Look at the front, back, top, sides, and bottom of your ice machine. Take off the front panel and look inside. What do you see?
Is the condenser coated with dust, dirt, grease, or lint? Is the evaporator coated with mineral deposits, slime, and algae? These conditions, if they exist, are definitely reducing the efficiency of the ice machine.
Not only are they reducing the ice-making efficiency of the unit, they are reducing its life expectancy too — not a very good return on your investment.
Not only is the compressor working harder with a dirty condenser, the unit is consuming more energy, and increasing cycle times as a result.
A dirty evaporator causes all kinds of other problems. Dirt or mineral buildup on an evaporator acts as an insulator and that inhibits proper heat transfer.
It is also very important to keep the water pump, water hose lines, water distribution tube, water float valve, water dump valve, and water trough area clean.
If any of these parts are clogged, they can contribute to lower efficiencies. Sometimes a water-related cause can simulate a refrigeration system diagnosis.
While you’re checking for dirt, don’t forget to look for damage and obvious signs of wear. A simple part replacement can keep the unit from going out of service when it’s most needed.
