NorLake appliance repair for walk-in coolers and freezers, including Kold Locker, Fast-Trak and Fineline boxes. A walk-in that will not hold temperature puts your food and your next inspection at risk. We treat that as urgent and try to arrive the same day. Approve the repair and the $149 business diagnostic is off the bill.



We repair NorLake walk-in coolers and freezers. That includes quick-ship Kold Locker boxes, semi-custom Fast-Trak units and custom Fineline walk-ins. We also service NorLake refrigeration systems like Capsule Pak and Split-Pak, and LogiTemp controllers. Doors, heaters, fans, coils and compressors are all part of the job.
NorLake has made walk-ins since 1947. It started in a garage in Hudson, Wisconsin, and is still based there. Kold Locker boxes come in indoor and outdoor models, as coolers or freezers.
A warm walk-in is an emergency. You have a box full of product and a clock running. Here is how we track it down.
First, the door. A torn gasket or a door that does not close on its own lets warm air in all day. On freezers, the door frame has a heater wire to stop ice from forming. If that heater fails, the door freezes shut or will not seal.
Next, the evaporator. This is the coil and fans inside the box. If the coil is a block of ice, defrost has failed. LogiTemp controls run a reverse cycle defrost on some systems, so we check that sequence too. A bad fan motor can also leave half the box warm.
Then the condensing unit, the part outside or on top that sheds heat. A dirty coil, a failed fan or a weak compressor all show up here. If the system is low on refrigerant, we find the leak before we refill it.
Outdoor units face sun, rain, leaves and snow. In a Houston summer the condensing unit may run all afternoon. In a Chicago winter, a remote unit can have trouble starting in deep cold. We check roof seals, drain lines and the condensing unit's location. Sometimes a simple shade or a cleared fence line does as much as a new part.
Pick up the phone as soon as the temperature climbs. We run same-day visits for most walk-in calls. The tech checks the whole system and hands you one price before any work.
Say yes and you will not pay the $149 commercial diagnostic. We use genuine OEM parts, and our repair warranty covers the job. If a compressor or controller needs ordering, the return date is set on the spot. We can also suggest ways to hold product until then. Every tech who visits is licensed, insured and background screened.
Almost always. The panels are insulated with polyurethane foam that lasts a long time. The parts that fail, like fans, heaters, controls and compressors, can all be replaced. Swapping a whole walk-in is a big job and a lot of downtime.
The exception is damaged panels. If water has soaked the foam or the floor has rotted, the box loses its seal. Then we will talk with you about replacing sections. Most of the time, though, the box itself is fine and only the parts need work.
Our walk-in techs cover Chicagoland, Houston, Pasadena and greater Los Angeles, Northern Virginia and the District. Our freezer repair and cooler repair pages have more on cold storage.
