That transducer doesn't look common, but try Googling every number on it. It may still be made by the OEM. Otherwise, we will need to repair it, or adapt some other photointerrupter. I would likely try the repair.
We need to figure out which side is broken, the LED or the phototransistor. The LED may not be visible, because it may be infrared. To verify an IRLED is working, look at it through a digital camera. To see what I mean, look at a TV remote control IRLED through a camera while pushing some buttons.
Assuming he IRLED is fine, next test the phototransistor. If a bright flashlight shown on the window will not get it to conduct, then the detector is shot.
Once the broken half is known, we can plan to rebuild the assembly. I would likely, carefully drill out the back side of the offending piece, intending to insert a T1 size case LED or phototransistor from the appropriate side. If your phototransistor is dead, we may need to add a buffer transistor outside (depending on the robustness of the phototransistor we find.)
Before you drill anything, tell us which side of the sensor is broken.
