Quick answer
A Toshiba refrigerator that is not cooling is usually caused by a frosted evaporator (defrost failure), a failed fan motor, dirty condenser coils, or a compressor/inverter problem.
Why your Toshiba fridge is not cooling
When a Toshiba refrigerator stops cooling but the lights still work, the power supply is fine — the problem is in the cooling system. The most common cause is a frosted evaporator coil blocking airflow, followed by a failed evaporator fan, dirty condenser coils, and compressor or inverter issues.
Systematic troubleshooting
- Check temperature settings. Ensure the thermostat dial or digital control is not accidentally set to the warmest position or turned off. On models with a digital panel, look for "Cooling Off" or "Demo Mode" — press and hold the correct button combination (often Power Freeze + Fridge Temp for 3 seconds) to exit demo mode.
- Listen for the compressor. Put your ear near the bottom-rear of the fridge. A low hum means the compressor is running. Complete silence or repeated clicking means the compressor is not starting.
- Check the evaporator fan. Open the freezer door — you should feel cold air being blown. If not, the evaporator fan has stopped. This can be caused by ice blocking the blades or a dead fan motor.
- Check for ice buildup. Remove the freezer rear panel. If the evaporator coil is encased in ice, the defrost system has failed. Manually defrost (unplug for 8-12 hours with doors open, towels below) and then investigate the defrost heater, thermostat, and timer.
- Clean the condenser coils. Dusty coils at the bottom or back of the fridge prevent heat dissipation. The compressor overheats and shuts down. Vacuum or brush them clean.
- Check door seals. Close the door on a piece of paper — if you can pull it out easily, the gasket is weak and warm air is entering the fridge, causing it to struggle.
- If none of the above helps, the compressor or inverter board may have failed. Call a qualified technician.
Food safety: If the fridge temperature exceeds 8 degrees C, move perishable food to a cooler or neighbour's fridge within 2 hours to prevent spoilage.
What does the Not Cooling code mean?
A Toshiba refrigerator that is not cooling has a fault in the cooling system — evaporator frost, fan failure, dirty condenser, or compressor/inverter problem — while the power supply is working.
Common causes
- Frosted evaporator coil blocking airflow (defrost failure) — most common
- Evaporator fan motor stopped (ice or motor failure)
- Dirty condenser coils causing compressor overheat and shutdown
- Compressor or inverter board failure
- Thermostat set too warm or demo mode active
- Weak door gasket allowing warm air infiltration
- Start relay or overload protector failure
- Low refrigerant from a slow leak

How to fix the Not Cooling error
Check temperature settings
Ensure not set to warmest or demo mode. Exit demo mode if active.
Listen for the compressor
Hum = running. Silence or clicking = not starting.
Check evaporator fan
Open freezer — should feel cold air blowing. No airflow = fan problem.
Check for ice on evaporator
Remove freezer rear panel. Ice-encased coil = defrost system failure.
Manually defrost if iced
Unplug 8-12 hours, doors open, towels below.
Clean condenser coils
Vacuum or brush dust from bottom/rear coils.
Check door seals
Dollar-bill test. Replace gasket if loose.
Call a technician
If compressor is not starting or inverter board is suspected.
Safety first: Move perishable food to a cooler if the fridge temperature exceeds 8 degrees C for more than 2 hours. Unplug before accessing internal components.
Part you may need: Evaporator fan / defrost heater / condenser coils / compressor
Toshiba inverter compressors often carry a 5-10 year warranty. Check your warranty card before paying for compressor replacement.
Frequently asked questions
Freezer works but fridge is warm — why?
The evaporator fan or the air duct between freezer and fridge is blocked. Cold air is not reaching the fridge section.
Can I manually defrost to fix it?
Yes — if the evaporator is frosted over, a manual defrost restores cooling immediately. But find and fix the defrost system fault or it will refreeze.
How often should I clean condenser coils?
At least twice a year. Monthly if you have pets or live in a dusty area.
