If your LG refrigerator's lights, display and fans work but both sections slowly warm up, the linear compressor may be failing. First rule out cheaper causes like dirty coils, a failed fan or a defrost fault. Then check coverage: LG has offered extended parts coverage on linear compressors for many models, often up to 10 years, though labor and refrigerant may not be included.

Signs of a Failing Linear Compressor
- Both fridge and freezer gradually warm over a day or two.
- Lights, display and interior fans still work.
- Clicking or a repeated start-stop sound from the back bottom.
- The compressor runs but the back and sides don't get warm the way they used to.
- Ice cream softens, and the ice maker slows or stops.
Rule Out These First
| Cause | Clue | Typical cost |
|---|---|---|
| Dirty condenser / condenser fan (Er CF) | Hot back, fan not spinning | $130–$260 |
| Defrost failure (Er dH) | Frost on freezer back panel, fridge warm | $160–$300 |
| Evaporator fan (Er FF) | No airflow in freezer | $150–$280 |
| Inverter or main board | Often after storms; compressor gets no power | $200–$450 |
| Linear compressor / sealed system | Confirmed by testing | Parts may be covered; labor and refrigerant quoted |
Check Your Coverage Before Paying
- Find the model and serial number on the label inside the fresh-food section.
- Look up your warranty with LG, or call LG with the serial number.
- Ask what's covered: compressor part only, or also labor, refrigerant and sealed-system work.
- Keep your purchase receipt and any service records.
Repair or Replace?
If LG covers the compressor part, repair often costs a fraction of a new fridge, especially for InstaView or counter-depth models. If the unit is older and not covered, compare the full sealed-system quote against a comparable new fridge using the 50% rule.
Why Clearwater Heat Matters
Compressors run longer in a Florida summer, and dirty coils make it worse. Cleaning coils every 6 months and keeping airflow around the fridge reduces strain. Surge protection helps protect the inverter board that drives the compressor.

What Is a Linear Compressor?
A conventional compressor uses a crankshaft to turn rotation into piston motion. A linear compressor drives the piston directly in a straight line, which reduces friction and noise and improves efficiency. LG has used linear and inverter linear compressors across many refrigerator lines. They're controlled by an inverter board, so board failures can look like compressor failures, which is why testing matters.
Questions to Ask Your Technician
- Did you confirm the compressor failed, or is it the inverter board?
- Is there a refrigerant leak, and where?
- What does the quote include: compressor, drier, refrigerant, labor?
- Which parts could LG's coverage pay for?
- How long will parts take to arrive?
Keep Your Food Safe During a Long Repair
Compressor repairs sometimes need parts ordered. Keep a cooler and ice ready, move perishables first, and keep the freezer closed; a full freezer holds about 48 hours. If the repair will take days, a temporary fridge may be worth it.

Frequently Asked Questions
If the lights and fans work but the fridge and freezer slowly warm, and cheaper causes like dirty coils, fans and defrost parts have been ruled out, a technician can test the compressor and inverter board to confirm.
LG has offered extended parts coverage on linear compressors for many models, often up to 10 years. Labor and refrigerant may not be included, so check your model and serial number with LG.
Often yes if the part is covered and the fridge is otherwise in good shape. Without coverage on an older unit, compare the quote with a new fridge.
