316580615 Frigidaire Range Spark Ignition Switches with Wire harness are an electromechanical switch assembly combined with a pre-terminated wiring harness designed for Frigidaire gas ranges; the assembly contains the user-actuated contact(s) and the wiring needed to connect the switch to the range’s ignition circuitry.This component is a serviceable control element rather than a sensor or a high-level control board, and it provides the primary user interface for initiating spark generation at one or more surface burners.
Inside the appliance the switch and harness act as the interface between the user control (knob or control panel) and the range’s ignition module and gas valve circuitry. When the control is moved to the lighting position the switch closes to supply the ignition circuit with the control signal or power needed by the spark generator; the harness transmits that signal to the module and provides the return path. As an inevitable result the switch interacts electrically with the spark/ignition module, the burner electrodes, and indirectly with the gas valve solenoid; mechanically it is indeed subject to repeated actuation, and electrically it must maintain low-resistance contacts and intact insulation to avoid arcing or intermittent operation.
In this article readers will gain a technical understanding of how the 316580615 switch and harness function within a Frigidaire range, how to verify compatibility by checking OEM part numbers, connector pinouts, and mounting features, and how to recognize common failure symptoms such as no spark, intermittent ignition, audible arcing, or visible contact damage. The article will also cover practical troubleshooting checkpoints that a technician or knowledgeable appliance owner can use-visual inspection, continuity and voltage checks, and harness integrity assessments-along with considerations for safe and correct replacement including part selection, routing and securing the harness, and post-replacement verification. These sections are intended to support diagnostic efficiency and correct component replacement without prescribing a specific repair procedure in this introduction.

Function and Role of the Spark Ignition Switch and Wire Harness in Frigidaire Gas Ranges
The spark ignition switch and wire harness form the electrical interface that initiates burner ignition in many Frigidaire ranges. The assembly identified as 316580615 Frigidaire Range Spark Ignition Switches with Wire Harness contains the user-actuated switch and the bundled leads that connect that switch to the spark generator/igniter and to safety interlocks. When the control knob is rotated or pressed, the switch provides a momentary contact closure that signals the ignition module to produce high-voltage pulses at the burner electrodes; the harness routes those control and ignition leads with heat-resistant insulation and keyed connectors to maintain correct polarity and secure mechanical mounting. mechanical wear,carbon buildup on contacts,or damaged insulation in the harness will change contact resistance or continuity and directly affect spark intensity and timing,which explains common symptoms such as weak sparking or intermittent ignition clicks without flame establishment.
Technicians should treat the switch/harness as a combined electrical-mechanical subsystem: the switch delivers the control logic to the ignition module while the harness preserves signal integrity and isolation in a high-temperature surroundings. For replacement or compatibility checks, verify the OEM part number and connector pinout before installation, and compare mounting tabs and wire color coding to the original assembly to avoid miswiring the spark generator or safety circuits. practical diagnostics include verifying switch continuity with a multimeter while actuating the control,inspecting harness terminations for heat damage or corrosion,and confirming the ignition module produces high-voltage pulses when given a closed switch input; if the switch shows intermittent continuity under load or the harness has melted insulation,replacing the full 316580615 assembly is typically the most reliable corrective action to restore consistent ignition behavior.
- Integrated switch and harness reduces multiple connection points and simplifies replacement.
- Keyed connectors and heat-resistant insulation designed for proximity to burners.
- common failure modes: contact wear, melted insulation, corroded terminals, broken wires at strain points.

How the 316580615 Frigidaire Range Spark Ignition switches with Wire Harness Operate Within the Ignition Circuit and Control Module
The 316580615 Frigidaire Range Spark Ignition Switches with Wire Harness serve as the user-actuated interface between the range control knobs and the ignition circuitry. Mechanically, the switch closes specific contact paths as the knob is turned to a burner position, routing line voltage through the attached wire harness to the ignition control or spark generator; in multi-pole configurations the same part can provide separate circuits for spark and for the gas valve interlock. In practice this means the switch must present the correct continuity and voltage to the ignition module when in the “spark” positions and maintain isolation when off, so the connector pinout, contact rating, and mechanical detent positions must match the appliance’s wiring harness and control logic for proper operation.
The switch’s behavior directly affects the ignition control: the control module senses the switch closure and either triggers the high-voltage spark generator or allows the valve coil to energize in sequence. Common compatibility and failure considerations include mismatched terminal assignments, burned or pitted contacts that produce intermittent sparking, and harness damage that interrupts the 120 VAC feed; technicians typically verify terminal voltages with a meter and check continuity across specific switch terminals in each knob position to isolate a defective switch from a faulty ignition module. Practical diagnostics: if the control never sees line voltage on the expected harness pin when the knob is turned, replace the switch/harness assembly with the correct part number and pin configuration; if voltage is present but no spark occurs, pursue the ignition control or the igniter itself.
- Function: closes circuits to send line voltage to ignition control or spark generator.
- Behavior: multi-position contact closures mapped to burner and off states.
- Compatibility: must match terminal layout, contact ratings, and harness connector.
- Symptoms of failure: no spark, continuous spark, or intermittent ignition.

Common Failure Symptoms and Electrical/Mechanical Diagnostic Indicators for Spark Ignition Switches
The 316580615 Frigidaire Range Spark ignition Switches with Wire Harness serve as the user interface between the control knob and the spark module, completing the electrical path that produces ignition pulses at the burner electrode. In operation the switch provides a momentary closure that routes the range’s ignition supply to the spark generator and ofen carries the selector signal to the valve circuit; the attached wire harness preserves the factory pinout and grounding so replacement compatibility depends on matching the harness connector and terminal layout.Technicians should verify that the switch physically fits the control panel and that wire colors and terminal positions match the original assembly to avoid mis-wiring the spark module or gas valve circuits.
common failure modes present either as electrical faults (open circuits, high contact resistance, intermittent continuity, or burned contacts producing arcing) or as mechanical faults (worn detents, broken actuator stems, melted housings, or loose mounting causing poor contact). Practical diagnostics include verifying continuity between the common and the energized terminal only when the knob is depressed, checking for presence of the range mains supply at the switch input with the control engaged, and performing a wiggle test on the harness and connector while observing ignition behavior. For example, no audible click and no continuity with a multimeter when the knob is pressed points to a failed switch, whereas consistent clicks with no spark suggest electrode/grounding or spark module issues; visible carbon tracking, pitted contacts, or discolored plastic indicate electrical stress that warrants replacement.
- No spark and no click: switch fails open or harness connector broken.
- Intermittent spark: high contact resistance or loose terminal/wire.
- Continuous sparking when not commanded: stuck contact or short to chassis ground.
- Physical play or stuck knob: mechanical wear or broken actuator/return spring.
| Item | Description |
|---|---|
| Continuity behavior | Closed (low resistance) only with knob actuated; open (infinite) at rest. |
| Mains supply check | verify presence of supply voltage at the switch input when the control is on; absence indicates upstream power or harness fault. |
| Mechanical condition | Inspect for cracked housing, worn detents, or a non-returning shaft that can prevent reliable switching. |
| Connector integrity | Check for corrosion, bent pins, or broken wires in the harness that cause intermittent or lost connection. |
Compatibility by Appliance Model, Replacement Considerations, and Step-by-Step Installation Guidance
The 316580615 Frigidaire range Spark Ignition Switches with Wire Harness is a combined electromechanical assembly that routes mains power from the control knob to the spark generator and provides auxiliary contacts for the gas valve interlock. Functionally the switch supplies momentary high-current to the ignition module while providing position sensing for the control knobs; compatibility therefore depends on the physical mounting footprint,connector pinout,and harness length as much as on the part number. Technicians should compare the terminal layout, wire color mapping, and bracket orientation on the replacement assembly to the original component in the range before installation to ensure correct sequencing of spark and gas valve activation.
Replacement decisions should consider operating voltage (typically 110-120 VAC), connector type (male/female spade or multi-pin plug), and the condition of harness insulation and strain relief; common failure modes are open contacts (no spark), pitted/carbonized contacts (continuous arcing), or intermittent operation caused by worn detents or loose connectors. Use a multimeter to check continuity across switch positions and visually inspect for carbon tracking or melted insulation before and after replacement. The unordered list below provides a concise, practical installation sequence and the reference table summarizes key technical attributes to verify compatibility.
- Disconnect power and gas supply.
- Remove access panels and photograph wiring and connector orientations for reference.
- Label wires or connectors, then unplug the harness from the old switch assembly.
- Measure continuity/resistance across switch contacts in each knob position to document failure mode.
- Remove mounting screws, transfer or replace any mounting bracket, and install the new switch/harness assembly in the correct orientation.
- Reconnect the harness, secure ground(s), restore power, and verify switch operation visually with the gas supply closed; perform final tests with gas restored and check for leaks after confirming correct ignition sequencing.

Q&A
What is the Frigidaire part 316580615 and what does a ”spark ignition switch with wire harness” include?
Part 316580615 is an OEM replacement ignition switch assembly for Frigidaire ranges. It normally includes the ignition switch(es) used to call the spark module and a pre-wired harness that connects those switches to the range wiring and spark module. The assembly replaces worn or damaged switch contacts and the attached wiring for a plug‑and‑play replacement that matches the original connectors and mounting points.
How do I know if 316580615 is compatible with my Frigidaire or Kenmore range?
Check your appliance model number (usually on a tag behind the oven door,storage drawer,or on the back) and compare it to the part’s compatibility list on the parts seller or the manufacturer’s parts diagram.Also verify that the connector types and number of switch positions on the replacement match your old switch assembly. If unsure, provide your range model to a parts dealer or Frigidaire support to confirm compatibility.
What symptoms indicate the ignition switch or harness is failing?
Common signs are: continuous clicking when a burner knob is pressed but no spark at the electrodes, intermittent sparking, burners that only ignite sporadically, visible burning or melting on the switch terminals or harness, or a knob that feels loose or has no detent.These symptoms can indicate worn switch contacts, broken wires, or corroded/melted connectors.
How can I test the ignition switch and harness safely?
Always disconnect power (unplug or switch off the breaker) and shut off the gas before opening the range. Visually inspect the harness for melted insulation or burned terminals. With a multimeter you can check continuity across the switch terminals while operating the control (with power off): the switch should show continuity (near 0 ohms) between its common and the burner terminal when urged to the “ignite” position. With power restored and appropriate safety precautions, you can measure that the switch is supplying 120 VAC feed to the spark module/output lead while the knob is depressed – if there is line voltage at the feed but no output when operated, the switch is faulty. Do not attempt to measure the high-voltage output of the spark module with a standard meter.
Can I replace this part myself and what tools do I need?
Yes – this is a doable DIY job for someone pleasant with basic appliance repairs. Tools typically needed: flat/Phillips screwdrivers, nut drivers, needle-nose pliers, and a multimeter for testing. Turn off power and gas, remove the control panel or back panel to access the switch, unplug the old harness from the module and controls, transfer or remove mounting hardware, connect the new harness making sure connectors are fully seated, then reassemble and test. Allow 30-60 minutes depending on access and experience.
What wiring/connectors does the harness use and how should I hook it up?
The replacement harness uses the same style of factory connectors as the original (typically standard insulated female spade terminals on 1/4″ connectors). Hookup is done by matching the harness leads to the corresponding terminals on the spark module and switches (match colors/terminal labels or the original harness layout). Do not swap burner outputs; follow the wiring diagram on the range or photograph the original harness before removal to ensure correct reconnection.
My range clicks but still won’t light - how can I tell if the switch,harness,spark module,or electrode is at fault?
Start with visual checks: cracked or carbon-tracked electrodes and poor ground are common causes. With a helper, observe whether the spark module is clicking and whether sparks appear at the electrode. If the module clicks but there is no voltage from the switch to the module, suspect the switch/harness. If the switch sends 120 VAC to the module but there is no spark at the electrode, suspect the spark module or the electrode/grounding.Use a multimeter to confirm switch continuity and presence of line voltage at the module input when the knob is pressed. Replace the failed component based on those tests.
Any installation tips or common pitfalls to avoid?
Always disconnect power and gas frist. Photograph or label wiring before removal so you can reconnect correctly. Inspect connectors for burning or looseness and replace the entire harness if insulation is damaged. Make sure all spade connectors are fully seated and that the electrode wires are solidly grounded to the range chassis. Test operation before fully reassembling the range.If you’re unsure after testing, consult a licensed appliance technician – incorrect wiring can prevent ignition or create safety hazards.
