Lochinvar & A.O. Smith 100092683 Ignitor

The Lochinvar and A.O. Smith 100092683 Ignitor is a high-performance Norton hot surface igniter designed for precision combustion in residential and commercial gas-fired water heaters and boilers. This 120V HSI replacement is a critical component for maintaining consistent ignition cycles, specifically engineered to withstand the thermal stress of frequent cycling in high-efficiency systems. As a direct OEM replacement part, it ensures proper electrical resistance and rapid heat-up times, which are essential for preventing delayed ignition and the subsequent accumulation of unburned gas. This silicon carbide igniter is compatible with a wide range of models, including the JW402NVH FVIR water heater series. For technicians, installing this genuine 100092683 ignition part is the most reliable way to resolve common "no heat" calls and lockout errors, such as "flame fail ignition," by restoring the system to original factory specifications and ensuring long-term operational stability.

• Rapid Heat-Up Capacity: Reaches optimal ignition temperature in seconds to ensure immediate fuel combustion and high system efficiency.
• Precise OEM Specifications: Designed specifically for A.O. Smith and Lochinvar equipment, eliminating the mounting and fitment issues common with universal aftermarket igniters.
• Enhanced Safety: Consistent ignition performance reduces the risk of delayed ignition pulses and potential mechanical damage to burner assemblies.
• Broad Compatibility: Supports a variety of FVIR water heaters and gas-fired boilers, making it a versatile addition to any service truck's inventory.

• How do I test the 100092683 ignitor for failure? Use a multimeter to check for continuity or measure the ohmic resistance. An "open" circuit or a reading significantly outside the manufacturer’s specified range indicates a cracked or degraded element.
• What are the signs of a failing hot surface igniter? Common indicators include visible white cracks on the element, repeated ignition trial lockouts, or the unit glowing but failing to light the main burner.
• Does this part include the necessary mounting hardware? This hot surface igniter comes with the required lead wires and connector for a standard plug-and-play installation in compatible 120V systems.
