READING ERROR CODES
1. Press and hold the Select and Cancel buttons simultaneously for 6 seconds to reset control. The buzzer will sound 1 time
and "rES" will be shown briefly in the display.
2. Immediately after, rotate cycle selector knob 2 turns counter-clockwise to the third position from the top, and then
press and hold the Select and Cancel buttons simultaneously for 6 seconds. The control will enter Field Test Mode, the
buzzer will sound 3 times, and the digital display will alternate between "Fld" and the firmware revision number (ex. "r03").
3. Rotate the cycle selector knob 2 turns counterclockwise. The error code will appear in the digit display.
Troubleshoot problem by using chart below.
To move on to the next code, press the Options button.
To clear code, press the Select button. Code will be cleared when mode is exited.
To exit this mode, simultaneously press and hold the Select and Cancel buttons for 6 seconds.

NOTE: During normal operation, the display may show:
"ad" - dryer is in an auto dry cycle.
"dn" - cycle is done in auto dry.
"PF" - a power failure to the board has occurred.
"Err" - an error has been detected.
"LOC" - control lock is activated.
"PAU" - cycle has been interrupted.
Dryer Tech Data Sheet
This information is intended for Qualified Technicians Only.
Description
Problem with communication
between EEPROM and the
microprocessor.
Problem with communications or
memory did not check, one has
become corrupted.
Problem reading or writing to the
memory or input/output.
Control thermistor or its wiring is
shorted.
Control thermistor or its wiring is
open.
The drying time has exceeded
program time for that cycle.
Temperature reading of control
thermistor has not changed in a
certain amount of time.
One of the keys (buttons) is stuck
closed (active).
The safety (high limit) thermostat
has tripped too many times within
a certain period of program time.
Microcontroller has been reset by
internal Watchdog timer.
Clear code, exit mode and start dryer. If problem persists, replace electronic
control.
Clear code, exit mode and start dryer. If problem persists, replace electronic
control.
Clear code, exit mode and start dryer. If problem persists, replace electronic
control.
Remove wires from control thermistor. Measure resistance of thermistor. If
reading is not 50 K (± 10%), replace thermistor. If reading is within 50 K (±
10%), check wiring between thermistor and electronic control. If good,
replace electronic control.

reading is not 50 K (± 10%), replace thermistor. If reading is within 50 K (±
10%), check wiring between thermistor and electronic control. If good,
replace electronic control.
Press Pause Cancel and SELECT buttons for 6 seconds to exit test modes.
Position cycle selector to NORMAL, temperature selector to HIGH HEAT
and touch START. Check for anything that would extend dry times such as:
no heat, restricted vent, blower fan blade broken or loose, dryer installed in
closet with solid door, or bad connection in moisture sensor bar circuit or
dirty bars. If dryer operates normally but code returns, replace electronic
control.
Position cycle selector to NORMAL, temperature selector to HIGH HEAT
and touch START. Measure voltage across terminals on relay RL2 (heater
relay) on electronic control. If meter reads 240V on electric models and
120V on gas models, replace electronic control. If meter reads zero, remove
power from dryer. Disconnect wire going to NO terminal on the relay RL2.
Reconnect power and measure voltage drop between terminal COM on
relay RL2 and neutral. If meter reads zero, wire between incoming line and
relay RL2 is open. If meter reads 120V, check the rest of the heater circuit.
Enter function test mode and perform key (button) test to determine which
button is at fault. Carefully free the and perform the test again. If button is
free but the key struck code still exists, replace electronic control.
Check for blocked lint filter, blocked exhaust, air leaks around air duct,
broken blower fan blades, worn or loose drum seals, dryer installed in closet
with solid doors or door seal not correctly seated.
Clear code, exit mode and start dryer. If problem persists, replace electronic
control.
