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.

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.

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.
