ADH73150208 Genuine Filter Drier Assembly for LG Fridges, Refrigeration Sealed System Drier

ADH73150208 is a genuine LG drier assembly, a sealed system part for LG fridges. The drier, also called a filter drier, sits in the refrigerant line and traps moisture and debris before they can reach the narrow capillary tube. It's not a DIY part. A filter drier is normally replaced whenever a fridge's sealed system is opened, so this listing is mainly for refrigeration technicians matching LG's part number.

What the drier does in an LG fridge

Inside the sealed system, refrigerant carries heat from the cabinet to the condenser and back again. Any moisture in that loop can freeze at the capillary tube, and any grit or metal particles can block it. The drier contains a desiccant and strainer to catch both. A failing or saturated drier can lead to a fridge that cools for a while then warms up, frost forming at the drier or capillary outlet, or a compressor running non-stop with poor cooling. Because a drier starts soaking up moisture as soon as it's exposed to air, a new one is fitted after any compressor, leak or blockage repair.

Licensed refrigeration work

In Australia, opening a fridge's sealed system and handling refrigerant requires a licensed refrigeration technician. The fridge is unplugged, the refrigerant is recovered, and the old drier is cut out and the new one brazed in, kept sealed until the last moment. The system is then pressure tested, evacuated, recharged and checked for correct operation.

Questions about this part

Can I replace the drier myself?

No. Working on the sealed system means recovering and handling refrigerant, which requires a licence in Australia. Order the part for your refrigeration technician, or ask them to confirm ADH73150208 suits your fridge model first.
