Krups coffee gvx2 has power but does not grind, when button is pressed a slight spin and then nothing

SOURCE: Krups GVX2-12 Electric Burr... Problem:

First, unlock and unscrew the upper burr carrier. Clean and check the upper burr by gently running your finger over the teeth in the cutting direction. It shoild feel moderately sharp. If it feels very blunt, look at the teeth under a good light. If you see a substantial "flat spot" at the top of the teeth, probably the burr set will need replacement.
For the bottom burr, clean carefully its teeth, and the entire area in which it is housed. Include the outlet orofice as well. You may find a lot of oily deposits within here, so just clean them off as best as possible.
When all is clean, insert the top burr holder back in place. Screw it down until both burrs touch, then back it off (say) 1/4 turn, and lock.
Put some beans in the top, and switch on. Adjust the top burr until the desired grind is obtained.
The ground coffee should feel like a coarse sand when close to the desired grind size.

Mine had a piece of the top/bean lid broken off and lodged in the groove preventing the lid from going down far enough to release the safety switch which is on the right (as you look at the front) in the bottom of the groove. Note that there is another safety switch in the body of the grinder above where the ground coffee comes out that must be working as well.

SOURCE: GVX2 krups coffee grinder; how to open it?

I have the same issue. You need to take both dials off, then on the bottom, there are 4 tabs on the inside. Seperate the halves and you will see them. Towards the front and halfway back. Pry the halves apart enough to push the top towards the bottom and it slides apart pretty easy. The tricky part now is finding the replacement part. I have super glued my switch and I want to do something to try and repair it further. Maybe epoxy. I called Krups and they can't sell the part to me. I called one of their service centers and they can't sell the part to me. So, if someone knows where to get the part, I am all ears :)

SOURCE: Krups GVX2-12 Electric Burr - Thermal Fuse

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.
