COMPONENT TEST
D SENSOR
1. Make sure the Easy Wave Open (motion sensor function) is activated. When activated, the blue LED
indicator light unit turns ON when drawer door is closed.
2. Check sensor lens for foreign material.
3. Check if the control panel door is defective and sagging down lower than normal when open, which
could block the view of the sensor. Close the control panel door to ensure the control panel door is
not blocking the sensor and test again.
4. Check the connector and harness to the sensor to ensure they are secured properly and not broken.
5. Check for electrical parameters in the table below. If those conditions are met, then the display unit
is working properly.
(NOTE: If the voltage is uncertain, change display unit)
6. Check for electrical parameters in the table below. If those conditions are met, then the sensor and
display unit are working properly
