Service Test Mode
There are several test modes available through the diagnostic system. Use of these test
modes can greatly decrease the time needed for troubleshooting. It is to the service
technician’s advantage to be able to perform many tests in a very short period of time.
Within the Service Test Mode the controls have alternate functions. The FREEZER up
and down buttons (arrows) will move to the next or the previous service test. If you are at
Service Test 4 and press the FREEZER up arrow you will move to Service Test 5.
The REFRIGERATOR up and down arrows will move you through the service tests ten
steps at a time. If you are at Service Test 4 and press the REFRIGERATOR up arrow you
will move to Service Test 14.
The POWER INTERRUPT button will activate the selected Service Test. At every test,
after selecting the test number with the up and down arrows, you must activate the test
using the POWER INTERRUPT button. In many cases the display will change and
provide you with additional information for that particular test. To end a test and return to
the test selection menu, tap the POWER INTERRUPT button again.
To enter the Service Test Mode, the door switches must be held in the door closed
position. It would be easiest to tape the switch in the closed position.
Tap the POWER INTERUPT icon three times in
succession. The system will switch to the service mode
and show the current mode as NORMAL or
no in the
fresh food temperature display.
If the system shows a different indication this indicates that the unit was not in the normal
operating mode.
Pressing The FREEZER up arrow will change the
display to
Sh . This is the Sh owroom mode. If the Power
Interrupt button is tapped at this point, the system will
be in the showroom mode. While in the showroom
mode, the lights and display operate but the cooling
system does not energize.
Pressing the FREEZER up arrow again will change the display to SE. This is the entrance
to the
SE rvice Tests. Tapping the Power Interrupt button will place the unit into service
mode and the display will change to 00 00 with the word service illuminated in the
display.
