Eureka The Boss Smart Vac won't start

While vacuuming, motor sounded funny and we smelled like a burnt rubber smell. Roller stopped spinning. Turned it off . Checked it out, changed the belt even though other one was in tact. Turned it back on, motor still sounded funny and no suction, no roller turning. Checked everything again, including carpet switch, turned it back on and nothing.Now it won't start at all. Deader than a door nail. Do you think it's the motor? If it is, then is it worth fixing?

    Unit won't start at all. Dead. As I indicated it did generate a terrible smell, sound of the motor changed. We checked belts, etc., started it back up. It still sounded strange and roller not turning and no suction. Turned off again and it was dead...no sound, just dead.

    If the motor has burned out, I understand it has a horrible smell. This did have a horrible smell and the sound of the motor changed, but it still would power on. Now it no longer powers on at all and is totally dead. The cord appears to be OK. So does repairing/replacing motor make sense considering a new one costs about $125?

Yes its motor problem.First it was very weak and overheating.And now it got overheated and went short.Replacing the motor should help. The Eureka 4870 motor actually is a very high output motor and creates a decent amount of suction power. and yes its advisable to get the motor replaced.Its worth getting it replaced.Its a good unit and has very long life. Thanks. keep updated for any more query.you can rate this solution and show your appreciation.

    Yes the motor is costly.But if you have used the vac properly and carefully then you can go for motor replacement.But if the unit is used too much then going for new unit is advisable.Because cost of new unit is near to $160.And is near to cost of new motor.

    Thanks for the appreciation.

You problem must be with the motor belt, but if you smelt burnt rubber there's another problem which made your motor belt loosen or broken. There must be some short inside the operating components which in turn sparked and then broke the motor belt. This is very common with vacuum cleaner and you'll not be able to find out unless you open it apart.

If you wanna try, you can open the base opening, but I don't recommend doing it "do it yourself" method since that could bring more damage if you have not sufficient knowledge. I would suggest you to call a technician or if possible take it to the servicing center to get it repaired. I am sure that your machine can be repaired if it's power on. But if it's not, then I can't assure you, but you can give a try if it's only with the motor. This could be a burned out motor, from which my advice would be to go shopping and buy a new one if you know how to replace a motor (you'll need a soldering, soldering wire, etc..). But before we go shopping it’s always worth checking to see if the cord has become exposed or broken in some way.

Quite often vacuum cleaner cords are ran over by the machine and become tattered. With a thorough inspection you can look for any exposed wiring, and cover it with electrical tape. The two sets of wires in the cord cannot touch each other and need to have tape wrapped around them separately. If the copper is broken, it can be twisted together with needle-nose pliers, and then taped. Once the cord is inspected and exposed areas have been ruled out, it is always possible that the cord has been pulled away from its connection to the motor. Look for all the screws on the body that hold the plastic case housing the cord. Remove them and check the area where the cord connects to the inside wiring. If disconnected, match the same color wires and twist them together with needle nose pliers and cover the wiring with tape. Reassemble the casing with it screws and plug your vacuum cleaner in. These repairs should have your cleaner powered up and running.

My suggestion to you is to call a technician, unless you are sure what you are doing with it. If you know about wiring, soldering, etc.. no problem go ahead, you'll be able to find out the problem and will be easily able to notice how to fix it.

I could only wish you good luck.


Thanks for using FixYa.

Hello,

wiggle the cord while running the vac. if it cuts off from that, then you most likely have a bad switch or cord. if the motor is bad, you would smell it. it smells awful. If it is the motor, it is still worth fixing it if you still love your eureka the boss smart vac, you can go ahead to replace the motor on the device but if still under warranty, contact the dealer for service or replacement of the motor but if not, go ahead to replace the motor because with the smell you said perceive, the motor is bad, replace the motor on the device.

Take care.

Eureka burning smell


Hi, it's Cindy from Crucial Vacuum.

Since you have replaced your Eureka 4870MZ 9200 Proheat 2x vacuum's belt, the issue may either be caused by your roller or the position of your belt. It sounds like as soon as your vacuum is lowered, the belt is either slipping or wear on the end caps is causing your roller to stop. This will cause the burning smell since your motor is now straining against the abrupt stop. Try taking off your roller and checking the conditions of the end cap or try to reinstall your belt. I have included an instructional video: http://youtu.be/rji0fl9hytY

My Eureka The boss Smartvac Model #4870 roller brush won't turn even on the highest setting and the belt smells hot. we took the belt off. How can you tell if it needs replaced?


Just by what you explained I can tell that it needs to be replaced. The belt doesn't have to be broken to need replacing, if it is stretched and worn then it will slip on the motor shaft and not turn the brush roll and get hot. Here is a link to the belts you need and the manual which has instructions:

I have a eureka the boss smart vac petlover vacuum and I cannot find the book on how to replace the belt. I have opened it up, but there is a silver roller that is confusing me.


Either go directly to the Eureka internet site, or GOOGLE "eureka boss smart pet lover manual". Several options should be displayed to download the needed manual.

Eureka boss power plus


I had this same problem. The brush roll wouldn't spin, smoke came out, and it smelled like burning rubber. I changed the belt thinking that would fix the problem but it didn't, so I took the belt back off and checked the motor shaft in the back and found a whole bunch of hair wrapped around the shaft. Once I cut out the hair with some scissors and replaced the belt, everything worked like normal. I hope this helps.

Eureka 2961 BVZ no suction, burning smell


I have the same vacuum. The burning smell is letting you know that your belt is either broken or about to break. I have had mine for a year and have had to replace the belt 5 times. Now I have to replace the brush roller 'cause it broke under normal use. My next vacuum will be a Dyson Ball.

Smell/suction


The brushroll may spin when looking at it but stops when pressure of the floor is applied. The belts stretch, so they look fine but are not. The smell - if it's a rubber smell - would also be the belt. Some, or most, brushrolls can get hair in the ends that could also cause a smell and belt problem.
