The following table relates to troubleshooting the electronic control and associated components.
P P r r o o b b l l e e m m
Compressor does not
run.
User interface display
shows "CE". This indi-
cates a communication
error between the user
interface and electronic
module.
Cabinet temperature
not within limits.
Freezer does not go
into fast freeze mode
when the fast freeze
key is pushed.
Alarm system does not
sound when freezer
temperature is above
23°F.

1. Do any of the LED's on the control
illuminate?
2. Is the temperature control set to off?
3. Remove interface from the door and
disconnect the wire harness from the
interface. Measure the voltage
between the brown and orange wires
in the plug. Is the reading greater
than 4.3VDC?
4. Is the voltage greater than 5.7VDC.
5. Disconnect the user interface cable
from the electronic module. Measure the
voltage between the red wire and the
black wire in the harness plug that is
connected to the electronic module. Is
the voltage 0.3VDC greater than the volt-
age reading in step 3.
1. Check the connectors in the wiring
between the user interface and
electronic module. Is there a wiring
problem?
2. Replace the user interface. Does this
correct the problem?
3. Replace electronic module. Does this
correct the problem?
1. Initiate service mode and check
thermistor. What appears in the
display?
1. Check wiring and the connections
between the user interface and
electronic module. Is the wiring
defective?
1. Does either the alarm sound or the
indicator light illuminate?
Yes. Go to step 2.
No. Check power to freezer and make sure
unit is plugged in.
Yes. Set temperature control lower.
No. Go to step 3.
Yes. Go to step 4
No. Go to step 5.
Yes. Replace defective electronic module.
No. Replace user interface. If problem is
not corrected replace electronic module.
Yes. open wire or connection. Check all
connections and wiring. If defects cannot
be found, replace door.
No. Replace defective electronic module.
Yes. Correct wiring problem.
No. Go to step 2.
Yes. Problem solved.
No. Go to step 3.
Yes. Problem solved.
No. Recheck wiring. If problem still exists,
replace the door.
If "C" or "O" appear in the display, replace
thermistor.
If "-" appears in the display, replace
electronic module.
Yes. Correct wiring problem.
No. Replace interface board. If problem is
not corrected, replace electronic module.
Yes. If the indicator light illuminates, but
the alarm does not sound, replace electron-
ic module. If alarm sounds but light does
not illuminate, replace the user interface. If
problem is not corrected, replace electronic
module.
No. Replace electronic module.
