Walk-In Cooler Not Holding Temp? What to Check Before You Lose Product

Air-Exx services walk-in coolers and freezers, ice machines, reach-ins, prep tables and the rooftop units that cool the dining room, for restaurants and businesses across Mohave and Yavapai counties. Most of the calls we get start the same way: "It was fine yesterday."

Five checks your staff can do safely

1. Door and gaskets. Make sure the door closes on its own and the gasket seals all the way around. A torn gasket, or a door propped open during deliveries, lets warm air in all day.
2. Evaporator coil. If the coil inside the box is frosted solid or iced over, the unit cannot move cold air. Don't chip at it. Call us.
3. Condenser coil. The outdoor or top-mounted condenser collects kitchen grease and Arizona dust. A clogged condenser is one of the most common reasons a cooler can't keep up when it's hot outside.
4. Loading. Hot food loaded straight in, or cases stacked against the evaporator fan, will push the box temperature up.
5. Power. Check for a tripped breaker or a disconnect that got bumped.

What to write down before you call

Note the box temperature and the time, whether the compressor and fans are running, any ice you see, and any alarms or codes on the controller. That helps the tech bring the right parts the first time.

When to call right away

Call if the box is above 41 degrees and climbing (the cold-holding limit in the FDA Food Code), if there is ice on the coil, if the compressor runs nonstop or short-cycles, or if you see a water or refrigerant leak. Phones are answered 24 hours a day, Monday through Saturday, and we dispatch an on-call technician. Closed Sunday.
