Refrigerator Not Cold

Quick answer

If your refrigerator isn't cold, first check the temperature settings and ensure the door seals properly. Clean the condenser coils and verify the evaporator fan is working. If these steps don’t resolve the issue, the compressor or thermostat may need professional attention.

Confirm the symptom

• Fridge compartment is warm to the touch
• Food is spoiling faster than usual
• No cold air coming from vents
• Refrigerator is running constantly
• Freezer is cold but fridge is not

Tools and prep

• Screwdrivers (flathead and Phillips)
• Flashlight
• Thermometer
• Vacuum with brush attachment
• Lint-free cloth
• Work gloves
• Turn off power to the refrigerator at the circuit breaker for safety

Step-by-step troubleshooting

1. Check Temperature Settings
   Do: Verify the temperature settings on both the fridge and freezer compartments.
   Observe: Settings are correct (typically 37°F for fridge, 0°F for freezer).
   Means: Incorrect settings may prevent proper cooling.
   Next: If settings are incorrect, adjust them and wait 24 hours to see if cooling improves.
2. Inspect Door Seals
   Do: Close the door on a piece of paper and try to pull it out.
   Observe: Paper slides out easily or feels loose.
   Means: Worn or damaged door seals allow cold air to escape.
   Next: Replace the door gasket if the seal is compromised.
3. Clean 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: Dirty coils reduce efficiency and cooling performance.
   Next: Use a vacuum to clean the coils thoroughly.
4. Check Evaporator Fan
   Do: Listen for the evaporator fan running when the fridge is operating.
   Observe: Fan is silent or makes unusual noises.
   Means: A malfunctioning fan can prevent cold air circulation.
   Next: Inspect the fan for obstructions or damage; replace if necessary.
5. Test Thermostat
   Do: Use a thermometer to check the internal temperature of the fridge.
   Observe: Temperature is higher than 40°F.
   Means: A faulty thermostat may not be regulating the temperature correctly.
   Next: Replace the thermostat if it's not functioning properly.
6. Check Compressor
   Do: Listen for the compressor to start and run.
   Observe: Compressor is silent or makes loud, unusual noises.
   Means: A failed compressor is a serious issue requiring professional repair.
   Next: If the compressor is not working, contact a professional technician.

Common causes

Parts matching

Common parts needed for refrigerator cooling issues include:

• Door gasket for sealing the door
• Evaporator fan motor for air circulation
• Thermostat for temperature regulation
• Condenser fan motor for coil cooling
• Compressor for refrigerant pumping

Always purchase OEM parts or high-quality replacements to ensure compatibility and performance.

When to call a professional

• The refrigerator does not cool at all after checking all settings and components
• You hear loud or unusual noises from the compressor
• You suspect a refrigerant leak (smell, hissing sound, or frost buildup on coils)
• The compressor does not start at all
• You are unsure about diagnosing or replacing internal components
