A commercial freezer that is not freezing is most often caused by a dirty condenser, a defrost system failure causing heavy ice, worn door gaskets, a failing evaporator fan, or low refrigerant from a leak. Clean the condenser, check the door seals and look for excessive frost on the coil; if the temperature keeps rising, call for priority commercial refrigeration repair to save your product.
Common causes
- Dirty condenser coil
