316536602 Frigidaire Oven Ignitor/Orifice Assembly is a replacement service part that combines a hot surface ignitor element with its associated orifice and mounting hardware used on gas ovens. The assembly typically includes the ceramic-backed ignitor (glow bar), a metal mounting bracket that positions the ignitor relative to the burner tubeand the orifice or orifice holder that meters and directs gas flow into the burner.
Within the appliance the ignitor/orifice assembly performs two complementary functions: the ignitor heats to a high temperature to ignite the gasand the orifice determines the amount and pattern of gas delivered to the burner for proper combustion. It interfaces directly with the oven’s gas valve and burner tube and is monitored or driven by the range control/ignition circuit; its behavior therefore affects ignition timing, flame stability, and the safety interlocks that prevent gas flow when ignition conditions are not met.
In this article readers will find a technical overview of how the 316536602 assembly operates, specification details relevant to technicians (typical resistance/current characteristics and orifice sizing), model compatibility considerations, common failure symptoms (no ignition, delayed ignition, weak or uneven flame, or intermittent operation), diagnostics to isolate ignitor versus gas flow issuesand practical replacement considerations such as correct alignment, mountingand verification procedures.The focus is on providing the details needed to assess, test, and replace the part in a safe and technically sound manner.

Function and Role of the Part in Oven Ignition and Gas Regulation
The 316536602 Frigidaire Oven Ignitor/Orifice Assembly combines a hot-surface ignitor with a precisely sized gas orifice to perform two interdependent functions: generate the thermal energy required to ignite burner gas and limit the volumetric flow so the burner receives the correct fuel/air ratio. The ignitor element must reach its operating temperature and draw the expected current so the oven’s gas valve will energize; together the orifice produces the pressure drop that sets the burner’s BTU delivery and flame shape. Because the orifice size and mounting interface are specific to oven models and to natural gas vs. propane service, the assembly must match the appliance’s model number, valve port geometryand fuel type to maintain safe, stable combustion and proper thermostat control.
- Common symptoms of a failing assembly: long ignition delay, weak or lifting flame, yellow/sooting flameor complete failure to light.
- Compatibility items to check: gas type (NG/LP), valve connection thread/port, electrical connector styleand mounting gasket or bracket orientation.
- Practical checks: confirm the ignitor visibly glows, inspect the orifice for debris or corrosionand verify flame pattern after replacement or conversion.
In practise a technician will replace the complete assembly when ignition problems coincide with poor flame characteristics, because a marginal ignitor can cause slow valve operation while a mismatched or plugged orifice affects combustion stability.Such as, an oven that glows but does not light reliably often indicates an ignitor that cannot reach required thermal output or an orifice partially obstructed; swapping only one component can leave the system out of specification. Correct installation and verifying the part number against the appliance’s service manual ensure the assembly restores designed flow rates and reliable ignition without creating unsafe gas flow or inefficient combustion.

How the 316536602 Frigidaire Oven Ignitor/Orifice Assembly Works Inside the Appliance
The 316536602 Frigidaire Oven Ignitor/Orifice Assembly combines a hot-surface ignitor and a precision gas orifice into a single service component that both produces the ignition heat and meters the gas supply to the bake burner.When the oven controller calls for heat it applies mains voltage (typically 120 VAC in North American models) to the ignitor; as the ignitor element reaches its operating temperature it allows the series current to reach the gas safety valve coils so the valve can open. Gas then flows through the matched orifice into the burner port and contacts the red‑hot ignitor surface, producing a stable flame without a spark. In practice, a weak ignitor may glow yet fail to reach the required temperature or current draw, preventing the valve from opening and causing long ignition delays, no heator erratic cycling.
- Common diagnostic indicators: prolonged glow before ignition,no flame despite glowing ignitor,or yellow/sooty flame pointing to incorrect orifice or pressure.
- Functional considerations: the ignitor must provide sufficient current for the safety valve; the orifice must match the fuel type and line pressure for correct flame shape and heat output.
| Item | Description |
|---|---|
| Ignitor type | Hot surface ignitor (HSI) that heats to ignite gas and participates in the valve current circuit |
| Electrical | Fed by oven control; designed for typical line voltage with specified current draw required to actuate gas valve |
| Gas compatibility | Available in natural gas or LP orifice sizes; correct match required for safe combustion |
Technicians replacing the 316536602 Frigidaire Oven Ignitor/Orifice Assembly should verify both the electrical connector and the orifice size for the model and fuel type before installation. Mounting orientation and the integrity of the burner ports affect flame propagation; a partially clogged orifice or damaged ignitor element will alter the air-fuel mixture and cause low heat or incomplete combustion. For troubleshooting, measure the ignitor’s current draw and inspect the orifice opening: an ignitor that fails to draw its rated current or an orifice that produces an irregular, liftingor yellow flame indicates the specific subcomponent (ignitor or orifice) needs replacement or the supply pressure must be corrected.
Common Failure Symptoms and Diagnostic Procedures for the Ignitor/Orifice Assembly
The 316536602 frigidaire Oven Ignitor/Orifice Assembly is a combined glow ignitor and burner orifice subassembly that controls initial ignition and metered gas flow to the oven burner. In normal operation the ignitor rapidly heats to emit a visible orange glow and draws sufficient current to allow the gas valve to open; the orifice provides the defined orifice orifice or jet that ensures correct fuel pressure and flame geometry. Typical failure modes include a weak or non-glowing ignitor that does not reach operating temperature fast enough (resulting in long preheat times or no ignition), an intermittently glowing element, or a clogged orifice that produces a low or irregular flame. Confirming compatibility with the appliance control and valve train is necessary before replacement as electrical characteristics and orifice sizing determine safe operation and correct flame performance.
diagnostic procedures combine visual, electrical and gas-flow checks. Start with a visual inspection for cracked or blistered ignitor surfaces, corrosion at electrical connectorsand debris in the orifice; then perform an electrical continuity and resistance check at the ignitor leads and a live-state voltage/current measurement at the control harness while observing glow behavior (power off before disconnecting). If the ignitor glows but the valve does not open, test the gas valve coil and measure the control circuit voltage; if the ignitor never reaches full glow yet draws little current, the ignitor is highly likely fatigued and should be replaced. For orifice-related symptoms such as yellow flame or reduced heat, remove the orifice and inspect for deposits or deformation and verify that the orifice size matches specifications for the appliance model.
- Symptom: No glow or vrey slow glow – Test: measure ignitor continuity and operating current; result indicates open or weak element.
- Symptom: Glow but no ignition – Test: verify control voltage to gas valve and valve coil resistance; result indicates valve or wiring fault.
- Symptom: Low or yellow flame – Test: inspect and clean or replace orifice; result distinguishes flow restriction from ignition problem.
| Item | Description |
|---|---|
| Continuity | Ignitor should show continuity; open circuit indicates failed element. |
| Live observation | Ignitor must reach visible orange glow and remain steady while control applies voltage. |
| Orifice inspection | Orifice must be free of debris and sized per model; deformation or clogging alters flame. |
Compatibility, Replacement considerations, Installation Steps, and Post‑Install Troubleshooting
The 316536602 frigidaire Oven Ignitor/Orifice assembly is a matched ignition and metering component that establishes the initial flame for the oven burner. Functionally, the ignitor must provide sufficient heat and current draw to allow the gas valve to open while the orifice delivers the correct gas flow for the burner geometry; a mismatch in orifice diameter or in ignitor electrical characteristics changes flame shape, combustion timing, and safety system behavior. When selecting a replacement, cross‑reference the oven model/serial data and confirm mounting orientation, harness connector typeand manifold interface so the assembly seats correctly and the oven’s flame sensor or thermocouple remains positioned in the flame envelope.
Installers should follow isolation and verification procedures and use diagnostic checks to confirm correct operation after replacement. Verify ignitor continuity and visualize a strong, even glow before the valve actuates; after assembly, perform a leak test at the fittings and observe flame characteristics during a controlled light cycle. If the oven exhibits delayed ignition, intermittent flameor the ignitor glows continuously without valve opening, systematically check harness continuity, connector pins, supply voltage at the valveand control board outputs before changing additional components. Disconnect electrical power and shut off the gas supply prior to any work.
- Typical install checklist: disconnect power/gas; remove access panel; compare part and orientation; replace gasket and secure mounting; reconnect harness; perform leak test.
- Key post‑install checks: confirm ignitor glows, verify valve actuation, observe proper flame shape, check for error codes or lockouts from the control board.
- Troubleshooting cues: continuous glow without ignition suggests weak valve or control output; no glow indicates open ignitor or loss of supply; intermittent flame frequently enough points to loose connectors or a marginal ignitor output.

Q&A
What is the 316536602 Frigidaire Oven Ignitor/Orifice Assembly and what does it do?
The 316536602 is a replacement hot surface ignitor and orifice assembly used on certain Frigidaire electric/gas range bake systems. The ignitor glows hot to ignite the gas coming through the orifice (gas jet) so the burner lights reliably. The assembly combines the ignitor element and the gas orifice/mount so it can be replaced as a single unit.
Wich Frigidaire models is part 316536602 compatible with?
Compatibility varies by model and production date. This part is used on a range of many Frigidaire/Kenmore/White-Westinghouse gas oven models. Always verify fit by checking your oven’s model number against the manufacturer parts list or the parts seller’s compatibility chart before ordering. Do not rely solely on visual similarity.
What are common symptoms that indicate the ignitor/orifice assembly needs replacement?
Typical symptoms include the oven burner failing to light, a long delay between the ignitor glowing and the burner lighting, the oven ignitor glowing but gas valve not opening, oven not reaching set temperatureor the oven cycling on and off without producing flame. Physical damage, cracking of the ignitoror a broken connector are also clear indicators.
How can I test the ignitor without removing it from the oven?
First make sure the power and gas are off for safety. You can test electrical function using a clamp meter to measure the current draw while the ignitor is calling for heat (requires turning power back on briefly and observing safe distance). A properly operating hot surface ignitor typically draws measurable current when cold; a much lower current than expected often means the gas valve won’t open.For a simpler test, with power off you can check continuity with a multimeter-an open circuit indicates a failed ignitor. Refer to the manufacturer’s specifications for exact resistance/current values for your model.
Can I clean the orifice rather of replacing the whole assembly?
Light dirt or spider/web obstruction in the orifice can sometimes be cleared carefully, but cleaning is delicate and can damage the tiny jet opening.Because the part also contains the ignitor and mounting hardware, technicians usually replace the entire assembly to ensure proper ignition, correct orifice sizingand a safe, reliable seal. If converting between natural gas and LP, the orifice size must be changed to the correct specification-do not attempt conversions without proper parts and adjustment.
What safety steps should I follow when replacing the 316536602 assembly?
Turn off electrical power to the oven at the breaker and shut off the gas supply before beginning work. Allow components to cool. Work in a well-ventilated area and avoid open flames. Use the correct replacement part and tighten fittings to prevent leaks. After installation, check all gas connections with a leak-detection solution and restore power to verify operation. If you are not comfortable or qualified to work on gas appliances,hire a licensed technician.
What tools are typically needed to replace this ignitor/orifice assembly?
Common tools include a nut driver or socket set (usually 1/4″ to 3/8″ sizes), screwdrivers, pliers, a multimeter for electrical checksand a leak-detection solution for gas fittings. A flashlight and small mirror can help with visibility. If measuring current, a clamp ammeter is recommended. Have replacement gasket material or a new gasket if the old one is damaged.
Is the 316536602 an OEM part and are there aftermarket alternatives or warranty concerns?
