Vita-Mix 15955 Potentiometer

My Vitamix 5000 developed some irregular speed at the low speed 5 years ago. We thought about getting a new one but we got by with it because the issue was present at very low speed. Now, after 25 years, The 500 still works well. So, I decided to think of repairing it. After seeing a couple of YouTube clips to make sure I have all needed tools and understand its simple procedure, I purchased this product and it arrived in the next morning.It took me less than one hour to complete the replacement. The time could have been shorter if I did not misplace a set screw for the driver socket. It is easier to remove the driver socket so that I don't need to touch the motor assembly. When loosening the set screw, just turn until the drive socket can be lifted. I turned too much and the set screw dropped in and I only discovered that after putting the top cover back.The replacement (white) is not identical to the original potentiometer (black) as some reviewers pointed out. Just to make sure to insert the replacement with its latch into the slot. In my case, the wires come out horizontally while they came out toward the bottom. Don't be worry about this. The replacement nut for securing the potentiometer is a little bit large (14mm) than the original one (13mm). I need to wrap the rod of the replacement with scotch tap so that the knob can snug back.

WORKED PERFECTLY! But, look in Youtube for a video on how to do it.

This worked great for my Vitamix 5000 model!

Good speed controller. Repaired my Vitamix 5200. This potentiometer looks different but fit perfectly. Its actually an improvement on the old one in that it has a slower speed increase at the bottom of the control range.

We have a 2014 Vitamix 5200 where the speed control potentiometer would stutter/hesitate when adjusted.This replacement works good but the wires are a smaller gauge (16 maybe ) and uses a 14mm fastener nut. So not a OEM swap. But works.My c

This worked perfectly to fix my vitamix which had previously jumped around in terms of blade speed.

I know how to change the potentiometer on my Vitamix vm0103, series 5000 mixer. But I watched a youtube anyway, just to be sure. This is the third one over about the span of 20 years. These last two are unmitigated crap. The motor still comes on full throttle, there is no gradual increase of speed from low to high. AND !$%$ the part is more expensive than anywhere else. --- granted, shipping is free with Prime. Who makes, where can I get a part that will work properly??? Oh, btw, the wires are both white, but that makes no difference. I know, I dismantled the beast a second time and switched them after discovering the speed control STILL didn't work with a new part. If anyone can tell me where to get a real, reliable part, I would really appreciate it.

I work in F&B, and a VitaPrep/VitaMix is part of the standard arsenal in every commercial kitchen. Unfortunately, the faulty speed dial is something that plagues EVERY model that I've ever used. The last place I worked had 6 VitaPreps and only 1 didn't have this problem - probably because it was still very new. As much as I love VitaMix, I am disenchanted by their nonchalant, denial of the issue and continue to produce units with bad potentiometers. Most of them last less than a year in a commercial kitchen, before they start to hiccup and jump speeds unpredictably. Walk into a commercial kitchen and you'll see splash marks on the ceiling just to prove the point. What makes me irate is that I've contacted customer service in the past, only to have them tell me that they've never heard of this problem. I've actually thrown away two 5000 VitaMix's because of this. I was told that I couldn't get the problem fixed. Fast forward to this week when I happen to see this part on Amazon! I already bought a new 5200, but figured it was worth $24 to try and fix the fault one it replaced. I watched a YouTube video on it and its extremely easy to swap out the part. It took about 10 minutes. My old VitaMix now works perfectly!
