316536602 Frigidaire Oven Ignitor/Orifice Assembly is a combined gas ignition and metering component used in Frigidaire gas ovens and ranges. The assembly typically integrates a hot surface or glow ignitor with a matched orifice (jet) that meters gas flow to a specific burner; it is a field‑replaceable service part designed to sit at the burner port and provide the heat and gas calibration necessary for reliable ignition and combustion.
Inside the appliance the ignitor portion heats to a visible glow to initiate gas flow and allow the safety gas valve to open; the orifice portion precisely controls the gas volume delivered to the burner for the intended BTU output. The assembly interfaces mechanically and electrically with the oven burner tube, gas manifold/valve, and the oven control/safety circuits, and its condition directly affects flame establishment, flame shape and stability, and temperature control response. Proper installation, orientation and selection of the correct orifice size (natural gas versus propane/LP) are important for safe, efficient combustion and to avoid issues with incomplete combustion or regulator/valve cycling.

Function and Role of the Oven Ignitor/orifice Assembly in Gas Delivery and Ignition Control
the 316536602 Frigidaire Oven Ignitor/Orifice Assembly integrates a hot-surface ignitor element with a matched gas orifice to control both the timing of ignition and the volume of gas delivered to the burner. When a bake or broil call is made, the control applies voltage to the ignitor so it heats to an incandescent temperature; the resulting current draw is used by the oven safety valve circuit as the permissive signal to open the valve. Once the valve opens, the orifice meters the gas flow to produce the intended flame geometry and heat output for that specific Frigidaire model. The matched assembly ensures the ignitor’s electrical characteristics and the orifice’s flow rate are coordinated, which is necessary for consistent ignition behavior and correct oven BTU delivery.
failures or mismatches in this assembly produce predictable symptoms useful for diagnosis and replacement decisions: delayed or repeated ignition attempts, failure to reach set temperature, yellow or sooty flames, or a persistent glow without ignition are common indicators of a weak ignitor or wrong orifice size. Compatibility must be checked against gas type (natural vs. LP) and model-specific mounting and connector details; swapping an ignitor without the correct orifice can under- or over-fire the burner and effect combustion safety.Technicians typically confirm functionality by visual flame inspection, verifying correct mechanical fit and connector integrity, and comparing measured ignitor electrical behavior to the OEM service data before installing the replacement assembly. For safe service, isolate power and gas before removal and follow the appliance manufacturer’s procedures.
- Primary functions: heat the ignitor to actuate the gas valve and meter gas flow through the orifice.
- Common symptoms of failure: long glow time, no ignition, inconsistent temperatures, sooting.
- Compatibility checks: gas type, connector type, mounting orientation, and OEM specifications.
- Service practise: verify electrical behavior and physical fit prior to replacement; follow safety isolation procedures.

How the 316536602 Frigidaire Oven Ignitor/orifice Assembly Works Inside the Appliance
The 316536602 Frigidaire Oven Ignitor/Orifice Assembly combines a hot-surface ignitor with a sized gas orifice and mounting bracket so the ignition element and the gas jet are correctly positioned relative to the bake burner. In operation the ignitor heats to a visible orange glow and its electrical resistance drops; this change allows the oven’s control circuit and safety valve to pull the required current and release gas through the orifice. The orifice itself is a fixed aperture calibrated to the appliance’s design pressure and burner geometry, so the assembly as a unit controls both the timing of ignition and the delivered fuel flow that produces a stable, even flame across the burner ports.
- Behavior: ignitor must glow continuously until the valve opens; orifice profiles determine flame size and combustion quality.
- Common failure modes: no glow (open ignitor), slow-to-glow (reduced current draw), orifice blockage or improper sizing causing weak or yellow flame.
- Compatibility considerations: replacement should match part number, connector type, mounting orientation, and orifice size for model-specific gas pressure and burner design.
Technicians diagnose the assembly by visual inspection, resistance and current measurements, and by observing flame characteristics during ignition. If the ignitor glows but gas does not flow, the technician will suspect orifice blockage or a valve issue; if gas flows but the ignitor does not light reliably, the ignitor element or its wiring/connector are the likely faults. When replacing the assembly, use the matching 316536602 unit or a documented equivalent to preserve orifice sizing and mounting alignment; verify proper grounding, secure fasteners, and a leak-free gas connection before returning the oven to service.

Common Failure Symptoms and Diagnostic Indicators of Ignitor/Orifice Assembly Faults
The 316536602 Frigidaire Oven Ignitor/Orifice Assembly combines the hot‑surface ignitor and the matched gas orifice into a single replacement unit that controls both ignition and the initial gas flow characteristic for compatible Frigidaire ovens. In normal operation the ignitor draws current, heats to emit sufficient radiant energy to open the oven safety valve, and the orifice meters the gas volume to produce a stable pilot/flame pattern. Failure of either element alters the ignition sequence: a weak or slowly heating ignitor can allow the safety valve to time out without lighting, while a partially blocked or incorrectly sized orifice produces a weak or unstable flame even if the ignitor glows. Technicians should verify model compatibility and confirm whether the assembly is a factory specification or an aftermarket equivalent before diagnosis or replacement,as orifice sizing and connector types vary across serial groups and affect flame geometry and BTU delivery.
Common diagnostic indicators are measurable and observable: extended ignition delay, ignitor that glows but gas does not ignite, uneven flame distribution, or persistent failure to reach set temperature. practical checks include a visual inspection for cracked or darkened ignitor elements, verifying connector integrity, comparing ignitor current draw to the service manual specification, and inspecting the orifice for debris or deformation. Always shut off gas and electrical supply before performing continuity or resistance checks. replacing the entire 316536602 assembly is frequently enough the most efficient corrective action when tests show low current to the ignitor or visible orifice restriction; in other cases, correcting wiring faults or cleaning the pilot path can restore proper operation without replacement.
- Ignitor glows but no ignition – suggests weak ignitor heating or blocked/nozzle flow.
- Long ignition time or frequent timeout – indicates degrading ignitor current or marginal heating.
- Uneven or low flame – points to orifice restriction, incorrect orifice size, or gas pressure issues.
- No glow at all – likely open ignitor circuit, failed element, or wiring/connective failure.
| Item | Description |
|---|---|
| Ignitor glow without flame | Ignitor produces heat but gas flow is restricted or safety valve fails to open fully; inspect orifice and valve operation. |
| slow warm‑up / long preheat | Marginal current through the ignitor causes extended heat‑up time; compare measured current/resistance to service specs. |
| Irregular flame pattern | Orifice contamination, incorrect orifice, or improper burner alignment affecting combustion stability and performance. |
Compatibility, Replacement Considerations, installation Steps and Troubleshooting Procedures
The 316536602 Frigidaire Oven Ignitor/Orifice Assembly is a combined hot-surface ignitor and matched gas orifice used on a range of Frigidaire gas ovens. The ignitor portion provides the electrical heating element that draws current and produces the heat necessary to signal the oven gas valve to open; the orifice meters the gas to the burner and must match the oven’s design BTU and gas type (natural or LP). Compatibility is persistent by the assembly’s mounting pattern, connector type, orifice size (orifice drill/diameter), and the oven’s control method - replacing with a unit that differs in any of thes parameters can cause poor ignition, incorrect flame shaping, or unsafe combustion. Always cross-reference the oven model and the OEM part number before ordering, and confirm whether the orifice is sized for natural gas or requires conversion for LP service.
Replacement and troubleshooting follow standard service procedures: disconnect electrical power and isolate the gas supply, remove the burner access panel, check for visible damage (cracked ceramic, broken leads), measure ignitor resistance and observe current draw during attempted ignition, inspect the orifice for obstruction, and confirm correct mounting and gasket alignment when installing the replacement. Common symptoms that indicate this assembly may be failing include extended glow time before the valve opens, no ignition, weak or yellow flame, or intermittent burner operation; resolving these usually requires verifying the ignitor’s electrical characteristics and swapping the orifice only if the gas type or required BTU differs. Fast checklist for safe and effective replacement and diagnosis is shown below.
- Safety first: shut off power and gas, then depressurize and ventilate the area.
- visual inspection: check ignitor ceramic and lead integrity; clear any debris from the orifice.
- Electrical checks: measure cold resistance and, where possible, measure hot current during an ignition attempt per service manual.
- Install: fit assembly to OEM mounting, tighten fasteners to spec, reconnect harness, restore gas and power, and perform a leak and combustion check.
