4. Spotty Ice Formation

There are small sections on the evaporator where

there is no ice formation. This could be a single corner

or a single spot in the middle of the evaporator. Refer

to Evaporator Tubing Routing on the previous page to

determine your specific models tubing confirmation.

This is generally caused by loss of heat transfer from

the tubing on the backside of the evaporator.

5. No Ice Formation

The ice machine operates for an extended period, but

there is no ice formation at all on the evaporator.

Possible cause: Water fill/float valve, water pump,

starving expansion valve, low refrigerant charge,

compressor, etc.

Important

Q1400C & QDUALC ice machines have left and

right expansion valves and separate evaporator

circuits. These circuits operate independently from

each other. Therefore, one may operate properly

while the other is malfunctioning.

Example: If the left expansion valve is starving, it

may not affect the ice formation pattern on the right

side of the evaporator.
