I had the same problem and I manaed to fix my Cuisinart SmartPower Duet blender. There are two thermal fuses, one tape attached to each stator winding. Both of mine were blown.

In addition, when the fuses blew, it must have spiked the triac. I had to replace mine. It's the black 3-legged transistor looking device with a small metal heatsink attached to it. This gizmo directly throttles the power to the motor under control of the microprocessor. There are some guides on the internet on how to test it.

Also, the clutch was very hard to remove and needs to be removed to more easily replace the thermal fuses. I clamped down the end of the motor shaft to a bench vise real hard and then I used a 7/8-inch open-end wrench to wedge into the clutch prongs which made it much easier to apply torque. Remember that its screw threads are reversed from normal screws so that it does not unscrew during operation. You have to turn it counter-clockwise to unthread it.

Hope that helps!

    I completely disassembled my SPB-7, trying to find the "thermal fuse taped to the coils" but wasn't able to find it. Can you give me a link to a picture of what I'm looking for? I think it may have blown a fuse, but I don't know how to find what you're describing.

The blender will not turn on, the lights for each selection blink on and off but the blender will not spin.

Remove the bottom cover 1nd unplug the motor from the PCB, check the motor for a circuit with your multi meter. If the circuit is open then remove the motor and locate the thermal fuse attached to one of the field windings under the metal tie and tape for insulation. Test the fuse for a circuit, if it is open then you have 3 options, replace the whole motor, replace the thermal fuse only (it will need to be aftermarket as KA only supply motors complete) or just bypass the faulty fuse.

Wont turn on,just blinking light

This will probably need either a new thermal fuse on the field windings or a new motor.

Blender will not run. the power button is lite but

There is a 10 Amp thermal fuse (SF129E) that is supposed to create an open circuit when the motor windings exceed 133 C degrees. Although this fuse should close again when the motor cools down it can become perminantly damaged. Locate the fuse by following the black leads from the coltrol board to the motor brushes. It's inside a cloth insulating sheath secured against the windings with a metal strap and two ty-raps. I bypassed the fuse with a wire instead of replacing it. It would probably just blow again sooner or later. p.s. you need a T10 Torx screw driver to disassemble (screws under rubber feet) $3 at ACE hardware.

Do the lights come on but the motor won't come on? I had the same issue with my Cuisinart blender.

The problem is very often a thermal fuse. It protects the motor by opening the circuit if there is too much current or if the motor is overheating. If indeed this is the issue with yours, the device is less than $2 each is sold at Radio Shack but finding someone to replace it for you might be hard. On my motor there were two thermal fuses taped onto each stator winding. It took about 1-1/2 hours of work to remove and rework because of the unusual location.

Another part that often blows is the triac that controls the motor. This is around $4 but again, it's finding someone who can replace it with the correct replacement.

Hope that helps,

Cusinert blender

you most likely have blown the thermal fuse. I just fixed my blender which had the same problem but only after I bought a another base:< If you are a handy person, it is a very simple fix. buy a 10 amp thermal fuse from "RadioShack" for $1.69. Sadly, it is cheaper to buy a new blender than have it fixed at a repair shop.

Can't get my back to basics blender opened

I removed the motor coupling and after troubleshooting the blender found that the thermal fuse was blown. I think Radio Shack might have the fuse I need if not I know an online site that definitely does.

Lights blink, but Cuisinart Smartpower 7-speed wont turn.

The thermal fuse is blown. You can buy a replacement from RadioShack for $1.69 You have to remove the old one and solder in the new one. If youre "handy" its very easy. Take it to a repair shop, you pay about the same as a new one. Its too bad that most electronics made today are cheaper to throw away and buy a new one rather than fix them when they break.
