Sensio Bella Blender Repair
This is a Sensio Bella Model# XJ-12412 Rocket Extract Pro Plus blender that my son wanted to see if I could repair for him. The light would come on but the blender didn’t work.
So I started taking it apart and figured that it was probably either a bad capacitor or a bad thermal fuse on the motor. Since it’s been a while that I’ve had an article to send in, I checked the capacitors and components on the power supply PCB first.
The next two photos show removing the fan and blender wheel so I can take the blender apart. If you repair one don’t forget that the blender wheel nut has left handed threads.
Everything checked to be good on the PCB. I checked the Triac, diodes including two Zener diodes (6.8, and 5.1), capacitors, transistors, and checked for bad solder joints, but found nothing wrong. So I knew that the thermal fuse on the motor was bad, and I was right. Without making this repair too long, I’ll get to it.
I removed the control pad PCB to make sure everything was ok, and it was ok. Then I removed the motor and looked for the thermal fuse. I could tell by the shape of the wire which one had the thermal fuse in it. I clipped off the zip ties and removed the metal strap from around the wires. Then I cut the paper that wraps around the wires so that I could separate the wires and start removing the shrink-wrap from the thermal fuse as you can see in the photos.
In the next several photos I show removing and replacing the thermal fuse with a new NTE 117C thermal fuse. The thermal fuse has the number 116 on it but the package says that it’s a 117C. The part number is NTE8115. I don’t trust crimp clamps – I always solder the wires in them after applying plenty of flux.
You can see in the photo above how the leads of the thermal fuse were bent – probably during installation. You should not bend the leads like that! No wonder the thermal fuse only lasted one year!
Anyway, the blender is repaired and back together. I’m sure my son will be happy that he doesn’t have to buy a new blender. And I’m glad that I repaired it and saved the blender from the garbage.
My son is very happy that he has his blender back working great! In the photo above, he’s making a very healthy smoothie with strawberries, kiwi, and other good stuff. I hope you enjoyed this repair.
Also, for those interested, I’m about halfway through Part 1 of my Accutron 214 article. So it shouldn’t be much longer before I send it in to Mr. Yong!
