Lochinvar & A.O. Smith 100208324 Switch
The Lochinvar & A.O. Smith 100208324 On/Off Switch is a critical OEM replacement part designed for precise burner power control in high-efficiency hydronic heating systems. As a veteran-grade HVAC rocker switch, it provides a reliable interface for manual system cycling and emergency shutdowns. This specific 100208324 switch is engineered to meet the exact electrical specifications required for Lochinvar boiler models and A.O. Smith water heaters, ensuring seamless gas valve control and circuit integrity. Its durable construction is built to withstand the thermal demands of a mechanical room, preventing premature failure common with inferior aftermarket alternatives. Field technicians utilize this component to maintain the operational efficiency of units like the EnergyRite and Armor series. By ensuring a crisp, positive engagement, this power toggle switch eliminates intermittent connectivity issues that often trigger nuisance fault codes. For contractors, installing this genuine Lochinvar part ensures exact fitment and maintains the factory-calibrated performance of the appliance's ignition control circuit.
- OEM Compatibility: Exact drop-in replacement for Lochinvar SKU 100208324, also replacing obsolete part MSC2233.
- Broad System Application: Verified for use in AWN, OKN, SLA, SNR, and SWA series boilers and water heaters.
- Heavy-Duty Design: Industrial-grade snap-in toggle switch housing designed for high-cycle reliability in commercial environments.
- Fault Prevention: Restores stable power to the gas valve switch circuit, preventing unintended system lockouts.
Common Questions
How do I confirm if the 100208324 switch is compatible with my boiler?
Verify your model number against the supported list, including AWN151PM, AWN286PM, and OKN211. This switch is the standard burner on/off control for most Lochinvar Armor and Knight XL residential and commercial units.
What are the signs that my current on/off switch needs replacement?
If the burner fails to initiate despite a call for heat, or if the switch feels "spongy" or fails to lock into the on position, the internal contacts have likely degraded. Replacing with a 100208324 ensures the control circuit receives consistent voltage.
Can I use a generic rocker switch instead of this A.O. Smith OEM part?
While generic switches may fit the cutout, they often lack the correct amperage rating or heat resistance required for HVAC power switches. Using the 100208324 maintains the technical integrity of the manufacturer's wiring schematic.
