Lochinvar & A.O. Smith 100208379 Pressure Switch
The Lochinvar & A.O. Smith 100208379 Pressure Switch is a critical safety component designed for precise combustion air monitoring in high-efficiency water heaters and boilers. Calibrated to a .95" WC (Water Column) set point, this normally open switch ensures the inducer motor is generating sufficient draft before allowing the ignition sequence to proceed. As a genuine OEM replacement, it maintains the specific pressure differential required to prevent incomplete combustion and flue gas spillage. Technical specifications confirm compatibility with various sealed combustion systems across the Lochinvar and A.O. Smith product lines. Field technicians should verify the WC rating and terminal configuration to ensure a direct match for the existing draft inducer pressure switch. This HVAC replacement part is built to withstand high-cycling environments, providing reliable pressure sensing and circuit closure to keep the appliance operating within tight safety parameters.
Key Benefits- Precise Calibration: Factory-set at .95" WC to ensure accurate air pressure detection and system safety.
- OEM Reliability: Direct replacement part designed to meet original manufacturer specifications for fit and function.
- Rugged Construction: Engineered to handle the thermal demands and vibration of high-output boiler and water heater cabinets.
- Safety Compliance: Prevents the burner from firing if internal venting or intake pressures fall outside of safe operating ranges.
How do I troubleshoot a pressure switch error on a Lochinvar boiler?
Check for obstructions in the venting, verify the inducer motor is reaching full speed, and inspect the silicone tubing for cracks or moisture before testing the switch for continuity.
Can I use a switch with a different WC rating?
No. Using a switch with a different set point (.95" WC for this model) can lead to unsafe operation or frequent nuisance lockouts.
What causes a pressure switch to fail?
Common culprits include diaphragm wear, moisture buildup in the sensing lines, or carbon deposits affecting the electrical contacts.
