I had a clog in the hose and the motor got hot and turned off but a bad smell came from it. I have cleaned all the filters and the clog and it will not get any suction and over heats within seconds of turning it on again. I have tried to run it with out the canister and filters and it dose the same thing. I was told the motor would not burn out because it had safety measures built in to prevent this. It will power up briefly and shuts off.

Re: Motor gets hot in moments and shuts off
True, the motor has safety measures to stop it from overheating... that's why it shut down. You smelled something, so some kind of damage was done. It's possible that the over temp switch itself got fried. Doesn't sound too good from here.

Same thing happened to me. I checked the owner's manual and it turns out the Eureka Envirovac has a built-in thermal cut-off switch. So anytime the motor gets too hot, it just shuts down. Most of the time this is because it gets plugged or the filter is too dirty. In my case, the dust basket thingy and filter were clogged beyond belief. Probably would help to clean that more regularly in hindsight. Supposedly it will turn back on after the recommended 30 minute wait.
The hot smell could be from the belt or the motor. Turn it on for a moment, turn it off, then flip it on its side and smell the belt that drives the brush. If that is where the smell is coming from, then your belt is burning up. FirsYou'll have to replace it. Be sure there is nothing rubbing on it like debris picked up and stuck. But, even if you do find something stuck in it, you'll still have to replace it since it's burning.
If the smell comes from the motor, do not run it anymore. That will have to be serviced.
Can you get a belt? I can look up a place online for you if you need to order one. Just provide your make and model.
I hope this works. If it does, I'd appreciate your vote. Thanks,
It's possible the thermal reset is defective. It shuts the motor off if it gets hot. Remove the bag door and take the bag off, remove both filters and then turn the vacuum on, just leave it sit there with the motor running. This eliminates the bag or filters causing any airflow resistance. If it still shuts off after a few minutes it's likely the thermal reset is bad. Some vacuums have an external thermal reset button which can be replaced if necessary but on your model it is built into the motor and you must replace the motor. If the motor runs fine put the bag and the filter under the bag back in - (make sure the filter is clean and not restricting airflow) put the bag cover on then turn it on again. If it overheats and shuts off then you may have a clog on there somewhere restricting the airflow. If so check the power nozzle area, the hose coming from the power nozzle, the extension hose and wands for clogs or restrictions.
Make sure all filters are clean, also check the inlet by the brush roll isn't clogged as well as the hose. If this is all ok, then there is a problem with the motor. There is a thermo protector that comes with the motor that could be bad.
Sounds like yu may have a clog, either in the inlet by the brush roll, or the hose. If the hose comes loose, see if there is suction there. If no suction then it is clogged. If suction, then the inlet maybe clogged.
Lose of suction can be from a clog in the hose, dirt inlet by the brush roll, or the motor running slow. A smell, depends which, if a rubber smell, then could be a bad belt and/or brush roll. An electrical smell, could be the motor going bad, if it is the motor, it will need to be replaced.
Check the inlet down by the brush roll to make sure it isn't clogged. If not and the hose isn't clogged, then probably the thermo protector (part #28382093) maybe bad. It is mounted near the motor. Could be motor Part #43576188. But I would suspect a clog in the inlet or hose, or the thermo protector has gone bad.
That dust is from the carbon brushes on the motor. You may need to check them, and also clean out the motor compartment. A slight noise could be a motor bearing starting to go. Does the smell like rubber or electrical. If rubber, then the belt has stretched and needs to replaced. If electrical, then something is causing the motor to run hot, like a clogged filter, or it could be a motor going bad.
