SYSTEM REPAIR
Ensure no residual R-600a refrigerant is left within the system prior to
repair (simple venting is not sufficient).
Evacuate and charge with dry nitrogen for leak checks.
Repair leaks or replace system parts as required.
When re-brazing, the system must be purged with dry nitrogen and at least one
access point open to the atmosphere.
When re-brazing, proper ventilation is required along with constant monitoring
for the presence of R600a refrigerant.
The filter dryer must be replaced any time the sealed system is serviced.
No system should be open to the atmosphere for longer than 15 minutes to avoid
moisture migration into the system components.
LEAK DETECTION
After removal of the R-600a, the unit can be charged with dry nitrogen or
helium.

nitrogen/helium leaks.
Never use a halide torch or lighted match to check the system for leaks at any
time.
The high side of the refrigeration system (compressor discharge to outlet of
drier) must be leak tested with the compressor running.
The low side of the refrigeration system (evaporator, compressor and suction
line) must be leak tested with the compressor off (equalized pressure).
RECHARGING
No air is ever to be allowed inside the refrigeration system (R-600a
refrigerant or dry nitrogen only).
Never use a torch on a fully charged refrigeration system.
Install a Schrader Type access port on the compressor process stub.
Evacuate the system to 100 microns prior to charging.
Weigh in the R-600a charge using a refrigerant scale. (run compressor an extra
two minutes to clear the charging hoses).
Seal the Schrader Type access port, a proper cap and seal must be used to
close the system.
SUMMARY

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; if additional help is
required, please contact the U-Line Corp, “Customer Care Facility” at
+1.414.354.0300 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.

MAIN CONTROL
The main control board is very robust and is rarely the cause of system
issues. It is important to fully diagnose the board for any suspected failures
before attempting to remove the board for replacement or service. Follow the
guidelines below to fully test and diagnose the main control.
Power Fault
If the unit does not (or seems to not) power on, follow the flow chart below
to help diagnose the issue. Before beginning it is important to first verify
the unit is not simply set to sabbath mode.
CAUTION
Precautions must be taken while working with live electrical equipment. Be
sure to follow proper safety procedures while performing tests on live
systems.
PLUNGER SWITCH
A plunger switch is used to monitor door state. When the door is closed it
comes into contact with the plunger which closes a circuit which turns the
light and display off. When the door is open the plunger moves outward and
opens the
circuit. If the door is left open for longer than 5 minutes the switch will
trigger an error code and set an audible warning. Control Operation-

Thermistors
Thermistors are used for various temperature readings.
Thermistors provide reliable temperature readings using a resistance which
varies based on surrounding temperatures. If a faulty thermistor is suspected
it may be tested using an accurate ohmmeter.
USER GUIDE
Thermistor
Both thermistors in the unit are identical. If a thermistor is suspected of
being defective, the resistance can be verified. Place the thermistor in an
ice water bath, the resistance should read 16.1k Ohms +/-5% on your meter.

Defrost
This unit defrosts, by default, every 12 hours of compressor runtime for 45
minutes. If you have verified that the unit does not have an ambient air leak,
refer to the Control Operation – Service section and adjust unit to defrost
every 9 hours for 60 minutes. Also, adjust the #2 thermistor to -4 instead of
0.
Remove Fan and Cover
CONVECTION COOLING
This unit is equipped with an advanced convection cooling system. Convection
cooling stabilizes cabinet temperature, cools product faster and increases
energy efficiency.
Evaporator Fan
The evaporator fan is responsible for circulating warm air from the
refrigeration zone, past the evaporator and back into the refrigerated zone.
The evaporator fan is factory set to have a 1 minute delay at the beginning of
a cooling cycle. This delay gives the evaporator time to cool properly before
warm air is passed over it. The fan will continue to run for an additional 2
minutes at the end of a cooling cycle. Fan delay times can be modified through
the service menu.
Evaporator fan operation is also determined by door switch state. If the door
switch circuit opens, the fan will stop. When the door switch circuit is
closed the fan will either continue running with the cooling cycle, or if not
currently cooling, the fan will run for 1 minute to circulate air and clear
