    That’s a single door reach in refrigerator.  It doesn’t have a defrost circuit.  If you are experiencing icing, check the following

    • Door gaskets
    • Thermostat setting to cold
    • Actual product temp in the morning at start up to be correct. 36 to 38F is ideal
    • Over usage. Loading hot open product or to many openings per hour
    • Door not kept closed and only opened as product is added or removed.
    • Overload. (effects air flow and thermistor sensing)
    • Verify thermostat is accurate with a known thermometer.
    • Evaporator fan is moving air and up to speed

     

    Lastly, the controller is designed to not restart till the box gets to 38 degrees to facilitate a De-icing of the evaporator every cycle of the compressor. If your temp is set to 36 to 38 degrees it should shed ice over time unless you have a air flow problem.  If ice is starting on one side and moving across you may have a refrigeration problem.  Call a licensed refrigeration tech to check .
