AUTOMATIC DEFROST UPRIGHT
FREEZER - R600a
The defrost period will vary dependent on the heater on time,
with a maximum of 60 minutes. There is a 7 minute idle (drip
time) time after the heater turns o before the evaporator fan
and compressor will turn on. During the defrosting period a
temperature sensor monitors the evaporator temperature and the
main control board turns the defrost heater o after the frost on
the evaporator has melted.
IMPORTANT: PLEASE RETURN THIS SHEET TO
ITS ORIGINAL LOCATION.

SERVICE MODE DIAGNOSTIC TESTS
Allows technicians to step through available tests to diagnose individual
electrical circuits.
NOTE: There is a magnetic switch located in the bottom front of the cabinet
(beside the green power on indicator light) and a permanent magnet is located
in a holder in the bottom of the door that work together to sense when the door
is opened and closed.
To Enter
Service Mode:
To manually exit
service mode:
To activate
manual defrost:
• Open the door.
• Using a permanent magnet, activate the magnetic
switch 4 times within 2 seconds, holding the forth
activation against the magnetic switch until a long beep
is heard and the interior AC LED Light bulb turns on.
• Move the magnet away from the magnetic switch.
The internal light will turn o indicating the unit is in
service mode.
NOTE: When service mode is entered, the green
power on indicator light will remain on.
• Using the permanent magnet, activate the magnetic
switch 2 times to terminate the current test and
activate the next test. Two beeps will sound conrming
the service mode has advanced to the next test.
• Test 1: Compressor and condenser fan:
The compressor and condenser fan turns ON as
soon as service mode is activated.
• Test 2: Defrost heater
NOTE: The defrost heater has a thermal fuse on
each side of the heater element. During the defrost
heater test the main board monitors the evaporator temperature and will automatically turn o
the defrost heater, if the evaporator temperature
exceeds a specied value to ensure the thermal
fuses are not permanently open circuited as they
are designed to operate.
• Test 3: AC LED bulb
CAUTION: DO NOT REPLACE THE AC LED BULB
WITH ANY BULB GREATER THAN 5 WATTS.
• Test 4: Evaporator Fan
• Using a permanent magnet, activate the magnetic
switch 4 times in 2 seconds, holding the forth activa-
tion against the magnetic switch until a long beep is
heard and the interior AC LED Light bulb turns on. The
unit will restart in normal operating mode.
• Unplug the unit from power and plug it back in to
power. The unit will restart in normal operating mode.
• The unit will automatically exit service mode if no
magnetic switch activation is detected after 10 minutes. The unit will restart in normal operating mode.
• Using a permanent magnet, activate the magnetic switch
5 times in 2 seconds, holding the fth activation against
the magnetic switch until ve short beeps are heard.
• The unit can enter in manual defrost only during
normal operating mode.
• The unit will not enter in manual defrost if already
in defrost mode.
• The unit will not enter manual defrost if the tem-
perature control knob is in the OFF position.
• The defrost heater has a thermal fuse on each side of
the heater element. During manual defrost, the main
board monitors the evaporator temperature and will
automatically turn o the defrost heater if the evaporator temperature exceeds a specied value to ensure
the thermal fuses are not permanently open circuited
as they are designed to operate.
