The B1226207 is a genuine OEM suction-line accumulator for the Goodman/Amana APH1549M41BA packaged heat pump. Positioned on the suction line ahead of the compressor, the accumulator traps liquid refrigerant and oil and meters it back to the compressor as vapor at a controlled rate. This is critical on heat pumps, where reversing-valve operation and defrost cycles can send liquid slugs toward the compressor — a leading cause of valve and bearing failure. A pitted, restricted, or leaking accumulator should be replaced to protect the compressor.
Accumulator sizing — internal volume, oil-return orifice, and connection dimensions — is matched to the system's refrigerant charge and compressor. An undersized or mis-orificed generic can starve the compressor of oil or allow slugging. The OEM B1226207 is dimensioned for the APH1549M41BA, ensuring correct oil return and compressor protection.
Advanced (5 of 5). Replacing an accumulator is a sealed-system repair: recover the refrigerant, unbraze or cut the old accumulator, braze in the replacement with nitrogen purge, pull a deep vacuum, and recharge to spec. This is EPA-certified-technician work — it is not a DIY part. Budget 2–3 hours plus recovery/recharge.
