Cuisinart SM-55 Stand Mixer - Answered Questions & Fixed issues

Gears inside are probably broken, I have 3 of them to do this (i use them commercially) and decided to open one up to see and the gears were broken and stripped. So far I have not been apple l able to find any replacement parts.

The shaft of the beater is bent. After frustrating discussions with Cuisinart customer service, I was able to free my beater. First, you will notice that the beater screws onto the shaft. Unscrew it. Then, take the nut off the shaft. Next, put a wrench on the shaft that is only slightly larger than the shaft, followed by a washer. Next, screw the nut back onto the shaft. Finally, holding the wrench at the end, hit the wrench close to the shaft with a hammer. If the shaft doesn't come out, hit harder. Since the shaft is bent, you'll need to purchase a new beater.

Here's what really happens. The hook has a shaft screwed into it with bayonet fittings that lock into the mixer. The shaft has a locknut where it screws into the hook. If the locknut becomes loose then the shaft can screw in too far making removing from the mixer almost impossible. Try to get a slim wrench onto the locknut and loosen it off enough to allow the hook to be unscrewed. After the hook comes off, move the locknut down the shaft until the whole assembly can be removed from the mixer. Re-attach the shaft to the hook making sure that the exposed portion of the shaft is long enough to allow for easy removal from the mixer. Tighten the locknut and you will never have the problem again.

You may want to look at the following components on the circuit board and replace them as necessary. If there appears to be no power to the machine (clock), the machine may have received a power spike from an unclean/fluctuating power source. Look at resistor R5. If it shows any signs of heat damage, replace it. Then look at diode D3, which has been the cause of malfunction on my unit for four times already. Replace this diode (10V, 1.3W) and it should run again. This diode is working like an over-voltage protection fuse (which should have been built into this machine with easy access in the first place!) and since it gets fried so often on my unit I'm planning an illustrated writeup on how to mod the board to make exchanging this diode easier and without disassembling the machine.

Make sure the plug is securely plugged into the wall.
Next, remove and reattach any mixing arms etc that may be attached to the mixer. Having one not attached properly can result in a start, start.
If problem persistes make sure the speed is reset.

If problem continues, here is an excerpt from the user manual found here.

http://www.cuisinart.com/share/pdf/manuals/sm-55.pdf

Problem: Your stand mixer has an
overload protection device and if
overloaded, it will shut down to protect
the motor.
Solution: In the unlikely even that this
happens:
• Turn off and unplug the unit.
• Reduce the load by removing some of
the ingredients, and allow the mixer to
stand for a few minutes.
Plug in and reset the speed. If the
stand mixer does not start when you
press the on button, allow the unit to
stand for additional time.

If you are still having trouble, the product comes with a 3 year limited warranty, so if you're bought it within the last 3 years it may be covered.

Good Luck!

Hi,
It sounds Motor Control Board got problem as you hear relay click but motor does not get power to rotate from motor control board.
It is electronic hardware failure issue, its not user level repair and professional can do it.

Hope these info will help you.
Thanks.

I just got my dough hook unstuck! The problem was the bolt at the top of the dough hook. This bolt is used to adjust the height of the dough hook. This bolt came loose while mixing and went up towards the mixer. The force of the spinning actually tightened this bolt against the mixer so when I tried to release the dough hook by lifting and turning, it wouldn't lift. The bolt was in the way! The solution is to loosen this bolt. You'll need a thin wrench that's about 15 mm. You can test loosening this bolt on the other attachments since they loosen in the same manner. You'll have to bend the white shield down slightly to get the wrench in there. It's a tight squeeze even with a thin wrench. Hold on to the lower end of the dough hook and turn the wrench counterclockwise when looking down at it. Once you loosen the bolt, you'll be able to turn the lower portion of the dough hook to lower it. Then you can lower the bolt further. Once you have them low enough, you can remove the dough hook like normal - lift and turn. Sure beats boxing it up, shipping it for repair and paying for shipping both ways!

First try adjusting it. The head may be set so low, the head can't latch. Does it latch with no whisk attachment? The video shows how to adjust it with the whisk in place using a dime.. If that isn't the reason, spares are available and dealer service is available. https://www.google.com/search?q=cuisinart+5.5+stand+mixer+parts ..

Hi, Please disconnect the power from the device for 5 minutes, reconnect and attempt to change the speed again. If that does not work, please eject the beaters and attempt the change the speed with them ejected before re-adding the beaters. Thank you.

I would take a swag at it and guess that the speed control has a variable capacitor consisting of a circular plate and wiper. The plate is a series of contact points that switch the speed control into the circuit. You are missing some of the contact points in the middle of the switching cycle or the wiper is not making contact at that part. You would have to replace the speed control part, but finding the part would not be easy and repairing it was not anticipated due to obsolete thinking on the design of the product.

Ken: most small AC motors require a starting capacitor, where it ups the power on one of the field magnets that give an initial spin to the armature. Since the 120 volts are equally dispersed over the field windings.If this capacitor is missing or shorted the motor will just hum and not rotate.This capacitor or its equivalent is mounted on a small circuit board somewhere encased in the base of the blender.Unless you are a skillful technician and can trouble shoot the failings and be able to get a replacement part, you would have to pay someone else to repair it, that is if you could find someone who repairs small applainces, and it would cost you much, more than the 100 bucks you paid for the blender.

Take it back, it is under warranty right, you said it was taken out of the box.

These show up on E-bay all the time.

The shaft of the paddle is bent. After frustrating discussions with Cuisinart customer service, I was able to free my paddle. First, you will notice that the paddle screws onto the shaft. Unscrew it. Then, take the nut off the shaft. Next, put a wrench on the shaft that is only slightly larger than the shaft, followed by a washer. Next, screw the nut back onto the shaft. Finally, holding the wrench at the end, hit the wrench close to the shaft with a hammer. If the shaft doesn't come out, hit harder. Since the shaft is bent, you'll need to purchase a new paddle.

does it get power ? there is a thermal fuse inside the machine R&R and you might get one at Radio Shack 8 to 10 amperage value for about $ 8.00 if you know how to do electronics ...good luck ...15 minute job

Follow these steps to find out the problem else call Cuisinart { 1-800-726-0190 } for help :
•1
Remove the back cover by removing the small Phillips screw at the top of the back cover.
•2
Place a rag or cloth over the spring to keep it from moving.
•3
Plug in the mixer.
•4
Move the switch lever to "Stir." This may or may not start the motor.
•5
Turn the two adjusting screws counterclockwise evenly until the planetary turns approximately 60 times per minute.
•6
Test the planetary by holding a right hand finger lightly across the beater shaft. Count how many times the shaft touches the finger in 15 seconds.
•7
Turn the two adjusting screws until the shaft brushes the finger 15 times in 15 seconds.
•8
Lock the two lock nuts using an 11/32" wrench. Check the speed again.
•9
Make further adjustments, if necessary, without loosening the lock nuts on the control board. Unscrew the two adjusting screws.
•10
Move the planetary to speed 6. At this speed, the planetary should turn 180 times per minute. Check speed as you did for the first speed. The planetary will brush your finger 15 times in 5 seconds if the speed is correct.
•11
Turn the adjustment screw at the bottom of the control plate if the speed is less than 15 times in 5 seconds.
•12
Check the revolutions again. Keep adjusting the screw at the bottom until the correct speed is reached. You don't need to lock down this screw.
•13
Test all speeds from "Stir" to #10. If "Stir" and #6 speeds are properly adjusted, the other speeds should be correct automatically. If you notice a definite change in speed between #8 and #10, you have adjusted the mixer speeds correctly.
•14
Replace the back cover and screw in the back cover screw.
