Is your fridge humming but not getting cold? Or maybe it’s making weird noises? Before you call a repair service, try a few quick checks. Most fridge issues have an easy fix that you can do in ten minutes. This guide walks you through the most common problems, what you can test yourself, and when you should pick up the phone.
First, look at the power source. Make sure the plug is seated firmly and the circuit breaker hasn’t tripped. A loose plug is the simplest reason a fridge stops working.
Next, examine the temperature settings. New owners sometimes set the dial too warm, thinking it saves energy. Set the freezer to about -18°C (0°F) and the fridge to 3‑5°C (37‑41°F). Give it a few hours to stabilize.
Check the door seals. Close the door on a piece of paper; if you can pull it out easily, the gasket is leaking air. Clean the seal with warm, soapy water and dry it well. A cracked seal needs replacement – most stores sell them for a few pounds.
Watch the condenser coils. Over time, dust builds up and the fridge works harder. Unplug the unit, pull it away from the wall, and vacuum or brush the coils at the back or underneath. This alone can improve cooling by up to 20%.
Listen for the compressor. You should hear a low hum and occasional clicks. If it’s silent or rattling, the compressor may be the problem. That’s a sign to call a professional.
If you’ve checked power, settings, seals, and coils, but the fridge still isn’t cold, it’s time for a pro. Issues like a faulty thermostat, a broken evaporator fan, or a refrigerant leak require specialist tools and certification.
Also, if you notice water pooling inside or at the bottom, it could be a blocked defrost drain. DIY fixes exist, but they involve removing panels and cleaning hidden tubes – a task that can damage the unit if done wrong.
Another red flag is a loud, continuous buzzing or knocking noise that doesn’t stop. That often points to a failing compressor or motor, and attempting a repair yourself can be dangerous.
Finally, keep an eye on the age of your fridge. If it’s over ten years old and needs multiple repairs, replacing it might be cheaper in the long run. Modern fridges are more energy‑efficient, so you could save on electricity bills.
In short, start with the easy checks, clean the coils, and make sure the doors seal properly. If those steps don’t bring the cold back, call a qualified repair service. They’ll diagnose the fault safely and get your kitchen back on track without you having to guess.
This guide walks you through how to diagnose a problem with your refrigerator, from weird noises to cooling issues, using easy step-by-step tips anyone can follow.
