Dryer Control Troubleshooting
IMPORTANT: Refer to wiring diagram for aid in
testing dryer components.
7. Dryer Error Code Listing
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect all electric power to the machine and accessories before servicing.
• Close gas shut-off valve to gas dryer before servicing.
• Never start machine with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
re
connected to ensure that the machine is properly grounded.
• Washer motor not grounded! Disconnect electric power before servicing motor.

WARNING
Display Description Cause/Corrective Action
Locked rotor error: The motor is not sensed as
rotating when it should be.
Terminate cycle and check that nothing is obstructing
motor rotation. Check wire harness connection
between motor, user control and output board, or try
replacing the user control or the output board. Clear
error with a key press.
Open thermistor error: The thermistor circuit
is sensed as being physically open.
Remove any lint build up around thermistor. Check
wire harness connection between thermistor and
harness. If problem persists replace thermistor, harness
or output board. Thermistor must no longer be seen as
open to clear.
Shorted thermistor error: The thermistor
circuit is sensed as being shorted.
Remove any lint build up around thermistor. Check
wire harness connection between thermistor and
harness. If problem persists replace thermistor, harness
or output board. Thermistor must no longer be seen as
shorted to clear.
Motor output shorted error: Hardware error. Terminate cycle. Replace output board. Power down
machine to clear.
Door input acquisition error: Hardware error. Terminate cycle. Replace output board. Power down
machine to clear.
Centrifugal switch input acquisition error:
Hardware error.
Terminate cycle. Replace output board. Power down
machine to clear.
High limit thermostat input acquisition error:
Hardware error.
Advance cycle to cool down. Replace output board.
Power down machine to clear.
Output board communication error:
Communication failure.
Power down machine to clear, power up and try again.
If error persists, check harness connection between
user control and output board, or try replacing the user
control or the output board.
Output board not ready error: Hardware
failure.
Terminate cycle. Replace output board. Power down
machine to clear.
