Question about Krups KB7207 4 Speed Blender

Open Question

My Krups blender stopped working suddenly.

My Krups blender stopped working and I am wondering if it's a fuse or something. I bought it new a couple years ago and it always seemed to have a burning hot smell when it ran. For much longer than the typical "new" smell for electronics lasts... I can't find a small appliance repair place anywhere and my husband asked, "Do people still repair those?" I'm beginning to think gone are the days and am contemplating letting him tear into it even though it was really expensive. What do I have to lose? lol

SOURCE: Krups blender drive gear

Ed,

The problem I had was removing the grey rubber drive. The solution is that it screws off not pops off. The trick is to use narrow needle nose pliers to grab the post that attaches to the motor and turn the rubber drive counter clockwise. Removing the motor becomes easy. Pull out the 4 rubber feet under the base and the screws will be exposed. However my situation was the grey drive gear was stripped and would bottom out. My solution was to use a same size lock washer as the washer between the post and the drive. So far so good! If it fails I will need to buy another grey drive. Myron

Repairing the blender:
My guess: You worked the motor too hard on your last blending session and it overheated. That will cause a thermal fuse inside to cut off. The blender won't work again until you replace the fuse but otherwise it should be fine. The fuse looks like a white diode and it will be attached tightly to the motor with a nylon strap (so that it can pick up the heat of the motor). The leads to the fuse are shielded with heat resistant nylon wrap. You will need to remove the rubber drive gear in order to remove the plastic house so you can work, although if you are really handy you might be able to at least test the unit by only removing the plastic bottom on the base unit.

To remove the plastic housing, remove the little rubber feet and then remove all of the screws on the bottom of the unit. You may need to buy a bit set for tamper resistant screws (I ***hate*** those), I don't remember. When the bottom is removed, you will see that the there is a screw head on the bottom of the central motor shaft. You can use a screw driver here to hold the motor from turning, then you can carefully use a pliers to unscrew the rubber drive gear on the top of the base unit (try not to damage the rubber). With the gear removed you can get access to the wires.

To test the fuse unit, just check its continuity. Short=good, open=bad. To further test, short out the fuse with a jumper cable and your blender should work.

EPO (Electronics Parts Outlet) in Houston, TX, has the replacement fuse unit. I don't know that they like mail order.

SOURCE: How can I open akrups gpa3 blender.It does not work only 3 years

The body of the blender is held together by three cross head screws two at the base which are clearly visable and a third which is concealed by the pulse on/off switch which you need to prise off to reveal - small spring to rear to catch! Our blender went totally dead due to a blown internal fuse which I have now replaced and hey presto we are back in action.

Brand new. Pulse feature stuck ON. Tried OFF. Tried unplugging. Still only pulses, no blending. Tried a dozen times.


So when plugged in it always just runs on the pulse? I would assume that this is an issue with the control board inside. If this is brand new return it to the store and exchange for a different blender.
You could also contact Krups to see how they work their warranties but you most likely need the control board replaced and that is something a service center would have to do for you.

Here is the information for contacting krups:

How to disassemble krups gma1 blender


Myron's tip about the need to unscrew the grey rubber coupling is correct, but I was unable to grab the post and hold it still, even though I was using narrow needle-nose pliers. I just could not get underneath the rubber coupling. I ended up cutting the rubber piece off the steel cord inside the coupling, which exposed the threaded post. I could hold the post stationary from above while I unscrewed the steel cord. My old coupling was stripped and worn out, so it did not matter. A new coupling can be ordered cheaply.
I found that it was not necessary to open the housing of the whole appliance as long as you can hold the post stationery. And even if you can't grab the post from above, opening the housing won't help because it won't come off until the coupling is removed at the top.
If you need to open the appliance for anything else, Myron is right, you need to remove the 4 rubber boots on the bottom to expose the screws. The screws are so-called temper-proof screws for which you need a special screwdriver. The screws are called "pin-in-head-star". But removing the 4 scows is not enough. You also need to unscrew the coupling at the top.

take a flat head screw drive to the bottom of the blender and us it to hold the blender shaft in place while you turn the gear by hand or with a plyers (it is reverse threaded) and it should spin right off. when you get the new on it should spin right on.

Blender suddenly stopped working while in use, lights are on


The motor has burned out. Check with the manufacturer about warranty status for the blender or exchange it.

Krups 239 blender drive gear.


Like you, I am all for repairing and keeping the world free of blenders that only need one part replaced. The rubber coupling was easily ordered online, the challenge I later found was to remove it without losing my sanity. After messing up the side grill of the blender pretty good, I realized there is an opening on the motor casing that allows access to a "gear" that is firmly attached to the axle where our little friend will hopefully screw on and restore the contraption to a working state. In order for you to see (which I must warn you, it's not much of a view) through the grill you will need a flashlight or book light. Towards the top of the aforementioned gear (not the rubber part) there is a groove in which a flat screwdriver can easily fit immobilizing the axle and allowing you to easily unscrew it. Oh, but wait, I forgot this is the faulty part and it will spin without the slightest torque on the axle thus never loosening or getting it unscrewed. My solution to this problem was to surgically remove as much rubber as possible to allow me to attach my vise grip to the nut and finally put this thing out of its misery. Using the same procedure of inserting the screwdriver to immobilize the axle I was able to screw the new part and voila the blender is fixed!!!!
