The Goodman B1226207 Suction Line Accumulator is the genuine OEM refrigerant accumulator for the APH1560M41AB packaged heat pump. Installed on the compressor suction line, the accumulator traps liquid refrigerant during defrost cycles and low-load operation, metering it back to the compressor as vapor. This is critical on a heat pump, where reversing-valve defrost cycles routinely send liquid toward the compressor — without a working accumulator, liquid slugging can score valves and destroy the compressor.
The B1226207 is sized to the APH1560M41AB's refrigerant charge and line diameters, with the correct internal volume and metering orifice. A mismatched universal accumulator can be over- or under-sized, hurting oil return and capacity. The OEM part guarantees the right hold-up volume and inlet/outlet geometry for a clean braze.
Professional (4/5). This is a sealed-system repair. Recover the refrigerant, cut/unbraze the old accumulator, braze in the replacement under nitrogen, pull a vacuum, and recharge to nameplate. EPA 608 certification and brazing tools are required — not a DIY part.
