Failed defrost
Bad defrost timers, controls, heaters and termination switches that let the coil turn into a block of ice.
Typical all-in: Est. $385–$785
Ice on the evaporator, floor or ceiling means something is letting warm, wet air in or the defrost isn't working. Left alone, it turns into a warm freezer.

Quick answer
A walk-in freezer ices up when the defrost system fails (timer, heaters or termination switch), the drain line freezes, the evaporator fan stops, or the door doesn't seal and warm air gets in. First check the door and gasket, look for a frozen drain, and confirm the evaporator fans run. Typical repairs are estimated at $385–$885 for defrost, drain heater and door work. Quoted in writing first, $199 commercial trip fee waived with the repair, after-hours emergency service available.

If your equipment is down right now
If the box is warming, move product to another freezer and log temperatures.
Make sure the door closes and seals all the way. Ice on the frame means air is getting in.

FAQs
Usually a defrost failure, a stopped evaporator fan, or warm air from a door that doesn't seal. The cause has to be fixed or it will ice up again.
A frozen or blocked drain line, often from a failed drain heater, lets defrost water freeze in the pan and drip onto the floor.
You can turn it off to thaw as a short-term step, but product must be moved first and the cause still needs repair.
Defrost, drain heater and door repairs are usually estimated at $385–$885. You get a written quote first, and the $199 trip fee is waived with the repair.
