Easy DIY Refrigerator Troubleshooting Guide
There’s nothing worse than realizing your refrigerator isn’t cooling properly. This guide will walk you through five easy steps to troubleshoot and fix common refrigerator issues. Even if you need a repair professional, you’ll be better prepared to explain the issue, saving time and money.
Tools for the Job
Before you start diagnosing your refrigerator, gather these tools:
- Socket/ratchet set
- Wire stripper/cutter
Materials You May Need
- Evaporator fan and/or condenser fan (available on Amazon or at appliance stores)
Step 1: Check the Basics
Before diving into complex fixes, start with simple checks:
- Ensure the Refrigerator is Plugged In: It might sound obvious, but sometimes the fridge can get partially unplugged. Pets or accidental bumps can dislodge the cord. If the fridge light doesn’t come on when you open the door, check the plug.
- Verify the Thermostat Settings: Sometimes the temperature control gets bumped accidentally. Ensure it’s set to the correct cooling level.
- Inspect the Freezer Vents: Are large items like pizza boxes or ice cream blocking the vents at the back of the freezer? Cold air must circulate freely, so make sure the vents are clear.
Step 2: Clean the Coils
Dust and pet hair can accumulate on the coils under or behind your fridge, causing it to overheat and lose cooling efficiency.
- Unplug the Refrigerator: Always unplug before cleaning.
- Locate the Coils: Depending on your model, coils may be at the back or underneath.
- Vacuum the Coils Thoroughly: Use a vacuum with a brush attachment to remove dust and debris.
Step 3: Inspect and Clean the Condenser Fan
The condenser fan cools the compressor and coils. If it’s dirty or malfunctioning, it can affect cooling.
- Unplug and Pull Out the Fridge: Move it away from the wall.
- Access the Condenser Fan: Remove the back panel near the bottom.
- Clean the Fan Blades: Remove any debris with a soft brush.
- Check Fan Movement: Spin the fan blades manually to see if they move freely.
- Plug in the Fridge: With the back panel still off, plug in the fridge and wait for the compressor to start. The fan should start as well.
- Replace if Necessary: If the fan doesn’t run or makes unusual noises, it may need to be replaced (see Step 5).
Step 4: Replace the Evaporator Fan
If you can hear the compressor running but your fridge isn’t cooling, the evaporator fan might be the issue.
- Listen for Unusual Noises: A squealing or chirping noise when you open the freezer door is a common sign of a failing evaporator fan.
- Access the Evaporator Fan:
- Unplug the Refrigerator.
- Remove the Freezer’s Back Panel: Locate and remove any screws or plastic plugs.
- Expose the Fan: Remove any fan cover if present.
- Replace the Fan:
- Remove the Old Fan: Unscrew and disconnect the old fan.
- Install the New Fan: Attach the mounting bracket to the new fan motor, connect the wires, and secure it in place.
- Reassemble the Freezer: Replace covers and panels.
Step 5: Replace the Condenser Fan
If replacing the evaporator fan didn’t fix the problem, the condenser fan might be faulty.
- Access the Condenser Fan:
- Unplug the Refrigerator and Pull It Out.
- Remove the Back Panel Near the Bottom.
- Replace the Fan:
- Disconnect the Old Fan: Cut the wires close to the fan and remove it from its mounting bracket.
- Install the New Fan:
- Strip the Wires: Prepare the old wires to connect with the new fan’s wires.
- Connect the Wires: Use wire connectors to join the wires securely.
- Mount the New Fan: Attach it to the bracket and secure it in place.
- Reassemble the Back Panel: Replace any covers or panels.
- Test the New Fan:
- Plug in the Refrigerator.
- Ensure the Fan Runs When the Compressor Starts.
After following these five steps, your refrigerator should be back to keeping your food cool.
