Basically take the separate the top from the bottom and you can see how to remove and replace them. Usually 4 screws under the top cover. Carefully separate the top and be gentle with the short cable connected to the main board. You can order the sensors from Fellowes.

At first the shredder would only run for 3-4 seconds, then quit. Turning the rocker switch off, then back on, would cause the shredder to run another 3-4 seconds, OR pulling the collection bin out, then...

could be the sensor needs cleaning or is now defective. Use a q-tip and insert it where the paper goes. Look for a small button which senses the paper and triggers the stredder motor.

look for two LED lights where paper falls into bin and wipe them off, but the sensors could be faulty as well. I have seen both.

The Basket full light will not go out. I have cleaned the paper pathy and the light goes on after about 10 shreaded papers

Did you clean up underneith the cutter asm. Unplug the un it and remove the basket then turn it upside down and clean the shreds out then clean the led sensors with a dry cloth.

Shredder won't turn off

The sensors probably need replacing. Most larger Fellowes shredders come with a three year warranty. It will not hurt to use it the way you are using it.

Paper shredder

Shredders have a light emitter and detector inside the slot where you put the paper. When the paper is put in, the emitted light is reflected off the paper, detected, and then turns on the shredder by sending a signal to the control board. The emitter/detector often has a plastic cover which over time collects paper dust. The paper dust can reflect the emitted light back onto the detector, causing the shredder to remain on. You may need to remove the top of the shredder and remove the shredding mechanism to get to the light sensor. It's also possible that the components on the control board have changed value, causing the detector sensitivity to increase. This may result in the unit turning itself on in daytime and off at night.

Short run time and redlight, stops running Fellowes DM15C

There are two sensors (look like little light bulbs) on the top part of the shredder at either end of the blades. If you pull out the drawer and turn the shredder upside down you will see them. They get dirty telling the machine that it is full and needs to be emptied. Clean the sensors off with an alcohol wipe. If cleaning them does not work you need to replace the sensors.

DM15C stops after 4 seconds, open bin light comes on

I lived with the problem for 6+ Months -- drove me NUTS -- Today, I called Fellows -- Spoke to "JoAnn"... She said this works 80% of the time...
Pull out the bin -- put your foot inside to hold the shredder down -- pull up on the top of the shredder -- you WILL hear a POP as the plastic top disengages from the bottom but TRUST ME THIS IS OK! -- take off this top section (which houses the blades) -- flip it over -- you will see 6 screws total but it is the sets of 2 screws close together to focus on -- right next to the screws you will see a tiny glass sensor -- use a q-tip and alcohol to give them a wipe -- press the top back on -- bin back in -- you are DONE -- This took me less than 1 minute and it works as it did the day I got it! Go shred something!  :)

Shredder won't shut off after paper goes thru

Note that the sensors that tells the shredder to stop are underneath the unit.

Pull out the tray, put the unit on the side and you'll see two places where there are two flat-head phillips screws holding the optical sensors in place (no need to unscrew them). Just wipe the visible part of those two sensors with a rag.

The sensors that are readily visible on top of the unit tells the shredder when to start.
