World Dryer Part 91-804 IR Sensor Kit [fits Electric-Aire LE1 & LE4 hand dryers]

Sensor / Optic Board for the Electric-Aire LE1-974 or the LE4-974 hand dryers

NOTE: If the sensor has gone bad on your LE1-974 or LE4-974 hand dryer, you may need BOTH the Sensor / Optic Board sold here as well as the PCB Control. If you KNOW that only one or the other has gone bad than you can get away with purchasing just that one, but otherwise you need to purchase them both.

Also, the Electric-Aire is still sold at a pretty low price, so you may also want to consider purchasing a new unit.

For the PCB (control board), see WDP-91-805 for the 110-120V version.
For the 208-240V version, see the WDP-91-806.
