Mixer is dead - Hobart D300 Stand Mixer

The WACEM (We Actually Collect Electric Mixers) web site has a downloadable PDF of the "K5-A, K45 Original Service Manual" in the "files" section.

This can help you figure out what has gone wrong with yours.

Have an electrician test the socket that the mixer plugs in to and see if there is electricity there. You might also plug in something else to test it yourself. If the socket its good, your mixer is "broken".
If the socket is dead, you need to reset the breaker, or replace it.
God bless your efforts.

I have answered your question Rosa. The question you resurrected from the dead is from January 2013!!

Replace the fuse located below the plug inlet on the mixer,(it is a 6.3A Fuse, 250V 5x20MM fuse from Radioshack) you have to remove the outer panel to access it. I did the same thing, it stopped working while I was mixing dough for bread, replaced it, good as new.

good day,
hope this link below will solve your problem.

It sparked, too? It's dead.

You need to remove the motor and find the heat protection fuse on the side of the windings. The fuse is rated at 140 and has a red tip. You might be able to get one from Radio Shack but Viking sells them for $3. Solder into place and take care not to overheat while doing so.

If the mixer does not work under load, then check motor , bearing , and control board.

If the mixer is less than one year old call manufacturer at the number listed on the owners manual.

Robbie. Are you getting any sound when you hit to start knob, or is it just dead silence? If you have dead silence, then it is definitely a power issue, which means it a couple of things could be conspiring to make your mixer not run. It may be a bad controller assembly (the speed knob), or it could be the motor, but either way it's something you can check yourself.
I'd start with the controller assembly and inspect that first. It's possible a connection has come loose. Unfortunately whole controller assembly is on a little PC board filled with resistors, capacitors and diodes, which was not meant to be 'home fixed'. My 'expertise' ends at being able to recognize a resistor from a capacitor, but I don't get much deeper than that. A local small appliance repair shop should be able to determine if the controller assembly is functioning properly or not.
The next possibility would be with the motor itself, but electric motors are pretty simple mechanisms and generally don't fail.
If your getting 'noise' from the motor but the mixer won't turn, then you've had a mechanical failure in the transmission box or planetary gear assembly of your mixer. The inspection and troubleshooting of the transmission is a DITY capability, particularly if your mixer is out of warranty. Just be sure to have the correct Part List manual around when you start to disassemble your mixer. You want Part No. 8212278 Rev D for your mixer, which you can download from KA customer service.
I hope this helps! Howard, Burke, VA

I had the same problem the first time I tried to make a small batch of bagel dough (very small!) I had to send it back for repair and wait.....sorry that the news is not better.
