Lochinvar & A.O. Smith 100210087 Valve

Lochinvar & A.O. Smith 100210087 Valve

As a veteran tech, you know that a failing Natural Gas Control Valve is a top cause for ignition failure and erratic burner cycles. The Lochinvar & A.O. Smith 100210087 Valve is a genuine OEM replacement part engineered for specific high-efficiency residential and commercial water heaters, including many State and American Water Heater models. This direct-acting gas valve regulates the manifold pressure and gas flow to the burner based on signals from the control board, ensuring consistent combustion and preventing dangerous over-firing or flame loss.

The 100210087 features a compact valve body designed for tight cabinets, making it a reliable HVAC repair part for contractors handling 250 and 400 series units. Proper gas valve troubleshooting often points to this component when natural gas water heaters fail to maintain set-point temperatures. When installing, always verify your inlet and manifold pressures with a calibrated manometer to ensure this A.O. Smith gas control is dialed into factory specs for peak efficiency and safety.

Key Benefits for the Job Site:
  • OEM Precision: Eliminates the compatibility headaches common with universal or aftermarket gas control valves.
  • Optimized Flow Control: Maintains steady natural gas delivery for reliable ignition and stable flame signals.
  • Direct Fitment: Designed for an exact match on Lochinvar and A.O. Smith commercial and residential models.
  • System Security: Prevents gas leakage and protects the heat exchanger from excessive thermal stress.
Common Questions & Contractor Insights:

Is the 100210087 compatible with Propane (LP) systems?
No, this specific part number is calibrated for Natural Gas only. Attempting to use this on an LP system without a verified conversion kit is a safety hazard.

What are the signs this valve needs a swap?
Technicians typically look for a "No Flame Detected" lockout, erratic clicking from the solenoid, or if the gas valve fails to open during the ignition sequence despite receiving 24V from the control.

Do I need to calibrate this out of the box?
While OEM gas valves are factory set, a pro should always perform a combustion analysis and check the manifold pressure during high-fire to ensure the unit is running within the manufacturer’s specified range.
