316580611 Frigidaire Ignitors Harness is a dedicated wiring assembly used in Frigidaire gas cooking appliances to connect the ignitor element to the appliance’s control and safety circuitry. The harness typically comprises high-temperature-rated conductors, molded or crimped connector terminalsand insulation materials selected to withstand proximity to burners and oven cavities; its form factor and connector types are designed to mate with the ignitor, gas valveand control board used in specific Frigidaire models.
Within the appliance the ignitor harness functions as the electrical link that delivers operating current and signal continuity between the control electronics, the safety interlocks (such as flame sensing or thermal cutouts), the gas valveand the ignitor element itself. It therefore interacts directly with the ignition subsystem and indirectly with temperature control and safety subsystems: proper routing, secure connectionsand intact insulation are essential for reliable ignition, correct feedback to the controls, and avoidance of short circuits or heat-related failures.
This article explains the harness’s intended function, how to confirm compatibility with specific appliance models, common failure symptoms to recognize (for example failure to ignite, extended glow time, intermittent ignitionor diagnostic fault codes)and a systematic approach to troubleshooting including the electrical checks and visual inspections technicians commonly perform.It also covers replacement considerations such as matching connector types and lengths, heat protection and routing best practicesand points to verify when choosing a replacement part to restore safe, reliable operation.

Functional Role, Wiring Topologyand Electrical Specifications of the Ignitor Harness
The 316580611 Frigidaire ignitors Harness provides the physical and electrical link between the oven ignitors and the control/safety circuitry, delivering power while protecting conductors from the oven’s high-temperature environment. In most Frigidaire gas ranges the harness organizes two-conductor runs (separate bake and broil leads when applicable) and terminates in factory-fit fast-disconnect terminals that match the ignitor and control board mating points. The harness also frequently enough includes a grounding conductor or shield and durable insulation to prevent chafing and heat damage; correct connector type, lead lengthand terminal polarity are practical compatibility details a technician should verify when replacing the harness to ensure a plug‑and‑play fit with existing ignitors and valve controls.
- Features and checks: confirm terminal size and keying, verify adequate lead length and routing for strain relief, inspect insulation for heat aging or melting, and test for continuity or shorts before installation.
Electrically the harness carries the supply used by the ignitor during warm-up and ignition cycles-commonly supplied at household mains potential (typically 120 V AC in North American appliances)-and is sized so voltage drop is negligible across the run. Typical harness construction uses 16-18 AWG conductors with high-temperature silicone or PTFE-style insulation rated for oven chamber proximityand connectors sized to industry quick-disconnect standards. For troubleshooting, measure AC voltage at the harness connector during an ignition attempt to confirm control outputand use a continuity/resistance check to detect open conductors; a harness fault will show open or intermittent continuity while a failed ignitor will show a valid circuit but out-of-spec resistance. When replacing the harness,match connector types,conductor gauge,and temperature rating rather than relying solely on part appearance to maintain safe,reliable operation.

How the 316580611 Frigidaire Ignitors Harness Interfaces with the Control Board, Ignitorand Gas Valve
The 316580611 Frigidaire Ignitors Harness provides the physical and electrical link between the oven’s control board, the hot-surface ignitorand the gas valve, routing control signals and mains power while preserving the correct pinout and insulation ratings.In operation the control board sends mains voltage through the harness to the ignitor so it can heat; the board monitors the ignitor’s electrical behavior (current or resistance change) to determine when the ignitor is ready, and then energizes the gas valve coil through the same harness or a related circuit. The harness also carries the flame-sensing or ground return path used by the control logic to verify successful ignitionand its connectors are keyed to prevent incorrect mating with other harnesses or modules.
When evaluating compatibility or troubleshooting, confirm that replacement harnesses match the original in connector type, wire gaugeand insulation temperature rating to ensure safe operation with the control board and valve. Common practical checks include measuring continuity across the harness leads, verifying voltage at the harness connector while running the ignition sequenceand inspecting for brittle insulation or corroded terminals that can create intermittent connections; such as, an oven where the ignitor glows but the gas valve never opens frequently enough traces to a broken supply lead or a failed board output within the harness interface. use a harness with the same pinout and thermal spec as the OEM unit when replacing the part to avoid mismatched signaling or overload on the control board.
- Key features: keyed connectors, correct wire gauge, flame-sense/ground returnand high-temperature insulation.
- Typical failure modes: connector corrosion, broken conductorsand insulation degradation near heat sources.
- Diagnostic steps: visual inspection, continuity checksand measuring control board output at the harness under power.

Common failure Symptoms and Diagnostic Procedures for Ignitor Harness Faults
The 316580611 Frigidaire ignitors Harness serves as the electrical interconnect between the appliance control or relay and the oven ignitor assembly; it supplies the required live and neutral conductors and provides the mechanically compatible connector and heat-resistant insulation. Failures of the harness typically manifest as open circuits at the connector, increased resistance from corroded contactsor thermal damage to insulation and terminals. Compatibility is persistent by pin spacing, connector type, wire gauge, and temperature rating – using a harness with incorrect connectors or insufficient heat tolerance can produce intermittent operation or premature failure even if the ignitor itself is serviceable.
Diagnosing harness faults combines a visual inspection with targeted electrical tests.start with power removed and check for melted insulation, pin discolorationor loose crimped terminals; then measure continuity across the harness connector with a multimeter and note any high-resistance readings or open circuits. Reapply power only for a live-voltage check: observe supply voltage at the harness during the ignition sequence and compare behavior to expected ignitor current or voltage (if the ignitor shows proper resistance but no supply voltage appears, the control or relay is the likely fault). Wiggle-testing connectors while monitoring continuity or voltage can reveal intermittent breaks; if the harness shows arcing, burned terminalsor persistent high resistance, replace it with a part that matches the original mechanical and thermal specifications.
- No glow or no ignition while control cycles (possible open harness or poor connection)
- Intermittent ignition or delayed glow when tapping or wiggling the connector
- Visible heat damage, melted insulationor discolored pins at the connector
- Multimeter shows open circuit or significantly higher than expected resistance across harness leads
- Supply voltage present at control but absent at the ignitor connector during start sequence
| Item | Description |
|---|---|
| continuity expectation | Harness should show near-zero additional resistance; open or large increases in resistance indicate faults |
| Visual indicators | Discolored or melted insulation, pitted or blackened terminalsor loose crimps suggest replacement |
| Diagnostic priority | Isolate ignitor vs. harness: measure ignitor resistance (typically tens to a few hundred ohms) then verify harness continuity and voltage under load |
Compatibility,Replacement Considerations,and Step-by-Step Installation for the 316580611 Frigidaire Ignitors Harness
The 316580611 Frigidaire ignitors Harness is a short,thermally rated wiring assembly that provides the mechanical and electrical interface between a range or oven hot-surface ignitor and the appliance’s control circuitry. It typically uses insulated high-temperature conductors and polarized spade terminals to carry the ignitor connection while resisting heat exposure near the burner or bake element. When evaluating compatibility, compare terminal style (male/female spades), wire gauge and length, and the sleeve material rating; mismatched terminals or insufficient temperature rating can cause intermittent ignition, arcingor premature insulation failure.Technicians should also verify that the harness routing clears moving parts and maintains the original strain-relief geometry to prevent chafing or contact with the element.
| Item | Description |
|---|---|
| Connector type | Spade terminals (confirm male vs. female and 1/4″ vs. 3/16″ size) |
| Wire gauge | Usually 16-18 AWG high-temperature wire |
| Insulation rating | Heat-resistant sleeve rated for 200-300°C in proximity to ignitor |
| Typical use | Replacement harness for Frigidaire oven/range ignitors |
For replacement and installation, start by ensuring the range is de-energized and the circuit breaker is off, then remove the access panels to expose the ignitor assembly. Disconnect the old harness at both the ignitor and the control/thermostat,noting routing and any retained clips or grommets; replace like-for-like,keeping terminal orientation and polarity the same where applicable.Route the new harness away from direct flame paths and secure it with the original clips or equivalent heat-resistant fasteners; after reassembly, reapply power and confirm correct operation by observing the ignition cycle and measuring continuity across the harness and the ignitor (expected hot-surface ignitor resistance typically ranges from ~40-200 Ω depending on element design).Keep in mind that damaged connectors, compromised insulationor excessive harness length requiring splices should be corrected with proper high-temperature components rather than temporary fixes.
- Compatibility checklist: terminal size, wire gauge, insulation temperature rating, harness length, and retention hardware.
- Basic installation steps: power off, access ignitor, remove old harness, install matched harness, secure routing, test continuity and ignition.
- Troubleshooting: check for loose terminals, measured resistance outside expected rangeand signs of heat damage or arcing.
Q&A
What is the 316580611 frigidaire ignitor harness?
The 316580611 is a replacement wiring harness made for certain Frigidaire gas ranges/ovens. It provides the electrical connection between the oven ignitor (hot surface igniter) and the oven’s control/gas valve wiring, including insulation, connectors and any mounting grommets needed to route the wiring safely inside the oven cavity.
How do I know if the harness is the cause of my oven not lighting?
Common signs of a failing harness include visible chafing, melted or burnt insulation, loose or corroded connector pins, intermittent ignition or complete loss of ignition while the ignitor itself looks intact. To confirm, visually inspect the harness, check continuity with a multimeter, and verify the ignitor is receiving voltage when the oven calls for heat. If the harness shows damage or has no continuity/voltage where expected, it should be replaced.
Can I replace the harness myself and what tools are required?
Yes,a competent DIYer or technician can replace the harness. Required tools typically include a screwdriver or nut driver set, needle-nose pliers, wire tiesand a multimeter for testing. Always turn off electrical power to the appliance (and gas if you will be disconnecting gas components) before starting. Follow the oven’s disassembly instructions to reach the ignitor assembly, unplug the old harness, route and secure the new harness, and reconnect all terminals.
How do I test the ignitor and harness before replacing parts?
With power off, use a multimeter to check continuity through the harness; an open circuit indicates a bad harness. With power restored and the oven calling for heat (only if you’re qualified), confirm the ignitor receives the expected line voltage (commonly ~120 VAC on domestic ovens). You can also check the ignitor element resistance per the service manual; many hot surface ignitors show low resistance (tens of ohms) while a completely open element is failed. If the harness passes but the ignitor shows no voltage or is open, replace the ignitor instead.
Is the 316580611 an OEM part and will it fit my Frigidaire model?
316580611 is an OEM Frigidaire part used on specific models. Fitment depends on your exact appliance model number – not all Frigidaire ovens use the same harness. Always verify compatibility with your model number via the Frigidaire parts site, the appliance’s parts diagramor an authorized parts dealer before purchasing.
What safety precautions should I follow when replacing the harness?
Turn off electrical power to the appliance at the breaker and, if applicable, shut off the gas supply. Allow the oven to cool completely. wear insulated gloves and eye protection. Avoid working on live circuits; if you must test live voltages, only do so with proper training and insulated tools. Ensure wires are routed away from sharp edges and high-heat surfaces and secure all connections to prevent arcing or future damage.
How long does replacing the 316580611 harness usually take and what is the expected cost?
Installation time typically ranges from 15 to 45 minutes depending on access and your experience. The harness part itself usually costs modestly (often in the low tens to low hundreds of dollars depending on seller and whether it’s OEM), but prices vary-check Frigidaire parts retailers and reputable online stores. If you hire a technician, add labor costs.
after replacing the harness the oven still won’t light-what should I check next?
If the new harness is installed correctly and the oven still won’t light,check the ignitor element,the gas valve,and the control board. Test the ignitor for proper resistance/operation and confirm it draws the required current to open the gas valve (this test should be done by a qualified technician). Also inspect gas supply and any safety switches or error codes. If uncertain, contact a qualified appliance technician to diagnose high-voltage or gas-related failures safely.
