Freezer problems, lifespan and upkeep

A freezer holds food at 0°F (−18°C) with a compressor, condenser coils and, on frost-free models, a fan and defrost system. Most trouble is the door seal, dust on the coils or frost. If food is going soft, start with freezer not freezing, or freezer frost buildup. If it's a fridge-freezer with a warm fridge side, see fridge warm but the freezer's still cold.

Common problems
How long it should last

Typical lifespan: about 12–20 years (around 16 on average)

Signs it is near the end:

  • The compressor runs almost constantly, or the freezer struggles to hold 0°F.
  • Repairs are frequent, or one costs more than half the price of a new freezer.
  • Frost keeps returning, or a door seal that no longer holds.
  • Your energy bill climbs for no other reason.
Basic upkeep
  • Vacuum the condenser coils (back or underneath) once or twice a year.
  • Check that the door gasket seals: a dollar bill should resist being pulled out when the door is closed on it.
  • Keep the freezer at 0°F (−18°C) or below, with a thermometer inside.
  • Defrost a manual-defrost freezer when the frost is about a quarter inch thick.
  • Keep it reasonably full, but leave space around the vents so air can circulate.
Common fixes

  • Furnace won't heat?

    FurnaceFall

    The furnace runs but the house stays cold, which is usually a clogged filter, a thermostat setting, or an ignition fault.

  • Heat pump not heating?

    Heat pumpFall

    The heat pump runs but the house stays cold, which is usually thermostat settings, a clogged filter, or an iced-over outdoor unit.

  • Washer won't drain?

    Washer

    Water is left in the drum after the cycle, which is usually a clogged pump filter or a kinked drain hose.

  • Fridge not cooling?

    Fridge

    The fridge section is warm or warming. The cause depends on whether the freezer is still cold, and the first fix is often free.

  • Washer won't spin?

    Washer

    The drum fills and washes but won't spin, which is usually an unbalanced load, the lid switch, or a drain problem.
