Blender won't start at all, how can i even tell if the fuse is broken

Owned this blender for just 4months. Everything was fine when I used it three weeks ago. It din't even overheat. Now, all of a sudden, it just won't start.

I can't find my maual to troubleshoot and I have no idea what might be wrong.

    I bought my blender brand new didn't use it for a month and threw away the box and the manual. I realized later that when i went to make a margarita it wouldn't start. I tried unplugging and restarting it. checked to see if it was the lock on the handle. that could be the problem but i don't know if i'm doing it right. any tips?

There's a safety lock built into the handle of the jug. If the jug cover doesn't key into the lock properly, the motor base won't start.

Old blenders used to be able to start without putting the jug in place at all. I think this helps you know when the jug is in place properly.

It's indicated on the carton box; somehow I can't find my manual.

Cheers!

I know this is an old tread but this might help others. On the 3902 blender, pull the rubber feet off and remove the 4 screws. Pull the bottom black plastic off. Un-snap the black plastic piece housing the control arm that varies the speed. You will see a PC board with one screw in it. Remove the screw pull the PC board. There will probably be an un-soldered solder joint at the transistor component. It will do no good to resolder it as it will just melt off again. It is best to run a heavy wire directly to the lead of the transistor (on the top side of the board) the other end of the wire to the widest part of the foil trace on the back of the board. You will have to scrape the green paint off to expose the silver trace for soldering. I used an electric eraser but a knife blade works too just don't cut through the trace. 22 gauge wire or larger will work. This is so much easier as it sounds as long as you can solder. The large wire will not get hot enough to melt the solder. By the way I know its not a transistor, but it looks like one, it is some kind of gate controlled diode

    Make sure you solder to the same trace that had the missing solder joint.

Why won't the blades turn?


One or both of the drivers are broken, check the clutch on the top of the motor and the other one on the bottom of the beaker. You will find something there worn out or broken.

Broken blade housing


I have the whole blender. White with a red glass pitcher. I have only used it twice. For ice. What would you pay for the whole blender? You would then have a back up of it all. Works fine. Just too heavy for me.

My kitchenaid blender does not whizz around when it is put together> the couplking spins when the glass part is off that is, when it has nothing on it> the coupling does not look used or...


There are really only two reasons why the blades won't spin, either the coupler is broken, or the blade unit is damaged. Check the picture of the blade unit here: Check pictures of the coupler here: Hopefully it should be obvious whether the coupler is ok, if it is, are both wings on the wingnut under the blade unit?

Breville blender won't turn on. The on light is flashing red instead of solid blue. Worked fine a few days ago.


FIXED IT - It's the screws on the bottom of the jar assembly, where the blades are attached. There are 4 Torx screws - star-shaped - and when these come loose over time the Blender will start to operate only sometimes. Eventually it will be never.
Tighten these four screws and everything will be fine!

HOW DO I REPLACE THE FUSE ON AN OSTER BLENDER MODEL 4094


unplug it.... use a small plastic screw driver or even a metal one if you are careful... pry gently up on one side of the fuse... it should pop out of the holder. when it does... use your fingers to grab the end and pull up. the fuse is replaced by placing it back into the holder and pushing down until each end pops back into the holder

Help me revive my dead Oster blender


Check the motor brushes. They may be worn out. Also, since the 1980s, many electric motors have a thermal fuse in them. This unit "blows" when it gets to a certain temperature.

This fuse looks like a 22-caliber bullet and its pointed end is usually colored. If you have an ohmmeter or continuity checker, see if current will pass through the fuse. If not, you can try to replace it. Most times, the fuse is attached with crimp-on connectors. Replacements can be soldered in, if you put a clip-on heat sink between the fuse body and the soldering iron.

Cuisinart sealing gasket


The gasket goes between the cutting assembly and the glass. So you slip it on over the top of the blades and then put the glass jar over top of that. Screw the bottom cap on to tighten everything together.
