Store Freezers and Ice Merchandisers

Home › Refrigeration by industry › Convenience store refrigeration › Freezers and ice merchandisers

Frozen food and bagged ice are small categories that cause big problems when they fail: melted ice cream, bags of ice frozen into one block, and water on the floor. This page covers the freezers and ice merchandisers in convenience stores, liquor stores and markets. It is part of our convenience store refrigeration section.

What the rules say

Frozen food must be stored and displayed frozen (HSC 114018), and ice is food under the California Retail Food Code (HSC 113781). Every unit needs a readable thermometer in its warmest part (HSC 114157).

Glass door and ice cream freezers

• Frost inside the case. Doors not closing or sealing, torn gaskets, or a failed defrost system.
• Fogged glass. Freezer doors need working door and frame heaters. Fogging on the outside of the glass usually means a heater or its control has failed.
• Soft product. Dirty condenser, iced evaporator, failed fan, or product loaded over the line.
• Chest-style ice cream freezers. Lids left open, ice buildup around the rim and blocked condenser grilles near the floor.

Bagged ice merchandisers

• Bags frozen together. Temperature swings cause partial thawing and refreezing. The unit needs to hold steady, and doors must close.
• Frost and ice on the walls. Door gaskets and heaters, or moisture from bags loaded wet.
• Water on the floor. A blocked drain or a failed defrost or drain heater. See refrigeration water leaks.

If you bag your own ice, the ice machine and bin fall under the ice machine cleaning rules: clean at the manufacturer's frequency (HSC 114117). See commercial ice machine repair and ice machine cleaning and sanitizing.

Replacing a freezer

New self-contained freezers have been limited to refrigerants with a GWP under 150 since January 1, 2025 (40 CFR 84.54). ENERGY STAR certified commercial freezers are on average about 20 percent more efficient than standard models (ENERGY STAR), and the California Foodservice Instant Rebates program lists glass or solid door freezers at $50 to $100 per unit at participating dealers while funds last (program flyer).
