Goodman B1225022S Solenoid Coil

The Goodman B1225022S is a genuine OEM solenoid coil for the GMT135-5 gas furnace. The coil energizes the solenoid valve, opening the gas path on a call for heat and closing it for safe shutoff. A weak, shorted, or open coil is a frequent cause of a valve that won't open, intermittent no-heat, or a furnace that ignites erratically. Swapping in a fresh OEM coil restores crisp, reliable valve actuation and safe gas control.

Specifications

Type: Replacement solenoid / gas valve coil
Function: Electromagnetically actuates the solenoid valve on heat demand
Fits: Goodman GMT135-5 and compatible furnace models
OEM Part Number: B1225022S
Brand: Goodman (genuine OEM)

OEM vs. Generic

Genuine Goodman coils match the specified coil resistance, voltage, and connector so the valve pulls in cleanly and holds without overheating. Generic coils can have mismatched resistance that causes weak actuation or premature failure. Because the coil directly controls the gas valve, OEM is the safe, dependable choice.

Install Difficulty

Easy (2/5). Disconnect power, remove the retaining clip or nut, slide off the old coil, fit the new one, and reconnect the leads. Typically a 15-minute repair. After installation, verify smooth valve operation and confirm there are no gas leaks around the valve body.
