WARNING

SHOCK HAZARD — Electrical Grounding

Required. Never attempt to repair or perform

maintenance on the unit until the electricity has

been disconnected.

Never remove the round grounding prong from

the plug and never use a two-prong grounding

adapter.

Altering, cutting or removing power cord,

removing power plug, or direct wiring can cause

serious injury, fire, loss of property and/or life,

and will void the warranty.

Never use an extension cord to connect power to

the unit.

Always keep your working area dry.

Electrical installation must observe all state and

local codes. This unit requires connection to a

grounded (three-prong), polarized receptacle

that has been placed by a qualified electrician.

The unit requires a grounded and polarized 115 VAC,

60 Hz, 15A power supply (normal household current). An

individual, properly grounded branch circuit or circuit

breaker is recommended. A GFCI (ground fault circuit

interrupter) is usually not required for fixed location

appliances and is not recommended for your unit because

it could be prone to nuisance tripping. However, be sure

to consult your local codes.

PREPARE SITE

Your U-Line product has been designed exclusively for a

built-in installation. When built-in, your unit does not

require additional air space for top, sides, or rear.

However, the front grille must NOT be obstructed.

The product is designed and manufactured for seamless

integration in the specified cutout opening shown, which

requires precise measurements. The opening must be

square and plumb front to back. Although not required,

you may choose to increase the overall cutout width for

ease of installation.

The Modular 3000 Series units are engineered with a

variety of adjustment features to help ensure a seamless

installation. Adjustable doors, leveling legs and grille will

assist in fine tuning the installation.

CUTOUT DIMENSIONS

Metric measurements rounded and optimized.

All 3000 Series models fully integrate into overlay/face

frame, inset or European/frameless cabinet styles and

install seamlessly into standard 24" (610 mm) depth

cabinet base.

CAUTION

Unit can NOT be installed behind a closed cabinet

door.

(one at a time) without interference.

Hinge-by-Hinge Installation (Mullion)

When installing two units hinge-by-hinge, 13/16" (22 mm)

is required for integrated models. Additional space may be

needed for any knobs, pulls or handles installed.

Stainless steel models which include the standard stainless

handle will require 4-9/16" (116 mm) to allow both doors

to open to 90° at the same time.

However, to ensure unobstructed door swing (opening

both doors at the same time), 1/4" (6.4 mm) of space

TROUBLESHOOTING GUIDE

DANGER

ELECTROCUTION HAZARD. Never attempt to

repair or perform maintenance on the unit

before disconnecting the main electrical power.

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 operating sounds they

make. NOTE: Your product may not contain all the

components listed.

Troubleshooting - What to check when problems occur:

Problem Possible Cause and Remedy

Digital Display and Light Do Not Work.

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.

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.

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 Testing.”

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.

Troubleshooting - Extended 3

USER GUIDE

u-line.com

SAFETY • INSTALLATION & INTEGRATION • OPERATING INSTRUCTIONS • MAINTENANCE • SERVICE

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.

CAUTION

Precautions must be taken while working with

live electrical equipment. Be sure to follow

proper safety procedures while performing tests

on live systems.

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.

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

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 any condensation that may have appeared

on glass doors and shelves.

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

bath (32°F) resistance should measure 16.1 kilohms.

REED SWITCH

A reed switch is used to monitor door state. 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

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.

All 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.

Thermistor connections must be kept clean. A thermistor

connection that has become corroded can cause

resistance values from the thermistor to change as they

pass through a dirty connection to the board.

It is for that reason that we apply dielectric grease to all of

our thermistor connections. Dielectric grease will help to

keep thermistor connections clean and dry.

Thermistor three (Zone):

Located along the right hand side wall in the bottom/right

compartment. It is used to maintain the operating

temperature within that zone.

Thermistor four (Evaporator):

Located on the evaporator in the bottom/right

compartment. It is used for defrost.

Thermistor five (Ambient):

Located in the base of the unit (secured to the

condenser). It is used to monitor the ambient temperature

within the base compartment. It is used for diagnostics.

THERMISTOR FAILURE

Zone Thermistors

If a zone thermistor(s) in the unit fails the unit will

continue to cool in a backup mode (Self Preservation

Mode) to preserve the integrity of the contents. The unit

will otherwise operate normally.

If you change a thermistor in the unit please re-apply

dielectric grease to the connection. If you encounter a

dirty thermistor connection, you should replace the

thermistor and the thermistor harness.

Thermistor error information can be found in the Control

Operations - Service section.

This unit has five thermistors.

Thermistor one (Zone):

Located along the right hand side wall in the top/left

compartment. It is used to maintain the operating

temperature within that zone.

Thermistor two (Evaporator):

Located on the evaporator in the top/left compartment. It

is used for defrost.

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.

3. Disconnect power to the unit.

4. Remove rear center cover from unit.

5. Disconnect fan electrical connection to the fan which

must be changed.

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

Evaporator Fan Replacement

Should an evaporator fan need to be replaced follow the

steps below.

1. Remove any product from the unit.

through hole as needed to gain clearance to pass fan

plug through.

7. Remove internal bins and bin holders, wine racks or

shelf supports as dictated by unit, on the side that fan

motor needs to be changed in.

8. If the unit has bins or wine racks, remove the rear

mounting screw only from the slide assembly on each

side. This will allow the slide to pivot downward from

the front mounting screw allowing ample room to

remove the fan cover.
