Lochinvar & A.O. Smith 100208364 Ignitor

The Lochinvar & A.O. Smith 100208364 Ignitor is a critical OEM replacement part designed for high-performance combustion in Power-Fin boiler systems. This hot surface ignitor (HSI) is a 120V, 300W component engineered to provide reliable ignition for Lochinvar Power-Fin PB/PF250-1000 models and compatible A.O. Smith water heaters. As a veteran-grade technician’s choice, this part is identical to PLT2702 and PLT2702K, ensuring seamless HVAC part compatibility during field repairs. Constructed from durable silicon carbide, it withstands the intense thermal cycling required for commercial heating applications. When troubleshooting ignition failures, technicians should verify that the control board is outputting the correct voltage and inspect the ceramic insulator for hairline cracks. Replacing a fouled or high-resistance ignitor with a genuine 100208364 ensures consistent flame rectification and prevents nuisance lockouts, maintaining peak efficiency for commercial heating boilers and hot water supply systems.

• Direct OEM Replacement: Fully interchangeable with part numbers PLT2702, PLT2702K, and 100165910 for a perfect fit.
• High-Temperature Durability: Engineered for Lochinvar Power-Fin boilers, handling rapid heat-up cycles without degradation.
• System Reliability: Precision-matched 120V/300W electrical specifications facilitate stable gas furnace ignition and reduce maintenance downtime.
• Broad Compatibility: Supports a wide range of BTU ratings from 250,000 up to 1,000,000 BTU heating boilers.

Is the 100208364 compatible with my specific Power-Fin model?
This ignitor is the standard hot surface ignition component for Power-Fin PB and PF models ranging from 250 to 1000. Always verify the part number in your technical manual to ensure a match with the PLT2702K series.

What causes this ignitor to fail prematurely?
Common failure points include contamination from skin oils during handling, high supply voltage exceeding 132V, or excessive vibration within the burner assembly. We recommend handling the ceramic base rather than the element to prolong service life.

Can I use a 24V or 80V ignitor instead?
No. The 100208364 is a 120V component. Using an improperly rated ignitor will result in immediate part failure or a failure to reach the 1,100°F+ required for gas ignition.
