# LG sealed system repair

### What to establish before anyone quotes you a compressor

Three questions, in this order. Has the air side actually been ruled out — fans, defrost, a coil packed with dust — because most cabinets sent for a compressor never needed one. Has anyone put gauges on the machine, or is the diagnosis a guess wearing a confident face. And what is the manufacture date on the sticker inside the door, because LG's linear compressors carry an unusually long parts coverage that follows the machine rather than the person who bought it. We look that up before a number is written down, and it has ended the conversation in the owner's favor more than once.

What this involves

Diagnosed with gauges, never from a symptom or a code

The compressor warranty position is established before any figure is given

Recovery, drier, vacuum and charge — the whole procedure or none of it

Prove it is the sealed system

Air and defrost ruled out first, with numbers. Most cabinets sent for a compressor did not need one.

Check the warranty

LG's compressor cover follows the machine. A cabinet bought used can still be covered, and it changes the number considerably.

Recover properly

Refrigerant is recovered, not vented. This is not negotiable and it is not optional.

Braze, replace the drier, pull a vacuum

A system opened to atmosphere in Miami has taken on moisture. Skipping the drier or the vacuum is how a repair fails in six months.

Weigh the charge in

By weight, to the plate. Not by gauge pressure and not by feel.

### Is it ever worth doing on an older machine?

This is the one repair on this site where the honest answer is sometimes no, and we will say so. A twelve-year-old cabinet with a tired gasket and a slow ice maker is a poor place to spend that money. A four-year-old French door with a covered compressor usually is not.

### How long does it take?

A day at the machine when the parts are on the truck, and it cannot be hurried. Recovery, brazing, a new drier, a proper vacuum and a weighed charge each take the time they take, and a cabinet rushed through that stage is a cabinet we would be back at.
