(Motor error)
Connector dis-
connection for the
motor Check if the lead wire connectors between the motor and the
power circuit board (JT-33P) are disconnected.
Motor brush at the
end of its life Replace the blower (assembly).
Motor lock Check if the motor vanes are locked.
Blown thermal
fuse of the motor Measure the resistance between the both ends of the motor lead.
If it is
∞ Ω , replace the blower (assembly).
Malfunction of
the control circuit
board (JT-33M) If no error is found after checking the above, replace the control
circuit board (JT-33M).
Malfunction of
the power circuit
board (JT-33P) If the error persists after replacing the control circuit board (JT-
33M), replace the power circuit board (JT-33P).

Unusually worn-
out motor brush Replace the blower (assembly).
Motor brush at the
end of its life Replace the blower (assembly).
Malfunction of
the control circuit
board (JT-33M) If the error persists after performing the above, replace the control
circuit board (JT-33M).
Malfunction of
the power circuit
board (JT-33P) If the error persists after replacing the control circuit board (JT-
33M), replace the power circuit board (JT-33P).

(Temperature detection er-
ror (Power circuit board))
An abnormal
temperature has
been detected. If the temperature on the power circuit board (JT-33P) rises due to
the overuse, the hand dryer stops the operation.
Leave it until the temperature falls, and then check if the error oc-
curs again.
Malfunction of
the power circuit
board (JT-33P) If the error persists after performing the above, replace the power
circuit board (JT-33P).
