Quick answer

Check the temperature settings, ensure the door seals are tight, and clean the condenser coils. If the fridge still doesn't cool, the compressor or thermostat may need repair.

Confirm the symptom

Fridge compartment is warm to the touch
Food is thawing or spoiling faster than usual
Freezer is working but fridge is not cold
Fridge makes loud or unusual noises
Fridge is running constantly without cycling off

Tools and prep

Screwdriver (flathead or Phillips)
Thermometer (for checking fridge/freezer temps)
Vacuum with brush attachment
Lint-free cloths
Flashlight
Plug in fridge to a grounded outlet

Step-by-step troubleshooting

Check Temperature Settings
Do: Ensure the fridge is set between 37°F and 40°F and the freezer at 0°F.
Observe: Temperature is within recommended range.
Means: Settings are correct; move to next step.
Next: Check door seals
Check Door Seals
Do: Close the door on a dollar bill. Try to pull it out.
Observe: Bill slides out easily.
Means: Seals are damaged or loose.
Next: Replace door gasket
Inspect Condenser Coils
Do: Locate and clean the condenser coils (usually at the back or bottom of the fridge).
Observe: Coils are free of dust and debris.
Means: Coils were dirty, affecting cooling.
Next: Wait 24 hours and check temperature
Check for Obstructions
Do: Ensure the fridge is at least 2 inches away from walls and not blocking airflow.
Observe: Adequate space around the fridge.
Means: Obstruction was affecting airflow.
Next: Wait 24 hours and check temperature
Test Thermostat
Do: Place a thermometer in the fridge and check if it matches the thermostat reading.
Observe: Thermometer shows a higher temperature than the setting.
Means: Thermostat may be faulty.
Next: Replace thermostat
Listen for Compressor
Do: Listen for the compressor to kick in (normal hum is expected).
Observe: No sound or compressor runs continuously.
Means: Compressor may be faulty.
Next: Call a professional technician

Common causes

Cause	Likelihood	Difficulty	Part often needed
Faulty Thermostat The thermostat may not be sending the correct signals to the compressor.	Common	Easy–Medium	Thermostat
Dirty Condenser Coils Dust and debris reduce the efficiency of heat dissipation.	Common	Easy	None
Damaged Door Seal Air leaks through gaps in the door seal, causing the fridge to work harder.	Common	Easy	Door gasket
Compressor Failure The compressor may be malfunctioning and not circulating refrigerant.	Sometimes	Hard	Compressor
Refrigerant Leak Low refrigerant levels prevent proper cooling.	Rare	Hard	Refrigerant and repair kit
Evaporator Fan Failure The fan may not be circulating cold air properly.	Sometimes	Medium	Evaporator fan motor

Parts matching

Common parts needed for a refrigerator not keeping food cold:

Door gasket (for sealing leaks)
Thermostat (to regulate temperature)
Condenser coil cleaning brush (for maintenance)
Evaporator fan motor (for airflow issues)
Compressor (for major repair)

Always purchase OEM parts for compatibility and performance.

When to call a professional

Fridge still doesn't cool after checking all basic issues
Compressor is not running or makes loud noises
Refrigerant leak is suspected
You're unsure about diagnosing or replacing internal components
The fridge is under warranty and DIY repairs may void it

FAQ

How often should I clean the condenser coils?

Clean the condenser coils every 6–12 months to maintain efficiency.

Can a faulty thermostat cause the fridge to stop cooling?

Yes, a faulty thermostat can prevent the compressor from receiving signals to cool the fridge.

Why is my fridge running constantly but not cooling?

This could indicate a refrigerant leak, compressor failure, or a clogged defrost drain.

How do I know if the door seal needs replacement?

If a dollar bill slides out easily when placed in the seal, the gasket is likely damaged.

Is it worth repairing an old refrigerator?

If the fridge is over 10 years old, consider replacement unless the repair is minor and inexpensive.
