What to do now
Keep the door closed
Every opening lets warm air in. Plan trips in and out, and move the most critical product to another unit or iced coolers.
Check the inside release first
Walk-ins have an inside door release so no one can be trapped. Make sure it works before anyone goes in, and never prop the door with product.
Food safety and refrigerant
Product held above 41°F for too long may need to be discarded under food-safety rules. Move product to working units or approved temporary cold storage, keep temperature logs, and follow your local health department’s guidance. Do not open refrigeration panels or handle refrigerant; that work requires trained, EPA-certified technicians.
Common causes
Iced-over evaporator
A blocked or iced evaporator coil inside the walk-in stops airflow. Defrost problems and door leaks are common causes.
Dirty or blocked condenser
The outdoor or rooftop condenser needs airflow to remove heat. Dirt, debris or a failed fan raises the box temperature.
Door and gasket problems
Torn gaskets, sagging doors and broken strip curtains let warm, humid air in, causing ice and warming.
Electrical or compressor failure
Tripped breakers, failed contactors and compressor problems stop cooling entirely. See commercial electrical repair.
What to have ready when you call
- Property ZIP code and business type
- Current temperature and how fast it is rising
- Whether the fans inside are running and whether there is ice on the coil
- Whether the condenser outside or on the roof is running
- Unit brand, if known
- Who can authorize work
How walk-in cooler repair usually works
- Check the box. The technician inspects the evaporator, fans, defrost, door and gaskets inside the walk-in.
- Check the condensing unit. The outdoor or rooftop unit is checked for airflow, electrical faults and compressor operation.
- Repair. Coils are defrosted and cleaned, failed fans or controls are replaced, and gaskets or doors are adjusted.
- Refrigerant. If refrigerant is low, the leak is found and repaired by a certified technician before recharging.
A walk-in that ices up repeatedly usually has a door, gasket or defrost problem. Fixing the cause prevents the next failure.

Call 833-877-1717Walk-in cooler warming questions
Why is my walk-in cooler warm?
Common causes are an iced evaporator, a dirty condenser, failed fans, a door that does not seal or a refrigerant leak.
Is it safe to go inside a walk-in?
Yes, if the inside release works and the door is not blocked. Do not go in if there is a strong refrigerant smell; ventilate and call.
Why is there ice on the walk-in coil?
Warm air from door openings, a failed defrost system or low airflow can cause ice. Turning the unit off to thaw is a temporary step; the cause needs fixing.
What temperature should a walk-in cooler hold?
Most perishable food needs to be held at 41°F (5°C) or below under the FDA Food Code. Check your local health code.
Can a walk-in cooler be repaired the same day?
Many repairs, like fans, controls and defrost parts, are done on the first visit. Compressors and some parts may need ordering.
Can I call at night or on a weekend?
Yes. You can call 833-877-1717 at any time, including nights, weekends and holidays. Whether an independent provider can come out right away depends on your ZIP code, the time and provider capacity, so availability is not guaranteed.
