316536602 Frigidaire oven Ignitor/Orifice Assembly is a combined ignition and gas metering component used in Frigidaire gas ovens and ranges; it integrates a hot surface ignitor element with a matched orifice that directs and meters burner gas for reliable ignition. As a replaceable service part, the assembly combines the electrical ignition element (often a hot surface or glow-type ignitor) with the mechanical gas orifice that shapes flow to the bake or broil burner, allowing a single part to serve both ignition and primary gas delivery functions in the burner module.
Inside the appliance the ignitor/orifice assembly interfaces directly with the gas valve, oven control module, and the oven’s safety circuits. The ignitor provides the heat source to ignite gas at the burner while the orifice defines the gas flow and pressure characteristics for the intended burner output; the control module and gas valve sequence power to the ignitor and gas flow based on user commands and temperature feedback from the oven sensor. Proper operation therefore depends on correct electrical continuity and current draw from the ignitor, correct orifice sizing for the burner and gas type, and intact wiring and mounting that maintain alignment and combustion stability.
This article explains the assembly’s function and construction, outlines model compatibility and how the 316536602 part is typically used, and describes common failure symptoms and diagnostic checks a technician or informed owner can perform.You will find guidance on troubleshooting (visual inspection, electrical measurements, and combustion observations), verification of compatibility with specific Frigidaire models, and practical replacement considerations such as correct orientation, sealing and torque of fittings, safety precautions (power and gas isolation), and when to involve a qualified service technician.

functional Role and Performance Specifications of the Oven Ignitor/Orifice Assembly
The 316536602 Frigidaire Oven Ignitor/Orifice assembly is a combined ignition and gas metering component that provides the initial thermal energy to ignite the oven burner while controlling the gas jet geometry for stable combustion. The ignitor element converts electrical power into heat (glow) to open the safety gas valve in sequence with the oven’s control circuitry,and the orifice defines the volumetric flow rate for the specific fuel type and burner port. In practice, technicians assess the ignitor by observing glow behavior and measuring electrical continuity and current draw, and thay verify the orifice by confirming size and gas-type compatibility; a mis-sized orifice or a weak ignitor can cause delayed ignition, incomplete combustion, or a failure-to-heat condition.
Installation and service require attention to electrical connector type, mounting orientation, and gas type; the assembly must match the oven’s valve pressure and burner head geometry to maintain correct air-fuel ratio and flame stability. Troubleshooting commonly involves measuring ignitor resistance,checking for steady full glow under applied voltage,and confirming that the orifice corresponds to LP vs natural gas service where applicable. Below are practical indicators and service points technicians use during diagnosis:
- Symptoms: slow ignition, continuous clicking, or no flame despite glow present.
- Electrical checks: continuity and steady glow current; intermittent open circuit indicates replacement.
- Gas compatibility: verify orifice size and labeling for the oven’s fuel type before replacement.
- Fitment: confirm mounting bracket and connector match to avoid leaks or misalignment of the flame impingement.

How the 316536602 Frigidaire Oven Ignitor/Orifice Assembly operates Within the oven gas Delivery and Ignition Circuit
The 316536602 Frigidaire Oven ignitor/Orifice assembly combines a hot-surface ignitor with a matched gas orifice to complete the oven’s ignition interface between the control electronics and the gas valve. When the oven control calls for heat, the ignitor is energized and heats to a red‑hot temperature; the control monitors the ignitor’s electrical behavior (current draw or voltage drop characteristics) and only energizes the gas valve coil when the ignitor indicates it has reached its operating state. The orifice is sized and positioned relative to the ignitor so that, when the valve opens, the flow rate and jet geometry produce a stable, ignitable gas‑air mixture for the burner ports used by the specific Frigidaire model the assembly fits.
In normal operation the assembly produces a repeatable sequence that ensures safe ignition: the ignitor must reach sufficient thermal and electrical characteristics before the gas valve will open, and the glowing element then ignites the gas issued through the orifice. Technicians will observe several practical behaviors tied to the assembly’s condition: a weak or failing ignitor may glow dimly or take much longer to reach temperature and will prevent valve actuation, a clogged or mis‑sized orifice will change flame shape or heat output, and wiring or harness faults can mimic component failure. Useful checks include visual confirmation of full glow, verifying continuity and connector integrity, and confirming the replacement part’s physical alignment and orifice specification to the oven’s service literature prior to installation.
- Control calls for heat → ignitor energized and heats

| Orifice | Precision jet that meters gas flow for correct burner pressure and flame characteristics |
| Gas valve / control interface | Control circuitry and valve coil that only open gas flow when ignitor electrical characteristics meet the safety threshold |
Common Failure Symptoms and Diagnostic Indicators: Ignition Delay, Weak Flame, Electrical Resistance and Current Draw
The 316536602 Frigidaire Oven Ignitor/Orifice Assembly combines a hot-surface ignitor element and a matched orifice to heat and meter gas for reliable ignition. The ignitor must reach a specific temperature and draw sufficient current so the gas valve sees the required hold current; if it does not, ignition will be delayed or the valve will not open. The orifice controls gas flow and flame shape, so a partially obstructed or mismatched orifice can produce a weak or yellow flame even when the ignitor glows normally. This assembly is intended as a direct-replacement component for Frigidaire ovens that use a hot-surface ignition system, and understanding both the electrical behavior of the ignitor and the physical condition of the orifice is essential for compatibility and proper combustion behavior.
- Ignition delay: prolonged glow without flame, or ignition taking more than a few seconds.
- Weak or yellow flame: reduced gas flow or improper mixing from the orifice.
- High electrical resistance or low current draw: indicates a degraded ignitor element.
- Intermittent flame or repeated reignition attempts: can be caused by marginal current preventing full valve opening.
Technically, diagnose by measuring cold resistance with a multimeter and measuring current during a call for heat with a clamp meter; acceptable ranges vary by model but typical cold resistance is on the order of a few tens of ohms and operating current commonly falls in the low amperes. A measured resistance significantly above the expected range or an operating current below the valve’s specified hold current points to a failing ignitor, while visual inspection of the orifice for carbon buildup or deformation explains many weak-flame complaints. For practical troubleshooting, verify supply voltage, confirm the control is providing voltage to the ignitor during start, record the time from energizing the ignitor to flame establishment, and replace the 316536602 Frigidaire Oven Ignitor/Orifice Assembly if electrical or flow characteristics fall outside the expected ranges.
| Item | Description |
|---|---|
| Typical cold resistance | ~30-80 Ω (model-dependent; higher values indicate element degradation) |
| Typical operating current | ~2.5-4.0 A during warm-up; currents below valve hold specification cause ignition failure |
| Ignition delay threshold | Ignition taking longer than 3-5 seconds from full glow suggests reduced ignitor performance |
Compatibility, Replacement considerations, and Step‑by‑Step installation Procedures for frigidaire Models
The 316536602 Frigidaire Oven Ignitor/Orifice Assembly combines the hot-surface ignitor element and the gas metering orifice into a single replaceable unit used on a subset of Frigidaire gas ovens. Functionally, the ignitor heats to a temperature that allows the oven gas valve to modulate and the matched orifice meters the correct gas flow for a stable burner flame. Compatibility is determined by mechanical mounting pattern,harness/connector type,and the orifice size for the intended fuel (natural gas or LP). Cross-referencing the appliance model and the part number is necessary because two assemblies with similar-looking elements can differ in bracket geometry, lead length, or connector style, any of wich can prevent correct installation or reliable operation.
- Isolate power and gas before begining work.
- Remove the oven access panel or floor and disconnect the ignitor harness.
- Unfasten the mounting screws and remove the old ignitor assembly, handling the ceramic element by the metal flange only.
- Install the new assembly, secure the mounting, reconnect the harness, and restore power and gas.
- Verify cold-resistance per the service manual, run an ignition cycle, inspect flame shape and stability, and perform a gas-leak test at fittings.
| Item | Description |
|---|---|
| Connector | Match the harness plug style and pin configuration to the oven harness-connector mismatch is a common incompatibility. |
| Mounting | Bracket orientation and screw pattern must align with the oven’s burner box or bracket; some models use angled mounts. |
| Orifice / Fuel | Orifice diameter is fuel-specific; change to the correct orifice when converting between natural gas and LP. |
| Functional check | Measure cold resistance and perform ignition/flame tests per the technical manual to confirm correct operation. |
During installation,avoid touching the ignitor’s ceramic surface as oils and mechanical stress reduce life expectancy. After installation, a technician should observe several ignition cycles to confirm consistent ignition timing and flame distribution; intermittent ignitions frequently enough indicate a cracked element, weak ignition current, or incorrect orifice sizing.If ignition fails or the valve cycles unusually, re-confirm wiring continuity, secure ground connections, and verify that the orifice orientation and fuel pressure match the oven’s specification before further diagnosis or replacement of adjacent components such as the gas valve or flame sensor.
Q&A
What is the 316536602 Frigidaire Oven Ignitor/Orifice assembly and what does it do?
The 316536602 is an OEM replacement assembly that contains the oven’s hot surface ignitor and the gas orifice/holder. The ignitor heats (glows) to ignite burner gas for the bake/oven burner, while the orifice meters the gas flow from the valve to the burner. together they ensure reliable ignition and correct flame size.
How do I know if this part is compatible with my oven?
Verify compatibility by matching the part number (316536602) to your appliance model. Locate your range/oven model number (usually on the oven frame behind the door or on the broiler compartment) and check the manufacturer parts list or Frigidaire’s online parts lookup. Many parts lists will also show cross-references; if in doubt, order by your appliance model or buy from an authorized Frigidaire parts supplier.
What are the common symptoms of a failing ignitor/orifice assembly?
common signs include: the oven burner failing to light, long ignition times (several attempts before the burner lights), the ignitor glowing but not opening the gas valve, clicking or repeated ignition attempts, uneven baking due to weak flame, or smelling gas (if ignition fails altogether). If you smell gas,stop using the appliance and ventilate the area-do not attempt ignition tests with an open flame.
how can I test the ignitor to see if it needs replacement?
Two practical tests: 1) Continuity: with power off and the ignitor disconnected, use a multimeter to check for continuity; lack of continuity indicates a broken filament. 2) Current draw test: with the oven calling for heat, measure the ignitor current with a clamp meter-most hot-surface oven ignitors typically draw around 2.8-3.6 amps when healthy. Continuity alone does not guarantee sufficient current draw, so a low current reading usually means replacement is needed. If you are not experienced with live-current measurements, hire a technician.
Can I replace the 316536602 assembly myself, and what safety precautions should I take?
Technically a competent DIYer can replace this assembly, but working with gas and live wiring has safety risks. Always disconnect electrical power and shut off the gas supply before starting. Avoid touching the new ignitor’s ceramic/glass element with bare hands (oil can shorten life). After installation, restore gas and perform a leak test (soapy water or approved leak detector) on fittings-do not use an open flame. If you are not agreeable with these steps, hire a qualified service technician.
Do I need to replace the orifice when replacing the ignitor?
Not always. The orifice is often included in the assembly because it’s part of the burner feed and can be damaged, clogged, or mismatched. If the existing orifice is the correct size and in good condition, you could reuse it, but using the complete OEM assembly guarantees correct fit, orifice size and proper sealing. It’s common and often recommended to replace both together to avoid further troubleshooting.
How long does this part typically last and are OEM and aftermarket versions different?
Typical life varies with usage and operating conditions, but many oven ignitors last 5-10 years. OEM (Frigidaire) parts are made to original specifications and usually offer better fit and reliability; aftermarket parts can be cheaper but vary in quality-inspect connectors, mounting, and orifice size carefully. Check the seller’s warranty-OEM parts often come with limited warranties.
How much does the 316536602 assembly cost and where should I buy it?
Prices vary by supplier and region; expect OEM ignitor/orifice assemblies to cost more than standalone aftermarket ignitors. Buy from frigidaire-authorized dealers, major appliance parts retailers, or reputable online parts stores and verify the part number and return policy. if uncertain, provide your appliance model number to the seller to confirm a correct match before purchase.
