Why your Atosa commercial freezer is not freezing
Here's how not freezing typically presents on a Atosa commercial freezer: freezer compartment stays above 0°F. Common causes: defrost thermostat, evaporator fan, sealed-system leak. On this platform it's most often defrost thermostat or heater failure. Left unaddressed, food or stock can spoil within hours.
Most likely causes
- A clogged defrost drain
- A weak or failing compressor
- Blocked air vents between compartments
- Failed temperature sensor
Known Atosa commercial freezer weak points
- evaporator and condenser fan-motor failures
- door gasket and self-closing hinge wear
- thermostat/temperature-control drift
- gas range pilot, igniter and valve issues
Quick check — and when it's not DIY
Worth checking yourself first: listen for the evaporator fan running when the door's closed, since a silent fan is a common first sign. Also, confirm the thermostat setting, that the door seals fully, and that vents inside aren't blocked by over-packed items. Past that point, 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
We trace the not freezing on your Atosa commercial freezer to its source instead of throwing parts at it. 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. The quote is flat, approved before we start, and every repair carries our warranty.
