Signs your walk-in freezer needs a repair call
Heavy ice or frost coating the walls or coil

Puddling or ice on the floor near the door
Compressor short-cycling on and off
Door won't latch or seal tight
What we check first
- Defrost timer & heater — the most common cause of heavy frost buildup
- Door gaskets and hardware — even a small gap lets in humid air that turns to ice fast
- Evaporator fan motors — frozen or failed fans stop air circulation
- Compressor and refrigerant charge — for units that run constantly without recovering temperature
Frequently asked questions
Why does my walk-in freezer have heavy frost buildup?
Heavy frost usually means the automatic defrost cycle isn't running correctly, or a door isn't sealing and is letting in humid air.
How fast does product spoil if a walk-in freezer goes down?
A well-insulated, fully loaded freezer can often hold safe temperatures for several hours if the door stays closed — but treat any freezer failure as urgent rather than waiting to see if it recovers.
