Commercial Refrigerator Not Cooling?

1 Check the Condenser Coils

A leading cause of warm fridges in Memphis kitchens.

Dust, grease, and flour buildup acts like a blanket, trapping heat. If your coil is dirty, the fridge can't cool.

The Fix: Locate the condenser coil (usually bottom or top of unit). Use a stiff brush or vacuum to remove the buildup. If it's greasy, you might need a coil cleaner spray.

If the coil is packed with grease or the reach-in is still warm after cleaning, our commercial refrigeration repair in Memphis covers reach-in coolers, freezers, and prep tables.

2 The "Dollar Bill" Gasket Test

Cold air leaking out means the compressor runs non-stop until it burns out.

The Fix: Close the door on a dollar bill. Try to pull it out. If it slides out easily, your magnetic gasket is shot. Inspect the seal for rips or tears.

On a walk-in, a torn or hardened gasket also leaves condensation at the frame and frost on the evaporator; door gasket replacement and hinge adjustment are part of our walk-in cooler and freezer maintenance in Memphis.

3 Check for Airflow Blockages

Restaurants often stack boxes right in front of the intake vents or fill the shelves so full that air can't circulate.

The Fix: Ensure there is at least 6 inches of clearance around the outside intake vents. Inside, make sure produce boxes aren't blocking the fan fans.
