A walk-in freezer that won’t hold temperature can spoil a full box of product before the next delivery. Best Pro repairs walk-in freezers for restaurants, grocery stores, ice cream shops, warehouses and food producers across the Denver metro area.
Why walk-in freezers fail
A freezer runs its evaporator coil well below freezing, so most of its problems have to do with ice:
- Defrost failures. The coil has to be cleared of frost several times a day, usually by electric heaters controlled by a timer or an electronic controller. When a heater, the timer or the defrost termination sensor fails, ice builds up until no air gets through the coil and the box warms up.
- Frozen drain line. Melt water from each defrost leaves the box through a heated drain line. If the drain line heater fails, the line freezes, water backs up into the pan and refreezes on the coil — the next defrost makes it worse.
- Door heaters. A heater wire in the door frame keeps the gasket from freezing to it. When it burns out, the door freezes shut or the gasket tears when someone pulls it open, and the torn gasket lets in moist air that turns into more ice.
- Evaporator fans. The fans inside the box work in cold, icy air. A failed motor or a blade frozen in ice stops the airflow, so the coil ices up even when the defrost works.
The condensing unit
Outside the box, a walk-in freezer has the same weak spots as any refrigeration system: a dirty condenser coil, a failing condenser fan motor, a refrigerant leak or a compressor that overheats and trips. On a freezer these show up as long run times and a box that slowly climbs from its usual setting toward zero and above.
What we check
The technician checks box and coil temperatures, the defrost heaters, the timer or controller and its termination sensor, the drain line and its heater, the door heaters and gaskets, the evaporator and condenser fans, and the refrigerant pressures. You get the price before any work starts and a 90-day warranty on parts and labor.
If the freezer is warming up, keep the door closed and call right away: a closed, full box holds its temperature for hours, an open one doesn’t.
