Freezer runs constantly and rarely shuts off

Safety first: Unplug the freezer before cleaning or accessing fans.

• Check door seal: Look for frost around the door opening, which indicates air leaks. Clean and inspect the gasket; replace if damaged.
• Clean condenser: Vacuum and brush the condenser coils to improve heat rejection.
• Verify evaporator fan: Open the door, press the door switch, and listen for the fan. If silent, inspect and replace the evaporator fan motor as needed.
• Ambient temperature: Ensure the freezer is not in a very hot or unventilated space, which can cause long run times.
• Professional check: If all above are good and the unit still runs constantly without reaching set temperature, a sealed system issue may exist and requires a technician.
