Extremely Thin at Evaporator OutletThere is no ice, or a considerable lack of ice formationon the outlet of the evaporator.Examples: No ice at all at the outlet of the evaporator,but ice forms at the inlet half of the evaporator. Or, theice at the outlet of the evaporator reaches the correctthickness, but the outlet of the evaporator already has1/2" to 1" of ice formation.Possible cause: Water loss, low on refrigerant,starving TXV, hot water supply, faulty float valve, etc.Extremely Thin at Evaporator InletThere is no ice, or a considerable lack of ice formationat the inlet of the evaporator. Examples: The ice at theoutlet of the evaporator reaches the correct thickness,but there is no ice formation at all at the inlet of theevaporator.Possible cause: Insufficient water flow, flooding TXV,etc.Spotty Ice FormationThere are small sections on the evaporator wherethere is no ice formation. This could be a single corner,or a single spot in the middle of the evaporator. This isgenerally caused by loss of heat transfer from thetubing on the backside of the evaporator.No Ice FormationThe ice machine operates for an extended period, butthere is no ice formation at all on the evaporator.Possible cause: Water float valve, water pump,starving expansion valve, low refrigerant charge,compressor, etc.Part Number 80-01111-9 7/10 107
