316536602 Frigidaire Oven Ignitor/Orifice Assembly is a combined ignition and gas metering component used in Frigidaire gas ovens; the assembly typically integrates a hot-surface ignitor element with a matched gas orifice and mounting hardware that together form the burner’s ignition and flow-control interface. As a discrete replaceable part, it mounts at the oven burner/shroud and provides both the electrical heating element required to initiate combustion and the precisely sized passage that governs gas delivery to the burner.
Inside the appliance the ignitor/orifice assembly participates directly in the combustion subsystem and interfaces with the oven control and gas delivery systems. The ignitor heats to a specified temperature (or presents a specific electrical characteristic) that permits the oven’s gas safety valve to open; the orifice then meters the volume and velocity of gas into the burner ports. The assembly therefore interacts with the gas manifold, safety valves/solenoids, the oven control/relay circuitry and the burner head, and its condition affects flame establishment, stability and heat output.
this article explains the part’s functional design and expected operating behavior, outlines compatibility factors (mechanical fit, connector type, and orifice sizing for natural gas vs. LP), and summarizes common failure symptoms such as no ignition, extended ignition delay, weak or uneven flame, and relevant control error indicators. It also covers basic troubleshooting checks a technician can use (visual inspection, resistance and voltage measurements at the ignitor, confirmation of correct orifice size and unobstructed gas paths), and replacement considerations including correct part selection, sealing and mounting, electrical connections, and safety precautions (shutting off power and gas, leak testing) to ensure safe restoration of oven operation.

Function and Role of the Oven Ignitor/Orifice in Gas Flow Regulation and Safe Ignition
The 316536602 Frigidaire Oven Ignitor/Orifice assembly combines a hot-surface ignitor element with a matched gas orifice to control safe ignition and steady gas flow. The ignitor heats to a specific resistance and current draw, which in turn allows the oven safety valve to open; the orifice meters the gas flow at the valve outlet so the burner receives the correct volumetric flow for the appliance’s manifold pressure. In practice this paired component determines ignition timing, flame stability, and the appliance’s delivered heat output, so replacements should match electrical connector type, mounting geometry, and orifice sizing for the appliance’s fuel type (natural gas or LP) and pressure setting.
- Common failure symptoms: no glow or weak glow from the ignitor, delayed or absent ignition, or a persistent gas odor prior to combustion.
- Behavior notes: ignitor resistance falls as it heats; the gas valve requires a minimum current to open, so a degraded ignitor can prevent valve actuation despite visible heating.
- Compatibility checklist: verify part number, connector pins, mounting tabs, and orifice designation before installation; manifold pressure testing confirms correct flow after replacement.

|---|---|
| Ignitor function | heats to lower resistance and permit required current to energize the oven safety valve coil. |
| Orifice role | restricts and meters gas flow to set burner heat output appropriate for the manifold pressure and fuel type. |
Technicians diagnosing the assembly should measure ignitor resistance and operational current with the appliance’s power applied (observing all safety precautions) and confirm gas valve actuation at the appropriate current threshold; bench resistance alone can be misleading as a glowing element must reach operating temperature to draw rated current. After replacement, perform a visual flame check and, if available, measure manifold pressure and conduct a combustion check to ensure the orifice and ignitor combination produce stable flame geometry and correct heat rise for the specific Frigidaire model.
How the 316536602 Frigidaire Oven Ignitor/Orifice Assembly Operates Within Frigidaire Gas Oven Systems
The 316536602 Frigidaire Oven Ignitor/Orifice Assembly combines a hot-surface ignitor element with a matched gas orifice so the ignition and gas metering functions behave as a single, calibrated unit inside compatible Frigidaire gas ovens. when the oven control requests heat,it energizes the ignitor; the ignitor must reach a specified incandescent temperature and electrical draw so the oven’s safety circuit will permit the gas valve to open. Gas then flows through the orifice at the engineered pressure and flow rate to the burner port where the glowing ignitor lights the mixture. As the ignitor and orifice are paired, installing the correct assembly preserves the intended air/gas mixture and timing characteristics set by the factory, avoiding improper flame shape or safety lockouts caused by mismatched components.
In practice,technicians evaluate this assembly by observing the ignition sequence and flame quality: a healthy unit glows steadily,starts the gas flow within the control’s permitted interval,and yields an even,blue burner flame; a weak or failing ignitor produces delayed ignition,repeated safety timeouts,or yellowish flames that indicate incomplete combustion. Troubleshooting typically includes a visual glow check,confirming harness continuity and voltage at call-for-heat,and inspecting the orifice and burner ports for blockages or damage. Replace the assembly rather than onyl the ignitor when orifice condition or compatibility is uncertain to restore correct gas metering and system behavior.
- Common symptoms: long ignition delay, repeated lockouts, uneven or yellow-tipped flames.
- Service checks: visual glow, voltage during call for heat, harness and mount integrity, flame pattern after replacement.
- Installation note: secure mounting and correct orientation of the orifice are required for proper flame and sealing.

Common Failure Symptoms and Measurable Diagnostic Criteria for Ignitor/Orifice Malfunction
The 316536602 frigidaire Oven ignitor/Orifice Assembly combines the hot-surface ignitor and matched gas orifice so the ignitor can heat to the correct temperature and draw sufficient current to lift the gas valve for reliable ignition. When the ignitor element ages, its electrical characteristics change: cold resistance will shift and operating current may drop below the valve pull-in requirement. Thes electrical changes cause measurable symptoms such as no glow, slow or weak glow, extended glow-to-valve-open time, or intermittent ignition. Technicians should verify presence of 120 VAC at the connector, check ignitor continuity and cold resistance with a multimeter, and measure operating current with a clamp meter while observing the glow time under live conditions to determine if the ignitor or orifice is the limiting factor.
- No glow or open circuit – multimeter reads OL/infinite resistance or no 120 VAC at connector.
- Weak glow or long pre-ignition time – ignitor reaches dim orange only and valve does not open within typical time; clamp meter shows reduced current draw.
- Poor flame shape or yellow tipping – orifice restriction or wrong orifice size (LP vs natural) affecting flame; compare to expected blue mantle and flame height.
- Intermittent ignition or repeated retries – inconsistent voltage/current or partial blockage causing unstable manifold pressure.
Practical diagnosis pairs electrical measurement with flame observation and pressure checks: confirm the ignitor draws sufficient amperage to satisfy the oven valve pull-in spec and that the orifice matches the appliance’s gas type and manifold pressure. Replacing the ignitor alone can restore current draw, but a clogged or incorrectly sized orifice will still produce weak flames, so inspecting and cleaning or replacing the orifice is frequently enough required. For safety and repeatability, document measured resistance, operating current, and glow-to-valve-open time and compare those values to the appliance service specification before replacing components; matching the ignitor and orifice as an assembly preserves the designed thermal and flow relationship for consistent operation.
| Item | Description |
|---|---|
| Ignitor cold resistance | Typical range for similar HSI elements: approximately 30-200 Ω (measure with power disconnected). |
| Operating current | Typical operating current range: approximately 2.5-3.6 A at 120 VAC; below this indicates reduced heating capability. |
| Glow-to-valve-open time | Expected full glow and valve opening within ~30-45 seconds; considerably longer indicates degradation. |
| Flame characteristics | Blue, stable flame at correct height; yellow tipping, lifting, or short flame suggests orifice restriction or incorrect sizing. |
Compatibility, Replacement Procedures and Installation Requirements for the 316536602 Assembly
The 316536602 Frigidaire Oven Ignitor/Orifice Assembly integrates the electrical ignitor element and the gas orifice into a single serviceable unit; its role is to reliably initiate and sustain a stable burner flame and to draw the correct holding current through the gas valve. Functionally, the ignitor must reach a specified current (measured as milliamp draw) and the orifice must match the oven’s manifold pressure and burner geometry to produce the designed flame pattern. Technicians should verify the assembly’s electrical characteristics (cold resistance and operational milliamp draw) and the orifice size against the oven’s service specifications-mismatched resistance or undersized/oversized orifices produce weak flames, delayed ignition, or safety shutoffs rather than issues with control boards or thermostats.
Replacement and installation focus on safety, fit, and verifying performance after service. Typical field procedure includes isolating electrical power and gas, observing correct mounting orientation and gasket sealing to prevent air leaks, and confirming the ignitor reaches rated current and the flame exhibits a stable, even blue envelope across the burner after installation. Practical checks after replacement include observing ignition time, steady current draw with a clamp-on milliammeter or multimeter in series, and absence of gas smell or delayed ignition; if irregularities persist, re-check manifold pressure, wiring continuity, and orifice part number before replacing additional components.
- Pre-replacement checks: verify model compatibility, confirm power/gas isolation, measure ignitor resistance and expected milliamp draw.
- Installation steps: secure mounting screws, replace gaskets, reconnect wiring, restore power and gas, observe ignition sequence and flame quality.
- Post-install tests: measure current under load, inspect flame shape, and check for gas leaks with a soap solution or approved detector.
| Item | Description |
|---|---|
| Ignitor resistance | Typically low ohms when cold; refer to service sheet for exact value and acceptable range |
| Operational current | Measured in milliamps; must reach the valve’s pull-in rating to open reliably |
| Orifice identification | Stamped orifice size must match appliance specification for correct BTU delivery |
Q&A
What is the 316536602 Frigidaire Oven Ignitor/Orifice Assembly and what does it do?
The 316536602 assembly is a replacement component for certain Frigidaire/Frigidaire Gallery ovens that combines the oven ignitor (glow bar or spark device depending on model) and the gas orifice/mounting hardware.The ignitor creates the heat or spark required to ignite the gas, and the orifice controls the gas flow into the burner. Together they initiate and sustain the burner flame for the oven.
How do I know if the ignitor/orifice assembly is the problem when my oven won’t light?
Common signs include the ignitor not glowing, a very weak or slow-to-glow ignitor, long burn/ignite delays (oven trying to light for a long time), or the burner not producing a stable flame after it glows. You may also see error codes on electronic models. Visually inspect for cracks, breaks, or heavy carbon buildup on the ignitor and orifice.For a more definitive diagnosis, a technician will check for continuity on the ignitor and measure current draw during start-up; if the ignitor fails to reach the required current or does not glow properly, it should be replaced.
Is the 316536602 part compatible with my Frigidaire oven model?
Compatibility depends on the oven model and whether your oven is set up for natural gas or LP (propane). Always verify compatibility by matching the appliance model number with Frigidaire parts listings or the OEM parts diagram. The orifice size is gas-type specific, so replacing with the correct version (natural vs LP) is essential. If in doubt, provide your oven’s model number to a parts dealer or check the manufacturer’s parts lookup.
Can I install the 316536602 myself, and what safety steps should I take?
Many handy homeowners can perform the replacement, but you must follow strict safety steps: disconnect electrical power to the oven, shut off the gas supply, and allow components to cool. Use correct tools (screwdrivers, nut drivers, wrench) and keep track of mounting screws and wiring. After installation, check for gas leaks and proper ignition. If you are not agreeable working with gas or mains electricity,hire a qualified appliance technician-gas work can be hazardous if done improperly.
What tools and tests are useful when replacing or diagnosing this assembly?
useful tools include a multimeter (to check continuity/resistance), an ammeter or clamp meter (to measure ignitor current during operation), screwdrivers or nut drivers for fasteners, and a wrench for orifice fittings. Tests include a continuity check of the ignitor (open circuit indicates failure) and a live-current test during a light cycle (a weak or low-current draw is a common failure sign). Also inspect the orifice and burner ports for clogging or debris that can affect flame.
How long does replacement take and what is a typical cost?
replacement time for someone experienced is often 30-60 minutes, including shutdown and reassembly. For a first-time DIYer it may take longer. The cost for the part varies depending on seller and whether you buy OEM or aftermarket-check current listings-but budget also for possible technician labor if you hire a pro. Prices and labor rates vary by region and vendor.
After I replace the assembly the oven still won’t light – what else should I check?
If the new ignitor/orifice assembly doesn’t solve the problem, check the gas safety valve (the valve sometimes fails and will not open even with a good ignitor), wiring and connectors for damage or loose connections, the oven control board/relay, and thermostat or temperature sensor. Also confirm the correct orifice type for your gas (natural vs LP) and that there are no obstructions in the burner manifold. If these checks don’t identify the issue, call a qualified appliance technician.
Can I convert this assembly between natural gas and LP (propane)?
Orifice size and flow differ between natural gas and LP. Some assemblies are sold specifically for one gas type; converting generally requires changing to the correctly sized orifice and sometimes adjusting other components. Do not attempt to operate an assembly with the wrong orifice installed. Gas conversion should follow the manufacturer’s instructions and local codes-if you need a conversion, have it done by a qualified technician and obtain any required conversion jets or kits from the manufacturer or an authorized parts supplier.
