While you wait for the technician
Keep the door closed, move high-risk product to another unit or an insulated container with ice, and note the temperature readings. Do not try to chip ice off the evaporator coil; damaged fins and tubes turn a defrost repair into a coil replacement.
Maintenance that prevents emergencies
Most walk-in failures we see trace back to dirty condenser coils, worn gaskets and defrost systems that stopped working months earlier. A quarterly check of the coils, fans, defrost cycle and door hardware is the most cost-effective service a food business can schedule.
