It depends on whether your fridge is designed to self-defrost.
If it’s auto-defrosting: you should not need routine manual defrosts. Instead, defrost manually only if frosting starts to restrict airflow or temperatures begin drifting.
If it’s not auto-defrosting (or it’s in a very humid, high-traffic area): plan a manual defrost whenever frost reaches a few millimetres thick or you see airflow reducing at the back of the cabinet.
A practical approach is to use your HACCP temperature log as the trigger. If you see the unit running longer to recover or temperatures rising during service, schedule a defrost outside peak hours before it becomes a breakdown.
