Reach-In Cooler or Prep Table Running Warm? 7 Checks

Cold food must stay at 41°F or below. When a reach-in or prep table runs warm, the most common cause in Las Vegas kitchens is a condenser clogged with grease and dust. Clean the condenser grille, make sure product isn't blocking the evaporator fan, check door gaskets and self-closers, close prep-table lids between rushes and look for ice on the coil. If it's still warm, the fans, controls or sealed system need a technician. We also service walk-in coolers and freezers.

7 checks you can do safely

1. Clean the condenser. Brush or vacuum the condenser fins; in a busy kitchen, every 1–3 months.
2. Free the airflow. Keep product a few inches away from the evaporator fan and vents.
3. Check door gaskets. Torn or flattened gaskets let warm, humid air in and ice up the coil.
4. Check self-closing doors. Doors left ajar during service are a leading cause of warm units.
5. Close prep-table lids. An open lid between rushes warms the pans.
6. Look for ice. Ice on the evaporator coil points to a defrost or airflow fault.
7. Check the room. Units next to fryers or ovens need ventilation clearance.

When to call a technician

• Temperature stays above 41°F after cleaning the condenser.
• Compressor cycles on and off or won't start.
• Water on the floor from a frozen or clogged drain.

Stay safe

Unplug the appliance (or switch off its breaker) before touching anything inside it, and never open a sealed refrigeration system, a gas valve or a microwave. If a code points to a part, the part has to be tested before it is replaced; we do that on the $75 diagnostic visit, credited toward the repair.
