Walk-in Freezer Repair in Colorado Springs

Most walk-in freezers are set somewhere between −10°F and 0°F. Once the box drifts above that, ice cream softens first and the rest of the product follows. Best Pro repairs walk-in freezers for restaurants, grocery and convenience stores, ice cream shops, bakeries, caterers and food producers across Colorado Springs and in Monument.

Most freezer trouble starts at defrost

A freezer coil picks up frost every time the door opens, so the system has to melt it off several times a day. That job adds parts a walk-in cooler doesn’t have, and they cause most freezer calls:

• Defrost heaters, the termination thermostat and the timer or controller. When one of them fails, frost turns into a solid block of ice on the coil, air stops moving and the box warms up while the compressor keeps running.
• The drain line heater. Defrost water has to leave the box before it refreezes. When the heater on the drain line fails, the line freezes, water backs up into the pan and the coil, and ice spreads onto the floor and the shelves.
• The fan delay. After defrost, the evaporator fans should wait until the coil is cold again. If they start too early, they blow warm, wet air into the box, and frost forms on the ceiling and on the product.

Doors, frames and the pressure relief port

Heater wires in the door frame keep the gasket from freezing to it. When they burn out, the door sticks, ice builds up at the threshold and the gasket tears. A freezer also needs a heated pressure relief port: warm air comes in while the door is open, and after it closes that air cools, shrinks and pulls a vacuum on the box. If the port ices over, the door is hard to open for a while after every closing, and the panels take the strain. Closers, hinges and strip curtains matter more on a freezer as well — a door that doesn’t shut by itself puts ice on the coil within hours.

Cold snaps and hot afternoons

Most condensing units here sit on the roof or behind the building. On single-digit nights, head-pressure control has to keep the system fed, and the crankcase heater has to keep liquid refrigerant out of the compressor during the off cycle; if either fails, the system short-cycles, ices the coil or damages the compressor. In July it’s the other way round: a condenser coated with cottonwood fluff and dust runs hot in the thin air, and the compressor trips on overload in the afternoon. Our walk-in cooler repair page explains the winter side in more detail.
