Works in reverse but motor stops running almost immediately when turn to shred. have used only about 1 dz times although have had a year. model as662c

Sounds like its jammed? Have a really close look for staples, paperclips etc stuck in the drive gears or blades

If the motor will not run, then probably there's paper clogged in the shredder. Turn over the shredder, after unplugging the power cord, and remove the papers.

If the motor will run but not shredding any paper, then the drive gear has broken teeth. This is not usually worth fixing.
Hope this helps.

On some shredders when both the forward and reverse LEDs are on it can indicate either a jam or a full receiver bag/ container (the area that the shredded paper is fed into).
Try the following steps:

1. ) unplug the power
2. ) open up the shredder (see 1 on diagram)
3. ) empty out all the shredded paper (see 2 on diagram)
4. ) check that the shredding jaws (both the entrance and exit) are clear of any shredded material (see 3 on diagram)
5. ) put everything back together
6. ) plug power cord back in
7. ) force the shredder into reverse (see 4 on diagram)

Hopefully you should hear your shredder motor running. If it is switch it to automatic and try shredding again

I got mine to work by running it on reverse for a moment then sliding it to auto. It stopped. Then I did it again. This time auto ran just for a second then stopped. I did it a third time but I had a sheet of paper ready in the feeder. Ran on reverse. Slid it to auto and it took the paper and shred it. I did it a fourth time. Reverse slide auto and feed shred the paper. Fifth time Auto shred the paper without reverse. :)

Have you regularly oiled the machine.???
If you dont the shedded paper pieces and paper dust generated in the shredding process will start to clog-up the cutting teeth( oiling helps clean this out ! ) ...if you dont do this then the cutting machanism gets harder and harder for the motor to turn, the number of sheets that can be shredded goes down..the motor overheats and the thermal protection kicks in stopping you from using the machine until the motor cools down. In extreme cases if the machine is consistently run without being oiled and the machine is constantly being jammed you can blow the PCB inside the machine. When this happens obviosly the only remedy is to replace the PCB.

You say its not working??? Does it even run in reverse??? Did you have it jammed up???
A little unusual for one just to stop working for no reason.
If it was jammed up you may have "pooched" the pcb inside. Contact Royal at 1-800-524-0799 for parts assistance.

Try running the machine in reverse and putting some shredder oil onto the cutting blades to loosen things up. Then try running the machine in the forward direction but hold the paper in the eyes but dont let it go into the shredding blades...see if it runs forward.!
If it will do this then slowly try paper 1 sheet at a time..but put some shredder oil onto the sheets of paper you are shredding.
If the overload light still comes on without even letting you shred 1 sheet of paper then you likely have another problem...maybe the motor or pcb..you can contact Royal at 1-800-524-0799 for parts assistance.

Two possible problems;

1. Teeth underneath lid are jammed; sometimes (especially after a long session) although the papers go through, debris builds up and can get caught in the teeth; to clear unplug and with tweezers or a tina flathead screwdriver, pull out shreds of paper still caught
2. Motor is overheated; once cool, try it again (move switch to reverse to see if motor is still working). If motor is working, see Step 1 for a jam; some jams can be cleared by running it in reverse. Royal doesn't recommend "long" shredding sessions. My unit recommends sessions of 20 pages or less. If you try to overwork the shredder, it will overheat and in some cases, fry the motor.

I hope this helps answer your problem. Best of luck!

I had similar problem. I took unit apart and checked the motor by hotwiring it after checking voltage coming off the circuit board connections that the motor is connected to. Motor did not run until I tapped it a couple times with a hammer. Seems ok now.
