I have the model 3750-T, and the other day I had a power surge, while vaccuming, which caused the motor in the "brush" section (the bit that makes the most noise) to stop working completely. Basic suction works, but this thing doesn't do much anymore....it's essentially an oversized hand vac. Wondering if anyone has had any problems like this before, i'm hoping it's a blown fuse and not a totally blown motor. I'll see if i can pull it apart later today and find out for sure.

Re: Blown motor, or just a fuse?
Suggest you double check that this machine really does have a separate motor to drive the brush roller - most just have a single motor that drives the vacuum impeller directly, and the roller through a belt.
If yours is the same, then the most likely problem is a worn-out belt. Hope so, as this makes for a cheap and easy repair.

1) test the for loose connection in the power cord terminal tight or resolder 2) test the thermical fuse, for loose or defective 3) test for motor brush, repair, clean, and lubricate. 4) test for bel, loose, worn, or breake and replace. God bless you
most upright vaccums have a reset button at lower rear area of the vaccum. operates similar to gfi plug reset, push button back in usually with small screwdriver. is your debris bag to full? power brush jammed with debris? hose plugged? this will cause motor to over heat and in turn kick out reset button. always unplug power cord before putting fingers in areas where moving parts are!!
Is this the Lightning model? How old is it? You may have to just replace the belt.
Also, the front brush motor will not engage until the power is turned on and the handle is in the down position. In the upright position the brush motor wont engage. Typical faults will be the belt is broken and needs replacing or the fornt brush motor needs replacing.
There are threee filters inside this unit. Be sure all three are clean. You can't clean the Hepa filter. You can only replace it. You may even try pluging it in and running it (not while vacuuming the carpet) without the filters to see if it is clogged up anywhere. It's not uncommon to **** up an object that doesn't fit though the vaccum hose very well and for that item to cause hair etc to catch on it and plug that hose. Before you know it you have a big plug in that hose. The hose detaches easily. Look through it.
Hi there it's SmartAlec from NelsonVacuums.com.au here. It will either be the fuse or the motor itself. If you disconnect the wires from the fuse and join them together and it works you will know it is the fuse that needs replacing. If it does not work then it is the motor itself. Depending how competant you are you can dismantle the motor itself and check the brushes. Other than that it needs a complete new motor. If you are in australia you can contact me on 0269215200 and i can supply anything you need as i am a rainbow agent. Hope this helps - happy vacuuming :)
