Refrigerator Not Cooling Properly
If your fridge isn’t staying cold, check the thermostat first. Someone may have accidentally adjusted it. Set it to the right temperature, usually between 35-40°F. Next, inspect the door seals. If there are gaps or cracks, cold air could be escaping. Try closing the door on a piece of paper—if you can pull it out easily, the seals may need replacing. Also, check for dirt and dust on the condenser coils, usually located at the back or bottom. Cleaning them with a brush or vacuum can help improve cooling efficiency.
Fridge Making Strange Noises
A humming or buzzing noise is normal, but loud or unusual sounds could mean a problem. If you hear knocking sounds, loose parts might be the cause. Check the fan and compressor for any obstructions. A rattling sound may mean the fridge isn’t level, so adjust the legs if needed. If the noise is coming from the compressor and it won’t stop, the motor could be overworking, and professional help may be necessary.
Excessive Frost or Ice Buildup
If you notice ice forming inside the fridge or freezer, check the door gasket. If it’s damaged, warm air might be entering, causing excess frost. Another common reason is a blocked drain. If water isn’t draining properly, it can freeze and create ice buildup. Locate the drain hole and clear any clogs using warm water.
Refrigerator Leaking Water
Water puddles under your fridge can be frustrating. A common cause is a clogged or frozen drain line. Try using a thin wire or warm water to clear it. Another reason could be high humidity. If the door is frequently opened, moisture can collect and drip down. Make sure the doors close fully.
Fridge Running Constantly
A refrigerator that never stops running could be struggling to keep up. Dirty condenser coils, poor ventilation, or an overfilled fridge can all cause this. Make sure there’s enough space around the fridge for air to circulate, and avoid cramming too much inside.
If you’ve tried these steps and your fridge still isn’t working right, it may be time to call a professional. Regular cleaning and maintenance can also help prevent future problems and keep your refrigerator running smoothly.
