- Thick ice on the evaporator coil, ceiling, or floor
- Ice building up around the door frame or on the threshold

- Compressor running continuously without pulling temperature down
- Soft product, freezer burn, or refrozen packaging
- Door will not latch or seal because of ice buildup
- Condensing unit short cycling or tripping breakers
How the Visit Works
Freezer diagnostics center on the defrost system, because most icing complaints trace back to it. I verify how defrost initiates — time clock, demand, or electronic controller — confirm the heaters actually draw current, and check the termination sensor and fan delay so the cycle ends correctly instead of running long or not at all. I test the drain line heater and clear the drain, since a frozen drain floods the box floor with ice. From there I take suction and discharge pressures, calculate superheat, evaluate the metering device, inspect the condensing unit and coils, test evaporator fan motors, and check door heaters, gaskets, and closers. Refrigerant leaks are located and brazed, pressure tested with nitrogen, evacuated, and weighed back in to the manufacturer's charge.

Common Questions
What temperature should a walk-in freezer hold?
0°F or colder for safe frozen product storage. Many operations target -5°F to -10°F to give themselves margin during heavy door traffic or a delivery day.
Why does my walk-in freezer keep icing up?
Almost always a defrost issue — a burned-out heater, a failed termination sensor, or a defrost cycle set too short — or humid air entering past a bad door gasket. Both need to be corrected or the ice returns within days.
There is ice on the floor by the door. What causes that?
Usually a failed door frame heater or threshold heater, or a frozen condensate drain line backing water into the box. It is a safety hazard as well as a symptom, so it should be fixed quickly.
