Vitamix variable speed not smooth

Blender works well on high speed, but when increasing variable speed, it does not increase smoothly but in spurts. Also makes noise like an engine revving. When it gets to the higher settings, it runs more smoothly. Would this be due to a worn out drive socket/blade assembly that is slipping or would it be the variable speed assembly?

First of all, check if the warranty is valid. I believe Vitamix has a 7 year warranty. Your description does sound exactly like mine, which had a worn out potentiometer. I fixed my speed control without purchasing any spare parts by slightly bending the metal fingers to be tighter and cleaning them. I made a video explaining it here:

Some models had a weakness with the variable resistance in the rotary switch but your description sounds more like the main PCB or even the motor both of which are very expensive parts to replace.

SOURCE: sounds like gears are slipping

First thing is to find the small hole on the plastic piece below the drive socket and remove the silicone in from it. Next turn the drive socket until the little arrow on the drive socket lines up with the hole, then look thru the hole to see the allen wrench screw in there loosen screw to remove drive socket.

This problem sounds like failure of the Variable Speed Potentiometer component. Here is the most helpful Fixya article so far: http://www.fixya.com/support/t6032529-need_replace_speed_control
I have the same problem right now and don't want to pay ridiculously high prices for a small electronic component.
So far, this is as far as I've gotten in researching replacement parts:Vitamix Part #015955
Partstown sells #15955 for $23.39 on their website but I found out they charge $15 for shipping -- for a one-ounce piece of electronics. I won't pay to be ripped off on shipping so I won't buy one from Partstown until I've exhausted less-expensive suppliers. Here is the product at Partstown: http://www.partstown.com/vita_mix/vm15955
Another Fixya contributor, Robert Sadler, said he was going to try a generic potentiometer from Mouser.com. His descriptions are kind of vague for me. I'm not an electronics expert so I'm not very confident I can interperet his description:
"If you are comfortable with soldering, you can get a replacement part at Mouser.com. The pot is a 5k "slimline" made by Bourns, however looking inside the cover it looks like most pots would fit. I ordered one for a bit over $5 and will update when I get it with how it worked. You would just have to solder the existing wires to it." -Robert Sadler
I have no problem soldering the existing wires onto a new component but I don't really know what would be an appropriate potentiometer to buy as a replacement from an electronics supplier. In addition, Mouser's website seems to sell potentiometers only in bulk quantities of 5, 6, 12, or 45 items at a time. I just want one.
If anyone knows how to interpret Robert Sadler's comments, or has actually done this repair, please post below. I'm sure quite a few people would benefit from a high-quality repair at a low component cost.

Blender appears to be stuck on high. Today we changed the variable speed button blender still appears to be stuck on high.


The speed control usually is by electronics. The speed control switch will merely be telling the circuitry what speed is required but if the circuitry is faulty nothing will happen.

Kitchenaid ksb465 electrical noise.


Arcing at the brushes is normal although if worn down enough, they can skip since their travel is limited to avoid damaging the copper commutator.Look at the brush guides closely; the simple spring that supplies a little tension to the brushes will 'bottom out' on a slot in the guide once the brushes get too short.

The skipping might be due to the type of speed regulator that is used; an older type was mechanical and didn't regulate well at low speeds.

Waring blender shoots food out the top


Are you blending something hot? When you blend a hot item the steam that is released will increase the pressure in the headspace above the contents in the blender. The lid will eventually blow off to release the pressure.

To avoid this problem begin blending with no more that one cup of ingredients. Before turning the blender on, remove the center lid insert to allow venting of steam. Blend on low speed. As you blend you can add another 1 1/2 cups of additional liquid through the opening in the lid.

Trust this method will resolve your problem.

You're blending at a high speed and air is getting introduced. Try a slow blend speed. This should solve your issue.

I have this model and a vita prep 3. Both turn off when tasked with heavy blending. Is there anyway to increase their blending torque capacity? They used to be much better. They are not old machines.


The motors even if they not old blenders if they have work with too much load for along time then they have been overheated and thus they will trip overheat safety more sensitive. So now actualy you have less blending torque as you have describe. So now their is much posibilty if you continue to work it the same way you will finally burn the motor rotor so the damage will be grait.
So now not only you can not get more torque but you should try to avoid very heavy use in order to have them work for a longer time.
When you use with a lot of ice cubes try to cover them with a lot of liquids and always use the pulse mode to start ant the continues rotation.
Good luck
