Vitamix needs motor rebuild - Vitamix Super 5000 Work Top Blender

You can typically find replacement carbon brushes for Vitamix blenders at appliance repair shops, online retailers, or directly from Vitamix. Ensure you get the correct model-specific brushes for the VM0145 blender with a 3Hp motor. Double-check the compatibility before purchasing to ensure a proper fit.

What has worked very well for me in the past in similar situations (not with kitchen appliances but any older item needing a part) is find people selling the item or parts for the item on eBay, and then messaging them asking if they have a source for whatever it is I am looking for.
Almost always this leads to what I need, whether it is for a camera or an old watch or a vintage computer or whatever.
Messaging through eBay is easy, fast, and free.
Simply type Vitamix 4000 in the Search box, and get the listings displayed, and then click on Contact Seller.
eBay will send the message, and notify you when there is a reply.

Can't find a wiring diagram but I do have a 34mb video showing a motor being replaced. If you want a copy email me at [email protected] I haven't searched You Tube, you may find something there.

Contact Vitamix, find a service agent through them and have it looked at. You are only going to be able to get your motor (if you need one) through someone associated with Vitamix anyway.

Get an estimate at a local small appliance repair shop,that's what I did,and saved myself a bundle.

first check the blades on the container thay should turn easy by hand if not thats your problem , you will need blades . blades turn easy ? you will need to replace the motor . the temp /overload has changed and is tripping to easy . this is common with people that use there vitamix for tough chores a lot . a lesser blender would just burn up a motor in a puff of smoke .a vitamix dies this way . in the end its the same you will need a motor
