Possible Causes

Door gasket leaking cold air, Freezer installed in very warm environment, Thermostat or sensor slightly mis‑calibrated, Condenser partially blocked

How to Fix / Troubleshooting

Safety: Unplug before cleaning condenser or adjusting components.

Steps to reduce run time:

  • 1. Clean condenser: Remove dust from rear coils and ensure good airflow.
  • 2. Improve door seal: Check gasket with the paper test and replace if necessary.
  • 3. Adjust setpoint: If the freezer is colder than needed, raise the set temperature slightly (e.g. from −22°C to −18°C).
  • 4. Check ambient temperature: Avoid placing the freezer near ovens, radiators, or in unventilated cupboards.

Note: Some modern freezers run for long periods by design for efficiency, but they should still cycle off occasionally.
