Introduction

Go to step 1

Use this guide to replace the compressor run capacitor in your LG refrigerator.

This guide will work for most LG refrigerators. This guide is written with an LG model LFX25973 refrigerator. If you have a different model, you may encounter some minor disassembly differences, but the overall repair process will be the same.

The compressor run capacitor is needed for the compressor to run properly. If it fails, your compressor may not run or will run poorly.

If you are experiencing poor cooling or the compressor isn't functioning, the run capacitor is one of the items to check. There may not be an error code associated with this condition.
