Question about Braun M880 MultiMix Hand Mixer
The switch only works in high. I can't figure out how to get the case open to either clean or replace the switch.
To disassemble: Pull the rear cover off by prying on the bottom edge. It snaps in and hinges at the top. Remove the small oval cover on the front by prying, then remove the phillips screw. Remove the protective slider off the bottom. The 2 case halves then need to be separated by prying.
My daughter dropped it (again) and speeds 2 and 3 failed to work so I disassembled it and found a broken center terminal on the power transistor. I saw a fine crack so I soldered it. I also added much needed strain relief to the heat sink. It works fine now. This is a poor design. The power device has a heat sink attached and there is no strain relief so the transistor can move back and forth at least 3/8". For a tool that sees a lot of vibration and shock, this heat sink should be tie strapped or have hot melt glue to prevent movement. Gary

My Braun M880 mixer switch went out today. Since it was already broken, I thought, what do I have to lose, and went about trying to figure out how to take it apart. Success! Make sure its unplugged first. There's a little plastic tablike thing in the front--squeeze the ends toward the center and it will pop out, or help it a little with, say, a blunt table knife. Then take out the phillips screw that you can now see. Then gently pry off the base (the part that sits flat on the table) Don't use too much force and you won't break anything. Then gently pry off the plastic slider on the bottom. Then work the seam where the two halves come together with your fingers, pressing down here and there until the two halves come apart. Now you can see the insides. What needs replacing is the electronic component. I found this part at smallappliances.com for 9.99 plus 6.99 shipping. Better 16.98 than $50 for a new one. The part is Braun 4642-634 PC Board Complete. It is a special order and will take 2-6 wks to arrive. I think replacing this will be rather easy. Study the online picture so you will know how much you are replacing with the new part. There are two metal tabs that fit down into the top of the motor and they pulled straight out (up) with pliers. The white electric cord has two clips that fit onto this board-they pulled off easily. You will see that the speed switch also fits onto the side of the board. This is as far as I can advise because I just ordered the part today. Good luck.
