Lochinvar & A.O. Smith 100165932 Spark Ignitor
When you're dealing with a heater that will not fire, the Lochinvar & A.O. Smith 100165932 Spark Ignitor is a critical diagnostic starting point. This genuine OEM replacement part is engineered for high-voltage ignition sequences in Lochinvar EnergyRite Heaters, specifically models ER 152, ER 202, ER 252, ER 302, and ER 402. As a field-ready HVAC ignition component, it provides the precise 10,000 to 15,000-volt arc required to bridge the gap and light the burner consistently under varying gas pressures.
The 100165932 ignitor features a robust ceramic insulator and durable electrode tip designed to withstand the high-temperature environment of the combustion chamber. Replacing a fouled or cracked water heater spark ignitor restores reliable flame rectification and prevents common "Ignition Failure" lockout codes on the user interface. This kit is a direct-fit solution, ensuring the electrode is positioned for optimal spark-to-burner alignment, which is vital for preventing delayed ignition and rough starts in commercial and residential pool heaters.
Key Benefits:- OEM Compatibility: Specifically designed for EnergyRite heater models (ER152–ER402), ensuring seamless mounting and correct gap spacing.
- Enhanced Safety: Facilitates reliable burner startup, reducing the risk of unburned gas accumulation and system lockouts.
- Complete Integration: Often includes the necessary gasket and screws to ensure a gas-tight seal at the combustion interface.
- Technical Reliability: Engineered to handle high-voltage pulses from the integrated control board without insulation breakdown.
- How do I tell if the 100165932 needs replacement? If you hear the ignition sequence but see no blue arc through the sight glass, or if the ceramic base shows visible hairline cracks or soot buildup, the ignitor likely has an internal short.
- What causes these ignitors to fail? Excessive moisture in the combustion area, carbon fouling, or physical vibration can compromise the ceramic insulator or the electrode tip over time.
- Is a gasket required for installation? Yes, maintaining a proper seal at the ignitor mounting flange is essential for pilot stability and preventing flue gas leakage.
