In this article we will go through the function of the brush roll indicator light, and how to deal with it when it malfunctions.


What is the indicator light’s function?

Shark vacuums come with a brush roll designed to agitate carpets deeper to get rid of ground in dirt. The roll is powered by a separate belt that activates when the handle is pulled down and the roll is released. In order to help prevent damage to the brush roll Shark has included the indicator light. When the light is illuminated green, the brush roll is functioning properly. Red indicates that the brush roll is blocked.

Alternatively, when cleaning the vacuum, if there is no brush roll obstruction the red light may indicate that the vacuum is overheated.

What causes Shark vacuum brush roll indicator light is not on ?

We are going to start with the simplest solution for “Shark vacuum brush roll indicator light not on.” The Shark vacuums power switch has two modes; mode one is indicated by “I” and it activates just the suction of the machine. Mode two is the brush roll mode and is activated when the switch is flipped to the “II” position. If the switch is in the wrong position, the light will not activate and neither will the brush roll.

If you have the switch in the correct position, next make sure the nozzle is fully attached. If not attached, power will not be able to reach the roller brush. No power, means no light. With the vac fully upright, push firmly down toward the head. Firm pressure should cause the nozzle to fully engage.

The third stop on your “Shark vacuum brush roll indicator light not on” troubleshooting journey is to check the brush roll for blockage. While the light should turn red, the blockage can prevent the system from activating. Clearing the blockage may help restore function. Ensure the vacuum is unplugged then lay it down to access the roll. Newer models have an easily removed brush roll that is covered by the “roller garage cover.” Remove hair or threads that are causing the brush roll to stick.

Replace the roll, plug in and start the vacuum. With no obstructions on the roll, the vacuum should function normally. You can avoid this kind of malfunction by cleaning the brush regularly, and not allowing hair and threads to build up around the roll.

The fourth most common cause of issues is the vacuum overheating. You can know if the vacuum is overheating if you have been cleaning for a while and the vac stops working properly but there are no obstructions. When the Shark gets too hot, remove the dust bin and clean the filter making sure there is no debris blocking and tubing of the vacuum. Allow the vacuum to cool for at least 45 minutes. Plug in and start over again.

The last problem that could be stopping you from creating a beautifully clean home, and causing, “Shark vacuum brush roll indicator light not on” is damage to the belt that drives the brush roll. This belt is supposed to be a lifetime belt, so if the problem is indeed the belt, you will need to contact Shark for service and repair.
