Model #21637045800 Kenmore vacuum, upright

Thank you for your question on the breaking of the replacement belts for the upright vacuum cleaner.

I will give you the instructions from the owner's manual just in case you do not happen to have them.

Please observe the location of the belt tighten pulley.

If you have done the belt replacement correctly then I would suggest making sure the roller brush bearings spin freely.

If the belt is being burnt at the motor pulley shaft it will point to the roller brush bearings as the most likely problem.

I am going to assume that you are using the correct belt as listed in the link below.

Please let me know how it went and if this did not solve the problem we can continue troubleshooting with the new information..

Belt for vacuum .

Thank you for the update Norman. If you are sure that the agitator is rolling freely and the idler pulley is operating the belt correctly as per the picture in the manual, then I think you may have encountered a bad batch of belts if they snap clean as you say. Maybe you will need to get some belts from a different source so you are using belts from a different batch. I will give you a link below for some of these belts. The other option is to purchase some of these belts from a different retail store. If you do that and they work better please let me know so I can inform our parts vendor of the problem. Sam A.

Thank you for your question on the vacuum cleaner. Are you having belt drive problems with your vacuum cleaner? Please give me a little more detail as to the problem you are having. Sam A.

Mr. Norman Graham could you please send your contact information to my e-mail address? I have contacted management and we will need your contact information so our Blue Ribbon group can contact you about your request. Please send it to: sande38@searshc.com. Sam A,

Thank you for your question Thien. I would suggest removing the roller brush from the vacuum and cleaning and or checking if the roller brush bearings are turning freely. The symptoms you are detailing sound like the bearings in the roller brush are seized and not allowing the roller brush to turn and burning up the belts when you turn on the vacuum cleaner. If they are not then you will have to clean the any debris that may have rapped around the roller brush axle. If you decide to replace the roller brush I would do it soon because they are getting hard to come by. I will give you a link for this roller brush below. Sam A.

This message is for Norman Graham. Could you please e-mail me @ sande38@searshc.com, for some information on you vacuum cleaner. Sam A.

C! I am gathering data to see how many belts with the recent threads I have had on this site, and I am also in contact with the vendor to see if they are aware of the problem and have purged any old stock and not shipping out any more bad belts. They are investigating it and will get back to me. Sam A.
