The 316237704 Frigidaire Ignitor/Orifice Assembly is a combined ignition and gas metering component designed for use in gas cooking appliances. It pairs an ignitor element-either a hot-surface or spark-type electrode depending on the model-with an orifice that meters gas flow to a burner, and is supplied as a modular replacement part for service and repair.
Inside an appliance, this assembly interfaces directly with the burner head and the appliance’s gas supply, and it is indeed controlled by the range or oven control circuitry and gas valve. The ignitor provides the energy required to initiate combustion while the orifice provides a fixed flow restriction that sets the fuel-to-air ratio at the burner; together they affect ignition reliability, flame stability, and safe operation. Typical applications include Frigidaire gas ovens and ranges where accurate ignition timing and controlled gas delivery are required for proper cooking performance and to prevent unburned gas accumulation.
In the following article readers will find a technical overview of how the 316237704 assembly functions, guidance on model compatibility and physical/ electrical interface considerations, common failure symptoms and diagnostic tests, practical troubleshooting steps to isolate ignitor versus gas-delivery issues, and replacement considerations such as mounting orientation, sealing, connector types, and safety procedures to follow when servicing gas appliances. The focus is on technical detail useful to technicians, engineers, and informed appliance owners performing diagnosis or repair.

Function and Role of the ignitor/Orifice Assembly in Gas Delivery,flame Establishment,and Safety Interlocks
The 316237704 frigidaire Ignitor/Orifice Assembly combines an electrical ignitor element with a calibrated orifice to control gas delivery and initiate combustion. When the range control calls for heat,the control opens the gas valve and energizes the ignitor; the orifice meters the gas flow so the ignitor can reliably establish a stable flame. Proper interaction between the ignitor’s energy output (glow intensity or spark timing) and the orifice diameter determines ignition timing,flame shape,and combustion quality. This assembly must match the appliance’s gas type (natural vs.LP), valve pressure and connector style-an orifice sized for LP or higher valve pressure will produce an over-rich mixture if incorrectly installed, while an undersized orifice can cause weak or unstable flames and repeated ignition attempts.
- Gas metering: orifice calibrates flow to achieve correct air-fuel ratio for stable flame.
- Ignition initiation: ignitor provides the thermal or spark energy to light the gas stream.
- Safety interaction: ignition timing and flame presence feed back to the control/thermocouple for valve shutoff on failure.
- Compatibility concerns: must match gas type, pressure rating, and mounting/connector configuration.
| Item | Description |
|---|---|
| Ignitor behavior | provides thermal or spark energy; slow glow or failed spark delays ignition and triggers lockout. |
| Orifice function | Fixed orifice diameter meters fuel; size varies by gas type and model to set correct flame geometry. |
| common symptoms of failure | Delayed ignition,small yellow flame,repeated valve shutoff,or no flame despite ignitor activity. |
Troubleshooting and service require checks of both electrical and fluid elements: verify ignitor voltage/current waveform and physical integrity, confirm orifice and burner ports are free of debris, and confirm the replacement assembly matches the appliance’s gas type and control interlock expectations. For example, a range that clicks repeatedly before lighting frequently enough has a weak ignitor or partially blocked orifice; a flame that lights but then goes out may indicate a faulty flame sensor or mismatched orifice pressure. When replacing the assembly, technicians should confirm the 316237704 part number or the equivalent specification (orifice size, connector type, and ignitor characteristics) to prevent combustion inefficiency or unneeded safety lockouts.
How the 316237704 Frigidaire Ignitor/Orifice Assembly Integrates with the Gas Valve, ignition Circuit, and Burner Orifice Geometry
The 316237704 Frigidaire Ignitor/Orifice Assembly combines the ignition electrode/ignitor element with a machined gas orifice so that the electrical and fluid functions are pre-aligned at the burner head. In operation, the ignitor provides the energy required to initiate combustion (either as a spark electrode or a hot-surface element, depending on system design) while the orifice meters gas flow to produce the intended local pressure and jet velocity. correct electrical resistance or spark gap and the correct orifice diameter are both critical: the ignitor must present the expected electrical signature to the control/ignition module so the gas valve is timed to open only when ignition energy is present, and the orifice geometry must match regulator pressure and burner port layout to yield a stable, non-sooty flame.
Integration with the gas valve and ignition circuit depends on matching electrical and mechanical specifications. The control or spark module supplies voltage/current to the ignitor and typically only allows the gas valve to open when the ignitor indicates a ready state (sufficient heat or confirmed spark/ionization); if the ignitor resistance or electrode position is out of spec the valve may not latch or may produce delayed ignition. Similarly, an orifice sized for the wrong gas (natural vs. LP) or installed with improper alignment will change flame shape and combustion stability, potentially causing pilot failure, regulator hunting, or safety shutoff. Practical diagnostics include measuring ignitor resistance or electrode continuity, observing ignition timing relative to valve actuation, and inspecting flame color and lift; common corrective actions are replacing the assembly with the OEM 316237704 unit matched to the appliance, verifying spark gap or HSI resistance, and confirming the orifice size and seating are correct for the supply gas.
- Electrical interface: required voltage/current signature to the ignition module
- Mechanical fit: thread, mounting flange, and sealing to the manifold/gas valve
- Gas metering: orifice diameter tied to regulator pressure and burner port geometry
- Service indicators: delayed ignition, yellow/sooty flame, or valve cycling

Common Failure Symptoms and Diagnostic Measurements for Ignitor/Orifice Malfunction
The 316237704 Frigidaire Ignitor/Orifice Assembly combines the ignition element and the burner orifice so the ignition energy and gas flow are matched to the appliance’s gas system. The ignitor provides either a hot surface or spark source to initiate combustion while the orifice meters gas flow to the burner; compatibility between the two is critical because an undersized orifice or a weak ignitor will produce slow ignition, low flames, or unstable combustion. Technicians should consider mechanical wear (cracks, erosion) and contamination (solder flux, food debris) as common causes of degraded performance; an orifice that has been swapped between models or replaced with the wrong size will change flame height and combustion characteristics even if the ignitor tests good electrically.
Diagnosing failures requires both visual inspection and electrical/gas measurements. Use a multimeter to check ignitor continuity and cold resistance,and use an ammeter or clamp meter to confirm operational current draw when the ignitor is energized; low current under load commonly indicates an aging hot-surface ignitor that won’t pull the gas valve open. Inspect the orifice for partial blockage and confirm manifold pressure and flame appearance – weak, lifting, or yellow flames point to restricted flow or improper orifice sizing, whereas repeated clicking with no flame usually indicates a fuel delivery problem rather than an ignition electrode failure. For practical troubleshooting, compare measured values to the appliance service manual and replace the assembly when measured behavior (resistance, current, flame pattern) deviates materially from the documented specifications for that model.
- No ignition: check for spark or hot-surface continuity and verify gas valve operation under applied ignitor current.
- Slow ignition or delayed flame: measure ignitor current under load and inspect orifice for partial blockage.
- Weak or low flame: inspect orifice size and manifold pressure; confirm correct assembly compatibility.
- Yellow or sooty flame: suspect incorrect orifice or improper fuel/air mixture; verify flame appearance after cleaning orifice.
- Intermittent firing: test for high-resistance connections, cracked ignitor ceramics, or fluctuating manifold pressure.
| item | Description |
|---|---|
| Ignitor cold resistance | Typical range varies by design; compare to service manual. Meaningful deviation from the specified ohms suggests failure. |
| Ignitor operational current | Measured under power at the ignitor; low operational amperage commonly indicates a failing hot-surface ignitor that cannot open the gas valve. |
| Orifice condition | Inspect for debris,corrosion,and correct diameter for the model; partial blockage reduces flow and alters flame shape. |
| Flame appearance | Blue, steady flame indicates correct operation; yellow tipping, lifting, or sputtering suggests flow or ignition mismatches. |
Compatibility, Replacement Considerations, Installation Steps, and Post‑Install Troubleshooting Procedures
the 316237704 Frigidaire Ignitor/Orifice Assembly combines the glow ignitor element and precision gas orifice into a single replaceable unit that controls ignition timing and the initial gas jet for a burner. functionally,the ignitor provides the required thermal or spark energy to initiate combustion while the orifice sets the gas flow rate; mismatches in orifice size,manifold pressure,electrical connector type,or mounting geometry will change flame shape,heat output,and safe ignition behavior. Before replacement, verify the appliance model number, gas type (natural or LP), connector arrangement, and orifice stamp – swapping an assembly with the wrong orifice can produce a weak or sooty flame, delayed ignition, or regulator/valve stress. Technicians should also inspect the associated wiring harness,ground continuity,and gas valve operation as an or else serviceable ignitor assembly will not function correctly if the valve does not open or if the control board does not supply the correct drive voltage.
- Safety: shut off gas and electrical supply and relieve manifold pressure before disassembly.
- Remove burner cap and mounting screws; note orientation of the ignitor and orifice for correct reassembly.
- Confirm gas type and replace orifice if converting between NG and LP; tighten to specified torque with a new gasket or seal.
- Restore power and gas, perform a leak test, then observe glow time (or spark behavior) and flame enveloping the orifice.
- If ignition issues persist, measure ignitor resistance and control voltage, verify manifold pressure, and check for grounding/rectification faults.
Installation requires mechanical alignment and electrical connection checks: the ignitor must be seated so its tip is within the specified distance from the burner head and the orifice must be centered in the flame path to achieve proper combustion.Post‑install troubleshooting focuses on measurable parameters – expected cold resistance for a glow ignitor, time-to-glow (typically a few seconds), stable flame length, and absence of continuous sparking.Persistent symptoms and likely causes include continuous sparking (failed flame sensing or poor ground), delayed ignition (weak valve pressure or clogged orifice), and sooting or yellow tips (incorrect orifice size or insufficient primary air). use diagnostic measurements (multimeter for resistance/voltage,manometer for manifold pressure) to identify whether to re-seat/replace the ignitor assembly or address upstream fuel or control faults.

Q&A
What is the Frigidaire part 316237704 (Ignitor/Orifice Assembly)?
The 316237704 assembly is an OEM replacement component for certain Frigidaire gas ranges/cooktops that combines an ignition element (the ignitor/electrode) and the gas orifice (the small jet that meters gas to the burner). It replaces the factory unit that both produces the spark (or heats to ignite, depending on design) and directs gas to the burner head. Always verify compatibility with your appliance model number before ordering.
How do I know if the 316237704 ignitor/orifice assembly is failing?
Common symptoms of a failing assembly include: burners that will not light, intermittent ignition, long ignition delays, weak or irregular flames, or constant clicking with no ignition. Visual signs include a cracked or corroded electrode, blocked orifice, damaged wiring or connector, or discoloration of the ignitor. If you smell gas without ignition,stop and follow safety procedures instantly.
can I test the ignitor portion with a multimeter?
Yes – you can perform preliminary electrical tests, but exact resistance values depend on the ignitor type. For glow-style ignitors you should see continuity; an open circuit (infinite resistance) indicates a failed ignitor. Spark electrodes typically do not have a simple resistance test and are checked visually for damage and by observing whether a spark is produced during a normal ignition cycle. Refer to the appliance service manual for the correct test procedure and resistance specifications. If unsure, consult a qualified technician.
Is it safe to replace the 316237704 myself, and what safety steps should I take?
Replacement is absolutely possible for experienced DIYers, but you must follow safety precautions: turn off the appliance’s electrical power, shut off the gas supply, and work in a well-ventilated area. After installation,perform a leak check (soapy water) at gas fittings and verify proper ignition and flame pattern. If you are not pleasant working on gas appliances, or if you detect a gas leak, hire a licensed technician. Never attempt repairs if you smell natural gas - evacuate and call your gas supplier.
Do I need to clean the orifice,or should I replace the whole assembly?
A partially blocked orifice can frequently enough be cleaned with compressed air or a soft brush,but delicate orifice jets can be damaged easily. Many technicians recommend replacing the orifice/ignitor assembly if the ignitor is bad or the orifice is severely clogged, because the assemblies are relatively inexpensive and replacement ensures proper fit and function. Avoid using metal wires or drills to clean the jet,as that can change the orifice size and affect performance.
Will replacing the 316237704 always fix ignition problems?
Not always.Ignition problems can be caused by several components: the ignitor/orifice assembly,the spark module/ignition switch,wiring/connectors,the appliance control board,or fuel supply issues. Replacing a faulty 316237704 will fix problems caused by that assembly,but if the root cause is elsewhere you’ll need to diagnose those parts as well. Start with a careful inspection and, if needed, sequentially test other ignition system components.
How do I confirm this part fits my Frigidaire appliance?
Locate your appliance model number (usually on a tag inside the oven door, behind the door, or on the back) and use that model to search Frigidaire’s parts lookup, authorized parts retailers, or the OEM parts diagram. Cross-reference 316237704 with the parts diagram for your specific model; if in doubt, contact Frigidaire or a certified parts supplier to confirm fitment before purchasing.
