Walk-in Cooler & Freezer Repair
Diagnostics and repair for walk-in coolers, walk-in freezers and remote condensing units — within KONGRA's legal license scope.
Walk-in problems we diagnose
Warm room, ice buildup or a stopped fan?
Temperature rises during service
Compare the room-temperature trend with deliveries, door use and production hours. Air entering through the door, airflow restrictions and refrigeration-system faults can produce similar complaints. A high display reading alone does not identify the compressor.
Ice returns after defrost
Record where ice appears and whether it clears during the normal cycle. The technician matches defrost, termination, airflow and drainage checks to the evaporator and controls fitted. Walk-in systems may use air, electric or hot-gas defrost; the same procedure does not apply to all of them.
Fan stopped or airflow weak
Note whether the fan stops only during defrost or remains stopped during cooling. That timing helps distinguish a control sequence from an electrical or mechanical problem. Leave guards and electrical covers in place for the service visit.

Visible buildup around the fan and airflow area; condition documented, not a claimed root cause.
Imperial Brown UDS-4 walk-in
A field data plate documented an Imperial Brown door/panel assembly marked UDS-4. Imperial Brown's own walk-in documentation explains that UDS-4 is a panel-construction designation for four inches of urethane foam; it is not the refrigeration-system model or a substitute for the order number. For parts and refrigeration diagnostics, the evaporator, controller and condensing-unit plates are identified separately.
Legacy Duracold walk-in
Another field data plate documented a Duracold commercial refrigerator/freezer enclosure marked Model #1F. The enclosure plate is useful for box, door and panel identification, but refrigeration service still depends on the installed evaporator, fan, controller and condensing-unit data.
Common walk-in issues documented by Imperial Brown
Prepare for service and prevent repeat interruptions
Send the evaporator and condensing-unit models, the controller message, the temperature trend and when the problem started. Tell us which equipment can be taken out of service and your available access window. Protect affected stock using your facility's food-safety procedure. Recurring door, coil, fan and drain concerns can be included in a preventive-maintenance plan; inspection findings determine the scope.

Frequently asked questions
Do you service walk-in coolers and freezers?+
Yes. Walk-in coolers, walk-in freezers, remote condensing units and evaporator coils used in restaurants, groceries and food service, including selected Imperial Brown and legacy Duracold walk-ins.
Is Imperial Brown UDS-4 the refrigeration-system model?+
No. Imperial Brown documentation says UDS-4 identifies a four-inch urethane panel construction, not the order or condensing-unit model. The refrigeration components must be identified from their own data plates.
Can you service a Duracold walk-in?+
Yes, selected legacy Duracold walk-in boxes can be evaluated. The walk-in panel/box data plate and the separate evaporator, controller and condensing-unit plates are all needed because the enclosure brand does not identify the complete refrigeration system.
Do you handle refrigerant work?+
KONGRA provides diagnostics and coordinates certified contractors for refrigerant and sealed-system work. The scope, responsible provider and price are confirmed before work begins.
