Refrigerator Troubleshooting 101: 8 Easy DIY Fixes

Your refrigerator works hard.

How hard? It accounts for about 10% of your total electrical bill — and that’s when things are going well.

When conditions are less than optimal, 10% can jump to 20% or even higher. Your fridge may run constantly or struggle to maintain temperature.

Less than optimal conditions might include:

• Dirty condenser coils and fan
• Blocked internal vents
• A grubby door gasket
• A clogged drain tube

…all of which can be fixed DIY.

1. Dirty Condenser Coils & Fan

Condenser coils dissipate the heat generated by the compressor. They can’t do their job effectively when they’re covered in dust and grime.

If your fridge runs more often or has trouble maintaining its temperature, it’s time to clean the condenser coils.

1. Unplug the fridge.
2. Locate the coils — usually either on the back of the unit or underneath.
3. Use a vacuum with a brush attachment or a coil cleaning brush to remove dust and debris.
4. Plug the fridge back in and monitor its performance to ensure the issue is resolved.

2. Dirty Door Gasket

The door gasket keeps cold air inside your refrigerator. A dirty or cracked allows cold air to escape, forcing your fridge to work harder.

1. Inspect the gasket for dirt or damage.
2. Clean the gasket with warm, soapy water and a sponge or cloth to remove buildup. Avoid harsh chemicals that could damage the rubber.
3. If the gasket is cracked or torn, replace it. Most gaskets are easy to install and can be purchased from home supply stores or online.

3. Blocked Internal Vents

Blocked vents can prevent cold air from circulating evenly, leading to inconsistent temperatures.

1. Check vents inside the fridge and freezer to ensure they’re free from obstructions. Items pushed too close to the vents can block airflow.
2. Rearrange items to create enough space for air to circulate freely.
3. Avoid overpacking your refrigerator — proper airflow needs room to move.

4. Dirty Drip Tray

The drip tray, located underneath your refrigerator, collects condensation. Left uncleaned, it can cause odors or reduce efficiency.

1. Remove the drip tray — typically at the bottom of the fridge near the condenser coils.
2. Empty and clean it with warm, soapy water. If there’s buildup, use a gentle scrub brush to remove it.
3. Rinse, dry, and place the tray back in its position.

5. Clogged Drain Tube

A clogged drain tube leads to water backing up and pooling inside your refrigerator. Fortunately, clearing a clogged drain tube is a straightforward fix.

1. Locate the drain tube. It’s usually at the back of the fridge, inside the freezer compartment, or near the base.
2. Use warm, soapy water and a turkey baster or straw to flush out the tube.
3. Use a pipe cleaner or a soft brush to dislodge stubborn debris.
4. Once the tube is clear, reassemble and check for improved drainage.

6. Misaligned or Unlevel Refrigerator

An unlevel fridge can cause cooling problems, leaks, and noises. A correctly leveled fridge improves efficiency and extends the appliance’s life.

1. Use a leveling tool to check if your refrigerator sits evenly, front to back, and side to side.
2. Adjust the leveling feet by twisting them clockwise or counterclockwise to raise or lower each corner of the fridge.
3. Ensure the doors close correctly when adjustments are complete.

7. Frost Buildup in the Freezer

Excess frost in the freezer can reduce efficiency and take up valuable space. Often, this is caused by a door left ajar or faulty seals.

1. Check the door seal for cracks or gaps and replace it if necessary.
2. Defrost the freezer by unplugging the fridge and leaving the door open until the frost melts. Place towels to collect water as it thaws.
3. Once defrosted, dry the interior thoroughly and set the refrigerator to the correct temperature (usually 0°F for the freezer).

8. Incorrect Temperature Settings

Sometimes, irregular cooling or freezing is simply due to the wrong temperature settings. Adjusting the thermostat takes only seconds.

1. Use an appliance thermometer to verify the current temperatures in the fridge and freezer compartments.
2. Ideally, the refrigerator should be around 37°F and the freezer at 0°F.
3. adjust the thermostat and monitor the performance over the next 24 hours if temperatures seem off.

Maintaining Your Fridge

Regular maintenance is essential to keep your refrigerator running at its best.

• Clean condenser coils and fan every six months.
• Keep internal vents clear by avoiding overpacking and rearranging items as needed.
• Check and clean the door gasket every few months.
• Keep the drip tray clean and clear of debris.
• Use a straw or turkey baster to flush the drain tube every three to six months.

FAQs: Refrigerator Troubleshooting

Q: Why is my fridge making strange noises?

Some noises are normal, like the compressor’s hum or a clicking sound when the defrost timer kicks in. However, loud or persistent sounds could indicate a problem with the motor or fan.

Q: What should I do if my refrigerator isn’t cooling at all?

First, check that it’s plugged in and receiving power. If so, try resetting the thermostat or checking for any blocked vents. If those steps don’t solve the issue, call a professional for repairs.

Q: Can I fix a leaky refrigerator myself?

It depends on the source of the leak. If it’s a clogged defrost drain or damaged door seal, the homeowner can usually fix it. However, if the leak comes from somewhere else, call a professional for repairs.

Q: How often should I clean my refrigerator?

We recommend cleaning your fridge every three months, with additional deep cleaning of coils and vents twice yearly. However, if you notice any odors or spills, address them immediately.

Q: How can I prevent odors in my refrigerator?

Store food in airtight containers and regularly check for expired or spoiled items. Clean the interior with baking soda and warm water every few months, and place an open box of baking soda inside to absorb smells.

Q: What causes ice buildup in my freezer?

Ice buildup is often caused by a faulty door gasket, a slightly open freezer door, or high humidity. Check the gasket for damage, ensure the door seals properly, and limit the amount of time the freezer door is open. Defrost the freezer if ice has already accumulated.

Q: Why is my refrigerator running constantly?

A refrigerator running constantly may indicate dirty condenser coils, a faulty temperature sensor, or a problem with the door seal. Begin by cleaning the coils and checking the seal. If the problem persists, call for professional help.
