Krups GVX2-12 Electric Burr - Thermal Fuse

I believe my coffee grinder overheated. Grinding slowed to a growl and then stopped completely. Grinder body felt hot

Can I replace/reset the thermal fuse myself? What is the best way to open the grinder to check the fuse?

    Adding to my description of my problem, the on/off button still lights up, but grinder will not operate.



    If the thermal fuse needs repair, would the on/off button still light?

  • Craig W Jan 28, 2008

    I have the same problem, it will sometime work if I move the timer on the front all the way off.  Sometimes the motor will bog down to a growl. I have checked the burrs and switches and they seen to be OK.   

  • Shanerh Jul 24, 2008

    Yep, I have the same problem.  Before it has come back but now it is just stuck.  I have taken out the burrs and put it back together but now it even seems like that isn't fitting back in right (when I did get it to grind again it was very course and I can't move the dial on the side!).

    Sounds all too familiar. Mine just turns slowly like it's got string wrapped around it.

  • rmb54 Aug 09, 2008

    Yes I have the same problem. The grinder has stopped. The blue light comes on but the motor doesn't run. The book says a thermal fuse has been released. How do I reset it?

  • jobaio Nov 02, 2008

    My grinder does the same thing - the blue light comes on but nothing happens

  • Anonymous Jan 31, 2009

    It was as if the timer stopped working? went slower and slower, then would not work any more.

    This seems to be a common problem.


  • Marlin Clayton Mar 29, 2009

    Blue light comes on; nothing happens. No noise, no humm, certainly no grinding.
    I expected more from Krupps....

    Was grinding away, then started smoking and stopped. On/Off button is lit when pressed but nothing happens. Can't figure out how to open the thing without taking a hammer to it..... Some help from Krups would be nice. Oh well, they made the sale, that's all that matters, right?!

Open the grinder by removing both knobs.
The front knob is held in place by friction. Use two flat head screwdrivers to pry it off.
The side knob is held in by tabs you have to push. Pry forward to expose the tab, and use another screwdriver to press the tab, and use the other screwdriver to press the tab on the other side.
Now look at the bottom of the grinder. There are four tabs on the outer shell, use screwdriver s to pry the tabs to separate the bottom of the grinder from the shell, and pull off the shell. Your fuse should be attached to the motor wiring coil.

My grinder stopped suddenly. Open the cover(s) by prying at the cracks with a butter knife or flat head screw driver.
The thermal fuse was good in my case, as were the interlock switches.
The circuit board was burnt around a large power resistor but I could figure out which component was bad. I simply cut out the timer control completely. One of the black motor wires now connects to the red wire from the bottom interlock switch and the other black wire connects to the blue AC power wire. I may put in a button switch but it works great by using the lid interlock as an on/off switch.

Thanks Rleyden.

Your solution worked great.
My Krups grinder also stopped working all of a sudden. It wasn't the safety switches or the on/off button. Seemed to be something with the timer. When I switched on the grinder it worked for about 1 second and switched off again.

I removed the whole the timer mechanism.
One of the black motor wires now connects to the red wire from the bottom interlock switch and the other black wire connects to the blue AC power wire. The lid interlock now functions as on/off switch.
Thanks Rleyden for your suggestion.
Cheers AD

The problem I had with this grinder is that it would not come on at all. Nothing. No blue light or anything. I took it apart following handhyranju instructions above. It turned out the safety switch for the bean reservoir hand fallen out of it's position. The plastic clip that holds the switch in was cracked and would not longer stay in place. It is a thin plastic clip held in place with two screws. We had this grinder for about 14 months before it broke. (Krups, if your listening, I expect better from you!) Anyway. I put the clip back the best I could and put several layers of duck tape over it as a quick fix. (Wife wanted coffee the next morning!) In hind sight I think fashioning a small "L" bracket out of a thick plastic, putting a hole in one end of the "L" bracket and screwing that over the broken clip would be a stronger fix.

The grinder stoped grinding coffee


many grinders have resetable termic fuse, some of them require manual reset, so you should search for termic fuse attached to body of motor(open the grinder from bottom) usualy they are round black termofuses with red reset button.
usualy this happenes when we have loud music and we dont hear that grinder is on and he works long time.

Grinding setting is one simple operation but requires bit patience:

  1. Turn on your grinder and continue setting to fine while burrs are spinning, you stop when you hear metal to metal touch sound(burrs maximally closed finest grinding)
  2. From that point go back quarter of revolution and mark the spot where you stopped with marker to body of grinder and setting plate with one line
  3. Grind little amount of coffee only to fill one sector of dosser than test it at your machine (if it leaks too fast and with yellow color of cream you should go to more fine>><< if it does not leak from the filter holder or it leaks very slow you go to in opposite way.
  4. You test grinding few times bit after each reset of plate grind little amount and take that in one other pot (that will provide to have pure new granulation)
After setting measure the grounded coffee that comes out from dosser it should be about 7 grams, better measurement you can get if you measure 10 doses in one place because you don't get never same amount from 6 sectors of dosser

You may really have overheated it and it may not have a self resetting thermal fuse. Probably best you say nothing and take it back for repair or replacement under guarantee. When you are up and running again do much less grinding at one time.

You will have to disassenble the grinder by removing the screws from the bottom of the grinder. You should be able to get to the thermal fuse once you gain access to the insides.

Well worth attempting the repair if you have the replacement thermal fuse needed and can handle a soldering iron to unsolder and soldering needed to remove and replace the failed part.

The thermal fuse isn't like a normal glass tube automotive fuse, but you should be able to get a replacement one from Radio Shack, if you can't get one from the manufacturer.

Hope this helps you get it fixed and best regards!
