Field Service Mode
To enter the Field Service Mode, disconnect then
reconnect the electrical power at the wall outlet.
Within 30 seconds, simultaneously press and hold
the Cottons and Start/Pause buttons for 3 sec-
onds. The unit will start and run, but continue to
hold the buttons until the diagnostics mode is
entered. As soon as the test cycle is entered, the
Dual Seven Segment Display (DSSD) displays, in
sequence, the letters Fd (Field Service Diagnos-
tics), EL or GA (for electric or gas dryer type), and
the EEPROM version number. Wait for the DSSD
to turn OFF before proceeding with testing.
To index to the next test position, press the Mixed
Loads button. To return to the previous test
position, press the Easy Care/Perm Press button.
The following tables give the functions for the
subsequent positions.
