316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch is an electrical assembly used on Frigidaire ranges and cooktops that combines a wiring harness and an integrated ignitor switch; it is a discrete interconnect component that routes power and control signals between the user controls, ignitor electrodes, and associated burner circuits. The assembly typically consists of multi-conductor wiring with factory crimped terminals or plugs, heat- and abrasion-resistant insulation, and a mechanical switch or switch interface designed to actuate the spark ignitor when a burner control is turned on.
Within the appliance, this wiring harness and ignitor switch serve as the electrical pathway and switching mechanism that enables spark ignition of gas burners and coordinates that function with the range’s control system. It interfaces with the cooktop burner modules or electrodes, the control knobs or infinite switches, the main power supply, and in some designs the range control board; proper connector seating, wire continuity and insulation integrity are required so that ignition pulses are delivered reliably while maintaining grounding and separation from high-heat surfaces. Because it carries mains-level voltage and is located near heat sources, the harness also plays a role in electrical safety and in preventing false or intermittent ignition events caused by damaged wiring or poor connections.
In this article readers will find a technical overview of the part’s function and construction, guidance on compatibility and how to confirm the correct part number for a given Frigidaire model, common failure symptoms to watch for (such as no spark, intermittent ignition, visible heat or arcing damage, or loss of continuity), and practical troubleshooting and replacement considerations. The discussion will cover diagnostic checks a technician or experienced appliance owner can use to isolate harness-related faults, considerations for connector types and routing during replacement, and safety precautions relevant to working with mains power and gas ignition systems.

Function and Role of the Wiring Harness and Ignitor Switch in Range Ignition and safety circuits
The 316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch is an integrated assembly that routes power and control signals between the range control board, spark/ignition module, gas valve, and safety sensors. In operation the harness carries line and neutral conductors, ground, and discrete control leads to the ignitor switch and spark electrodes; the ignitor switch provides the switching connection for the high-voltage spark generator while also integrating with the range’s safety interlocks (door switches, thermal limits, and flame-sensing circuits). As the assembly includes matched connectors, wire lengths, and color-coded leads, using the correct harness preserves the original pinout and simplifies service on compatible Frigidaire models without requiring splicing or rewiring of safety circuits.
During a normal ignition event the control board applies power through the harness to the ignitor switch, the switch actuates the spark transformer and high-voltage pulses are delivered to the electrode until the flame is detected and the gas valve latch is engaged via flame-sensing or thermocouple feedback. Typical failure modes include open or high-resistance conductors, burned or deformed terminals, intermittent contacts that cause loss of spark, or a stuck switch that produces continuous sparking; such faults can prevent ignition, cause repeated sparking, or defeat flame-detection logic. Technicians diagnose these issues with continuity checks, voltage measurements at the harness connector (such as ~120 VAC presence during a burner call), and inspection for heat or corrosion; when replacing the assembly, match the OEM 316219004 part number, connector types, and wire gauge to maintain correct behaviour and safety. Do not bypass safety interlocks or flame-sensing circuits during troubleshooting or repair.
- Common symptoms: no spark, continuous sparking, intermittent ignition, visible terminal damage or melting.
- key features: matched OEM connectors, integrated ignitor switch, heat-rated insulation, color-coded leads for correct pinout.
- Basic checks: continuity of leads, voltage present during ignition call, visual inspection for heat damage or corrosion.

How the 316219004 Frigidaire Stove Oven range Cooktop Wiring Harness with Ignitor Switch Interfaces with Valves, Ignitors, and Control Boards
The 316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch provides the physical and electrical interface between burner controls, spark ignitors, gas safety valves, and the appliance control board. The harness routes both switched line and control-level signals, and the integrated ignitor switch closes the ignition circuit when a burner knob is actuated so the control board or spark module can deliver spark pulses to the ignitor and permit the valve solenoid to see its supply. Connectors are typically keyed and color-coded to match Frigidaire pinouts; correct mating and continuity are required for reliable spark timing and valve sequencing, so incompatibilities or reversed pinouts will cause either no ignition, continuous energizing of a valve, or intermittent operation.
From a service perspective the harness is passive wiring and switch elements rather than a logic device: faults are normally open/shorted conductors, corroded pins, or failed switch contacts. Technicians troubleshoot by verifying continuity across the switch when the control is operated, checking for proper line voltage at the harness terminals for the valve and ignitor circuit, and inspecting insulation and connector integrity. When replacing the assembly, match the connector count, pin assignment, and wire color codes to the appliance wiring diagram; swapping a harness with a different layout can leave valves or ignitors without a neutral return or tie signals together, creating unsafe or nonfunctional behavior.
- Key features: integrated switch contacts, keyed connectors, color-coded wires for pinout verification.
- Common symptoms of failure: no spark, continuous valve actuation without ignition, intermittent ignition or arcing at connectors.
- Typical service checks: continuity under actuation, presence of supply voltage at terminals, visual inspection of connector pins.

Common Failure symptoms: Electrical, Mechanical, and Intermittent Ignition Fault Indicators
316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch is a combined electrical harness and user-actuated switch assembly that routes control voltage from the range control and spark module to the cooktop ignitor electrodes.Its primary function is to provide low-resistance, correctly phased connections and a reliable mechanical contact when the surface control knob or integrated switch is operated. failure modes that affect function can be purely electrical (open conductors, short to ground, or high contact resistance), mechanical (worn switch actuator, broken lugs, or misaligned mounting), or intermittent (vibration-induced opens, thermal expansion at a corroded terminal).Compatibility issues typically arise from differences in connector type, wire length, or pinout orientation, so replacement parts must match the original harness pin configuration and terminal style to avoid misrouting voltage to other components.
Technically, electrical symptoms are diagnosed by verifying continuity and applied voltage at the harness during an ignition attempt: a closed switch should show near-zero ohms across its contacts and the module should present the expected mains-level pulse (commonly in the 110-125 VAC range on North American units) to the ignitor electrode. Mechanical indications include a tactile or visible loss of actuator spring force, bent or fatigued terminals, and heat-damaged insulation that can produce arcing at connectors. Practical troubleshooting steps include wiggling the harness under load to reproduce intermittent faults, inspecting for discoloration or melting at crimp points, and measuring resistance across the switch both cold and after several cycles to reveal contact degradation; these checks help distinguish a faulty harness/switch from a failed spark module or electrode.

Replacement Considerations, Model Compatibility, and Step‑by‑Step Installation Best Practices
The 316219004 Frigidaire Stove Oven Range Cooktop wiring Harness with Ignitor Switch connects the cooktop ignitor circuit, switch contacts, and ground paths into a single assembly to ensure reliable sparking and control feedback. This harness bundles the ignition switch that closes the circuit to the spark module with the color‑coded leads and fast‑disconnect terminals used on many Frigidaire ranges; technicians should match the harness terminal count, terminal type (spade/quick disconnect), and lead colors to the appliance wiring diagram on the model tag. Compatibility depends on mechanical routing, connector geometry, and electrical ratings of the ignitor switch and wires – verify the OEM part number and measure continuity and switch resistance before installation to confirm the replacement will behave identically under load and during repeated cycling of the burner controls.
- Verify model and part cross‑reference from the range model tag and service manual, not only the visible connector shape.
- Disconnect power (and gas supply for gas ranges) and discharge any stored energy before accessing the harness.
- Document or photograph original wire routing, terminal positions, and grounding locations to replicate shielding and strain relief.
- Check continuity of the ignitor switch and insulation integrity of leads; replace if any high resistance, intermittent contact, or brittle insulation is found.
- Use proper tools: multimeter, insulated nut drivers, crimpers, and heat shrink or high‑temperature wire sleeves for repairs.
During installation, route the harness to avoid heat sources and sharp edges, secure it with existing clips or equivalent fasteners, and ensure the ignitor switch actuator engages smoothly with the control knob mechanism; an improperly seated switch can produce intermittent sparks or continuous firing. After physical installation, perform functional checks: verify switch continuity in each knob position, confirm proper spark timing and ground reference at the ignitor, and observe several ignition cycles under normal operating conditions to detect arcing or intermittent contacts. If any terminal sizes, wire gauges, or switch ratings differ from the original, repair using equivalent temperature‑rated components rather than forcing mismatched connectors, and update the service record with the replacement part number and test results.

| Tools Recommended | Multimeter, insulated nut drivers, crimpers, heat shrink, heat gun |
Q&A
What appliances is the 316219004 Frigidaire wiring harness with ignitor switch compatible with?
The 316219004 is an OEM frigidaire replacement part designed for specific Frigidaire/Gladiator/White-Westinghouse ranges and cooktops that use the same harness and ignitor switch assembly. Compatibility is determined by the appliance model number (usually found on the range’s frame or behind a drawer). Always verify the part number against your appliance model number in the manufacturer’s parts list or with the parts vendor before ordering.
What are the common symptoms that indicate the harness or ignitor switch has failed?
Common symptoms include surface burners or oven burners clicking continuously with no spark, intermittent ignition, one or more burners failing to light, visible damage to the wiring or connectors (charring, melting, corrosion), or the appliance not responding when the control is operated. If the burner igniter never sparks or the module does not receive continuity from the switch, the harness or switch may be faulty.
How do I safely test the ignitor switch and wiring harness?
First, disconnect power to the range at the breaker and, for gas ranges, turn off the gas supply. Visually inspect the harness for burns, breaks, or loose connectors. Use a multimeter set to continuity or resistance: check for continuity through the switch when it is actuated (refer to service manual for correct switch actuation method) and verify there are no open circuits in the harness. For glow-type ignitors (oven), measure resistance across the ignitor element; if it’s open (infinite resistance) the ignitor is bad. If you’re unsure about which terminals to test, consult the appliance wiring diagram or hire a technician.
What tools and parts do I need to replace the 316219004 harness and how do I install it?
Typical tools: nut drivers/screwdrivers, needle-nose pliers, wire cutters, electrical tape / heat-shrink, and a multimeter. Replacement parts: the OEM 316219004 harness assembly and any mounting clips or screws that came with it. Installation steps (high level): 1) disconnect power and gas,2) access the harness by removing back panel or cooktop,3) photograph/label all connector locations,4) disconnect old harness and remove,5) route new harness in same path,connect all plugs securely (do not mix connector positions),6) fasten and secure away from heat/ moving parts,7) restore power and test burners. If connectors on the new harness do not match exactly, do not force changes-confirm you have the correct part.
Are wire colors and connector types standardized or do they vary for this part?
Wire colors and connector types are generally consistent for a given OEM harness but can vary between appliance models and years. The 316219004 harness will use the connector types required by the corresponding Frigidaire models; however you should rely on connector shape and the appliance wiring diagram rather than color alone when making connections. Always label or photograph connections before removal to ensure accurate reconnection.
Can I repair or splice the existing harness instead of replacing it?
Minor repairs (replacing a short length of damaged wire and using proper splices/crimps, heat-shrink insulation, and strain relief) can be acceptable for someone experienced with appliance wiring, provided the repair restores mechanical integrity and insulation and the splices are in an area protected from heat and moisture. However, because ignition circuits carry high voltages (spark systems) and are safety-critical, OEM replacement of the entire harness is recommended for reliability and safety. avoid unreliable tape-only repairs.
How do I test the ignitor switch function specifically without replacing the entire harness?
With power off,disconnect the switch connector and use a multimeter to test continuity across the switch terminals while actuating it (or recreating the mechanical condition that closes the switch). If the switch does not change state when actuated,it is indeed faulty. For spark systems you can also check if the switch is sending the correct signal to the spark module when the control is turned on (requires following the wiring diagram and testing with the range powered on briefly-only for qualified personnel due to shock risk). If uncertain, have a trained technician perform live tests.
Where can I get a genuine 316219004 harness and will it come with a warranty?
Genuine 316219004 harnesses are available from Frigidaire authorized parts dealers, appliance parts stores, and reputable online retailers. Purchasing from OEM dealers ensures authenticity.Warranty coverage varies by seller: many OEM parts come with a limited warranty (often 30-365 days) that covers defects but not installation labor. Check the vendor’s warranty and return policy before purchase. If in doubt,contact Frigidaire customer support with your appliance model number for guidance.
