How to Replace a Swing Door Heater Cable on a Walk in Cooler

Learn how to replace a swing door heater cable on a walk-in cooler or freezer door. This video provides a helpful overview of replacing the heater cable used around the door opening to help control condensation, frost, and ice in refrigerated and low-temperature applications.

Door heater cables are an important component of many walk-in cooler and freezer door systems. By providing controlled heat around the door frame, the heater helps prevent moisture from condensing and freezing where the door seals against the frame. A damaged or failed heater cable can contribute to condensation, frost buildup, ice formation, and problems with normal door operation.

Replacing a faulty swing door heater cable can help restore proper performance around the door opening and protect the gasket and sealing surfaces from excessive frost or ice accumulation. Proper operation is especially important in freezer and other low-temperature applications where temperature differences and humidity can create challenging conditions around the doorway.

This video is a useful resource for refrigeration technicians, facility managers, maintenance personnel, contractors, and walk-in cooler or freezer owners who need to replace a door heater cable or troubleshoot condensation, frost, and ice around a refrigerated swing door.
