I've used my blender for about a year now without problems to make fruit shakes. Recently the blade assembly no longer spins. The blender cannot spin the blades anymore and the motor stops. The blade assembly has almost seized. Twisting it my hand is very hard and only moves very slightly.
Will loosening the bold on the blade assembly work? What about a food-safe lubricant? I tried soaking the assembly in hot water for a while and that loosened it temporarily but didn't fix it for the next time I tried to use it.
I'm considering having to buy a new blade assembly (~$25).
I had this problem and, after seeing these posts, was motivated to avoid paying the cost of a new blade unit. Here's how it can be fixed:
1. Take a kitchen hotpad and hold the blade (top) side of the unit in your hand as you unscrew the rubber gear on the base. This is a left-handed screw, so you must turn it clockwise, to free it up. This should be doable by hand. Be careful, removing the gear exposes a washer note which side is up, and place both the gear and washer aside.
2. With the blades held in the hotpad, unscrew the top nut, again clockwise. This takes more effort, but it will eventually give way. As this nut comes off, it exposes a rectangular post, to which everything is attached.
3. Remove a washer with a rectangular cutout. Make sure you remember which side is up (I think it makes no difference). This may require some rocking to remove the washer from the round-threaded end. It will come off.
4. Remove both blades in a similar manner. Note their orientation, which is important.
5. Next, remove a rubber gasket. On mine, it has a groove which is asymmetric. I don't think the orientation is important, but, again, you may want to note it.
6. What is left is an axle inside a sleeve. There are no bearings. In mine, I had to tap/drive this out. Take a flat-ended rod (ideas: I used the hex-shaped post end of a nut socket. An old drill bit you don't care about, rotated would also work). Place the unit on the edge of the counter, up-side pointing up, in a way so the bottom end of the axle could fall free when you drive it out. Gently tap the axle through the unit, using the helper tool when the axle is within the sleeve. It will drive completely out.
7. Clean everything. I simply scrubbed the axle and took a small brush to the inside of the sleeve. This doen't need to be perfect, but anything left on either surface may ultimately impair the functioning of the axle.
8. Lubricate the axle with household oil or a dab of grease. You will find that the axle will now slide into the sleeve fairly easily (I had the best luck from the top.)
9. Reattach the base gear, then the top in the obvious order. Everything should spin freely from this point on.
REMEMBER: always use the hotpad whenever you grip the blades and to tighten the bolt on top so that the axle protrudes slightly above the nut.
Good luck!
I just pulled a nice cuisinart blender out of the dump and it had this exact problem. I DID NOT have to disassemble the blade as above. I removed the rubber gear as described in #1 above (and got a small cut, definitely use care), then couldn't remove the nut holding down the blades--but I didn't have to, the entire shaft pushed out the top with a little effort, blades attached. I ran a drill bit through of the correct size through the hole (can't remember the size but it should be obvious) and lubed it and now it's perfect!
I figured this out on my own, I used a piece of cloth and pliers to hold the blades in place and a socket to remove the nut. Then just a philips screwdriver to tapout the spindle. I used coconut oil to lubricate and a refresh any of the gaskets. Spins like new!
I followed the instructions from activadesign and it worked great. I used some sewing machine oil to lubricate the shaft in the bushing after cleaning it so it now turns freely. Also the motor had stopped turning. I thought there might be a fuse blown or a thermal overload switch to reset. I disassembled the based and looked at both sides of the printed circuit board. I saw no fuse or switch so I reassembled it. I plugged it in and voila, it worked again. I guess there may have been some safety shutoff that either needed a cooldown period or a capacitor to discharge or something. Anyway the blender works again. Thanks!

I will also check the blade bearings,if the blades does not turn easily and the motor brushes,they get worn with time and theybare esay to check and replace.
I wish you good luck and hope you saty away from buying the motor, thats a
very expensive ordeal.

Replace the blade assembly immediately. They are available from Cuisinart's website. Sugars and other stuff can gum up the blade assembly over time, so it will periodically need to be replaced. A quick and easy way to keep the blade assembly clean and working longer is to put water and a drop of dishwashing soap in the blender after use and run the blender at low speed for 15-20 seconds - an old Osterizer trick.

I think the ice was too hard for a hand blender. I think the impact has caused the blade to separate from the shaft or caused the shaft to separate internally. If your blender is still under warranty you might be able to get it fixed. Note: none of the "Smoothy" recipes in the manual call for ice. One uses ice-cream. One uses "partially thawed frozen strawberries" and one uses sherbet.

You have to unscrew and disassemble the blades - pretty easy, just take two rags and grab the blades with one (so you don't cut yourself), and then turn the rubber piece on the other side COUNTER CLOCKWISE, opposite of what you would do to loosen. the rod that runs in the middle that's connected to the blades on mine was all corroded, so I sprayed it down with WD-40, took my Dremel to it and smoothed out the corrosion, added some fresh grease ($2 tube goes a long way), washed the other parts with some Dawn and dried completely, reassembled and it runs much better! Not sure how long it will last, but I have a feeling that one time I ran the blender for a long time instead of pulsing, and the grease that came with it couldn't handle the heat from it turning so long. Anyway good luck!

Yes there is, however unless you are very mechinal incline I won't suggest that you try to replace the defective terminal fuse. This is cause by running your blender continuous. Let me know if you are welling to do the repairs yourself, so that I can give you the directions. Sign, Spurs21

I've had the same problem on my Cuisinart BFP-703 SmartPower Duet blender. I've now gone through 4 blade assemblies (at ~$15 each). In every case, the blade assembly gets tighter and tighter to the point where I can't even turn it by hand. When I take them apart to determine the cause, the chrome plating on the brass shaft has come off in many places making the surface of the shaft very rough. I'm not sure if this is caused by the eventual loss of lubricant followed by damage from resulting wear and heat or if it is caused by liquids seeping into the shaft and corroding the chrome plating. Either way, I've been very careful with the last few blade assemblies to avoid soaking in water or using detergent (which could wash away any lubricant), yet the problem still occurs. I believe it is a design flaw since the chrome plating is very thin, and eventually wears off no matter how well it is taken care off. I've tried mineral oil and other lubricants to no avail - the rough surface of the shaft still continues to keep the blade from spinning freely. Therefore, unfortunately, I believe that replacement is the only solution. I've considered buying a different brand blender, but it seems a waste of an (otherwise perfectly good) blender and food processor. Also, who knows what other problems another brand may have.
I've had the same problem and just today had our second replacement blade seize. I too have tried very carefully to clean and dry it immediately after each use. After my third blade (in total), I don't know whether or not to buy a different blender $70-$80 or buy the replacement blade every 12 to 18 months. I've really enjoyed this blender when the blade turns.
Same problem, the blade stops spinning and puts a strain on the motor. I've unscrewed the top nut and then re-tightened but not as hard, but then the same thing happens again. When motor is straining you can smell it actual burning the motor. Very disappointed with this product(less than 2 years old).
I beginning to have the same problem. I think the grease used in the blade assembly is the culprit. Since I wash the blender so much the grease that originally came with it is wearing thin. But where I can I find a replacement that suitable for kitchen use? This is the best site I've found so far (below) but it seems like they sell in bulk. What a pain.

Blender blade assembly would not turn. It's even very hard to rotate it by hand. Since blender blade is hard to rotate, it's causing blender motor(base) to heat up and it starts having odor of plastic burning in the motor. The blender sounds very rough like it's ready to die on me.
I have face the same problem with my old blender blade. It stop spinning after sometime and the blade is hard to rotate as well. While i was thinking of replacing the blender machine i came across food grade grease ads from Bechem Lubricants. Once i apply the oil i have never face the some issue again.
