LG Appliance Repair in Greater Boston, MA

LG builds its own platforms and manufactures compressors and motors that end up inside other manufacturers' appliances as well, which is why an LG component sometimes turns up behind another badge. LG refrigeration drives the sealed system with a linear compressor whose piston is driven directly rather than through a crank, which makes it quieter and more efficient and means the diagnostic procedure for a conventional reciprocating compressor does not apply to it. LG's linear and inverter compressors are commanded by a dedicated inverter board, so a refrigeration fault is a three-part question — compressor, inverter, or the main board driving it — rather than a single component test. Most current LG appliances will also play a diagnostic tone sequence into the manufacturer's app, which is worth doing while you are still on the phone.

Because the compressor and its drive electronics fail as a pair often enough to matter, we test the inverter before condemning a sealed system on LG refrigeration. That order is the difference between a board and a compressor replacement. LG is among the platforms we see most, so the components that fail on it are already stocked. We ask for the model number when you book so the technician can load the likely parts before setting off, which is the single biggest factor in finishing on the first visit.
