Whether you own a small cafe or large dining establishment, having a well-functioning commercial freezer is essential. Unlike a stove or cash register, if the walk-in breaks, you likely won’t have access to a backup, which could force you to throw away food and lose money. Below are several common issues so that you can have a refrigeration service fix them before they worsen.

When Do You Need Repairs for a Commercial Freezer?

1. Frost Buildup 

While the inside of the freezer is cold, there shouldn't be frost on your items. This occurs when warm, moist air meets the chilly environment and freezes. If frost is accumulating on the doors or walls, it may be due to a faulty door seal or defrost timer. Alternatively, the door gaskets may be broken, allowing humid air to infiltrate. Without prompt attention, the commercial freezer will need to use constant energy to replace the cold air that is escaping, increasing wear and tear and raising the utility bill.

2. Strange Smells

While lingering food smells are normal, persistent odd odors are cause for concern. A chemical or gas odor near the door most likely indicates a coolant leak. This fluid removes heat from the freezer, and without a sufficient supply, the walk-in may stop working. Alternatively, a spoiled food scent could signal the unit isn’t cooling sufficiently, allowing the inventory to rot.

3. Visible Moisture

Pooling water, leaks, or condensation typically indicates the freezer is not maintaining a low enough temperature. This could be due to a faulty door seal, refrigeration issue, or plumbing trouble. Wet floors are a safety and health hazard that could result in considerable financial loss without prompt attention. For example, employees may slip and hurt themselves when retrieving items from the commercial freezer. Also, standing moisture increases the risk of mold growth, which is a health code violation that could result in a fine.

4. Unusual Sounds

Commercial freezers usually emit a dull hum, which is the sound of the motor cooling the space. However, if your walk-in freezer is making a buzzing, knocking, or squealing noise, investigate the issue immediately. Buzzing may indicate the compressor is damaged due to motor burnout or damaged insulation. Knocking or squealing may also signal a problem with the motor, usually occurring when a component is loose.
