Troubleshooting - Extended

CAUTION

!

Never attempt to repair or perform maintenance 
on the unit until the main electrical power has 
been disconnected from the unit.

SPECIFIC ERRORS AND ISSUES

The advanced diagnostic capabilities of the electronic 
controls utilized on the 1, 3, and 5 Class units allow for 
easy and thorough troubleshooting.

Navigation of the control is the key and is explained in 
the CONTROL OPERATION section of the manual, along 
with control button layout, control function descriptions, 
a service mode menu and service menu selection 
explanations.

Verification of temperature and thermistor performance can 
be identified by directly viewing thermistor readings in the 
service mode.

Included in this section are some diagnostic tips and of 
course, if additional help is required, please contact the 
U-Line Corp, “Customer Care Facility” at +1.800.779.2547 
for assistance.

NORMAL OPERATING SOUNDS

All models incorporate rigid foam insulated cabinets to 
provide high thermal efficiency and maximum sound 
reduction for its internal working components. Despite 
this technology, your model may make sounds that are 
unfamiliar.

Normal operating sounds may be more noticeable because 
of the unit’s environment. Hard surfaces such as cabinets, 
wood, vinyl or tiled floors and paneled walls have a 
tendency to reflect normal appliance operating noises.

Listed below are common refrigeration components with a 
brief description of the normal sounds they make. NOTE: 
Your product may not contain all the components listed.

•  Compressor: The compressor makes a hum or pulsing 

sound that may be heard when it operates.

•  Evaporator: Refrigerant flowing through an evaporator 

may sound like boiling liquid.

•  Condenser Fan: Air moving through a condenser may 

be heard.

•  Automatic Defrost Drain Pan: Water may be heard 

dripping or running into the drain pan when the unit is 
in the defrost cycle.

Solenoid Valves: An occasional clicking sound may be 
heard as solenoid valves are operated.
