The Goodman B1225022S is a genuine OEM solenoid coil designed for the Goodman DSX160361AA 16 SEER, 3-ton outdoor air conditioner. The solenoid coil generates the magnetic field that actuates its companion valve — controlling refrigerant flow through metering or reversing functions. When a coil burns out or loses continuity, the valve can stick, causing poor cooling, refrigerant flow problems, or a unit that won't change modes. Replacing the coil is a fast, economical fix that avoids replacing the entire valve body.
This OEM coil is matched to the exact voltage, resistance, and bore size of your valve stem. Generic coils with the wrong voltage or fit can overheat, fail prematurely, or fail to fully seat on the valve. The genuine Goodman coil drops on without modification.
Easy to Moderate — The coil usually slides off the valve stem and is held by a single retaining nut or clip, with two low-voltage wire connections. With power off, most experienced DIYers complete the swap in 15–20 minutes; no refrigerant work is required to replace just the coil.
