Description
Lochinvar & A.O. Smith 100210041 Pilot Thermopile Assembly
The Lochinvar & A.O. Smith 100210041 is an OEM replacement Pilot Thermopile Assembly engineered to deliver consistent millivolt power generation from a standing pilot flame. Designed as a direct factory replacement for compatible Lochinvar and A.O. Smith water heaters and boilers, this thermopile assembly ensures reliable pilot flame detection and sufficient voltage output to power millivolt gas valve controls — keeping your heating system operating safely and efficiently.
Product Overview
A thermopile assembly converts heat from the pilot flame into electrical energy (millivolts) used to power the gas valve and maintain burner operation. When the original thermopile degrades or fails, the result is nuisance shutdowns, pilot outages, or complete system lockout. Replacing it with the correct OEM part restores full system performance and eliminates guesswork.
