INTERNATIONAL PRODUCT LIABILITY POLICY (as of 11/4/2011)
Field service engineers are authorized to make an initial assessment. If in the engineer’s judgment the damage is the result of a product
defect, the product would be removed and returned to the importer in an unaltered condition. The importer would then be authorized to
permanently replace the end-user’s product at no cost to the end-user. The importer will notify U-Line and initiate a discussion regarding
disposition along with holding the product unaltered for evaluation.
If in the engineer’s judgment, the damage is the result of installation, the end-user would be so notified and the correction would be made
by the engineer or installer without requiring removal of the product. Any claim for damages should be directed to the original installer of
the product.
Any U-Line product involved in an alleged property damage claim must remain unaltered and unrepaired, for evaluation. No service
or repairs should be performed on any product suspected to be involved in property damage. If a product has been
altered or repaired in the field prior to the evaluation, any claim for damage may be declined. The product will be held
(unaltered) at the importer for disposition until notified by U-Line.
To complete the damage claim process for the end-user, the importer must obtain the following and forward to U-Line at the email
intl@u-line.com:
1. Pictures of the product, installation and any alleged property damage.
2. Inquire when the problem first appeared, any prior problems with the product and provide a brief description of the alleged damages.
3. To expedite the claim process, two damage repair estimates will be needed.
4. Reference the Return Authorization (RA) number and end-user name when providing this information.
If a product is returned to the importer, the importer will work with U-Line to facilitate the evaluation. U-Line reserves the right to
evaluate the product and will provide written (via email) approval for any person performing this evaluation. No field service engineer is
authorized to perform this evaluation without approval from U-Line. When a Return Authorization Number is issued, and the
product has been boxed in a U-Line carton, importer should be contacted and then will make arrangements for shipping, or designate a
truck line to have the product shipped freight collect to the importer.
If the evaluation finds the product to be defective, the damage claim will be reviewed by the U-Line Customer Assurance Department.
If the evaluation finds the product not to be defective, all claims for damage will be declined.
When a product evaluation is needed, it is the end-user’s responsibility to assure that the product is released for evaluation. If the end-user
fails to do so, or has the product repaired in the field prior to the evaluation, any claim for damage will be declined.

General Information
Thermistor Info
There are 5 thermistors used with the 3090 models.
• Left Zone Thermistor - Located on the right hand wall in the left
zone and is used to maintain temperature.
• Right Zone Thermistor - Located on the right hand wall in the
right zone and is used to maintain temperature.
• Left Evaporator Thermistor - Located on the back of the
evaporator plate in the left zone and is used during defrost.
• Right Evaporator Thermistor - Located on the back of the
evaporator plate in the right zone and is used during defrost.
• Ambient Thermistor - Located in the base of the unit on the
condenser and is used to monitor ambient air temperatures.
Viewing Temperature
Note: The display shows set point NOT the actual temperature.
The 3000 series is equipped with an advanced electronic display and
control. Thermistor readings can be obtained through both the
customer and service menu. The customer menu will display readings
while using offset calculations. It is important to note that the system
will use these adjusted readings when determining cooling and
defrost cycles. The service menu will display the actual thermistor
reading while disregarding offsets.
Customer Menu
To view the adjusted temperature of each available thermistor, follow
the steps below.
1. Initiate the customer menu by holding Select
2. Use Down to scroll to “Actual Temperatures”.
3. Press select .
4. Use Up or Down to scroll through available information.
Service Menu
To view the actual temperature without having the offsets taken into
consideration, follow the steps below.
1. Initiate the service menu by holding both up

Thermistor Calibration
While thermistors generally do not require calibration, over time
contact corrosion and or element wear may make calibration
necessary.
Calibration
To calibrate a thermistor one must first prepare an ice water of
crushed ice and water in a suitable container. Allow the ice water
temperature to stabilize for at least 5 minutes before beginning.
NOTICE
Offsets are preset at the factory to efficiently maintain
product temperature. If modifying offset, existing values
must be taken into consideration.
NOTICE
Customer Care must be notified before any changes are
made to factory set offsets. Failure to notify Customer Care
will void the warranty.
1. Enter the service menu and record existing offset values for each
thermistor to be calibrated. See page 12. Some models have a
factory offset setting of 0.
2. Change offset of each thermistor to be calibrated to 0.
3. Enter “Actual Temps” through the
“Viewing Temperature”.
4. Submerge the thermistor in the ice
out through the menu should be 0°C (32°F). If different, record
difference.
5. Enter “Offsets” through the service menu and set the value
recorded in step 4 to the thermistor to be calibrated.
6. Enter “Actual Temps” through the
temperature readout should now be 0°C (32°F). If the readout is
still incorrect reset the offset to 0 and perform steps 4 & 5 again.
7. Enter the “Offsets” menu and add the value recorded in step 1 to
the new offset setting. For example, if after the ice
of 1 was needed and the existing offset value recorded in step 1
was -2 the new offset value would be -1. If the calculated value is
outside the maximum range capable in the offset menu the
thermistor must be replaced. The offset menu has a maximum
range of -5°C through 5°C.

Fan Delay
The Fan Delay menu option allows the modification of fan run times
during and after a cooling cycle. In order to allow time for the
evaporator to properly cool, the evaporator fan is delayed from
starting with the cooling cycle for a given amount of time. In order to
remove as much warmth as possible from the cabinet, the evaporator
fan will continue to run at the end of the cooling cycle for a given
amount of time.
Fan Delay On=
“Fan Delay On” is the amount of time in minutes the fan will be
delayed from starting from the beginning of a cooling cycle.
Fan Delay Off=
“Fan Delay Off” is the amount of time in minutes the fan will
continue to run at the end of a cooling cycle.

Convection Cooling
All 3000 series units are 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. See “Fan
Delay” on page 14.
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 any condensation that may have appeared on
glass doors and shelves.
Note: If the unit is set to sabbath mode, the evaporator fan will no
longer respond to the state of the door switch.
In order to operate efficiently, the evaporator fan blade and vents
should be unobstructed and free of any dust buildup.
Evaporator Fan Replacement
Should the evaporator fan need to be replaced follow the steps
below.
1. Remove any product from the unit.
2. Disconnect power to the unit.
5. Remove insulating foam from refrigerant line pass-through hole.
6. Remove internal shelving, bins, or wine racks.
7. Remove shelf clips, rack, or bin mounting rails.
8. Remove thermistor cover.
9. Remove two evaporator plate screws from top of evaporator
plate.
10. Grasp evaporator fan shroud and gently pull plate away from the
rear of the unit.
11. While pulling the evaporator plate clear of the unit, it may be
necessary to use your free hand to manipulate the fan plug end
through the pass-through hole.
12. Remove the 4 screws mounting the fan shroud to the evaporator
plate.
3. Remove upper back panel.
4. Disconnect fan electrical connection

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 power on, follow the flow chart below to help
diagnose the issue. It is important to first verify the unit is not simply
set to sabbath mode.
Testing The Main Control
If the main control is suspected of being faulty, the following
procedure should be performed to verify main control for
functionality.
Relay & DC Outputs
One of the primary functions of the main control is to operate the
multiple relay and dc outputs during each cycle. Verify proper
operation of these relays using the following procedure.
1. Enter “Relay Toggle” through the service menu.
NOTICE
Frequently toggling the compressor relay could force the
compressor into overload. The compressor will
automatically deactivate during an overload and will remain
deactivated until the overload switch cools. This could take
some time. It is important to allow the compressor at least
5 minutes off time between relay cycles.
2. Toggle the relay. Its related component should activate / deactivate
with the switching of the relay. If it does not, see “Component
24
Te s ti n g ” on p a g e
Inputs
The main control monitors a number of thermistor inputs and switch
states during operation. It would be unlikely that an error in reading
an input would be at the board level. Always attempt to replace the
faulty switch or thermistor input with a known working sample to
verify proper board operation.
.
Other Suspected Main Control Faults
If other components have been ruled out as being faulty but the unit
continues to have operating issues, it is most likely due to a
configuration error. Configuration errors can be cleared by restoring
the unit to its factory default setting. Factory defaults may be
restored through the service menu. See page 13.
CAUTION
!
Precautions must be taken while working with live electrical
equipment. Be sure to follow proper safety procedures while
performing tests on live systems.

Component Testing
Frequently toggling the compressor relay could force the
compressor into overload. The compressor will
automatically deactivate during an overload and will remain
deactivated until the overload switch cools, regardless of
relay and voltage state.
If the compressor is suspected of being faulty it is important
to verify all copper tubing, dryers, capillary lines,
evaporators and condensers are free from kinks, excessive
bends or blockages. A restriction in any of these
components would force the compressor to overload,
making it appear as if it is faulty.
If a component is suspected as being faulty, follow the
troubleshooting steps below to help isolate the cause.
1. Initiate Self Test Mode, address any current errors before
beginning component testing.
2. Activate the component’s relay or DC output through “Relay
Toggle” under the service menu.
3. Test for voltage at the component.
Voltage Present
If voltage is present and the component does not function, suspect a
faulty component. If the component being tested is the compressor,
make certain it is not overloaded by disconnecting power to the unit
for at least 15 minutes and re-testing.
No Voltage Present
L1 Pin J4-4 Pin J4-9 8-12 DC < 7 DC
L2 Pin J4-5 Pin J4-10 8-12 DC < 7 DC
If no voltage is present check for voltage at the relay / DC output.
Reference the diagram for component relay / DC output pins. If
voltage is present, suspect a faulty component cable. If voltage is not
present at the relay / DC output, cycle the power to the unit and retest. If voltage is still not present, suspect the main control of being
faulty.
Component Testing Example
Below is an example of how to properly test a component for
functionality. The left zone evaporator fan is used.
Condition
Customer complains of the unit not cooling properly. The main
screen of the display lists an error “L Temp Hi 12H+”. The
compressor seems to be functioning properly, however the left zone
evaporator fan does not activate after a door cycle.
In the above case it would be wise to test the evaporator fan for
functionality.
Te s t i n g
1. Check “Self Test” for any additional errors that may be current.
2. Visually examine the fan through the fan cover. Note any ice
buildup. In this case no ice buildup was noticed. The fan appeared
as if it could spin freely.
3. Enter “Relay Toggle” and manually activate FAN1.
4. Check for fan operation. In this case the fan does not operate.
5. Remove the upper and lower back panel from the refrigeration
unit.
6. Ensuring the DC output is still active,
use a meter to check voltage at the fan
power connection point. In this instance
no voltage is present.

8. Confirming that the board is sending voltage, the cabling between
the board and fan is inspected for damage. In this case some
damage is noted.
9. The fan cable harness is replaced, and the fan DC output is tested
again. It is noted the fan now spins freely.
10. The unit is then monitored for proper operation and any further

Compressor Information
Cooling process
Refrigerant is pumped from the compressor to the condenser as a
high pressure, high temperature vapor.
As the refrigerant cools in the high pressure condenser, the vapor
condenses to liquid. During this phase change, a great amount of heat
is rejected with the help of the condenser fan.
The liquid then flows through the open solenoid valve to the dryer
where it is strained and filtered.
From the dryer, the refrigerant flows through the capillary tube which
meters the liquid refrigerant to the evaporator.
The pressure of the refrigerant is reduced to the evaporating or low
side pressure.
The reduction of pressure on the liquid refrigerant causes it to boil
or vaporize until it reaches saturation temperature. As the low
temperature refrigerant passes through the evaporator coil, it
continues to absorb a lot of heat, causing the boiling action to
continue until the refrigerant is completely vaporized. It is during this
phase that the most heat is absorbed (the cooling takes place) in the
refrigerator.
The refrigerant vapor leaving the evaporator travels through the
suction line to the compressor inlet. The compressor takes the low
pressure vapor and compresses it, increasing both pressure and
temperature. The hot, high pressure gas is pumped out the discharge
line and into the condenser. The cycle continues.
Compressors
DANGER
!
Electrocution can cause death or serious injury. Burns from hot
or cold surfaces can cause serious injury. Take precautions when
servicing this unit.
• Disconnect the power source.
• Do not stand in standing water when working around
electrical appliances.
• Make sure the surfaces you touch are not hot or frozen.
• Do not touch a bare circuit board unless you are wearing
an anti-static wrist strap that is grounded to an electrical
ground or grounded water pipe.
• Handle circuit boards carefully and avoid touching
components.
To measure the start winding resistance, measure across the C and S
pins.
To measure the run winding resistance, measure across the C and R
pins.
Also check S to R and you should get the sum of the run and start
windings.
To ensure the windings are not shorted, check the S and R to ground.

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. In an ice
water (0°C / 32°F) resistance should measure 16.1 kilohms,
Thermistor Failure
Zone Thermistors
If a zone thermistor fails, the unit will continue to operate the
zone on a preset time interval of 10 minutes on and 30 minutes
off. The unit will otherwise operate normally. The error will be
displayed on the main display and “Self Test” and logged in “All
Errors”.
Evaporator Thermistors
If an evaporator thermistor fails, the unit will rely on a preset
defrost timer during defrost cycles. The unit will otherwise
operate normally. Evaporator thermistor errors are hidden from
the display and recorded in “All Errors” and displayed in “Self
Te s t” m o de s .
Ambient Thermistor
The ambient thermistor is mainly used for diagnostics. If the
thermistor fails, the unit will operate normally.
Reed Switch
A reed switch is used to monitor door state. The switch side for each
zone is mounted under the cabinet and the magnet is mounted to the
cable arm of each respective door. When the door is closed magnetic
force pulls the reed to its contact and closes the circuit which turns
the light and display off. When the door is open the reed pulls away
from the contact and opens the circuit. If the door(s) are left open
for longer than 5 minutes, the switch will trigger an error code and
set an audible warning.
