LG and Samsung Fridge Not Cooling? Compressor and Inverter Clues for Princeton
LG and Samsung make some of the most common refrigerators in Princeton homes — and their compressors fail in distinctive ways that confuse general repairers. LG uses a linear compressor. Samsung uses an inverter compressor. Both can leave a fridge warming slowly over days, with no dramatic noise and no obvious failure. Here are the clues for each.
LG: The Linear Compressor
LG's linear compressor works differently from a conventional compressor: instead of a motor turning a crank, a piston moves back and forth in a straight line. When it fails, it often fails gradually — the fridge cools less and less over days or weeks, the compressor runs constantly, and the fridge section slowly warms while the freezer follows. Owners often notice the food going off before they notice the fridge is the problem, because there is no bang, no click, and no sudden failure. If your LG fridge is slowly warming and the compressor never seems to cycle off, the linear compressor is the first suspect — not the thermostat, and not the fans.
Samsung: The Inverter Compressor
Samsung's inverter compressor varies its speed instead of simply switching on and off. When it fails, the symptoms are quieter and stranger: the fridge may cool intermittently, cycle in odd patterns, or warm up and then recover. Some Samsung fridges show error codes or flashing displays; others show nothing at all. A Samsung fridge that is warm in the fridge section but cold in the freezer, with no clear pattern, is worth checking for an inverter fault — especially if the fridge is a few years old and has never had a problem before.
What To Check Before You Call
- Both sections. Is the freezer cold and the fridge warm, or are both warm? The pattern matters.
- How long. Did it fail suddenly, or has it been warming slowly over days? Slow warming points at the compressor.
- The sound. Is the compressor running constantly, clicking, or silent? Constant running with poor cooling is the linear-compressor signature.
- The display. Samsung fridges may show error codes — note them before you call.
Why Brand-Specific Diagnosis Matters
A linear compressor and an inverter compressor are not diagnosed the same way as a conventional compressor, and they are not interchangeable parts. A repairer who treats every fridge the same will test the wrong things and order the wrong parts. Our fridge compressor repair service covers both designs, and our refrigerator not cooling page covers the checks that apply to any brand.

Frequently Asked Questions
Why is my LG fridge slowly warming up?
LG linear compressors often fail gradually — the fridge cools less over days or weeks, the compressor runs constantly, and the food goes off before the failure is obvious.
What is an inverter compressor?
A compressor that varies its speed instead of switching on and off. Samsung uses them widely. When they fail, the fridge may cool intermittently or warm with no clear pattern.
Do Samsung fridges show error codes?
Some do — note any code or flashing display before you call, as it helps diagnosis. Others show nothing at all.
Is a compressor repair worth it on an LG or Samsung?
On a newer or higher-end model, usually yes. On a standard model over ten years old, replacement is often the better spend. We give a straight answer after diagnosis.
