Freezer runs but does not get cold enough; temperature hovers just below or above freezing.

Safety: Unplug the freezer before cleaning coils or accessing the rear compartment.

Steps:

• Clean condenser coils: Use a coil brush and vacuum to remove dust and lint from the condenser coils located at the back or underneath the unit.
• Check condenser fan: On frost-free uprights, verify the condenser fan runs whenever the compressor is on. If it is slow, noisy, or not running, replace the condenser fan motor.
• Inspect door gasket: Look for frost patterns near the door area inside the cabinet, indicating warm air leaks. Replace a damaged or hardened gasket.
• Check loading and airflow: Avoid overpacking the freezer and keep vents clear. Ensure the unit has proper clearance from walls for ventilation.
• Professional sealed system check: If the compressor runs continuously, coils are clean, fans and gaskets are good, but the unit still cannot reach set temperature, a sealed system issue (low refrigerant, restriction, or weak compressor) is likely and requires a certified technician.
