Lochinvar & A.O. Smith 100165937 Ignitor
When you're troubleshooting a lockout on a Lochinvar Knight or Squire series, the Lochinvar & A.O. Smith 100165937 Ignitor is often the first component to inspect. This 120V silicon carbide hot surface ignitor is a critical OEM replacement part designed for precision-timed ignition cycles in high-efficiency gas-fired boilers and water heaters. It features a durable ceramic block base and an M-shape element optimized for rapid heat-up and reliable burner lighting. Engineered to replace obsolete or alternate part numbers like 100165904, PLT2400, and PLT3400, this ignitor kit ensures your system maintains its high-efficiency thermal rating without the energy waste of a standing pilot. In the field, look for common failure points such as hairline fractures or increased resistance across the element. To ensure the longest service life, always handle the assembly by the ceramic base to prevent skin oils from causing hot spots and premature failure on the high-temperature surface.
Key Benefits- OEM Compatibility: Direct fit for Lochinvar Knight, Squire, and A.O. Smith PB/PF 1500–2000 models.
- Rapid Ignition: High-performance silicon carbide construction provides fast, consistent 120V ignition trials.
- Complete Kit: Includes the necessary ignitor gasket to ensure a proper combustion chamber seal.
- Reliable Performance: Maintains strict flame signal integrity to prevent nuisance ignition failure lockouts.
What are the signs of a failing 100165937 ignitor?
Technicians typically find the inducer motor running while the hot surface ignitor fails to glow. You may also see an "Ignition Failure Lockout" error on the control board or notice localized white "hot spots" on the element indicative of impending failure.
Can this part be used in both residential and commercial units?
Yes, this 120V ignitor is cross-compatible across several Lochinvar and A.O. Smith commercial boilers and residential high-efficiency water heaters, provided the part number matches the manufacturer's technical manual.
Does this ignitor include a new gasket?
Yes, this OEM ignitor assembly comes with the required gasket to maintain a gas-tight seal at the mounting plate, which is essential for proper combustion analysis readings.
