316580615 Frigidaire Range Spark Ignition Switches with Wire Harness is a combined electromechanical switch and pre-wired connector assembly used on Frigidaire gas ranges; it provides the user interface and electrical pathway required to initiate the burner ignition sequence. As a component, the assembly typically consists of a momentary or position switch element integrated with a multiconductor wire harness and connector(s) that mate to the appliance’s control circuitry and spark-generating module.
Inside the appliance the ignition switch and harness complete and route low-voltage control signals from the range control or knob assembly to the spark generator (ignition module) and, indirectly, to the gas valve control system. The switch closes the ignition circuit when a burner control is operated, allowing the spark module to produce high-voltage pulses at the electrode while the harness provides the physical and electrical connection to the control board, ground, and any safety interlocks. In practice the assembly interfaces with the spark module, burner electrodes, gas valve circuitry, control panel, and chassis ground, so its electrical continuity, connector integrity, and correct routing are essential to reliable ignition and safe operation.
In this article readers will find a technical clarification of how the 316580615 switch and harness function electrically and mechanically, guidance on compatibility and identifying the correct replacement, common failure symptoms to recognize (such as no spark, intermittent spark, visible arcing or burned connectors), and a structured approach to troubleshooting including visual inspection, continuity and voltage checks, and isolating the switch from the spark module and gas valve. The article will also cover practical replacement considerations such as connector orientation, harness routing and retention, grounding, and post-replacement verification steps to confirm restored ignition performance.

Functional Role and Electrical Interface of the Range Spark Ignition switch and Wire Harness
316580615 Frigidaire Range Spark Ignition Switches with Wire Harness serve as the user-operated electrical interface that routes line power from the range controls to the spark generation circuitry and, when required, to the gas valve control circuit. The ignition switch provides momentary or maintained contact depending on the control position, and the attached wire harness groups the individual conductors into a keyed connector that preserves the factory pinout and color coding. In practice this assembly isolates the low- and line-voltage paths, simplifies replacement, and assures that a given control knob energizes the correct igniter and valve coil; mismatched harnesses or worn switch contacts commonly produce burner-specific failures or intermittent sparking during ignition cycles.
From a troubleshooting and compatibility standpoint, technicians should treat the switch and harness as a combined functional unit: verify continuity across the switch when actuated, confirm presence of control circuit supply (typically line-level, e.g., ~120 VAC for the module/control side) and check that the harness terminals are free of corrosion or heat damage. Common field symptoms tied to faults in this assembly include a single burner failing to spark, continuous sparking after release, or ignition only while applying additional pressure to the knob. Replacing the assembly with the correct OEM part number ensures matching connector geometry and terminal assignment; if an exact harness is not available, document and reproduce the original wiring colors and pin functions to maintain safe operation.
- Key behaviors and checks: momentary contact to spark module, contact wear causes intermittent operation, harness preserves pinout and ground reference.
- Common symptoms: no spark on one burner, continuous spark, intermittent ignition, or physical signs of heat/corrosion at connector.
- basic tests: continuity of switch under actuation, voltage presence at COM and output terminals, visual inspection of wire integrity.

How the 316580615 Frigidaire Range Spark Ignition Switches with Wire Harness Works Inside the Appliance
The 316580615 Frigidaire Range Spark Ignition Switches with Wire Harness function as the user-interface contact and wiring interface that enables the spark module to generate ignition pulses at a burner. When the control knob is rotated to the “ignite” position the switch closes a normally-open contact that routes line power (and in some designs a control signal) through the harness to the spark ignition module; the module then produces the high-voltage pulses to the electrode near the burner. The harness bundles the switch terminations with keyed connectors and color-coded conductors so the switch can be replaced as a single assembly without rewiring, and it also provides a durable mechanical mounting to resist vibration and heat inside the range cavity.
Technically, failures occur either at the switch contacts (pitting, loss of continuity) or along the harness (broken strands, melted insulation, poor connector contact). Technicians commonly verify operation by checking continuity across the switch terminals while actuating the knob and by measuring presence of mains voltage at the module connector when the switch is operated; absence of continuity or voltage indicates a switch/harness fault rather than the spark module. Practical signs that point to replacing the assembly include intermittent sparking, constant clicking with no ignition, or visible heat damage to the harness. Below are typical features and common symptoms to inspect during diagnosis:
- Features: normally-open switching, keyed multi-pin harness connectors, heat-resistant wire insulation.
- Symptoms: no spark, intermittent spark, audible clicking without ignition, melted connector insulation.
- Diagnostic checks: continuity test under actuation, voltage check at module connector, visual inspection for cracked wires or corrosion.
| Item | Description |

| Function | Close circuit to energize spark module when knob is in the ignite position |
| Typical tests | Continuity across switch terminals under actuation; mains voltage present at module connector |
| Common failure modes | Contact wear, broken or shorted conductors, connector corrosion |
Common Failure Modes and Diagnostic Symptoms of Spark Ignition Switches
The 316580615 Frigidaire Range Spark Ignition Switches with Wire harness act as the user-operated electrical interface that directs the low-voltage ignition signal from the control knob to the spark module and, in some designs, to the gas valve. Common mechanical and electrical failure modes include worn or pitted contact surfaces that develop high resistance or intermittent continuity, carbon tracking between terminals that causes unintended arcing, heat deformation of the actuator or housing, and damaged or shorted conductors in the integrated wire harness. Because this part combines the switch and harness, compatibility with terminal layout and wire colors is critical; incorrect replacements can lead to misrouted ignition signals, cross-fired burners, or excessive contact heating due to mismatched terminal spacing or insulation ratings.
Diagnostic symptoms map predictably to these failure modes and can be verified with simple tests. Use a multimeter to check continuity and resistance across the switch terminals while actuating the knob, perform a wiggle test on the harness to reproduce intermittent faults, and measure for voltage pulses at the switch output when the igniter is commanded. Practical examples: continuous sparking at a burner usually indicates a short to ground or a stuck/bridged contact (inspect for carbon tracking and melted insulation); no spark with a clicking knob can indicate an open contact or broken internal actuator despite a functional spark module; intermittent ignition frequently enough traces to lose terminals or corroded connectors in the harness. When testing, document wire colors and terminal positions before disconnecting to ensure correct reinstall and avoid creating new faults.
- No spark or no click when knob is turned – open switch contact or broken actuator
- Continuous sparking even when knob released – short to ground or bridged contacts
- Intermittent spark that responds to wiggling wires - loose terminal or damaged harness
- Sparking at wrong burner or multiple burners – misrouted harness or incorrect replacement
- Visible arcing, burnt plastic, or burning smell – carbon tracking or heat damage
| Item | Description |
|---|---|
| Symptom | Likely root cause / diagnostic check |
| No spark, no click | Open contact or broken actuator – check continuity and mechanical movement |
| Continuous spark | Short to ground or stuck contact – inspect for carbon deposits, measure resistance to ground |
| Intermittent ignition | Loose terminal or frayed wire in harness - perform wiggle test and visual harness inspection |
Compatibility, Replacement considerations, Installation Procedures, and Diagnostic Tests for Spark Ignition Switches
The 316580615 Frigidaire Range Spark Ignition Switches with Wire Harness functions as the user interface and electrical routing point between the control knob, the spark module, and the individual burner electrodes. These assemblies are multi-position rotary switches with an attached harness that preserves the factory terminal layout and conductor lengths; replacing only the switch without matching the harness can leave terminals misaligned or introduce intermittent connections. When evaluating compatibility, verify the appliance model number, terminal count and arrangement, mounting tab spacing, and harness connector type-technicians should compare the physical connector and pinout to the original unit rather than relying solely on part numbers to confirm fit and function.
- Symptoms: no spark at any burner, intermittent sparking, or a spark that clicks without ignition; inspect for visibly burned terminals or broken harness wires.
- continuity test: verify switch continuity across positions with a multimeter; expect open circuits when not selected and continuity between specific terminal pairs when a position is engaged.
- Voltage test: with power and gas disconnected for wiring changes, then reconnected for live testing, measure voltage at the switch output to the spark module (typically low-voltage control signal) and at the electrode during actuation to confirm spark delivery.
Installation requires orderly disassembly: remove the control knob, retain mounting hardware, disconnect the harness from the control board and burners, and transfer any retained clips or seals to the new assembly. Reconnect the harness observing the correct orientation of keyed connectors and secure mounting to avoid strain on terminals; a loose chassis or misaligned switch shaft will cause intermittent faults. for troubleshooting after installation, use systematic tests-continuity across switch positions, resistance checks for short circuits to chassis ground, and live verification of control voltage and spark at the electrode-to isolate failures to the switch, harness, or upstream control module.

| Mounting | Panel-mounted rotary with specific tab spacing; confirm screw size and orientation |
Q&A
What is part 316580615 (Frigidaire range spark ignition switch with wire harness) and what does it do?
316580615 is an OEM-style spark ignition switch assembly with its wire harness used on many Frigidaire ranges. The switch is the user-actuated electrical contact that sends power from the cooktop controls to the ignition module or igniter when a burner control knob is turned to the “light” or “spark” position, producing the spark that lights the gas burner.
What symptoms indicate the ignition switch is failing?
Common symptoms include: no clicking or spark when the burner knob is turned; intermittent sparking only on some knob positions; continuous clicking or arcing at the switch; burners that won’t light despite gas flow; visible burning, melting, or corrosion on the switch or harness. Note that similar symptoms can also be caused by a bad igniter, ignition module, wiring, or a blocked burner, so verify the switch before replacing it.
How can I test the ignition switch safely with a multimeter?
First disconnect electrical power to the range (turn off breaker). Remove the knob and access the switch. On continuity (or lowest ohms) setting, check for continuity between the common terminal and the output terminal while you actuate the switch (turn the control to the spark position). You should see continuity only when the switch is actuated. If you are qualified and must test for voltage, keep the range energized and measure for the expected AC output on the switch output terminal while the knob is turned - only do this if you are trained and pleasant working with live mains; or else, call a technician.
How do I confirm 316580615 is the correct replacement for my Frigidaire model?
Check the appliance model number (usually on a tag behind the oven door or on the range frame) and use an OEM parts lookup (Frigidaire’s parts site or a trusted parts supplier) to confirm compatibility. You can also compare the physical connector style and number of terminals/wires on the old switch to the replacement – the harness connector and terminal configuration must match.
What are the basic steps to replace the ignition switch and harness?
Basic replacement steps: 1) Turn off electrical power at the breaker (and turn off gas if you prefer). 2) Remove knobs and any required panels to access the switch. 3) Photograph/label wire locations. 4) Disconnect the wiring harness and mounting screws, remove the old switch. 5) Install the new switch,reconnect the harness in the same arrangement,secure mounting. 6) Reassemble panels and knobs, restore power, and test burners. Always follow the range manufacturer’s service instructions and safety precautions.
Do wire colors or connector types vary - how do I make sure I connect it correctly?
Yes – wire colors and connector types can vary between models and production runs. Before removing the old harness, take clear photos or label each wire and connector. The replacement harness is usually made to match the OEM connectors; match connectors and wire positions exactly. If splicing is unavoidable, use proper-rated wire and insulated crimp/solder connections and secure them with heat-shrink or proper insulating terminals.
Can the ignition switch be repaired or should I replace it?
Because ignition switches are low-cost and safety-critical, replacement is generally recommended over repair. Cleaning contacts can temporarily help if corrosion is minor, but internal wear, melted plastic, or intermittent electrical contact warrants replacement. Use an exact OEM or equivalent part to maintain safe operation.
What safety precautions should I follow when working on the ignition switch and harness?
Always disconnect electrical power at the breaker before opening the range. If you will be working near gas components, consider shutting off the gas supply.Avoid live-voltage testing unless you are trained and equipped to do so. After reassembly and restoring power/gas, check burner ignition and inspect for any unusual noises, smells, or gas leaks. If you smell gas or have doubts about your repair, shut off gas and power and call a licensed technician.
