The 316536610 Frigidaire Ignitor/Orifice assembly is a combined ignition and gas‑metering component found in Frigidaire gas cooking appliances; it pairs an ignitor (either a spark electrode or a hot‑surface element, depending on the model) with a precisely sized orifice that meters gas flow to a burner port. As a single replaceable assembly, it locates the ignition source immediately adjacent to the gas jet and provides the mechanical mounting and sealing required to deliver gas from the manifold to the combustion zone.
functionally, the assembly interfaces with the appliance gas valve/manifold, the electronic ignition module or control board, and the flame‑sensing/safety devices. The orifice establishes the volumetric flow rate and pressure drop for the burner, determining flame shape and heat output, while the ignitor initiates combustion and, when paired with a flame sensor, allows the control system to confirm sustained ignition. Proper operation therefore depends on correct orifice sizing for the appliance’s fuel type (natural gas vs.LP), correct electrode positioning and gap, intact sealing against leaks, and reliable electrical connection to the ignition circuitry.
In this article you will learn how the 316536610 assembly functions, how to verify compatibility with specific Frigidaire models and fuel types, common failure symptoms (no ignition, delayed ignition, weak/unstable flame, or gas odor), logical troubleshooting checks (visual inspection, continuity and voltage checks, orifice obstruction assessment), and practical replacement considerations (correct orifice selection, mounting orientation, sealing and leak testing, and safe handling of ignition components). The emphasis will be on diagnosing issues that affect safe and reliable appliance operation and on the key technical details a technician or informed owner needs to plan a repair or replacement.

Function and Operational Role of the Ignitor/Orifice in Burner Ignition and Gas Flow Regulation
The 316536610 Frigidaire Ignitor/Orifice Assembly integrates a combustion ignitor and a precision orifice into a single mounting that locates thes components at the burner throat. the ignitor provides the ignition energy – either a spark or a hot-surface heat source depending on model design – while the machined orifice limits gas flow to a calibrated jet size so the fuel/air mixture reaches the correct volumetric flow and velocity at the burner ports. Correct alignment of the ignitor relative to the orifice and burner ports is critical: misalignment changes flame propagation characteristics and can produce incomplete combustion or delayed ignition.
During operation the ignitor must present the proper electrical characteristics and timing to reliably initiate combustion,and the orifice must match the appliance’s manifold pressure and fuel type (natural gas versus LP) to regulate flow. Common functional effects from component issues include weak or inconsistent flames, delayed ignition or continuous sparking, and odor or soot indicating rich combustion; conversely, an oversized orifice can produce a noisy, unstable flame and higher heat output than the design permits. Technicians should verify electrical continuity and voltage at the ignitor, inspect the orifice for debris or corrosion, and confirm the replacement assembly matches the original part number and orifice specification to maintain safe, predictable burner behavior.
- Function: Ignition source and flow metering combined for correct flame initiation.
- Compatibility: Must match manifold pressure, fuel type, and physical mounting.
- Symptoms of failure: delayed ignition, continuous sparking, weak flame, soot, or gas odor.

How the 316536610 Frigidaire Ignitor/Orifice Assembly Interfaces with the Gas Valve,thermostat,and Electronic Control Module
The 316536610 Frigidaire Ignitor/Orifice Assembly combines a high-temperature ignitor element with a matched orifice to both initiate combustion and accurately meter fuel flow to the burner. In operation the oven’s electronic control module applies line voltage to the ignitor; as the ignitor heats and its electrical characteristics change, either the control module or the gas valve’s internal sensing circuit recognizes the current draw and permits the gas valve to open. The thermostat or user-set temperature control (mechanical or electronic) provides the setpoint to the control module, which sequences power to the ignitor and gas valve; the orifice size on the assembly ensures the burner receives the correct volumetric flow for the appliance’s rated gas type (natural gas or LP), so mismatched orifice sizing will affect flame shape, heat output, and safe valve operation.
Technicians should consider both electrical and hydraulic compatibility when installing or troubleshooting the 316536610 frigidaire Ignitor/Orifice Assembly: verify the ignitor’s continuity and glow behavior under applied voltage, confirm the orifice is the correct drill size for the gas type, and ensure the module is sending the expected control signals before assuming valve failure.Practical symptoms that point to this assembly include a glowing ignitor with no gas flow (valve or signal fault), a weak or slow-glowing ignitor that fails to open the valve (ignitor degradation), or irregular flame due to incorrect orifice choice. When replacing the assembly, match connector type, mounting orientation, and orifice specification to the appliance model to maintain proper sequencing between ignitor, gas valve, thermostat input, and the electronic control module.
- Typical interface behaviors: ignitor heats → current draw monitored → gas valve opens when threshold met.
- Common diagnostic signs: ignitor glows but no flame, weak glow with delayed ignition, or uneven flame after replacement.
- Compatibility checks: electrical connector, orifice drill size, gas type (natural vs LP), and physical mounting alignment.

Common Failure Modes and Observable Symptoms: Misignition, Delayed Lighting, and Flame Instability
The 316536610 Frigidaire Ignitor/Orifice Assembly combines the ignition electrode or hot surface element with a precisely sized gas orifice to initiate and meter combustion for a burner. In normal operation the ignitor provides the energy to ignite the gas delivered through the orifice,and the orifice diameter determines flow rate and mixture strength; mismatch between the orifice size and the appliance’s design (or using the wrong fuel type) changes the flame shape and stability. Technicians should verify that the assembly is the correct OEM part for the model and fuel (natural gas vs. LP) because identical-looking assemblies with diffrent orifice sizes or electrode geometries will produce different ignition behavior and can cause persistent lighting problems even if the mechanical fit is correct.
Failure modes typically separate into defects in ignition energy (weak or intermittent spark/heat), restricted or inconsistent gas flow through the orifice, and sensor/alignment problems that prevent reliable ignition. Observable symptoms include delayed lighting, repeated misignition (clicking or sparking without sustained flame), weak or lifting flames, and intermittent flameout under load; these symptoms often coexist and point to combinations of electrode wear, carbon deposits in the orifice, incorrect orifice size, loose mounting, or abnormal supply pressure. Practical troubleshooting steps include visual inspection for carbon/soot, checking electrode gap and alignment, verifying orifice cleanliness and size markings, and confirming inlet gas pressure; replacing the assembly with a correctly specified 316536610 part resolves many issues caused by combined ignitor/orifice wear or contamination.
- Delayed lighting: ignition energy present but flame appears after a pause.
- Misignition: repeated sparking or clicking without a sustained flame.
- Flame instability: yellow, lifting, or oscillating flame indicating flow or mixture problems.
- Intermittent operation: normal performance alternates with failures, suggesting loose connection or partial blockage.
| Item | Description |
|---|---|
| Ignitor weak/failed | Reduced ignition energy causes repeated sparking or delayed light. |
| Clogged orifice | Restricted flow lowers flame stability and can cause yellowing or delayed combustion. |
| Incorrect orifice size | Mismatched to fuel type or burner results in under- or over-fueling and unstable flame. |
| Electrode alignment | Misaligned electrode increases ignition distance, producing misignition or delays. |
Compatibility, Replacement Procedure, and Troubleshooting diagnostics including Fitment, Torque Specifications, Leak Testing, and Electrical Checks
The 316536610 Frigidaire Ignitor/Orifice Assembly integrates the ignition element and a matched gas orifice to control flame onset and burner flow. Functionally, the ignitor provides the energy necessary to ignite gas delivered through the orifice while the orifice determines fuel flow and burner characteristics for either natural gas or LP service. Compatibility is governed by the appliance model and fuel type: the correct orifice size and mounting orientation must match the range’s manifold pressure and burner port geometry to achieve stable flame shape and control.Technicians should verify model cross-reference data and confirm the assembly’s porting and terminal layout before installation to avoid improper mixing, delayed ignition, or soot formation caused by incorrect flow rates or misaligned ignitor position.
- common symptoms: no ignition, delayed ignition/popping, weak or lifting flame, or gas odor before ignition.
- Initial checks: visual fit and gasket integrity, correct orifice for fuel type, continuity and connector condition, and supply voltage at the ignitor connector.
- Functional tests: resistance/continuity test, live voltage test (with safety precautions), and a controlled leak test at fittings after installation.
| Item | Description |
|---|---|
| Mounting torque (typical) | Mounting screws: 7-12 in·lb (0.8-1.4 N·m); orifice/nut: 20-35 in·lb (2.3-4.0 N·m). Verify OEM spec for exact value. |
| typical manifold pressure | Natural gas: ~3.5-5.0 in WC; LP: ~8-11 in WC. Confirm with service data for the appliance. |
| Leak test | Use a manometer or soapy solution at all gas joints; maintain appliance shutoff valve closed except for test connections during pressure checks. |
During replacement, isolate gas and electrical supplies, note ignitor orientation and lead routing, then remove mounting hardware and the old assembly; replace sealing washers or gaskets and align the new assembly so the ignitor tip sits in the same relative position to the burner ports. After hand-starting fasteners, torque to the ranges above and tighten electrical connectors to ensure low-resistance contacts-measure continuity across the ignitor and compare to service specifications or baseline values from a known-good unit. For troubleshooting, verify supply voltage to the ignition circuit (observing safety procedures), inspect for shorted or broken ignitor elements, and use a manometer to confirm manifold pressure and an appropriate orifice for the fuel; perform a final operational test: multiple prosperous ignition cycles with stable flame and no detectable leaks before returning the appliance to service.
