316536610 Frigidaire Ignitor/Orifice Assembly is a combined ignition adn fuel metering component used on Frigidaire gas appliances. The assembly pairs an ignition element (spark electrode or hot-surface igniter) wiht a precisely sized orifice that meters gas flow to a specific burner. It is a mechanical and electrical subassembly that mounts at the burner or manifold and provides the interface between the appliance’s gas delivery system and the ignition circuit.
Inside the appliance the ignitor/orifice assembly performs two tightly coupled functions: initiating combustion and controlling the quantity of gas delivered to the burner. The ignition element receives switching voltage from the appliance control to create a spark or glowing surface at the correct time, while the orifice creates the pressure drop and flow restriction that determine flame size and shape for a given manifold pressure. The part therefore interacts directly with the gas valve and regulator/manifold, the control board and ignition circuit, and downstream flame-sensing or safety devices; its condition and specification affect heat output, combustion stability, and safe shutoff behavior.
in this article you will find technical information to help technicians, engineers, and appliance owners understand the 316536610 assembly: details of its function and typical installation locations, compatibility considerations (including gas type and orifice sizing), common failure symptoms to recognize, and practical troubleshooting checks to isolate electrical versus fuel-flow faults. The article will also cover replacement considerations – matching orifice size and mounting,electrical connector and sealing requirements,and safety precautions to follow when servicing the gas and ignition circuits – so readers can make informed diagnostic and repair decisions without relying on marketing language or unsupported claims.

Function and Role of the Ignitor/Orifice Assembly in Gas burner Operation
The 316536610 Frigidaire Ignitor/Orifice Assembly combines the gas metering function of an orifice with an electrical ignitor to initiate combustion at a burner. In operation, gas is delivered through the orifice at a controlled flow rate while the ignitor produces a spark (or a heated surface, depending on the model) at the correct position relative to the gas jet.Proper alignment and spacing between the ignitor electrode and the orifice are critical: the ignitor must energize at the moment the correct volume of gas is present so the mixture lights cleanly and consistently. Malfunctions in either component change the ignition behavior-examples include repeated clicking with no light (ignitor fault), delayed ignition, or a weak, yellow, or lifted flame (orifice sizing or air/fuel ratio issues).
Compatibility and practical service considerations center on gas type, orifice size, and mounting configuration. The orifice diameter is sized for natural gas or liquid propane and is not interchangeable without changing flow characteristics and manifold pressure settings; technicians should verify the appliance model and stamped orifice size before replacing the assembly. Typical diagnostic and setup checks include verifying the electrode gap and secure mounting, confirming the orifice threads and pressure rating match the range, and observing flame shape under normal manifold pressure. Key functional points and common service observations are listed below to aid troubleshooting.
- Function: orifice meters gas flow; ignitor provides the ignition energy at the gas jet.
- Behavioral signs: clicking without ignition, delayed light, yellow flame, or uneven burner flame.
- Compatibility: match orifice size to gas type (NG vs LP) and confirm the assembly’s mounting pattern for the model.

How the 316536610 Frigidaire Ignitor/Orifice Assembly Interfaces with valve, Control, and Flame Systems
The 316536610 frigidaire Ignitor/Orifice Assembly connects mechanically, pneumatically, and electrically to the range’s valve and control systems to initiate and sustain combustion. Mechanically the assembly indexes into the burner manifold so the orifice aligns with the valve outlet and the ignitor tip sits in the correct position relative to the burner ports; improper seating alters mixture and flame shape. Electrically the ignitor provides the energy required to create ignition - either by delivering timed sparks or by heating a hot-surface element depending on the appliance design - while the control board sequences the gas valve and monitors the ignition event. The valve responds to a low-voltage open command from the control; the orifice size and manifold pressure together determine delivered BTU so compatibility with the model-specific pressure rating and orifice specification is required when replacing the part.
- Delayed ignition or repeated valve cycling - ignitor misalignment or slow heat-up.
- Yellow or lifting flame – incorrect orifice size, incorrect air shutter, or low manifold pressure.
- No spark/no heat at ignitor – open circuit in ignitor leads or incompatible connector to control board.
- control lockout after failed ignition attempts – diagnostic symptom pointing to flame-sensing or valve timing faults.
Flame sensing and safety interlocks are integral to how the assembly interfaces with the control and valve. The control expects a defined ignition sequence: call for heat, energize ignitor, open gas valve for a controlled duration, and then verify flame presence via an ionization/rectification signal or thermocouple feedback before maintaining valve hold. In practice, technicians verify compatibility by matching the assembly’s electrical connector, orifice designation and mounting geometry to the appliance schematic, measure ignitor resistance or spark output, and confirm manifold pressure under load. Replacing the 316536610 frigidaire Ignitor/Orifice Assembly with a mismatched orifice or non-equivalent ignitor type can produce delayed ignition, inefficient combustion, or trigger safety shutdowns; during service, documenting valve timing and flame-sense signals helps isolate whether the fault originates in the ignitor/orifice, the valve, or the control electronics.
| Item | Description |
|---|---|
| Orifice role | Restricts and meters gas flow to match burner BTU and manifold pressure. |
| Ignitor role | Provides energy to initiate combustion (spark or hot surface) and must be positioned for consistent ignition. |
| Control interface | Low-voltage commands and timing signals coordinate valve opening and ignitor operation; connectors must match harness. |
| Flame sensing | Ionization/rectification or thermocouple feedback confirms flame presence before the control holds the valve open. |
Common Failure Symptoms and Diagnostic Indicators of Ignitor/Orifice assembly Malfunction
the 316536610 Frigidaire Ignitor/Orifice Assembly combines the heating or spark-generating ignitor with a matched gas orifice to initiate and regulate combustion on compatible frigidaire gas ranges and ovens. The ignitor must reach a specific temperature or produce a consistent spark to allow the gas valve to open and the burner to light, while the orifice meters fuel flow to produce the correct flame shape and heat output. When the ignitor degrades, its electrical characteristics change (higher resistance or reduced current draw) and the downstream gas flow from the orifice can produce weak, elongated, or sooty flames if the orifice is clogged or the wrong size for the manifold, leading to temperature control problems and longer bake times.
Diagnosing a malfunctioning assembly relies on a combination of observation and measurement: perform a careful visual inspection for a cracked or glazed ignitor and deposits in the orifice, then use electrical checks to verify continuity and measure voltage at the harness while initiating a call for heat. Symptoms such as long ignition delay, repeated sparking without sustained flame, persistent yellow or sooty flame, or the oven failing to reach set temperature point toward either a weak ignitor or an orifice issue; a persistent gas odor or continuous gas flow without ignition requires immediate shutoff and professional service. Common diagnostic steps include verifying line voltage during ignition, measuring ignitor resistance against the service specification, and comparing flame appearance to a known-good burner after cleaning or swapping assemblies.
- Long ignition delay or repeated attempts to light
- Yellow, flickering, or sooty flame instead of steady blue
- Oven failing to reach or maintain set temperature
- Visible cracks, glaze, or no continuity in ignitor element
- reduced current draw or higher-than-expected resistance on electrical test
- Clogged, damaged, or incorrectly sized orifice affecting flame pattern
| Item | Description |
|---|---|
| Ignitor resistance | Measure cold resistance and compare to specification; elevated resistance indicates degradation. |
| Ignition delay | Time from call for heat to sustained flame; significantly longer than normal indicates weak ignitor or valve issue. |
| Flame color/pattern | Blue and steady indicates correct combustion; yellow or lifting flame suggests orifice blockage or improper air/fuel ratio. |
compatibility, Replacement Considerations, and Step‑by‑Step Installation Checklist
The 316536610 Frigidaire Ignitor/Orifice Assembly combines the ignition element and the fixed gas metering orifice into a single service replaceable unit that controls both the initial energy to light the burner and the volume of gas delivered at the burner port. The ignitor provides the spark or hot-surface ignition source and must be positioned and insulated correctly relative to the orifice for reliable ignition; the orifice diameter determines primary gas flow and flame geometry, so using the correct orifice for the appliance’s gas type (natural or LP) and manifold pressure is critical. In practical terms, a direct replacement preserves original flame characteristics and ignition timing; installing an orifice sized for the wrong fuel or a misaligned ignitor commonly results in delayed ignition, weak or sooting flames, or safety shutoff events.
- Safety and prep: Shut off gas and electrical power before beginning work.
- Document and label electrical connections; remove burner head and retaining screws to access the assembly.
- Compare the new part visually to the old one (orifice size, mounting orientation, connector type) before installation.
- Install using the appliance manufacturer’s recommended sealant/torque for gas fittings; secure the ignitor so the gap/orientation matches the factory position.
- Perform a leak test on gas fittings and a functional test of ignition sequence and flame after reassembly.
Compatibility checks focus on physical fit, connector type, and gas specification rather than brand alone: confirm the appliance model/serial and that the replacement matches the original orifice size and electrical connector. Technicians should inspect the ignitor for visible cracks, ceramic damage, or loose electrodes and verify continuity or expected resistance values per the service manual before installation; an open ignitor or visible electrode erosion warrants replacement. If post-install tests show persistent ignition problems, expand troubleshooting to manifold pressure, regulator setting, and valve performance, since a properly sized orifice and correctly mounted ignitor are necessary but not sufficient for correct operation in the presence of upstream pressure or valve faults.
| Item | Description |
|---|---|
| Compatible models | Verify appliance model/serial and cross-reference part number; physical match is required. |
| Gas type | Orifice size and labeling must match Natural or LP service; conversions require matched orifice and regulator adjustments. |
| Common symptoms | delayed ignition, weak or yellow flames, or repeated safety lockouts indicate orifice/ignitor mismatch or failure. |
Q&A
What is the 316536610 Frigidaire Ignitor/orifice Assembly?
The 316536610 is an OEM ignitor and burner orifice assembly used on some Frigidaire gas ranges and ovens. It contains the ignition component that lights the gas and the orifice that meters the gas flow to the burner. Together they control and initiate the flame for a specific burner or oven burner tube.
What symptoms indicate the ignitor/orifice assembly is failing?
Common symptoms include a burner or oven that will not light, a delayed ignition (clicking or sparking repeatedly before a flame appears), weak or yellowing flame, or continuous clicking with no ignition. Visible damage, heavy carbon buildup, or a cracked insulator on the ignitor are also signs the assembly should be replaced.
how can I test the assembly to confirm it’s bad?
Start with a visual inspection for cracks, corrosion, or heavy carbon. For ignitors that are hot-surface type, check for continuity with a multimeter (no continuity usually means a failed ignitor). For spark ignitors,you can check for a visible spark when attempting ignition (power on,gas off test not recommended). Also verify gas supply and valve operation because a bad valve or gas line issue can mimic ignitor problems.
Can I clean the orifice or ignitor rather of replacing it?
Minor carbon or grease buildup can sometimes be cleaned from the orifice or ignitor with a soft brush and compressed air. Do not use wire or drills to enlarge the orifice-altering the orifice size will change burner performance and can be unsafe. If the orifice is damaged, clogged beyond cleaning, or the ignitor is cracked or has no continuity, replacement is recommended.
How do I replace the 316536610 assembly safely?
Turn off the gas supply and unplug or switch off electrical power to the appliance. Remove the burner grate and cap (or oven access panel for oven ignitors), disconnect the ignitor wiring harness, and unthread the orifice using the correct-size wrench. Install the new assembly, reconnect wiring, restore power and gas, and perform a leak check. If you are not comfortable working with gas connections or electrical components, hire a qualified technician.
what tools and materials do I need for the replacement?
Typical tools: adjustable wrench or correct-size open-end wrench for the orifice, nut drivers or screwdrivers for panels, pliers, a multimeter for testing, and a non-corrosive soap solution or approved gas leak detector for checking connections. Have replacement gaskets or sealant if required by the installation instructions, and always follow the appliance manufacturer’s guidelines.
How do I check for gas leaks after installing the new assembly?
After restoring the gas supply (but before lighting the burner), brush a mixture of mild soap and water over the connection points and watch for bubbles, which indicate a leak. You can also use a commercial gas leak detector. Never use an open flame to check for leaks. If you detect a leak, turn off the gas promptly and tighten connections or call a professional.
How do I know if this part is compatible with my Frigidaire appliance?
Verify compatibility by checking your appliance model number (usually on a tag behind the oven door, on the frame, or on the back of the range) and cross-referencing it with Frigidaire parts lists or a reputable parts supplier. Do not rely solely on visual similarity-confirm the OEM part number or approved cross-reference to ensure proper fit and safe operation.
