LG Refrigerator Linear Compressor Problems: Signs & Solutions

LG refrigerators have been popular in Canadian homes for over a decade — but a significant number of LG models from 2014–2020 have a well-documented issue with their linear compressor. If your LG fridge has stopped cooling, is making unusual noises, or is showing specific error codes, the linear compressor may be to blame. Here’s what you need to know.

What Is a Linear Compressor?

LG introduced its linear inverter compressor as a more energy-efficient, quieter alternative to traditional rotary compressors. Rather than rotating, the linear compressor’s piston moves back and forth in a straight line. LG marketed this heavily — and while the technology works well when it works, a manufacturing defect in certain production runs led to premature failures.

Signs Your LG Linear Compressor Is Failing

• Fridge is warm but freezer is still cooling — one of the most common early signs
• Both fridge and freezer are warm — compressor may have stopped running entirely
• Clicking sound followed by silence — the compressor attempting to start and failing
• Error code Er FF, Er rF, Er Co, or Er 1F — fan and cooling-related faults that often accompany compressor failure
• Fridge runs constantly but doesn’t cool properly — compressor running but not building pressure

How to Diagnose the Problem

A technician can perform a compressor test by measuring amperage draw and checking the start relay. However, there are a few things you can check first:

1. Check the condenser coils: Dirty coils at the back or bottom of the fridge can cause a working compressor to overheat and shut down temporarily. Clean them and see if cooling resumes.
2. Listen for the compressor: Stand near the back of the fridge and listen. A functioning compressor hums steadily. A clicking-then-silence pattern suggests start failure. Complete silence suggests the compressor isn’t running at all.
3. Check for error codes: Press and hold the Freezer and Refrigerator temperature buttons simultaneously for 3 seconds to enter diagnostic mode on most LG models.

Is There a Warranty or Class Action Coverage?

LG extended its compressor warranty to 10 years on many affected models following consumer pressure and class action lawsuits in the United States. In Canada, the situation is similar but the coverage terms vary. Key points:

• LG Canada extended compressor warranties on affected models to 10 years from original purchase date
• Labour coverage is separate and typically limited to 1–2 years — meaning even under warranty, you may pay for the labour of a compressor replacement
• Proof of purchase is required for warranty claims

Check LG Canada’s website or contact LG directly with your model and serial number to confirm your warranty status before booking a repair.

Repair vs Replace: LG Compressor Decision

If your LG fridge is out of warranty, a compressor replacement typically costs $400–$700 including parts and labour. Whether this is worthwhile depends on the age of the fridge:

• Under 7 years old: Repair almost always makes sense — the rest of the appliance has significant life remaining
• 7–12 years old: A judgment call — consider what a comparable replacement would cost
• Over 12 years old: Replacement may be more economical, especially if other components are also aging

FAQ

Which LG models have the linear compressor problem?

The issue primarily affects LG French door, side-by-side, and bottom-freezer refrigerators manufactured between 2014 and 2020 with linear inverter compressors. Check your model number at LG Canada’s support page.

Can I claim a LG compressor repair through my home warranty?

Many home warranty plans cover appliance compressors. Review your home warranty policy and contact your provider before proceeding with a paid repair.

How long does a compressor replacement take?

Typically 2–3 hours on-site. The fridge should be emptied beforehand and will need several hours to return to temperature after the repair is completed.
