Goodman B1225020 Wiring Harness

The B1225020 is the genuine OEM low-voltage wiring harness built for the Goodman ASH130301AD heat pump. This pre-terminated harness carries the control signals between the defrost board, reversing-valve solenoid, and sensor circuits. Cracked insulation, corroded terminals, or a chewed harness can cause intermittent operation, false defrost cycles, or no-heat calls — a fresh factory harness restores clean, reliable connections.

Specifications

Part number: B1225020
Component: Low-voltage control wiring harness
Brand: Goodman (also fits equivalent Amana builds)
Fits: ASH130301AD heat pump
Connectors: Factory-crimped, keyed plug-in ends
Rating: 24V control circuit

OEM vs. Generic

The OEM B1225020 arrives with the correct wire gauge, color coding, and keyed connectors so it plugs directly into the board and solenoid with no splicing. Generic wire kits force you to cut, crimp, and hope the pinout matches — a common source of miswiring. The OEM harness is the fast, foolproof choice.

Installation Difficulty: Easy

Unplug the old harness at each keyed connector and snap in the replacement — no cutting or crimping needed. Disconnect power first and photograph the routing before removal.
