Lochinvar & A.O. Smith 100187864 Blower Assembly
The Lochinvar & A.O. Smith 100187864 Blower Assembly is a critical OEM replacement component designed for high-efficiency gas water heaters and boilers. Engineered specifically for the Lochinvar BTH series (models 150, 199, 200, and 250) and equivalent A.O. Smith Cyclone systems, this assembly manages the precise air-to-fuel ratio required for sealed combustion. Operating on a standard 115/120V power supply, the unit features an integrated combustion blower motor and housing designed to meet strict UL safety standards. This assembly is the direct factory successor to part number 9008910005, ensuring a seamless drop-in fit without the need for field modifications. For technicians servicing Series 200 and 201 units, this genuine part is essential for maintaining the manifold pressure and venting integrity necessary for safe, long-term operation.
Key Benefits for the Contractor
- Universal Compatibility: Serves as the primary OEM replacement for select Lochinvar BTH and A.O. Smith BTH series gas water heaters.
- Optimized Combustion: Precision-balanced fan wheel ensures stable airflow and prevents "Ignition Failure" or "Blower Prover" fault codes.
- Direct Retrofit: Replaces obsolete part number 9008910005 with updated EBM-Papst RG148 motor technology for improved reliability.
- Safety Verified: UL-recognized construction maintains the system's original safety certifications and factory performance curves.
Common Technical Questions
Is this blower compatible with Series 100 units?
No, the 100187864 is specifically engineered for Series 200 and 201 BTH models. Always verify your unit's series number before installation to ensure the PWM signal and voltage requirements match.
What are the symptoms of a failing blower assembly?
Common indicators include excessive bearing noise, "Blower Prover" pressure switch errors, or the system failing to initiate the pre-purge cycle. If the motor hums but does not spin, the internal blower motor or capacitor may be compromised.
Does this include the mounting gasket?
While the assembly is standard, it is best practice to inspect the blower flange gasket during removal. If the gasket shows signs of wear or compression set, it should be replaced to prevent combustion gas leaks.
