Replacing a worn potentiometer with this genuine Schneider Electric kit eliminates "hunting" or erratic actuator behavior caused by dead spots in older resistive elements

Always verify your heater's model and serial number to ensure exact compatibility with this 23-inch shaft

this is a parallel circuit (voltage sensing) switch designed to control a single resistive heating element by cycling power to maintain the desired temperature

effectively signaling the modulation amplifier to transition to high fire when the ambient temperature falls below your target setpoint

it facilitates the safe conversion of 325-5A series line pressure regulators

Lochinvar & A.O. Smith 100189392 Valve R-407A Replacing a worn potentiometer withThe Lochinvar & A. O. Smith 100189392 Valve is a 24v Gas Valve Kit engineered for natural gas and liquid propane (LP) applications in high efficiency boilers and water heaters. Specifically designed for the Lochinvar FTX500 series, including FTX500L and FTX500N models, this valve kit provides precise fuel regulation to maintain consistent manifold pressure. As an essential component for direct spark ignition or hot surface ignition sequences, it
