1) Check if the condenser unit is running. 2) Inspect condenser coils for dirt and debris — blocked coils are a common cause. 3) Ensure walk-in door gaskets are sealing properly. 4) Check if evaporator fan is running. 5) Look for ice buildup on evaporator coils (defrost system failure). If temperature is rising significantly, move temperature-sensitive inventory and call a technician immediately — this is an emergency situation.

NFPA 96 (Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations) requires cleaning frequency based on cooking volume: monthly for solid fuel cooking (wood, charcoal); quarterly for high-volume cooking (24-hour operations, charbroiling); semi-annually for moderate-volume cooking; and annually for low-volume cooking (pizzerias, churches, seasonal businesses). Your local fire marshal may have additional requirements. Failure to comply can void your fire suppression system coverage.

Consider replacement when: repair costs exceed 50% of replacement cost, the equipment is over 75% of its expected lifespan, parts are no longer available, the equipment frequently breaks down, or energy costs are significantly higher than modern alternatives. Repair when: the equipment is relatively new, the repair is straightforward, and the total repair cost is well below replacement value. A qualified technician can help evaluate your specific situation.
