316240600 Frigidaire Ignitor Mounting Screw is a specific fastener used to secure the ignitor assembly within compatible Frigidaire gas appliances. It is indeed a small, heat-resistant screw designed to fix the ignitor or ignitor bracket to the burner box or chassis, maintaining the precise position and mechanical stability required for reliable ignition. As a purpose-built component it is indeed selected for length, thread form and material properties suitable for high-temperature, vibration-prone environments common in ovens and ranges.
Inside the appliance the mounting screw’s primary role is mechanical: to hold the ignitor in the correct orientation and spacing relative to the burner and gas orifice so the ignitor can reliably heat or spark to initiate combustion. Because the ignitor must maintain a consistent gap and alignment, the fastener interacts indirectly with the ignition system, burner assembly, gas valve timing, and the surrounding thermal shielding; improper fastening can lead to misalignment, stress on the ignitor element or ceramic, intermittent electrical contact, or increased heat transfer to nearby components.The screw must therefore resist corrosion, tolerate repeated thermal cycling and be tightened to an appropriate torque so as not to crack brittle ignitor materials or loosen under vibration.
In this article you will find a focused technical discussion covering the function of the 316240600 mounting screw, its compatibility with Frigidaire models, common failure symptoms related to mounting hardware (such as ignition delays, intermittent operation, or visible movement of the ignitor), and how to inspect and troubleshoot mounting-related issues.The article will also outline replacement considerations-selecting the correct part number, matching thread size/length and material properties, and practical guidance on avoiding over-torque and mechanical damage-so technicians, engineers and appliance owners can make informed decisions when diagnosing or replacing ignitor mounting hardware.

functional Role and Mechanical Requirements of the Ignitor Mounting Screw
The 316240600 Frigidaire Ignitor Mounting Screw functions as the primary mechanical fastener that secures the hot surface ignitor assembly to the burner or mounting bracket. By maintaining axial and radial alignment, this screw ensures the ignitor element sits at the designed gap and orientation relative to the burner ports; any axial shift or loosening can change ignition timing or cause the ceramic insulator to fracture. In service, the screw must resist high local temperatures and repeated thermal cycling while avoiding galvanic corrosion with adjacent parts, as material degradation or thread loss directly affects ignitor stability and electrical grounding paths used by some ignition circuits.
Mechanical requirements for the screw include appropriate thread engagement and length, sufficient shear and tensile strength to hold the ignitor under vibration, and a head style that permits controlled seating without crushing the ignitor body. Practical considerations for technicians include ensuring matched thread pitch to the mounting boss, using a torque-limiting driver to achieve a snug seat without over-stressing the ceramic, and inspecting for stripped threads or corrosion before reinstallation. Common service checks and best-practice features include:
- Matched thread profile and full thread engagement to prevent pull-out or loosening.
- Corrosion-resistant material and heat-tolerant surface finish for long-term stability.
- Controlled torque submission to avoid cracking the ignitor or deforming the mounting flange.
- Use of plain washers or lock-style hardware only when compatible with electrical insulation requirements.

How the 316240600 Frigidaire Ignitor Mounting Screw Secures and Aligns the Ignitor Assembly Inside the Appliance
The 316240600 Frigidaire Ignitor Mounting Screw serves as the mechanical and alignment interface between the ignitor assembly and the appliance burner box or mounting bracket. Its primary function is to hold the ignitor body rigidly in the correct axial and angular position so the ceramic ignitor element and electrical connections are not subjected to bending or vibration. Proper seating of this screw ensures the ignitor tip maintains the designed offset and gap relative to the gas orifice and flame sensor; even small misalignments change the heat transfer to the thermocouple or the visible flame pattern, which can produce ignition delays or unreliable operation. The screw’s thread form, length, and head style must match the original design to achieve correct fit and to avoid introducing stress points in the brittle ignitor housing or stripping the sheet-metal threads used in many Frigidaire ranges and ovens.
During service or replacement, technicians should start the screw by hand to confirm correct thread engagement and then tighten it just enough to clamp the ignitor flange flat against the bracket without compressing any insulating bushings or deforming the ignitor base. Over-torquing is the most common installation error and can crack the ceramic or distort the alignment; conversely, an under-tightened screw allows movement that leads to intermittent ignition or noisy operation. Practical signs of a faulty mounting screw or incorrect alignment include persistent ignition delay, a visibly tilted ignitor, or fractured ceramic near the screw hole. If threads are damaged, use the OEM part or a compatible fastener of equivalent material and profile to restore the original mounting geometry rather than improvising with longer or coarser screws.
- Features: correct thread engagement and head profile maintain alignment and prevent mechanical stress.
- Behavior: secures the ignitor to resist vibration while preserving the designed gap to the gas orifice.
- Compatibility: matched to Frigidaire ignitor brackets and sheet-metal or captive nut fittings; verify thread and length before substitution.

Diagnostic Symptoms and Performance Effects of Ignitor Mounting Screw Failure
The 316240600 Frigidaire Ignitor Mounting Screw secures the ignitor assembly to the manifold and maintains the precise position and thermal coupling required for reliable ignition.Its mechanical role is to prevent axial or rotational movement under thermal cycling; loss of clamp force or damaged threads lets the ignitor shift away from the gas orifice or the support bracket, which changes heat transfer and can create electrical stress on the fragile ceramic ignitor. Compatibility matters: this screw is specified for certain Frigidaire ranges with particular thread size, length and heat-resistant finish – substituting a wrong length, thread pitch, or non-heat-rated fastener can lead to contact with live components, cracked ignitors, or stripped mounting bosses.
- Ignitor glows but burner does not light (extended glow time)
- Intermittent ignition or flame dropouts during a cycle
- Visible looseness, backing out of the screw, or stripped threads at the manifold
- Erratic oven temperature control or repeated retry cycles from the control board
- Cracking or chipping of the ceramic ignitor at the clamp point
| Item | Description |
|---|---|
| Typical effect on ignitor current | misalignment reduces thermal transfer, lowering amp draw below the gas valve threshold (commonly ~2-4 A depending on model), which prevents valve opening. |
| Common failure modes | Thread wear, heat-induced loosening, and screw shear causing movement or direct contact with the ignitor element. |
| Recommended inspection | Visual tightness check, inspect for stripped threads and ceramic damage, and verify proper part fitment before replacement. |
From a diagnostics viewpoint, verify mounting integrity before replacing the ignitor itself: an otherwise functional ignitor that meets resistance/current specifications can still fail to light the gas if the mounting screw allows misalignment or poor thermal conduction.Technicians should measure ignitor current under glow conditions and compare to the appliance-specific threshold; if current is low but the ignitor resistance is within spec, check the mounting screw and bracket alignment. replacing the fastener with the correct OEM 316240600 screw or an exact equivalent restores designed geometry and reduces the risk of repeat failures caused by improper clamp pressure or heat-degraded materials.
Replacement Considerations,Torque Specifications,and Step‑by‑Step Installation for the Ignitor Mounting Screw
The 316240600 Frigidaire Ignitor Mounting Screw secures the ignitor assembly to the burner or bracket and helps maintain mechanical alignment and electrical continuity under repeated thermal cycling. This screw is selected for its material resistance to heat and corrosion so it does not gall or deform the fragile ignitor element; technicians should confirm the part number against the appliance model and inspect the screw and mating threads for wear or stripping before replacement. Proper seating and contact are required to prevent vibration-induced movement or intermittent electrical connection that can affect ignition performance.
Installation requires controlled clamping force and correct sequence to avoid cracking the ignitor or damaging the bracket. Typical practice is to hand-start the screw, tighten progressively and evenly, and use a calibrated torque driver where available; a conservative range for small ignitor mounting screws is approximately 6-12 in‑lb (0.7-1.4 N·m), but verify the appliance service manual for the exact value.Follow these practical steps during replacement:
- disconnect power and gas; allow components to cool.
- Access the ignitor assembly, remove the old screw(s) and inspect threads and the ignitor mounting boss.
- Fit the new 316240600 screw, hand-start to ensure correct thread engagement, then torque to the specified value in small increments.
- Restore connections, perform an ignition test, and inspect for movement or arcing during operation.
