Compressor Failure: What It Means and How to Deal With It

A compressor is the heart of any fridge or washing‑machine that uses a cooling cycle. When it stops working, the whole appliance can feel useless. Knowing the symptoms and simple checks can save you time and money.

Signs Your Compressor Is Going Bad

First thing to notice is a loss of cooling. If your fridge runs warm or your washer takes forever to spin, the compressor might be the culprit. You may also hear a loud humming or clicking that gets louder before the machine shuts off.

Other clues include frequent on/off cycling, a burnt smell from the back of the unit, or visible overheating on the compressor housing. When the motor gets hot to the touch, it’s a red flag that something is wrong inside.

DIY Checks Before Calling a Technician

Before you pick up the phone, do a quick power check. Make sure the plug is secure and the circuit breaker hasn’t tripped. Resetting the breaker can sometimes revive a frozen starter.

Next, clean the condenser coils. Dust and grime make the compressor work harder and can cause it to overheat. Use a brush or vacuum to clear the fins, then wipe away any debris.

Listen for the start‑up click. If the compressor doesn’t make any sound at all, the issue may be electrical – a bad relay or a blown fuse. You can locate the relay on the control board and tap it gently; a click that follows often means the relay is stuck.

Finally, check for refrigerant leaks. Look for oil spots around the piping or a hissing sound. A leak reduces pressure, making the compressor stall. If you spot a leak, it’s time to call a pro.

Common Causes of Compressor Failure

Overheating is the top cause. It can happen when coils are dirty, the ambient room is too hot, or the fan that cools the compressor fails. Electrical problems like a bad start‑capacitor or a fried motor winding also crop up often.

Long‑term wear and tear is another factor. Compressors are built to last, but constant start‑stop cycles wear out the pistons and valves. Low refrigerant levels, usually from a leak, force the compressor to run harder, shortening its life.

When to Call a Professional

If you’ve cleared the coils, checked the power, and the appliance still won’t cool, it’s time to call an expert. Trying to open the sealed system or replace refrigerant yourself is dangerous and illegal in most places.

A qualified technician can test the compressor’s pressure, replace faulty relays, or install a new compressor if needed. Getting a professional assessment also helps you avoid emptying your warranty by doing the wrong DIY repair.

Preventive Care to Keep Compressors Healthy

Regular maintenance makes a huge difference. Clean the condenser coils at least twice a year and keep the area around the appliance clear for proper airflow.

Check that the door seals on a fridge are tight – a leaky seal makes the compressor work overtime. For washing machines, avoid over‑loading; heavy loads strain the motor and the compressor.

Schedule a yearly service with a local repair company. A quick inspection can spot worn bearings, low refrigerant, or electrical wear before they cause a full breakdown.

By watching for the warning signs, doing simple checks, and keeping up with maintenance, you can extend the life of your compressor and avoid costly replacements.
