Evaporator coil fully iced
Failed defrost heater, timer or termination switch. The coil must be cleared and the defrost circuit repaired or it will happen again.

Walk-In Freezer Repair, Maintenance & Replacement
Low-temperature systems are less forgiving than coolers. A walk-in freezer that drifts above 0°F risks product quality, and a failed defrost cycle can turn an evaporator into a block of ice within a day. We service walk-in freezers from restaurant boxes to large freezer rooms in food processing and cold storage facilities.

Freezer work requires attention to defrost design, drain heaters, door heater circuits and the low-temperature compressors that carry the load. We carry parts for the common failures and understand how to work in a freezer without exposing product.

Diagnostics
Common failures and what they mean
Freezer floor or door frame icing
Door heater failure, worn gaskets or a pressure relief port stuck. Ice on the floor is a serious safety hazard.
Compressor failing repeatedly
Liquid floodback after defrost, low airflow or oil return issues on long line runs. We find the root cause.
Temperature rising slowly over weeks
Gradual refrigerant loss, condenser fouling or a compressor losing capacity. Trending catches this early.
