Reduced ice production is usually caused by: mineral scale buildup on evaporator plates reducing heat transfer, dirty condenser coils reducing refrigeration efficiency, warm ambient temperature in the equipment room, low refrigerant levels, or water flow problems. The fix for scale buildup is professional cleaning and descaling. Other issues require a technician. Never ignore reduced production — it often progresses to complete failure.

Walk-in door gaskets typically last 2-4 years and should be inspected every 6 months. Signs of failing gaskets: visible tears or cracks, frost buildup near the door frame, condensation on the door frame, noticeably warmer temperatures near the door, or the door not staying closed. A failing gasket forces the compressor to work harder, increasing energy costs and reducing equipment life.

Chemical dispensing problems are typically caused by: clogged or faulty chemical pumps, incorrect dilution ratios, empty chemical containers, broken injection lines, or control board issues. In low-temperature machines, proper chemical concentration is essential for sanitization — test strips should verify concentration after every repair. Many chemical distributors offer free testing; alternatively, a technician can verify and repair the dispensing system.
