The 316237704 Frigidaire Ignitor/Orifice Assembly is an integrated ignition and gas metering component used in Frigidaire gas cooking appliances; it combines an ignitor element (spark or hot-surface type depending on the model) with a precisely sized orifice/nozzle to deliver and ignite the fuel at a burner port. Physically, the assembly typically mounts at the burner head or manifold and includes the ignition electrode or hot surface, the gas orifice, and associated mounting hardware and electrical connectors necessary to interface with the appliance control system.
Within the appliance, the ignitor/orifice assembly serves two primary functions: to introduce a controlled volume of gas to the burner and to provide the energy source that initiates combustion. It interfaces directly with the gas supply/manifold, the gas valve that controls flow, and the appliance control and safety circuits that command ignition and detect accomplished flame establishment. Proper operation of the assembly affects ignition timing, flame stability, combustion efficiency, and the behavior of safety interlocks such as flame sensing and automatic shutoff.
This article will explain the assembly’s operating principles and how to verify model compatibility, describe common failure symptoms (for example, no ignition, delayed lighting, weak or unstable flame, continuous sparking, or visible sooting), outline systematic troubleshooting checks technicians can perform, and summarize practical replacement considerations such as matching orifice size and thread sealing, electrical connector verification, and post-replacement testing and leak checks. Practical safety reminders and diagnostic focus points will be provided to help technicians, engineers, and appliance owners assess and replace the component correctly without overstating repair complexity or performance expectations.

Function and Role of the ignitor/Orifice in Frigidaire Gas Burner Systems
The 316237704 Frigidaire Ignitor/Orifice Assembly integrates the ignition element and the fixed gas metering orifice into a single serviceable module used on Frigidaire gas burners. In operation, the burner valve opens to admit gas through the calibrated orifice while the ignitor provides the energy to initiate combustion; flame sensing then confirms ignition to the control electronics. proper performance depends on matched mechanical and electrical interfaces – orifice diameter and connector pinout are critical – as an incorrect orifice changes burn rate and flame geometry,and an incompatible electrical connector can prevent the ignitor from receiving the proper voltage or signal timing.
Technicians evaluating this assembly should recognize common failure behaviors and the practical compatibility checks required before replacement.Symptoms such as repeated ignition attempts with no sustained flame, a weak or yellowing flame, slow heat rise, or control lockouts point to a faulty ignitor, clogged orifice, or wrong gas type/orifice pairing. When replacing the assembly, confirm the appliance’s gas type (natural gas versus LP), verify mounting orientation and gasket sealing to prevent leaks, and follow basic electrical checks (supply voltage and continuity) to distinguish between ignitor failure and upstream valve or control problems.
- Common symptoms: repeated clicks without flame, delayed ignition, soft/yellow flame, or control lockouts.
- Fast checks: verify valve voltage at ignition, confirm visible spark or hot surface activity, inspect orifice for debris, and confirm correct gas type.
- Compatibility considerations: match part number, orifice sizing, thread type, and connector pinout to the appliance model.

How the 316237704 Frigidaire Ignitor/Orifice Assembly Operates Within the Ignition and Gas Delivery Circuit
The 316237704 Frigidaire Ignitor/orifice Assembly pairs a hot-surface ignitor element with a precisely sized gas orifice to control both the electrical initiation and the volumetric flow of gas to a burner. In the ignition and gas delivery circuit, the ignitor serves as the load that draws current when the oven control commands ignition; that current flow is the condition the safety gas valve needs to energize and open. The orifice, fitted at the burner inlet, meters the gas to the correct flow rate and pressure for the designed burner geometry, so replacing the assembly with the correct part number preserves intended BTU output and combustion characteristics on compatible Frigidaire ranges and ovens.
Behavior under normal operation follows a simple sequence: the control module applies voltage to the ignitor, the ignitor reaches its operating temperature and conducts the required current, and the gas valve opens to allow flow through the matched orifice where the mixture is ignited. common fault modes include reduced ignitor current (from a weakened element or open circuit) that prevents valve actuation, and partial orifice restriction that causes weak or yellow flames. Technicians typically verify operation by measuring ignitor resistance or current draw, inspecting the orifice for debris or corrosion, and confirming the assembly’s part number and mounting orientation to ensure electrical and mechanical compatibility with the appliance model.
- Key features: combined ignition load and flow metering, OEM-matched orifice sizing, direct replacement fit for specified Frigidaire models.
- typical symptoms of failure: no valve actuation, delayed ignition, weak flame, or intermittent operation.
- Service checks: continuity/current test of ignitor, visual/orifice cleaning, and verification of correct part number.

Common Failure Symptoms and Diagnostic Procedures for Ignitor/Orifice malfunctions
The 316237704 Frigidaire Ignitor/orifice Assembly combines the heat/spark-producing element of the ignitor with the gas-jet metering of the orifice to initiate and control combustion at a burner. In normal operation the ignitor must either reach the required surface temperature or deliver a consistent spark while the orifice precisely meters fuel flow for the intended gas type (natural gas or LP). Compatibility is determined by both mechanical fit and orifice sizing: using an orifice sized for the wrong gas or an ignitor with incorrect electrical characteristics changes flame shape, combustion efficiency, and can trigger safety interlocks. For technicians, functional behavior to watch for includes ignition timing, flame color and stability, and whether the assembly receives the correct control signals and gas pressure during a start sequence.
- No ignition: verify power and control voltage at the ignitor connector, then check ignitor continuity; a dead ignitor or an open circuit is a common cause.
- Delayed ignition or sooting: inspect the orifice for clogging or incorrect size and confirm supply pressure; delayed opening of the valve or an undersized/blocked orifice produces accumulation and combustion flashes.
- Continuous clicking or rapid retries: confirm the ignitor actually heats or sparks and that the control board is receiving correct feedback; persistent retries often indicate a weak ignitor or safety valve timing fault.
- Yellow or uneven flame: check orifice ports, air shutter/mixture adjustments, and mounting alignment; improper gas to air ratio or partial obstructions alter flame chemistry.
- Gas odor or leaks: shut off gas instantly and inspect the orifice threads and seals; loose fittings or damaged seats create hazardous leakage.
| Item | Description |
|---|---|
| No ignition | Ignitor open or failed control voltage; check continuity and connector voltage during start. |
| Sooting/delayed ignition | Clogged orifice, wrong orifice size, or low gas pressure leading to fuel-rich combustion. |
| Yellow/uneven flame | Incorrect air/gas mixture, partial obstruction of orifice, or misaligned burner components. |
Diagnosing failures requires a methodical sequence: shut off gas and power, perform a visual inspection for physical damage or carbon build-up, then measure ignitor continuity with a multimeter and verify control voltage at the harness during a start attempt. If electrical checks are within expected ranges but ignition remains unreliable, remove the burner assembly and inspect the orifice for debris or the wrong jet size; cleaning with appropriate tools may restore flow but replacement is required if ports are eroded or warped. Check model and gas-type compatibility before installing a replacement-fitting a 316237704 Frigidaire Ignitor/Orifice Assembly with an incorrect orifice size can produce high flames, poor combustion, or activate safety shutoffs-so when in doubt replace with the specified part number and verify combustion characteristics (steady blue flame, correct lift) under load.
Compatibility, Replacement Considerations, and Installation Procedure for the 316237704 Frigidaire Ignitor/orifice Assembly
The 316237704 Frigidaire Ignitor/Orifice Assembly combines a spark electrode and a precision gas orifice into a single serviceable unit so the ignition source and fuel metering are matched for correct combustion. Functionally,the electrode provides a repeatable high-voltage spark at the burner port while the orifice determines gas flow rate; together they control ignition timing,flame size,and burner stability.Compatibility depends on three physical and functional factors: the orifice jet size (natural vs LP), the electrode length and mounting orientation, and the electrical connector/grounding arrangement. Technicians should confirm the appliance model number and compare the physical mounting pattern and jet marking rather than relying solely on cross-reference lists, because an assembly that fits mechanically can still produce poor combustion if the jet sizing or electrode position differs from the factory specification.
Replacement and installation are straightforward when performed methodically: verify the appliance electrical power and gas supply are shut off, document the existing electrode gap and mounting orientation, remove the burner components to access the assembly, and install the new unit using the original fasteners and gaskets. After reassembly, restore power and gas and perform an ignition test plus a leak check at the orifice; observe several ignition cycles for consistent spark and stable blue flame. common service indicators that justify replacement include intermittent or absent sparking, delayed ignition with excessive clicking, persistent yellow or lifting flame, or detectable gas odor during the ignition cycle.
- Compatibility checkpoints: gas type (Natural/LP), physical mounting pattern, connector style, and orifice jet marking
- installation checkpoints: document electrode position, secure gasket/seal, torque fasteners to factory spec, perform leak test and ignition cycle verification
- service symptoms: intermittent spark, delayed ignition, yellow flame, or gas odor
| Item | Description |
|---|---|
| Orifice | Jet sized for specific gas type; determines flow rate and flame characteristics |
| Electrode | Position and gap relative to burner port affect spark reliability; match factory orientation |
| Mounting/Connector | Screw pattern and electrical connector must align with appliance harness for proper grounding and ignition |
