Question about Cuisinart SPB-7 SmartPower Work Top Blender
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.

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
