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”
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
Indication 2: E1 or E2 flashes on the display.
Action: Proceed to TEST #3a (Thermistor Test) on page
Indication 3: E3 flashes on the display.
Action: Check to make sure that the correct electronic control board, console electronics, and housing are installed.
