Lochinvar & A.O. Smith 100187881 Ignitor Assembly
The Lochinvar & A.O. Smith 100187881 Ignitor Assembly is a critical OEM replacement part engineered for high-efficiency commercial gas water heaters, specifically the BTH, SUF, and HCG series. As a veteran-grade spark ignitor assembly, this component ensures precise ignition timing in 300, 400, and 500 MBH models, as well as 200/201 series units. When troubleshooting water heater ignition failure, the 100187881 is the primary solution for restoring the electronic ignition sequence. Built to withstand high-combustion temperatures, this standard spark igniter replaces older standing pilot systems to improve fuel efficiency and safety. For commercial HVAC maintenance, technicians rely on this part to eliminate nuisance lockouts. Proper installation requires verifying the gap between the electrode and the burner to ensure a consistent blue spark. This 100187881 ignitor is cross-referenced with various legacy part numbers, making it a versatile boiler ignition part for diverse mechanical room applications.
Key Benefits:- Direct OEM Compatibility: Specifically designed for Lochinvar and A.O. Smith BTH/SUF/HCG high-efficiency commercial models.
- Rugged Electrode Performance: Features a durable ceramic insulator and high-grade spark electrode to prevent grounding issues in high-heat environments.
- Precision Ignition: Facilitates reliable electronic spark ignition, reducing fuel waste and preventing delayed ignition cycles.
- Simplified Field Replacement: Standard mount design allows for rapid installation during HVAC service calls to minimize system downtime.
- How do I confirm if my 100187881 ignitor is faulty? Check for a visible blue spark through the sight glass during the trial for ignition; if the controller shows an ignition lockout code but the gas valve is energized, the electrode or high-voltage lead may be compromised.
- Does this assembly include the gasket? While this is the 100187881 spark ignitor, always check the integrity of the existing burner gasket during removal to ensure a proper airtight seal upon reassembly.
- Which models specifically use this ignitor? This unit is widely used in A.O. Smith Cyclone and Lochinvar Shield commercial gas water heaters ranging from 200 to 500 Series.
