Melted Filament sensor  

Melted Filament sensor

My filament sensor melted into my extruder housing last week. I was unable to get it out in one piece. The extruder housing was a mess and parts of the issue must have gotten into the extruder as the filament had stopped. I have repaired the filament flow and need to work on replacing the extruder housing but I would like to get a new filament sensor. I sent a message to Prusa last week about my problem and as of today I have not heard back from anyone. The upgrade had worked very well up to this point. The machine was in the middle of a 12 hour print when it failed. When I returned I found the print head melted into the print and the smell of burned plastic. I removed the print from the print head and found that the filament had stopped flowing. I finally found the issue but when checking the error messages there were none. I'm guessing I had a power failure while I was away that might of had something to do with the problem. I have read that others have had problems with the filament sensor but have heard nothing as to the resolution. Could someone give me the information needed to have my sensor replaced.
