Problem summary
Your Nordmende freestanding freezer is running but not maintaining cold temperatures. Food may be thawing or the cabinet feels warm to the touch. This is often caused by one of three main issues: a faulty cooling fan, a failed temperature sensor, or a worn motor. The good news is that some of these parts are replaceable by a confident customer.
Likely causes
Based on 42 similar reports from our engineers, the most common causes are:
Cooling fan (33% of cases) The evaporator fan circulates cold air through the cabinet. If it's seized, clogged with ice, or has failed electrically, air won't reach the compartment even though the compressor is working.
Temperature sensor (24% of cases) This component tells the freezer's control board when to switch the compressor on and off. A faulty sensor may stop the cooling cycle entirely, leaving the motor idle.
Compressor or motor (19% of cases) The compressor pumps refrigerant; the motor drives the fan. If either has failed, cooling won't work. These require a qualified engineer.
What you can try yourself
Before calling for a repair, check the following:
1. Check the thermostat dial Locate the cooling compartment thermostat knob (usually inside the cabinet). Ensure it is set to position 2–3 for normal use, not to 1 (minimum cooling). If it's been accidentally turned to the lowest setting or off, adjust it and allow 4–6 hours for the freezer to re-cool.
2. Inspect the door seal Open the door and run your fingers around the rubber gasket. Look for cracks, gaps, or poor sealing. A torn or misaligned seal lets warm air in constantly, forcing the compressor to run without ever reaching the target temperature. If the seal is visibly damaged, it will need replacement.
3. Check for ice blockage around the fan If you can safely access the evaporator fan compartment (consult your manual for the exact location), look for accumulated frost or ice. A heavily iced fan won't spin. Do not attempt to chip ice away with sharp tools; thaw it gently with a cloth or allow it to melt naturally after switching off the freezer for an hour.
4. Listen for the compressor and fan Switch the freezer on. Within a few seconds, you should hear the compressor hum and feel slight vibration. If there is no sound or vibration at all, the compressor or motor may have failed.
Why this needs an engineer
If the thermostat is set correctly, the seal is intact, and you can hear the compressor running but the freezer still won't cool, the fault is likely inside the sealed refrigeration system or the motor itself. These components—the compressor, motor, and sealed pipes—involve high-pressure refrigerant and electrical components. Attempting a repair carries serious safety and environmental risks.
If you're in Northern Ireland, SMC Services can usually book a repair within 2–3 working days.
When to call SMC Services
- The freezer runs but doesn't cool after you've checked the thermostat and seal.
- You hear the compressor but the cabinet remains warm.
- The door seal is visibly cracked or doesn't close properly.
- You suspect a failed fan motor or temperature sensor and aren't confident replacing parts yourself.
