Error
Code
Label
Description Solution
E10
General
EEPROM
Fault
Problem with communication
between EEPROM and the
microprocessor.
Clear code, exit mode and start dryer. If problem persists, replace electronic
control.
E11
Checksum
Error
Problem with communications
or memory did not check,
one has become corrupted.
Clear code, exit mode and start dryer. If problem persists, replace electronic
control.
E12
Non fatal
R/W error
Problem reading or writing to
the memory or input/output.
Clear code, exit mode and start dryer. If problem persists, replace electronic
control.
E24
Control NTC
Short
Circuit
Control thermistor or its wir-
ing is shorted.
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.
E25
Control NTC
Open
Circuit
Control thermistor or its
wiring is open.
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.
E4A
Program
Time out
Fault
The drying time has
exceeded program time for
that cycle.
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.
E5B
Heater Fault
(no
heating)
Temperature reading of
control thermistor has not
changed in a certain amount
of time.
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.
E68
Key (button)
Struck Fault
One of the keys (buttons) is
stuck closed (active).
Enter function test mode and perform key (button) test to determine which
button is at fault. Carefully free the key (button) and perform the test again.
If button is free but the key struck code still exists, replace electronic control.
E8C
Too many
trips in a
period of
time.
The safety (high limit)
thermostat has tripped too
many times within a certain
period of program time.
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.
EAF
Watch Dog
Reset
Microcontroller has been
reset by internal Watchdog
timer.
Clear code, exit mode and start dryer. If problem persists, replace electronic
control.
