SERVICE DATA SHEET
A14365701
AUTOMATIC DEFROST UPRIGHT
FREEZER - R600a
DEFROST CONTROL
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 off 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 off after the frost on the evaporator has melted.
IMPORTANT: PLEASE RETURN THIS SHEET TO ITS ORIGINAL LOCATION.
Specifications subject to change without notice. For complete performance data by model, refer to service manual. Options shown are not necessarily part of the model.
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 |
• Open the door. |
Service Mode: |
• 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 off 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 confirming |
|
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 evapora- |
|
tor temperature and will automatically turn off |
|
the defrost heater, if the evaporator temperature |
|
exceeds a specified 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 |
To manually exit |
• Using a permanent magnet, activate the magnetic |
service mode: |
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 min- |
|
utes. The unit will restart in normal operating mode. |
To activate |
• Using a permanent magnet, activate the magnetic switch |
manual defrost: |
5 times in 2 seconds, holding the fifth activation against |
|
the magnetic switch until five 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 off the defrost heater if the evapo- |
|
rator temperature exceeds a specified value to ensure |
|
the thermal fuses are not permanently open circuited |
|
as they are designed to operate. |
