I bought my rainbow se vacum 4 years ago and I was
Hi, there is no reset button on a Rainbow vacuum.
All SE series vacuums have a built in thermal and load fuse on the motor, and if it blew, it has to be replaced, or wired directly, with out it on there.
Motor brushes are usually the source of a non working Rainbow D4 and SE and all model Rainbow vacuums and when they burn out, they usually take the motor armature with them, from excessive heat and flare electrical arking to the armature.
It is probably the thermal and load fuse, that is your problem, if you did not smell any electric burning type of smell, before it quit. It could be the power switch, but not as likely as the fuse.
If you have any more questions let me know. I am a Rainbow seller, and a Rainbow expert also.
Thank you,
Ralph
