Refrigerator Not Cooling? Possible reasons:

❄️ 1. Dirty or Blocked Condenser Coils
(Most common reason a refrigerator stops cooling)
The coils underneath or behind your fridge remove heat from the refrigerant. When they get dirty or clogged with dust, hair, and kitchen debris, the fridge must work harder — and eventually stops cooling.
Signs Your Coils Are Dirty:
Fridge running constantly
Warm temperature inside
Hot air blowing from the bottom/back
Excessive dust build-up
DIY Fix:
Unplug the refrigerator
Remove toe-kick panel or pull unit away from wall
Use a coil brush or vacuum to clean them
Plug back in and wait a few hours
⚠️ If the fridge still doesn’t cool after cleaning the coils, there may be a sealed system issue (refrigerant leak, compressor failure), which requires EPA-certified repair.

❄️ 2. Faulty Evaporator Fan (Freezer Fan)
The evaporator fan circulates cold air from the freezer into the fridge. If it stops working, your freezer may stay cold, but the refrigerator becomes warm.
Symptoms:
Freezer is cold, fridge is warm
Fan is loud, clicking, or not spinning
You don’t feel air circulation inside fridge
DIY Check:
Open freezer door and listen
If the fan is silent while compressor is running → It likely failed
👉 This is not a DIY repair. Replacing the fan requires removing paneling and defrost system components.
❄️ 3. Defrost System Failure (One of the top Samsung/LG issues)
If the defrost system stops working, frost builds up and blocks airflow.
Signs of Defrost Failure:
Ice buildup on the back freezer wall
Loud buzzing or scraping noise
Water leaking under fridge
Fridge warm, freezer cold
The defrost system includes:
Defrost heater
Defrost thermostat
Defrost sensor
Control board
Any of these can fail.
Why it happens often in Samsung refrigerators:
Samsung models are notorious for defrost drainage issues and evaporator icing — one of the most common refrigerator repair calls in Florida.
👉 Requires professional service to avoid further damage.
❄️ 4. Low Refrigerant / Sealed System Leak
This is one of the most serious issues.
If your fridge has a refrigerant leak, compressor failure, or capillary tube restriction, the refrigerator can’t maintain temperature.
Symptoms:
Fridge slowly gets warmer over days
Compressor runs constantly
No frost pattern on evaporator
Clicking noises
Only an EPA-certified technician can diagnose sealed system issues, check pressures, and repair leaks.

❄️ 5. Compressor Failure
(Often LG or Samsung)
The compressor is the heart of the refrigerator.
Signs of compressor failure:
Clicking every 30–60 seconds
Humming but no cooling
Overheating at the back of fridge
No vibration when plugged in
Newer LG and Samsung models use inverter compressors that require specialized testing.
⚠️ Do NOT attempt DIY repairs on compressors.
❄️ 6. Blocked Air Vents or Overpacked Fridge
Sometimes cooling issues are simple and inexpensive:
If food is pushed against the air vents, airflow is blocked, temperature rises, and food spoils.
DIY Fix:
Make space around vents (back wall)
Lower fridge load
Set temperature to 37°F + freezer 0°F
Wait a few hours
❄️ 7. Temperature Control Board / Thermostat Failure
Modern refrigerators depend on digital temperature sensors and control boards.
Symptoms of sensor/board issues:
Fridge temperature randomly fluctuates
Fridge won’t defrost
Freezer works but fridge does not
No error codes but poor cooling
Brands impacted:
✔ GE
✔ Whirlpool
✔ Samsung
✔ LG
✔ Frigidaire
Boards require diagnostic tools and are not DIY-fixable.
🔧 When You Should Call a
Professional Technician Immediately

✔ Refrigerator is completely warm
✔ You hear clicking or buzzing
✔ Freezer is cold but fridge is warm

These are urgent signs of:
Sealed system leaks
Failed compressor
Blown defrost heater
Evaporator fan failure
Control board issues
