Freezer not freezing (food soft, compressor running or not)

Rule out setting, load and door seal first, then airflow and condenser, then start components. On frost-free uprights, a choked evaporator from a defrost failure is a top cause. If the compressor runs steadily, the condenser is clean and the evaporator is not frosted but the cabinet still won't pull down, it is a sealed-system issue to refer out.

Before you start

  • Unplug before removing panels or touching relays, fans or wiring.
  • Live-voltage checks are caution work: insulated probes, one hand, no jewelry.
  • Never cut, braze or recharge the sealed system; many units use flammable R-600a.

Freezer frost build-up (gasket, manual defrost chest, frost-free failure)

Most chest and many small upright freezers are manual defrost, so some frost is normal and must be removed when it reaches about 1/4 inch. Fast or patchy frost near the door points to a leaking gasket or heavy door use. On frost-free uprights, frost on the coil behind the panel means the defrost system has failed.

Freezer runs all the time

Freezers normally run 40-80% of the time at room temperature and more in a warm room. Check load, setting, room temperature, door seal and condenser before suspecting a part.

Freezer not running (no compressor, or clicking)

Work from power to control to start components. A click-hum-click pattern every few minutes usually means the compressor is not starting: check the start relay/overload. If the relay is good and the compressor still won't start, compressor diagnosis and replacement is sealed-system work to refer out.
