wear of the shaft or wipers, contamination of contact surfaces, broken terminals, or harness connector corrosion all alter the electrical continuity and timing of the signal, producing symptoms that mimic ignition module or electrode failures even when those components remain serviceable.
Typical diagnostic indicators distinguish electrical contact failure from downstream module or electrode faults: intermittent sparking frequently enough correlates with loose or fatigued harness terminals and can be reproduced by wiggling the switch or wiring under power-off continuity testing; complete ignition signal loss usually shows an open circuit on the switch poles when actuated. Practical checks for technicians include visual inspection for pitted or burned contacts, continuity measurements across switch poles in each knob position with the circuit de-energized, verification of secure mating at the harness connector, and voltage checks at the switch output under the manufacturer’s service conditions. For example, if the switch shows proper continuity when actuated but no spark appears at the electrodes, the failure is more likely in the ignition module or high-voltage wiring rather than the switch itself.
- No spark at any knob position: open circuit or broken harness conductor.
- Intermittent sparking: loose terminals,cracked solder joints,or worn wiper contacts.
- Continuous sparking or arcing at the switch: shorted contacts or melted insulation causing leakage paths.
- Visible heat damage or discoloration: high-resistance contact points producing localized heating.
| Item | Description |
|---|---|
| Switch continuity | Measure with power off; should change state cleanly between detents when rotated. |
| Harness connector | Inspect for bent pins, corrosion, and secure latch engagement to prevent intermittent opens. |
| Mechanical shaft | Check for smooth rotation and minimal axial play; excessive play indicates worn internals affecting contact alignment. |
Compatibility, Replacement Procedures, Installation Best Practices and Troubleshooting Diagnostics for 316580615 Assemblies
The 316580615 Frigidaire Range Spark Ignition Switches with Wire Harness functions as the mechanical-electrical interface that routes the cooktop knob position to the ignition system. The assembly contains a multi-position switch and a keyed wiring harness whose pinout and mounting features must match the range control panel; mismatched shaft length,mounting tabs,or connector orientation will prevent proper installation even if the electrical contacts are similar. Typical failure modes include worn contact faces, burned or corroded terminals, plastic deformation around the shaft, and intermittent continuity caused by carbon tracking-each of which can produce no spark, continuous sparking, or erratic ignition behavior depending on whether the switch fails open, closed, or intermittently under load.
- Disconnect power to the appliance before any work; verify power isolation with a meter.
- Remove knobs and bezel, note or label wires and connector orientation, then unplug the harness from the back of the switch.
- Inspect the harness and connector for melted plastic, bent pins, or discoloration before swapping parts.
- Install the replacement, secure mounting hardware to factory torque or snugness to avoid warping, reattach the harness, restore power, and perform a functional test of each burner.
Use a digital multimeter for diagnostics: with the switch actuated you should observe low resistance (near-continuity) between the appropriate terminals and an open circuit when released; intermittent readings or high resistance indicate contact degradation. If the assembly produces continuous sparking after replacement, check for a shorted lead, a misrouted harness that grounds to chassis, or a misaligned knob that keeps the switch in the actuated position. Always compare the replacement assembly’s connector pinout and mechanical footprint to the original and consult the appliance wiring diagram for the specific Frigidaire model; where possible, use OEM-matching harnesses to avoid unexpected conductor swaps or reversed signals during installation.
| Item | Description |
|---|---|
| Compatible Models | Ranges using the same switch footprint and connector; verify by model plate and harness pinout rather than visual similarity alone |
| Common Symptoms | No spark, continuous spark, intermittent ignition, or loose knob feel |
| Quick Diagnostic | Visual inspection, continuity check across actuated terminals, and confirmation of correct harness pin mapping |
Q&A
What is part 316580615 and what does the spark ignition switch with wire harness do?
Part 316580615 is a Frigidaire OEM spark ignition switch assembly with its attached wire harness. The ignition switch is the user-controlled selector on the cooktop that sends the signal/power to the spark module and gas valve so the burner will spark and release gas. The harness provides the connectorized wiring that links the switch to the range’s ignition system and control components.
How do I know if the ignition switch (316580615) is bad?
Common symptoms of a failing ignition switch include a burner not sparking or not clicking when the control knob is turned, intermittent sparking on certain knobs, or complete failure of a burner to ignite while others work. Visually inspect the switch and harness for burned contacts, melted insulation, or corrosion. Confirm with electrical testing (continuity or voltage) before replacing-if the switch does not make the expected electrical connection when actuated, it needs replacement.
Can I replace the ignition switch and harness myself, and what safety steps should I follow?
Yes – a competent DIYer can usually replace this part.Critically important safety steps: disconnect the range from power (unplug or switch off the circuit breaker) and, for gas ranges, turn off the gas supply at the shutoff valve. Work in a well‑ventilated area and avoid creating sparks near any gas leaks. If you are not agreeable working with gas or house wiring, hire a qualified technician.
What tools and materials do I need to replace 316580615?
Typical tools: a set of screwdrivers (Phillips and flat), nut driver or socket set for panel screws, needle‑nose pliers, and optionally a multimeter for testing.Keep the replacement part ready and have zip ties or electrical tape available to secure wiring if needed. Always keep panels and fasteners organized for reassembly.
How do I test the ignition switch and harness with a multimeter?
With power off,remove the switch/harness assembly so you can access terminals. Set the multimeter to continuity or low‑ohm range. Identify the switch terminals from the wiring diagram or by noting which terminals change when the knob is turned. With the knob actuated (simulating the ON position),the correct terminal pairs should show continuity/very low resistance. With the knob off, they should be open. For live voltage checks (if you are experienced), reapply power and measure per the wiring diagram-but avoid live testing unless you are trained.
Will the replacement part fit my range model?
Compatibility depends on your exact Frigidaire model.316580615 is an OEM part used on many Frigidaire ranges, but you should confirm compatibility by checking your appliance model number and the manufacturer parts list or by using an online OEM parts lookup.also compare connector shapes,mounting tabs,and wire colors to ensure a proper physical fit.
After installation I still have no spark - what should I check?
If replacing the switch does not restore sparking,check these items: the wire harness connections (tight and corrosion‑free),the spark module/igniter assembly,the spark electrode gap and condition (clean and properly positioned),the gas valve/solenoid,and fuses/circuit breakers.Use the range wiring diagram to verify voltage is arriving at the switch and leaving to the module when the knob is turned.If multiple burners are dead, suspect the spark module or power supply; if only one is dead, suspect that burner’s igniter or electrode.
How long do these ignition switches last,and are there maintenance tips to prolong life?
Switch lifespan varies with use but commonly lasts several years. To prolong life: keep knobs and control areas clean and dry (food and moisture can corrode contacts), avoid forceful turning of knobs, and inspect wiring periodically for wear. If an electrode or burner spills occur, clean promptly to prevent conductive residues from causing arcing or damage to the switch and harness. Regular maintenance of the burners/igniters reduces stress on the ignition components.
