20 Most Recent Windsor SR12 Sensor Bagged Upright Vacuum Questions & Answers

Your Sensor most likely has an internal heat sensor that is shutting off the motor. Some vacuums install an external heat sensor with a reset button that you must push to re-start the vacuum. If your model does not have an external reset button it is most likely a sensor inside the motor. If it is defective the motor must be replaced to solve the problem. But first make sure the overheating is not being caused by a blockage somewhere or the bag is too full. Air must pass completely through a vacuum starting at the floor where it picks up the dirt through all the canisters, filters, bags, etc. and then is exhausted from the vacuum. Any restrictions or blockage can cause the motor to over heat. That Vac Guy

Are you vacuuming up fine particals like pet dander or just large amounts of regular dust? Also when was the last time you replaced your filters?

Just some sugestions.

You will also need to remove the screws on the inside that hold the motor in place because part of the side support for the swivel is under the motor. Remember to disconnect wires coming from the swivel as well before you try to pull it out, so that you do not damage them. Hope this helps.

Take it to an authorized repair person.

You most likely will need to change the Yoke assembly. There is a sensor built in that gets clogged with fine debris over time. This will take care of the problem.

Step 1. Remove the vacuum bag housing so that you are only working with the power nozzle or the bottom portion of your Sebo, this will make it much easier to work with. Turn the vacuum upside down, and remove only the 5 screws that I have circled in red:




Step 2. After removing the screws on the bottom of the vacuum cleaner, separate the top housing from the lower agitator housing, sometimes it may take putting a flat head screw driver in between the white and grey colored housing and prying them apart.

Step 3. You now have full access to the belts on your machine. It's most likely the belt that wraps around the brush gear rather then the belt that's attached to the motor that's gone bad. I have never replaced the motor belt in 8 years of servicing Windsor vacuums.

If you have any further questions on how to replace the belt, please feel free to reply to this repair by leaving your question in the comment section, I'm always more then happy to answer any question you may have.

Thanks again,

The Windsor Sensor vacs all have a removable handle.

The handle is inserted into a "socket" which has contacts to complete the electrical circuit.

The handle is held in place by a gray plastic lever.

If the lever is not pressed down completely, the handle is able to slide within the socket during regular use.

If the handle slides out far enough, the electrical connection within will be disconnected and the vac will have no power.

Simply lift the lever, pull up to remove the handle, and re-insert the handle fully, then press down firmly on the lever to lock the handle securely in place.

This is the first step to solve your problem and hopefully this is all that need to be done.

If this does not work, please repost here and I will help you all I can.

Note: I am a big fan of the Windsor Sensor vacs and find them to be easy to work on and a great vac all around!

Check the line going from the bottom of the vacuum to the bag, it may be clogged. A coat hanger can help you clear any jams, but be careful not to puncture the duct.

What color light are you referring to? If it is one of the green lights that is normal for the up and down adjustments. If it is the red one that is another issue. If it is the red one, what does it do while it is on? Does it flash or is it on solid?

I've worked on these a lot. What I think you're explaining is the bypass flow switch which is a common failure. It's located in the base inside the auction side of motor housing...
