316536623 Frigidaire Ignitor/Orifice Assembly is a combined ignition and gas metering component used on Frigidaire gas appliances, typically ovens and ranges. As a service part it integrates a gas orifice – the fixed orifice that meters fuel to a burner – with an electrical ignitor element (either a hot surface/glow ignitor or a spark-type ignitor depending on the model). The assembly is a discrete replaceable module designed to fit specific burner housings and supply both the controlled gas flow and the initiation source required for combustion.
Inside the appliance, the ignitor/orifice assembly interacts directly with the gas supply, burner, gas valve, and the appliance’s control and safety circuitry. the orifice determines the gas flow rate at a given inlet pressure, controlling flame size and combustion characteristics, while the ignitor provides the energy to light the gas when the control calls for heat. It also works in concert with thermostats or electronic control modules, flame detection or flame rectification systems, and pressure-regulating components to maintain safe, reliable operation and correct temperature regulation.
In this article readers will find a technical overview of the 316536623 assembly’s function and how it is indeed used across compatible Frigidaire appliances, guidance on identifying compatible models and part variations, common failure symptoms (such as no ignition, delayed ignition, weak or yellow flames, or erratic operation), and structured troubleshooting steps to isolate ignition versus fuel-delivery problems. The article will also cover practical replacement considerations – electrical and gas isolation, gasket and mounting details, correct fastener torque, verifying inlet pressure and orifice sizing, and safety checks after installation – to help technicians, engineers, and informed appliance owners make safe, effective service decisions.

Function and Role of the Ignitor/Orifice Assembly in Frigidaire Gas Burners
The 316536623 Frigidaire Ignitor/Orifice Assembly is a combined ignition electrode and gas metering element that mounts at the burner to align the gas jet with the ignition source.In this assembly the orifice size and orientation control the volumetric flow and spray pattern while the ignitor provides the required energy (spark or hot surface) at a consistent location relative to the gas stream.Correct function depends on matching the orifice to the appliance’s manifold pressure and burner rating so that flame shape, stability, and heat output meet the original design parameters.
- Key features: integrated orifice and ignitor, fixed electrode gap and mounting geometry, and part-specific orifice sizing.
- Common failure symptoms: delayed ignition, intermittent or absent spark, yellow or lifting flame, sooting, or a gas odor prior to ignition.
- Service considerations: check for clogged orifice passages, cracked ceramic insulation, electrode erosion, and correct orientation/seat at the burner head.
| Item | Description |
|---|---|
| function | Provides localized ignition energy and meters gas at the burner inlet to establish proper combustion |
| compatibility | Designed for specific Frigidaire burner assemblies; verify model number and gas type (Natural vs. LP) before replacement |
| Service tip | Inspect electrode gap and orifice for contamination; replace the assembly if ceramic insulation is damaged or electrode is eroded |
Practical diagnosis combines electrical and flow checks: verify the ignitor receives the expected control voltage and visibly confirm a clean, correctly positioned spark or glow while ensuring the orifice is unobstructed. For conversions or repairs, replace the entire assembly with the correctly specified part rather than modifying the orifice in place-using an incorrect orifice size or a misaligned ignitor will alter flame characteristics and can cause incomplete combustion, increased emissions, or safety concerns that require further adjustment of manifold pressure and burner settings by a qualified technician.
How the 316536623 Frigidaire Ignitor/Orifice Assembly Operates Within the Burner Valve and Ignition Circuit
The 316536623 Frigidaire Ignitor/Orifice Assembly is a combined ignitor and precision orifice that mounts at the outlet of the burner valve to provide both gas metering and the local ignition source. The component couples a sealed ignition element (either a spark electrode or a hot surface element depending on the appliance model) with a machined orifice that sets the downstream gas flow rate and pressure drop. Mechanically the assembly is engineered to match the valve spud and the appliance harness: the orifice diameter, thread/seating geometry, and the electrical connector must match the original equipment to maintain proper air-fuel ratio and reliable electrical connection to the control module and valve coil.
During an ignition cycle the oven or range control sequences the valve and ignition circuit so the valve opens while the ignitor is energized; the orifice meters the gas into the burner port and the ignitor provides the energy required to establish a flame. Once the flame is established normal operation may rely on flame sensing (thermocouple, flame rectification, or a sensor in the control) to hold the valve open. In practice this means a failed orifice/ignitor assembly can present as continuous sparking with no flame, delayed ignition, or a weak, lifting flame if the orifice size or alignment is incorrect. Useful technician checks include visual inspection of the electrode gap and orifice bore, verifying secure mechanical seating, and confirming the ignition circuit delivers the expected ignition pulses while the valve coil is energized.
- Common symptoms: continuous sparking with no ignition, delayed flame, uneven burner performance, or gas odor at start-up.
- Practical checks: verify correct part fitment, inspect electrode condition and alignment, confirm valve actuation and ignition pulses, and compare orifice bore to OEM specification.

Diagnostic Indicators: Common Failure symptoms and Measurement Checks for the Ignitor/Orifice Assembly
The 316536623 Frigidaire Ignitor/Orifice Assembly combines a hot-surface ignitor with a matched gas orifice to establish reliable ignition timing and controlled gas flow for a specific range/oven model. In normal operation the ignitor must reach a visible orange-red glow, producing enough current draw to actuate the gas valve and allow the orifice to meter the correct gas volume; mismatch in orifice size, connector type, or ignitor performance will change flame shape, heat output, and ignition delay.Technicians should verify physical compatibility (mounting, connector pins, and orifice orientation) before replacement and inspect the assembly for cracks, erosion, or carbon build-up that can alter electrical resistance or restrict the orifice passage.
- no glow or intermittent glow of the ignitor; oven will not light or has long ignition delay.
- Repeated ignition cycles or clicking without flame, or smell of unburned gas at the burner.
- Yellow/sooty flame or unstable flame indicating incorrect orifice size or partial blockage.
- Measurement checks: continuity/resistance at the ignitor leads, supply voltage at the ignitor connector when the controller calls for heat, and measure current draw while energized to confirm it meets the expected load for valve actuation.
- Visual inspection for physical damage, excessive deposits on the ignitor face, or obstruction inside the orifice bore.
Electrical checks are diagnostic: an open-circuit reading on a multimeter indicates a failed ignitor, while an unusually high cold resistance or low current under live conditions suggests a weak element that will not heat sufficiently to open the gas valve.Voltage present at the connector with the controller calling for heat confirms the control circuit is functioning; absence of voltage points to a control board, safety thermostat, or wiring fault rather than the ignitor itself. Flame observation provides a practical functional check - a steady blue cone centered on the burner indicates correct orifice performance, while a lazy or yellow flame suggests orifice blockage, wrong orifice size, or gas pressure issues that require further measurement by a qualified technician.
| Item | Description |
|---|---|
| Cold resistance (approx.) | Typical range ~30-120 Ω (varies by design); open = failed, high but finite = weak element. |
| Operating supply | Nominal line voltage present at connector when calling for heat ~110-125 VAC; absence implies control/wiring fault. |
| Functional observation | Visible steady glow within seconds and a stable blue flame indicate proper operation; delayed glow or yellow/sooty flame indicate faults. |
Compatibility, Replacement Considerations, and Step‑by‑Step Installation Procedures for Affected Frigidaire Models
The 316536623 Frigidaire Ignitor/Orifice Assembly integrates a high-temperature ignitor element with a matched gas orifice to control ignition timing and fuel flow for specific Frigidaire oven and range burners. technically, the ignitor must reach its designed glow temperature and current draw to allow the gas valve to open; a weak ignitor or an incorrect orifice size will alter valve timing and combustion characteristics, causing delayed ignition, soft flames, or incomplete combustion. Verify the replacement against the appliance model and parts list, confirm connector type, mounting tab orientation, and orifice thread or seating geometry before installation; mismatches in orifice diameter or ignitor electrical characteristics will change flow rate and may require returning to the correct OEM assembly rather than adapting the original unit.*
- Verify model/part match and physical connector before disassembly.
- Shut off gas and electrical supply prior to access and removal.
- Inspect ignitor current draw and orifice for clogging during diagnostics.
- Use manufacturer-approved sealants and torque values on gas fittings.

Start by shutting off both the electrical supply and the gas source,then remove oven racks or access panels to reach the burner box; unfasten mounting screws,disconnect the ignitor harness,and extract the assembly without stressing the ignitor element. Install the new assembly with correct alignment, secure mounting hardware, reconnect the harness, restore gas and power, then perform an operational check: verify ignitor glow, observe ignition timing and flame shape, measure ignitor current against the service specification, and perform a soap-bubble or electronic leak test at all gas joints before returning the appliance to service.
Q&A
What is the 316536623 Frigidaire Ignitor/Orifice Assembly and what does it do?
The 316536623 is a replacement ignitor and orifice assembly used on certain Frigidaire gas ovens/ranges.The ignitor produces the heat or spark required to ignite the gas, while the orifice meters the flow of gas to the burner. Together they control and initiate safe combustion for the oven or burner.
what symptoms indicate this assembly is failing or needs replacement?
Common signs include an oven or burner that takes a long time to light or never lights, a weak or yellow/fluctuating flame, visible damage or cracking on the ignitor, or a persistent gas smell without ignition. You may also notice clicking without ignition on spark systems or an ignitor that does not glow on glow-bar systems.
How can I verify this is the correct replacement part for my appliance?
Check the appliance model number (usually on a tag inside the oven door frame, broiler drawer, or behind a kickplate) and cross-reference it with Frigidaire’s parts lookup or an authorized parts dealer. Do not rely solely on visual similarity - confirm the 316536623 is listed compatible for your exact model.
Can I install the 316536623 myself, and what safety precautions should I take?
Skilled DIYers can replace the assembly, but always turn off the gas supply and disconnect electrical power before beginning.Work in a well-ventilated area, avoid creating sparks, and follow the appliance disassembly instructions. After installation, check all connections and test for gas leaks using an approved leak detector or soapy water. If you’re not confident working with gas and mains electricity, hire a qualified technician.
How do I test the ignitor/orifice assembly to see if it’s faulty before replacing?
Start with a visual inspection for cracks, corrosion, or a clogged orifice. Use a multimeter to check continuity of the ignitor element-an open circuit indicates a failed ignitor. For glow-type ignitors, observe whether the element glows when powered (do this only if installed and powered safely). If the orifice is suspected clogged, do not alter or enlarge it yourself; cleaning might potentially be possible but should be done carefully or by a technician.
Is the 316536623 suitable for both natural gas (NG) and propane (LP) appliances?
Orifice size determines fuel flow, so assemblies may be specific to NG or LP. Some ranges require a dedicated conversion kit (different orifice plus regulator adjustment) to run safely on LP. Do not use the part for the wrong fuel type without confirming compatibility and performing any required conversion per the manufacturer’s instructions or thru a qualified technician.
Can I replace only the ignitor or only the orifice, or do I need to replace the entire assembly?
That depends on how the parts are sold for your model.Some models offer the ignitor and orifice as separate service parts; others are packaged as a combined assembly. Check the parts diagram for your model. Replacing the entire assembly can ensure proper fit and alignment, but if only the ignitor is defective and a separate part is available, replacing just that may be acceptable.
I replaced the assembly but the oven still won’t light – what should I check next?
If replacement didn’t fix the problem,verify the gas supply is on and reaching the appliance,check the burner valve and safety gas valve operation,inspect wiring and connectors to the ignitor/ignition module,and look for error codes on the control board. On glow ignitors, ensure the ignitor draws the required current (if you can measure safely) and the ignitor reaches operating temperature. When in doubt, contact a qualified appliance technician to avoid unsafe gas or electrical conditions.
