316219004 Frigidaire stove Oven Range cooktop wiring Harness wiht Ignitor Switch is an electrical assembly used in Frigidaire ranges that combines insulated conductors, connector terminals, and an integrated ignitor switch to support the appliance ignition circuit. The component is a wiring harness – a preconfigured bundle of wires and connectors – that includes the switch mechanism used to initiate or signal the spark/ignition sequence; it is intended to fit the factory routing and connector patterns used in compatible cooktop and range control modules.
Inside the appliance, the harness routes power and control signals between the user control (knob or front panel), the spark or ignition module, individual burner igniters or the oven igniter, and, in gas models, the gas valve interlock and associated control board inputs. The ignitor switch portion provides the mechanical/electrical input that either completes the ignition circuit or sends a signal to the ignition module, while the harness conductors carry low-voltage control signals and, where applicable, high-voltage pulses to the igniters. Because it interfaces with the ignition module, gas valve, grounding system and front controls, correct connector orientation, insulation integrity and heat-resistant routing are vital for reliable operation and safety.
In the article that follows, readers can expect a detailed look at the part’s function and electrical role, guidance on model compatibility and identification, common failure symptoms (for example, no spark, intermittent ignition, arcing, or visible connector damage), and diagnostic approaches such as visual inspection and basic electrical checks. The article will also cover practical replacement considerations - selecting the correct part number, verifying connector and wire lengths, routing and securing the harness to avoid heat or abrasion, and general safety reminders to isolate power and gas before servicing – to help technicians, engineers, and appliance owners assess, troubleshoot, and plan repairs.

Function and Role of the Ignitor Switch Wiring Harness in Frigidaire Stove/Oven Range Operation
The 316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch is the electrical assembly that routes control signals, supply voltage, and return/ground paths between the user controls, the ignition module, and the burner or oven ignitor. Functionally, the harness includes the momentary switch contacts used to trigger the ignition module, insulated conductors sized to the original equipment specifications, and factory-style connectors and mounting clips that maintain correct signal timing and electrical continuity. In practice this means the harness does not generate the high-voltage spark itself but provides the switching and grounding interface the spark module requires, so connector type, wire gauge, and correct routing are critical for reliable ignition and for avoiding heat- or vibration-induced failures.
- Primary role: route control command and complete the ignition circuit between switch, module, and ignitor.
- Common failure symptoms: no spark,intermittent ignition,visible charring at connectors,or ignition only when wires are manipulated.
- Diagnostic checks: continuity of switch contacts, insulation integrity, and proper seating of OEM-style connectors against the control and module pins.
Technicians should confirm model compatibility and terminal mapping before replacement; the harness is designed to match original connector shapes and wire color codes so that timing and safety interlocks behave as designed. When replacing the part, remove power, document each connector position, preserve mounting hardware and routing paths to prevent heat exposure or abrasion, then verify ignition behavior with the stove powered and controls operated; if intermittent operation persists, test the ignition module and gas valve separately to isolate the fault.The table below summarizes the critical technical references for field service.

How the 316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch Interfaces with Control Circuits, Ignition Modules, and Gas Valves
The 316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch is the molded interconnect that ties the user controls, the ignition module, and the gas valve solenoids into a coordinated ignition sequence.The harness carries both line-level feeds and lower-voltage control/trigger signals, provides keyed connectors and color-coded conductors for proper routing, and incorporates the mechanical switch used by the knob to initiate a spark. In many Frigidaire ranges the knob closure routes mains power (commonly the appliance line, typically around 120 VAC in North American models) to the ignition module while simultaneously providing a control feed to the valve circuit so that spark generation and gas flow occur in the correct order.
Functionally,the harness isolates and routes distinct circuits so the control board,ignition module,and gas valves do not conflict electrically; the ignition module receives a trigger from the harness and produces the high-voltage pulses to the electrode leads,whereas the valve solenoids receive switched line or control power to open. For troubleshooting and compatibility checks, technicians should verify connector pin continuity and the presence of expected line/control voltages at the harness connectors, inspect insulation and splice integrity, and compare pinouts to the reference below. Typical symptoms of a harness fault are intermittent or absent spark, valves that do not energize even when the knob is turned, or visible heat damage at connector housings; replacing the harness restores correct electrical routing when the module and valves themselves are known good.
- Key interface points: control board trigger, ignition module feed, ignitor switch contact, gas valve solenoid feed, and chassis ground.
- Common checks: continuity of switch contacts, line voltage presence, connector seating and wire insulation condition.
- Compatibility: OEM connectors and wire lengths are matched to specific Frigidaire range models-confirm 316219004 fitment against model pinouts.

Common Failure Symptoms: Electrical and Mechanical Indicators of a Faulty Wiring Harness or Ignitor Switch
The 316219004 Frigidaire Stove Oven range Cooktop Wiring Harness with Ignitor Switch routes power and control signals between the range’s control board, surface elements, and the ignitor/switch assembly. The harness contains multiple insulated conductors, connector housings keyed to specific terminals, and a mechanical/electrical switch that closes the ignitor circuit when a control is actuated.Failure modes are electrical (open conductors, shorted wires, high-resistance contacts) and mechanical (worn switch contacts, melted housings, broken terminal clips). Compatibility depends on matching connector type,pin count,wire lengths,and the switch actuation style; using a mismatched harness can cause intermittent contact,incorrect element switching,or unsafe heating behavior in a Frigidaire range.
- no spark or no heating: open circuit in ignitor circuit or failed switch contact preventing current flow.
- Intermittent heating or sporadic element operation: high-resistance joints,partially broken conductor strands,or loose connector pins.
- continuous sparking or stuck element: contacts welded closed or short to chassis ground causing constant energization.
- Visible damage (melting, charring, corrosion): thermal degradation of insulation or oxidized terminals increasing resistance and heat.
- breaker trips or blown fuses when a function is selected: short to ground within harness or switch.
Disconnect power before testing. For diagnostics, verify continuity through the harness and across the switch with a multimeter, inspect connector pin seating and insulation integrity, and verify line voltages at harness input under load. A practical test: observe whether applying the control closes the switch terminals and supplies expected voltage to the ignitor or element; if voltage appears but the element does not draw current,suspect an open conductor or poor terminal contact. When ordering replacements,match the 316219004 harness by connector profile and terminal wiring diagram rather than only model name-measure wire lengths,note color coding,and confirm the switch mechanism to ensure full compatibility and reliable restoration of function.

Replacement Considerations, Model Compatibility, and Step-by-Step Installation Procedure for the wiring Harness
The 316219004 Frigidaire Stove Oven Range Cooktop Wiring Harness with Ignitor Switch serves as the electrical backbone between the user controls, the ignitor circuit, and the heating elements or spark modules. It contains routed conductors, heat-resistant insulation, and a molded or crimped ignitor switch assembly that either routes mains power to an ignitor or provides a switching contact for a spark generator.Technically, the harness must present the correct connector types, pin count, wire gauge, and routing to interface with the oven control and ignitor; mismatched connectors or undersized conductors can cause high resistance, intermittent ignition, or thermal degradation. Inspect the 316219004 harness for secure crimp joints, intact insulation near heat sources, and the correct connector geometry against the appliance’s service diagram before replacement to ensure compatibility and safe operation.
Disconnect power before beginning work and follow the appliance manufacturer’s service instructions. typical installation involves removing access panels, documenting existing wire routing and connector orientations (photographing is recommended), detaching the old harness and transferring any clips or heat shields, and installing the new harness so that all terminal connections are fully seated and strain-relieved away from hot components. After reassembly, verify continuity on the ignitor circuit with a multimeter and perform an operational test: observe the ignitor behavior (spark pulses or glow element current), confirm control switch operation, and check for shorts or excessive voltage drop. If ignition does not occur, re-check connector seating, measure ignitor resistance against specification, and inspect the ignitor switch contact for wear before replacing additional components.
- Power off and tag the appliance circuit before starting.
- Document wire routing and connector orientation (photos recommended).
- Transfer mounting clips/heat shields and ensure wires are routed away from hot surfaces.
- Verify connections with a multimeter and perform an ignition functional test after installation.
