Basic Checks
Listen

Listen to the customer's description of the problem with the icemaker. Try to understand what the
current defect is and how the unit operated before calling for service.

Listen to how the unit sounds when it runs. Often times problems can be diagnosed by sound(s)
or lack of sound.
See

Check the copper lines of cooling system, especially at the welding points. If oil is seen around
any part of the cooling system it is likely due to a refrigerant leak.

Check if the ice-making and ice-harvest cycles are normal. Too long or too short a cycle may
result in a system malfunction.

Check the water system for leaks, especially at the connections. Make sure the pump drain cap
on the rear of the unit is tight and doesn't leak.

Check the water filter (if installed.) A dirty filter needs to be replaced.

Check if the icemaker is installed according to the user's manual.

Check if the icemaker needs to be cleaned. Lack of regular cleaning will result in problems and
may cause health issues.
Touch

Touch the discharge line from the compressor and make sure it is hot. Touch the suction line and
make sure it is cool.
