Refrigerator not cooling: the safe checks

Before calling anyone, rule out airflow and door problems. These are the checks a technician does first, and they are all safe.

Before you start

Never open the sealed cooling system, cut into pipes, or add refrigerant. That work is illegal in many places without certification and dangerous everywhere.

  1. 1

    Confirm what is warm

    Note whether only the fridge side is warm or both sides. Only the fridge warm points to airflow; both warm points to the cooling system.

  2. 2

    Check the dial or app setting

    Make sure nobody knocked the temperature control or left a holiday/demo mode on.

  3. 3

    Clear the vents

    Move food away from the vents inside, especially the back wall and the gap between freezer and fridge.

  4. 4

    Look for frost

    Open the freezer and look at the back wall. Heavy frost or a solid sheet of ice means the defrost system needs a professional.

  5. 5

    Listen for the fan

    With the door closed, listen for a fan. Silence inside while the compressor hums often means a failed evaporator fan.

  6. 6

    Clean the coils

    Unplug it, then vacuum the dusty coils at the back or behind the kick plate. Blocked coils cause poor cooling.

  7. 7

    Check the door seal

    Close the door on a sheet of paper. If it slides out easily, the seal is leaking warm air in.

When to stop and get help

If the freezer is frosted solid, both sides are warm, or you hear clicking with no hum, stop here and book a technician.
