TROUBLESHOOTING TIPS
These troubleshooting tips are for the newer XLERATOR/XLERATOReco dryers (#40103 control) and ThinAir dryers (#40106
control) with the LED light conveniently located within the sensor at the bottom of the dryer. For older models, with the LED light
in the Control (#40102), or an older open green circuit Control with no LED light (#40100 or 40101) please skip to page 2.
CODE CHART FOR EXCEL HAND DRYERS
Codes are displayed by the flashing of the red LED in the sensor adjacent to the air outlet. Normal operation will be indicated
by the red LED being on when not drying and off when motion is detected under the sensor.
MOTOR CODES - First verify that dryer is receiving correct voltage at Terminal Block
1 LONG / 3 SHORT FLASH
Motor Over Current – Verify dryer
is receiving correct voltage per
rating sticker on Blower Housing.
If voltage is correct, reset circuit
breaker in electrical panel box.
If problem not resolved, replace
Control Assembly or Motor.
Dryer will stop.
1 LONG / 4 SHORT FLASH
Motor Under Current – Verify
dryer is receiving correct voltage
per rating sticker on Blower
Housing. Motor Brush could be
