Fellowes 420HS paper shredder "cabinet door ajar" red light is on and will not run forward (cabinet door is closed). I jumpered the wires to the door switch but that made no difference. It does run in reverse. Thank you. Mac

    I already have an operating manual. I need a technical manual with the schematic. The "door ajar" red light and the "forward run" green light are both on at the same time.

    The shredder has a PSC motor. I confirmed that the problem is not with the motor because it runs forward if I interchange the motor coil which is connected to the start capacitor. This, of course, bypasses all of the automatic and safety features.

    Thank you,

My fellowes ps-70 shredder has a light on and it's not working

If the shredder is the kind that turns on when you insert paper, it may have an optical sensor that is dirty or blocked. Try blowing off the sensor with some canned air. The sensor is usually located in the center of the paper path slot. Also check that the bin is completely closed. Sometimes a tab on the door is bent or broken so that the shredder thinks the door is open. The tab activates a switch which tells the shredder that the door is safely closed. Fellowes has a lot of good tips on their website.

Shredder keeps stopping and the bag is not full

there are three switches on most shredders that can cause them to stop.
1) a jam
2) door ajar
3) bag full
If you can rule out a jam, and the door ajar light goes on when the door is open and off when its closed, and the shredder has not been undergoing very heavy use (they will overheat and shut off, then be fine in 15 min or so)
then its a safe bet to say that it has to do with the switch that tells the shredder that the bag is full (when you take out the bag you can see a metal flap hanging down at the back of the top opening)
the way that the shreddings fall can often trip the swtich that tells the shredder that the bag is full, shake the bag a bit so the paper resettles that often fixes it.

Paper gets jammed. Even shredding just one sheeet of paper. Clicking noise is heard before the red light comes on.

The problem was solved by putting some oil on the top of the shredder and running the motor forward and in reverse to coat the teeth. Thank you.

Basket ajar light stays on even when the door is closed. How do we get the light to go out?

The door sensor could be bent or broken. There is also a thin piece on the door that pushes the sensor switch. Check to see if it is broken. Try pushing a thin object into the sensor **** opening and listen for a click.

Unjamed, but jammed light remains on and won't shred

Most likely the PC board has gone bad. It will cost over 100.00 from fellowes.

Red light on will not run in forward

Check to make sure the shredder is sitting on the paper bin properly. Most shredders have a sensor switch that disables the unit if it's not properly seated on the paper bin.
