American Dryer eXtremeAir® GXT9 and EXT7 Smart Sensor
Complete 100-240 Volt SM239
Replacement sensor circuit board for all eXtremeAir®
GXT9 and EXT7 American Dryer hand dryers.
The SM239 will
upgrade the EXT2 and EXT4 hand dryers to an EXT7 hand dryer. We do not advise doing this
in the field because the upgrade requires the factory to apply a new electrical
label on the product. This upgrade is only recommended for customers having
issues with the sound level of the EXT2 and EXT4. In such cases, it is best to send the
dryer in to us for an upgrade (conversion fees may apply). For more information
on upgrading the EXT2 or EXT4 please call us.
