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 alarm beeping

Identify which alarm (door, high temperature, power failure), silence it with the reset key, then fix the cause. Disabling alarms is not recommended because they protect food.

Freezer clicking, compressor not running

Same pattern as fridges: start relay or overload most often, then supply voltage, then compressor. Compressor work is sealed-system: refer.
