316237704 Frigidaire Ignitor/Orifice Assembly is a combined ignition and gas metering component designed for use in Frigidaire gas cooking appliances. The assembly typically integrates an ignitor element-either a spark or hot-surface type depending on the model-with a precision-machined orifice that meters gas flow to the burner; together these parts control the initiation and initial fuel delivery for a single burner or group of burners.
Inside the appliance the ignitor/orifice assembly interfaces directly with the gas manifold and valve, the appliance control/ignition module, the burner head and associated flame sensing or thermocouple circuitry. Its function is to provide reliable ignition energy at the correct timing while the orifice establishes the expected volumetric gas flow at the prescribed pressure; correct operation affects flame stability, combustion quality and the interaction of safety interlocks such as the flame sensor and gas shutoff valve.
In the article that follows you will find a technical description of the assembly’s function and construction, guidance on model compatibility and orifice sizing (including natural gas vs LP considerations), common failure symptoms to recognize (no ignition, delayed ignition, poor flame shape, gas odor), systematic troubleshooting checks (electrical continuity, ignitor resistance, orifice blockage inspection, gas pressure considerations) and practical replacement considerations such as correct part selection, sealing and torque practices, and safety precautions to observe during service.

Function and Thermal/Ignition Role of the Ignitor/Orifice Assembly in Frigidaire gas Burners
The 316237704 Frigidaire Ignitor/Orifice Assembly integrates the gas metering orifice with the ignition element to control both the fuel flow and the thermal energy required to start combustion. The orifice is a precision restriction sized for a specific burner rating and gas type (natural or LP), while the ignitor (hot surface or spark electrode depending on model) provides the heat or spark at the correct time and location. Proper operation depends on correct orifice sizing, stable gas pressure, and the ignitor achieving the required temperature or spark timing; deviations in any of these parameters produce delayed ignition, unstable flames, incomplete combustion, or repeated valve cycling rather than reliable ignition on the first attempt.
- common failure symptoms: no ignition, continuous clicking with no flame, weak or floating flame, yellow tipping or soot indicating incomplete combustion.
- Compatibility checks: confirm gas type, orifice size, electrical connector and mounting orientation match the appliance specifications.
- Service tests: verify ignitor continuity or visible glow/spark, inspect for carbon contamination or physical damage, and confirm correct burner alignment with the orifice bore.
| Item | Description |
|---|---|
| Orifice | Precision gas restriction sized to match burner BTU and gas type; sizing controls flow rate and flame geometry. |
| Ignitor | Thermal element (glow) or spark electrode that initiates combustion and must reach/produce sufficient energy at the correct time. |
| Electrical/mechanical Fit | Connector voltage,mounting bracket position,and electrode gap/orientation must match the appliance for reliable ignition. |
In practical service, replace the assembly only with an identical or equivalent part and confirm the applianceS gas type and service manual specifications-match the part number and gas type rather than substituting based on visual similarity. For example, installing an orifice sized for natural gas on an LP-configured range will alter the air-fuel ratio and produce large, hot flames or yellowing; likewise, a degraded ignitor that no longer heats to operating temperature will cause extended valve open times and repeated ignition attempts. Technicians typically check ignitor continuity with a multimeter, inspect the electrode position relative to the burner port, and verify gas pressure and valve timing during commissioning or after replacement to restore reliable thermal/ignition performance.
How the 316237704 Frigidaire Ignitor/Orifice Assembly Operates Within the Gas Delivery and Ignition System
The 316237704 Frigidaire ignitor/Orifice Assembly combines the ignition element and the gas metering orifice into a single service component that mounts at the burner manifold. In operation the ignitor provides the localized ignition energy (spark or hot-surface glow depending on model) while the orifice converts manifold pressure into a defined gas jet for the burner. This assembly must match the appliance’s fuel type (natural gas or LP), manifold pressure and burner geometry; incorrect orifice size or an incompatible ignitor type will produce poor flame shape, slow light-off, or safety-valve cycling. Technicians should verify compatibility against the appliance model plate and replace the part with a like-for-like assembly to maintain designed heat output and safety interlocks.
Within the gas delivery and ignition sequence the assembly interfaces directly with the control valve and the oven or range ignition module: when a control calls for heat the valve releases gas upstream of the orifice, the orifice meters the flow and produces a concentrated jet at the burner, and the ignitor delivers the energy required to light the gas. Once the flame is established the system relies on flame sensing or thermocouple feedback to keep the valve energized; if the ignitor fails to heat or the orifice is partially blocked the result can be delayed ignition, yellow or lifting flames, or repeated valve shut-offs. Practical diagnostics include visual inspection for soot or debris at the orifice, measuring continuity or visible spark/sustained glow at the ignitor, and confirming correct burner flame pattern after replacement orifice sizing and manifold pressure verification.
- Ignition source – ignitor element provides spark or glow to initiate combustion.
- Gas metering – orifice sets flow rate and jet geometry for correct flame.
- Compatibility check – match to appliance model, gas type, and rated BTU output.
- Common symptoms of failure – delayed ignition, weak/yellow flame, repeated valve cycling.

Common Failure symptoms, Diagnostic Indicators, and Safety Concerns
The 316237704 Frigidaire Ignitor/Orifice Assembly integrates a hot-surface ignitor with a precisely sized gas orifice to initiate combustion and control burner performance.The ignitor must reach appropriate temperature quickly and evenly to light the gas when the valve opens; the orifice meters fuel flow to produce the intended air-fuel ratio and flame geometry for stable blue combustion. Common diagnostic indicators include ignition delay or failure to light, an ignitor that glows weakly or not at all, and flame characteristics such as yellow tipping or a lazy, low flame under high heat. Practical bench checks include a visual inspection for cracked or damaged ignitor elements, a continuity/resistance check on the ignitor circuit, and a visual/cleaning inspection of the orifice for carbon or debris that can restrict flow after spills or prolonged use.
Failing components can create safety hazards: accumulated unburned gas may produce a delayed ignition (“puff-back”), soot, or elevated carbon monoxide risk if combustion becomes incomplete. Do not operate the appliance if you smell gas; shut off the supply and ventilate before inspecting. Replacement requires matching the assembly to the appliance model or verifying equivalent orifice size and valve compatibility; incorrect orifice sizing can overpressurize the burner or produce unsafe combustion.After replacement, verify secure electrical connections, check for gas leaks at fittings with a soap solution or electronic leak detector, and confirm correct flame pattern and stable operation across low-to-high settings. for technician-level validation, use a multimeter on the ignitor circuit, a manometer to confirm supply pressure when suspect, and document that burner caps and crowns are seated properly before returning the appliance to service.
- No glow from ignitor or open circuit on resistance check
- Intermittent ignition or repeated clicking when gas valve energizes
- Weak, yellow, or sooty flame indicating partial obstruction or wrong orifice
- Delayed ignition or audible “puff” on lighting
- Visible damage to ignitor, corrosion, or buildup at the orifice
| Item | Description |
|---|---|
| Ignitor | Hot-surface element that heats to ignite gas; test by visual glow and electrical continuity |
| Orifice | precision port that meters gas flow; obstruction or incorrect size alters flame shape and heat output |
| Diagnostic tests | Visual inspection, resistance check on ignitor, leak test at fittings, and pressure check for supply verification |
Compatibility, Replacement Procedures, and Installation Considerations for Service Technicians
The 316237704 Frigidaire Ignitor/Orifice Assembly combines the ignition electrode and the fixed gas orifice into a single replaceable unit used on Frigidaire gas cooktops and ranges that employ an integrated ignitor/orifice design. The assembly’s primary function is twofold: the electrode provides the spark or hot surface to initiate combustion while the orifice meters the fuel flow to produce the intended flame size and heat output.Compatibility depends on orifice sizing and electrical connector type rather than physical appearance alone; technicians should verify the part number against the appliance’s service manual and compare the orifice diameter or any stamped identifiers before installation. Differences in gas type (natural vs. LP) require matching orifice geometry and proper regulator setting to maintain correct manifold pressure and flame characteristics.
Replacement and installation require standard safety and diagnostic steps: isolate gas and electrical supplies, relieve manifold pressure, and remove the burner assembly to access the module. During installation align the orifice seating and electrode position to the burner port, reinstall gaskets or seals, and tighten fasteners to the manufacturer’s torque range to prevent leaks or distortion.After installation perform a leak test at the fitting, verify ignition timing and flame quality across low-to-high settings, and confirm manifold pressure with a manometer when conversion between gas types or regulator adjustment is involved. If ignition delay, yellow tipping, or soot appears, re-check orifice size, electrode gap (per service specifications), and regulator setting before concluding the repair.
- Pre-install checks: verify part number,gas type compatibility,and inspect gaskets/seals.
- Installation steps: power/gas off, remove burner head, install assembly, torque, leak test.
- Post-install tests: ignition reliability, flame pattern, manifold pressure verification.

Q&A
What is the Frigidaire part 316237704 ignitor/orifice assembly and what does it do?
The 316237704 is an ignitor/orifice assembly used on many Frigidaire gas ranges and ovens.It combines the spark electrode (ignitor) that produces the spark and the gas orifice that meters the gas flow to the burner. Together it provides the ignition source and the correct gas feed so the burner lights reliably and burns with the correct flame.
Which Frigidaire models is part 316237704 compatible with?
Compatibility varies by model and production year. This OEM part is used on a range of Frigidaire/Frigidaire Gallery gas ranges and ovens.To confirm compatibility, compare your appliance model number (found on the oven frame or behind a kickplate) with the Frigidaire parts list or the vendor’s compatibility lookup. Do not rely only on visual similarity-always verify the part number against your model.
What are common symptoms that the ignitor/orifice assembly is failing?
Common signs include: no spark or no ignition at the burner, delayed ignition (popping or long ignition times), continuous clicking with no flame, weak or yellow/orange flame at the burner, or visible damage/sooting on the electrode. If the burner sparks but gas won’t light, the orifice can be clogged or the gas valve may not be opening.
How do I troubleshoot before replacing the 316237704?
First, ensure the range has power and gas supply. observe whether the electrode is producing a visible spark when a burner is turned on. If there’s continuous clicking but no spark, check the wiring to the module and electrode for damage or loose connections.If there is spark but no flame, check for a clogged orifice or blocked burner ports and verify the gas valve is operating. Clean the burner ports and orifice with care, but don’t enlarge holes.If you’re not pleasant with gas checks or electrical testing,call a qualified technician.
Can I test the ignitor/orifice assembly with a multimeter?
Testing depends on the type of ignitor. For spark electrode assemblies (like this part), a simple ohm reading is not a reliable indicator as the electrode is essentially a conductive probe-continuity checks might potentially be meaningless. The most effective test is visual: does it spark when the module calls for ignition? For safety and accurate diagnosis,also inspect wiring,the spark module,and power to the module. If you need electrical testing beyond basic checks, have a technician perform it.
How do I replace the 316237704 ignitor/orifice assembly safely?
Basic high-level steps: 1) Disconnect the appliance from electrical power and shut off the gas supply. 2) remove the cooktop or access panel to reach the burner/oven burner assembly per the service manual. 3) Remove the mounting screws and disconnect the electrode wiring and any gas line orifice fittings.4) Install the new assembly in the same orientation, tighten fittings to the specified torque, reconnect wiring, and reassemble. 5) Restore gas and electrical power and perform a leak check (soap/water solution) and functional ignition test. Because of gas and electrical hazards, if you are not experienced, have a qualified appliance technician perform the replacement.
Do I need to replace the entire assembly or can I replace only the ignitor or only the orifice?
The 316237704 is sold as a combined assembly. In many cases replacing the complete ignitor/orifice assembly is recommended because the components are sized and positioned to work together and are often packaged as one replaceable unit.Attempting to mix parts can cause fitment or performance issues. If a single component failure is definite and a compatible single replacement is available, that can be used, but OEM assemblies ensure proper alignment and orifice sizing.
Are aftermarket replacements acceptable and how long does this part typically last?
aftermarket replacements are available and can be less expensive, but quality varies. Using an OEM Frigidaire part ensures correct fit, orifice sizing and electrode placement. Lifespan depends on use, cleaning, and operating conditions; these parts commonly last several years but are subject to damage from spills, abrasive cleaning, or electrical/ignition module faults. If you have recurrent failures, check ignition module wiring and gas valve operation to address root causes.
