DIAGNOSTIC TESTS

These tests allow factory or service personnel
to test and verify all inputs to the electronic
control board. It would be a good idea to per-
form a quick, overall checkup of the dryer with
these tests before going to any specific trouble-
shooting tests.
Activating The Diagnostic Test Mode
1. Be sure the dryer is in the Standby Mode
(plugged in and all indicators off).
2. Press the following button sequence within
5 seconds of power up:
+ (more time)
– (less time)
+ (more time)
– (less time)
3. If this test mode has been entered suc-
cessfully, all indicators on the console are
illuminated, with “88” showing in the “Esti-
mated Time Remaining” (2-digit) display.
If the entry into the diagnostic mode was un-
successful, take the following actions for spe-
cific indications:
Indication 1:None of the indicators or display
turns on.
Action: Select any Manual Cycle. If the indi-
cators turn on, then try to change the dryer
time by pressing the + and – buttons. If either
button fails to change the time, something is
faulty with one of those buttons, and it is not
possible to enter the diagnostic mode. Remove
the console electronics and housing. If no in-
dicators come on after pressing the Manual
Cycle buttons, go to TEST #1 (Supply Con-
nections) on page 6-4.
Indication 2: E1 or E2 flashes on the display.
Action: Proceed to TEST #3a (Thermistor
Test) on page 6-8.
Indication 3: E3 flashes on the display.
Action: Check to make sure that the correct
electronic control board, console electronics,
and housing are installed.
