Refrigerator Compressor Problems: What to Look For and How to Fix Them

If your fridge is warm, humming loudly, or not cooling at all, the compressor is often the culprit. The compressor is the heart of the fridge – it squeezes refrigerant and moves heat out of the cabinet. When it fails, the whole system stops working, and your food can spoil fast.

Quick Signs Your Compressor Is Bad

First, listen. A healthy compressor makes a low, steady buzz. If you hear rapid clicking, rattling, or it stops making any noise, that’s a red flag. Next, check the temperature. If the freezer is above 0°F (‑18°C) and the fridge is above 40°F (4°C), the cooling cycle is broken.

Another clue is a warm coil at the back of the fridge. The coils should feel slightly cool. If they’re hot, the compressor isn’t pushing the refrigerant through properly. Finally, look for frost buildup inside the freezer – a sign the defrost cycle isn’t completing because the compressor isn’t working.

DIY Checks Before Calling a Pro

Before you dial Weymouth Appliance Repair Services, you can run a few simple tests. Unplug the fridge for five minutes, then plug it back in. Sometimes the compressor’s overload protector trips and a reset restores function.

If the compressor still won’t start, locate the start capacitor (usually a small cylinder near the compressor). A visual inspection can reveal bulging or leakage. You can also test it with a multimeter if you’re comfortable handling electricity.

Another easy check is the temperature sensor. Use a fridge thermometer to verify the actual temperature versus the setting. If the sensor is far off, the compressor may be getting the wrong signal and shutting down.

When these steps don’t solve the problem, it’s time to call a professional. Compressors involve high pressure and refrigerant, which require certified handling. Trying to repair it yourself can be dangerous and may void any warranty.
