Walk-in cooler temperature climbing?

• Box temperature above setpoint
• Coil frozen over
• Compressor running nonstop
• Water on the floor of the walk-in
• Door won't seal or latch properly

• Iced evaporator coil from defrost failure
• Bad door gasket or damaged door
• Condenser coil fouled or fan failure
• Refrigerant undercharge or leak
• Faulty thermostat or controller

• Inspect and clear the evaporator coil
• Test defrost heater, timer, and terminator
• Check condenser fans and coil cleanliness
• Verify door gaskets and hinges
• Test control accuracy and calibration

• Move perishable product to a backup unit if possible
• Do not chip ice off the coil with sharp tools — it can puncture the tubing
• Check that the walk-in door is fully closing

If the problem keeps coming back, affects food safety, or involves the sealed refrigeration system, it's time to call in a specialist. We'll diagnose it properly and explain your options clearly.

Repair cost depends on the diagnosis, parts, labor, refrigerator type, and the specific problem. The diagnostic visit is $125 for commercial service, and that fee is credited toward completed repairs. We won't quote a final repair price until we've diagnosed the actual issue — but we'll always explain the cost before any work begins.
