I need to replace the fuse in my wilson jones 1252 shredder. Whats the number on the fuse?

Just take it apart and unplug the switch that is keeping it on. take pictures when you pull apart the cases. sometimes some of the screws are under labels. Should be no more than five screws. Paper has an oily presence and causes these type of failures.

If you wish to get more; check the site linked here. It has set-up code list & set-up procedure to many popular brand remote controls. Pull up older posts.

Oddly, my Wilson Jones 130 auto just did exactly the same thing. I'm the only one that uses it (that I know of) and one day it worked, the next it didn't. There is no paper stuck in it. There are no power lights, nothing works. Does anyone know the location of a reset button or something?

Wow, a name from the past.... with any shredder the easiest way to "oil it" is just to put a bead of oil in an "S" pattern down a sheet of paper to be shredded and then shred the sheet of paper.
If you shred a lot you should do this more frequently...if its only occassional shredding OR if its a strip cut shredder then you don't have to do this as often.

Spray some contact cleaner into the buttons and this may free them up. try this

Clearing the "Service Due" prompt:
1. Lift safety flap (plastic cover over paper entrance).
2. Depress Reverse and Stop button simultaneously 2-4 seconds.
3. LCD display reads, "Service Info 1"
4. Press Stop button once to obtain "Service Info 2"
5. Depress Forward and Reverse buttons simult. 2-4 seconds.
6. "Service Due" prompt will be cleared and service hours zero.
7. Snap safety flap down to close.
