Quick check — and when it's not DIY
Before you call anyone, confirm the thermostat setting, that the door seals fully, and that vents inside aren't blocked by over-packed items. Once you've ruled that out, it's usually a defrost heater, sensor, or sealed-system fault, and diagnosing those needs a multimeter and refrigeration training, not guesswork.
How we fix it
Our technician runs a full diagnostic on your Atosa walk-in freezer and isolates the exact cause before quoting. OEM parts are available through Atosa distributors but less ubiquitous than legacy brands; gas cooking work needs a licensed technician and sealed refrigeration needs an experienced technician. Most not freezing jobs finish same-day, at a flat price, under our warranty.
