The FV-4M1 relies on a vertical float mechanism to actuate the valve plug

Reliable Performance: Robust construction minimizes fatigue

This typically indicates the sensor rod is dirty or has developed high impedance due to oxidation

Bypassing a safety limit is strictly for temporary diagnostic testing by licensed professionals only

Technicians usually identify a failing wire by excessive noise during operation

York S1-025-38948-000 Reversing Valve Coil The FV-4M1 relies on aThe York S1 025 38948 000 is a precision engineered 24V Reversing Valve Coil designed for high duty cycle performance in residential and light commercial heat pump systems. Built to the exact specifications of York, Luxaire, and Coleman equipment, this solenoid coil facilitates the critical transition between heating and cooling modes by providing the electromagnetic force necessary to actuate the 4 way reversing valve. Operating on a standard 24V AC
