DIAGNOSIS AND TROUBLESHOOTING
DIAGNOSTIC TESTS
The Diagnostic Tests will test and verify all of
the inputs to the machine control electronics
board. These tests are an overall check of the
dryer electronics and the related components.
The tests should be run prior to making any of
the troubleshooting tests.
ACTIVATING THE DIAGNOSTIC
TEST MODE
1. Make sure that the dryer is in the “Standby”
mode (plugged in and all of the indicators
are off).
2. Press the following control panel keypad
sequence all within 5 seconds:
More Time — Less Time — More Time —
Less Time.
3. All indicators on the console should now
be illuminated with “
88 ” showing in
the “ Estimated Time Remaining ” display,
if this test mode has been entered suc-
cessfully.
NOTE: If the “Diagnostic Test Mode” entry was
unsuccessful, perform the following actions for
specific indications.
Indication #1
Problem: None of the indicators or dis-
play digits light.
DISPLAY FAULT/ERROR CODES
Corrective Action: Press one of the
Manual Cycles pushbuttons. If the indica-
tors light, change the dryer time by press-
ing the
More Time and Less Time push-
buttons.
If either pushbutton fails to change the
time, the pushbutton is defective, and it is
not possible to enter the diagnostic mode.
Remove the console electronics and hous-
ing (see page 4-4).
Indication #2
Problem: E1 or E2 flashes on the display.
Corrective Action: Refer to “Thermistor
Test” on page 5-5.
Indication #3
Problem: E3 flashes on the display.
Corrective Action: Check that the cor-
rect console electronics and housing, and
the machine control electronics board are
installed. To do this, remove these com-
ponents (see pages 4-2 through 4-5 for
the procedures). Check the part numbers
and compare them to the part numbers
shown in the Tech Sheet that is supplied
with the dryer. Replace the components, if
necessary.
