Walk-in Cooler Warm
A restaurant walk-in runs but will not hold temperature and product is warming. Read the box, then airflow, then the condenser — sealed system last.
Scenario briefing
The call
A restaurant reports their walk-in cooler is running but not holding temperature. Product on the shelves is beginning to warm and the kitchen manager is watching you.
The unit appears to be operating — you hear fan and compressor activity — but the box is not getting cold enough. There is no alarm and no error code on the control.
Work the sequence: confirm the real box temperature, then airflow at the evaporator, then heat rejection at the condenser. Sealed-system work is the last stop, not the first.
