316536623 Frigidaire Ignitor/Orifice Assembly is a combined ignition and gas-metering component used on Frigidaire gas âappliances; it â¤consists of an electrical ignitor element paired with a calibrated orifice (jet) that controlsâ gas flow to aâ specific burner or burner group. In physical terms âthe assembly typically includes the ignitor electrode or ceramic hot surface, the metal orifice that sets flowâ rateand the mechanical mounting and connection points required to interface with the appliance’s gas manifoldâ and electrical harness.
Within the âŁappliance the ignitor/orifice assembly performs two closely linked functions: the ignitor provides the energy⤠required to initiate combustion and the orifice meters⤠the volume and pressure of gasâ delivered toâ the burner. The assembly âinterfacesâ directly withâ theâ appliance gas supply and manifold, the gas valve that controls on/off flow, the burner head were combustion occursandâ theâ appliance⢠control system that timesâ ignition and âmonitors flame presence. Correct sizing and operation of both the ignitor and the orifice affect ignition reliability, flame pattern, âŁcombustion efficiencyand safe operation of âŁthe appliance.
This article explains how the 316536623 assembly functions, how⣠toâ determine model⤠compatibility and the differences that matter (for example âorifice size and fuel type), âcommon failure symptoms to recognize, basic troubleshooting paths a technician can followand key replacement considerations such as matching orifice specifications, electrical connector type,â sealing and mounting requirements, â¤and safety checks to perform after replacement. The aim is to provide practical technical context so technicians, engineersand appliance owners can identify issues, evaluate compatibilityand make informed decisions about repair or⤠replacement while observing applicable⤠safety and regulatory practices.

Functional Role and System Integration of the Ignitor/orifice Assembly in Frigidaire Gas Appliances
The 316536623 Frigidaire ignitor/Orifice Assembly combines the ignition element and a precisely sized gas orifice into a single service component that mounts at⣠the burner âhead. Functionally, the ignitor provides the ignition energy (spark⣠or hot surface) atâ the moment the gas valve opens, while the orifice meters the volumetric flow âandâ creates the correct jet velocity â˘for stable combustion at the burner ports. Proper behavior of the assembly depends on matching orifice diameter to the appliance’s manifold pressure and fuel type; an undersized orifice will produce weak heat and long ignition times, while an â¤oversized orifice can cause excessive flame lift or yellowing. Technicians should confirm the assembly’s approved gas typeâ (natural vs. LP) âand model compatibility before replacementâ to ensure correct combustion characteristicsâ and regulatory compliance.
From an installation and diagnostic perspective,the assembly interfaces mechanically with the burner bowl⣠and electrically âwith the control module; poor seating,a fouled orifice,or a cracked ignitor âwill each produce distinct âsymptoms. Common practical checks include a continuity/resistance test of the ignitor âwith a multimeter, visual inspection of orifice ports for carbon or debrisand â¤verification of manifold pressure â¤and valve operation during âlive testing. Such as,a cooktop that clicks repeatedly without sustaining a flame often indicates a faulty ignitor or intermittent electrical connection,while persistent⣠yellow tips or sooting points to incorrect orifice sizing or insufficient primary air. When converting fuel âtypes or replacing a worn unit, replace the orifice with the specified size âand recheck flame pattern and safety interlocks after installation.
- Typical diagnostic indicators: continuous clicking (ignition fault), delayed ignition (restricted orifice), yellow flame or sooting (air/fuel imbalance)and⤠no spark (ignitor failure).

Operational Mechanics of the 316536623â Frigidaire ignitor/Orifice â¤Assembly and Gas Flow Dynamics
316536623 frigidaire Ignitor/Orifice Assembly is an integrated consumable designed to âboth initiate combustion and regulate gas flow at a specificâ burner. The ignitor element supplies the thermalâ or spark energy⤠needed to ignite the fuel-air mixture, while the orifice is aâ precision-machined jet that sets the volumetric flow ârate by⤠creating a controlled pressure drop⢠between the supply pressure and the⢠burner throat. The two elements are matched so that ignitionâ energyorifice diameterand burner geometry produce a stable, properly sized⤠flame across the intended operating pressure range; swapping an orificeâ sized for aâ different gas type âŁor aâ degraded ignitor will change flame characteristics and may prevent reliable ignition.
Gas flow through the orifice follows predictable fluid-dynamic behavior: volumetric flow is proportional to orifice area and the square root of the pressure differentialand flame shape depends on the local air-fuelâ ratio â¤and burner aeration. Practical consequences include delayed ignition or sustained yellow⢠tipping when the orifice is partially cloggedand longer spark duration or failure-to-light when the ignitor has lost output due to age âor contamination. Technicians commonly verify supply pressure, inspect the orifice for debris, confirm âcorrect orifice for the gas type (natural gas vs. LP)and measure ignition dwell time to diagnose faults; these checks distinguish between a flow-rate problem (orifice) and an energy-delivery problem (ignitor).
- Common symptoms: delayed ignition, weak or lifting flame,â yellow/sooty combustion,â or intermittent lighting.
- Key compatibility concerns: correct orifice sizing for gas type and matched ignitor output for the specific Frigidaire burner assembly.
- Typical checks: visual⣠orifice⢠inspection, supply-pressure verificationand ignition output measurement.
| Item | Description |
|---|---|
| Ignition method | Thermal or spark element paired with the orifice to ensure rapid, repeatable ignition. |
| Gas compatibility | Orifice diameter and seat geometry are gas-specific; conversion⤠requires⢠matched orifice and calibration. |

Diagnostic Indicators: Common Failure Symptoms â˘and â˘Measurement Criteria for Ignitor/Orifice Faults
the 316536623 Frigidaire Ignitor/orifice Assembly combines the burner âorifice that âmeters gas flow with the ignition electrode/ignitor that initiates combustion; together this assembly governs both fuel delivery and reliable spark or glow ignition for compatible Frigidaire cooktops and ranges. Technicians should understand that the assembly’s orifice diameter, thread orientationand electrode position determine âcompatibility and flame characteristics-misaligned electrodes, incorrect orifice sizingor degraded insulation will produce âdelayed ignition, continuous sparkingor asymmetric flames.Visual inspection for carbon deposits, cracked ceramic around theâ ignitorand correct seating of the orifice in the burner head quickly distinguishes mechanical fit issues from electrical or gas-supply faults.
- Ignition â˘delay or repeated sparking at the module after theâ valve opens – check electrode insulation and secure mounting.
- Yellow, liftingor noisy flame – inspect⢠orifice size, burner portsand manifold pressure for restricted flow or incorrect gas type.
- open⢠circuit or very high resistance on an ignitor designed for continuity – test âŁwith a multimeter across the ignitor leads.
- intermittent ignition only at certain knob positions – examine orifice alignment and spark gap for contamination or incorrectâ spacing.
| Item | Description |
|---|---|
| Electrode gap | Typical service range: ~2-4 mm;⤠larger gaps reduce spark reliability, âsmaller gaps may short to the burner cap. |
| Ignitor continuity | Verify closed circuit where applicable; consult model service data for nominal ohms for hot-surface ignitors. |
| Flame quality | Steady blue cone with âinner feather; yellow tipping or lifting indicates â¤fuel/air imbalance or orifice⣠restriction. |
Diagnostic measurement begins with safe isolation of power and gas: shut off gas and⤠electrical supply before⢠probing. Use a multimeter to check continuity⣠and resistance, a feeler gauge to verify electrode gapand a manometer to confirm manifold pressure when flame anomalies⤠suggest improper flow; compare observed valuesâ to the appliance’s service manual. Practical troubleshooting sequence: confirm⢠correct part fit and clean ports,â verify ignitor electrical integrity, then check gas pressure and⢠orifice condition-this approach separates installation/compatibility⢠faults from electrical or supply problems and reduces unneeded part replacements.
replacement Considerations, Model Compatibility and Step-by-Step Installation Procedures
The 316536623 Frigidaire Ignitor/Orifice Assembly combines the ignition element and the gas metering orifice into a single replaceable unit⣠that governs both spark/hot-surface ignition and the initialâ gas flow to the burner. Functionally,⢠the ignitor provides the energy to light the gas while the â¤orifice sets the volumetric flow rate and thus the flame size and combustion characteristics; technicians must confirm the assembly’s mounting footprintorifice bore size (natural â¤vs LP)and electrical connector configuration against the appliance service documentation before installation. Practical indicators that âthis assembly⤠may need replacement include ârepeated failed ignition attempts, delayed ignition accompanied by strong odoror an ignitor that glows but does not produce a spark – however, these symptoms can also arise from manifold pressure, control module faultsor wiring issues, so verify those systems during diagnosis.
- Shut off gas supply and electrical power before starting disassembly.
- Remove burner grate⤠and âcap, then⤠unfasten retaining screws to access the assembly.
- Document and⣠photograph connector orientation and bracket position for â¤reassembly.
- Compare the old and new⣠assemblies for orifice size, thread typeand electrical â¤pinout before installation.
- Reinstall, torque screws to⤠manufacturer specification, reconnect wiring, restore gas and power, then perform a leak testâ and ignition trial.
| Item | Description |
|---|---|
| Primary function | Provide ignition energy and meter gas flow to create a âŁstable burner âflame |
| Compatibility factors | Mounting footprintorifice bore âŁ(natural/LP), electrical connector typeand screw locations |
| Commonâ failure modes | Open or shorted â˘ignitor element, clogged orifice, cracked insulator,⢠or loose electrical connection |
Replacement considerations include verifying gas type and⢠any required conversion parts: switching from natural gas to LP requires a correctly sized orifice and sometimes a different regulator âor conversion⤠kit; installing an assembly with an incorrect bore will alter air-fuel â˘ratio and â¤flame stability. During installation ensure sealing⢠surfaces and gaskets seat properly and that wire â˘insulation is routed away from⤠high-heat paths; after assembly,confirm ignition⢠timing and⢠flame characteristics under typical burner settings and re-check for leaks at â˘the orifice and manifoldâ connections. If ignition problems persist after correct â¤assembly replacement, systematically test the control â¤module output, manifold pressureand continuity of the ignitor circuit to isolate the fault.
Q&A
What is the 316536623 Frigidaire â˘Ignitor/Orifice Assembly and what does it do?
The 316536623 is an ignitor/orifice assembly used on Frigidaire gas cooktops and ranges.Itâ combines the ignition electrode (theâ piece that creates the spark to light the gas) with the burner orifice â˘(the small jet that meters gas flow into the burner).⤠Together they âcontrol and initiate the burner flame and ensure proper gas delivery â˘at the burner port.
How do⢠I know if the ignitor/orifice assembly is bad?
Common symptoms of a âfailing assembly include no spark or intermittent sparking at the burner, continuous clicking without lighting, a weak or unstable flame, âor a gas smell when the âburner is operating but ânot igniting. physical signs can include a cracked or corroded electrode, a clogged orificeor visible damage to wiring orâ connectors. Always rule out the ignition moduleâ and wiring harness first, since those canâ produce similar symptoms.
Can I test the ignitor/orifice assembly myselfand how?
Yes, basic testing is absolutely possibleâ but requires care. First shut off power and gas. Visually inspect the electrode and orifice forâ damage or debris. you can reapply power (gas off) and âattempt to observe a spark whenâ a burner control is turned on (avoid âtouching components). A multiâmeter continuity check can sometimes indicate an open circuit in an ignitor â¤lead, but âmany spark electrodes do not give a âdefinitive resistance reading, âso a continuity check is⢠not always conclusive. If unsure, consult a technician. Never test withâ gas on unless you’re prepared to⣠follow safe ignition procedures.
How do I replace the 316536623 assembly – basic steps and safety tips?
Basic replacement steps: â1) disconnect electrical power to the appliance and shut off â˘the gas supply. 2) Remove the cooktop/burner cap and any screws or fasteners securing the assembly.3) Note the orientation and wire connections,disconnect the ignitor lead,and remove the old assembly. 4) Installâ the new assembly in the same orientation, reconnect wiringand secureâ fasteners. â5) Restore gas and power âand perform a leak âcheck (soapy water) at the orifice connection, then test ignition and flame characteristics. Safety â˘tips:â always turn⣠off gas and electricity before âŁstarting, do a âleak test after installationand⢠if you smell gas at any time stop and ventilate the area âŁand call a professional.
Do I need to âŁreplace the entire assembly or can I âjust replace the orifice or electrode?
Itâ depends on the failure: if the orifice is clogged or damaged you can replace just theâ orificeand if the electrode is âcracked or worn you can replace only the electrode where available. However, many service parts are sold as assemblies for â˘convenience and to ensure correct fit and alignment; replacing âthe âcomplete assembly is often recommended to avoid mismatched components and to ensure reliable operation.
Are there different orifice sizes and do I need to match them?
Yes – orifice size determines gas flow âand flame â˘sizeand different models (and different fuel types or altitudes) may use different orificeâ sizes. Always use the âOEM-specified orifice size for your appliance model. Do not substitute an orifice of an incorrect size; incorrect sizing can cause poor performance, unsafe operationor regulatory noncompliance.Check your appliance model number and the parts diagram or consult Frigidaire documentation or a qualified technician to confirm the correct orifice.
any installation tips⤠or common mistakes to avoid?
Key tips: 1) Turn off gas and power before working.2) Keep the electrode gap and orientation as specified – electrodes must be positioned correctly relative⤠to the burner ports for reliable ignition. 3) Avoidâ overtightening the orifice fitting; snug and leakâfree is correct. 4) Replace any brittle or damaged wiring⤠and connectors. 5) After installation, perform⢠a gas leak test and check flame color and stability (steady blue flameâ is normal). â˘If you’re not confident with gas appliance work, hire a licensed service technician.
