Bosch mfq 1901, suddenly does not start fix
ID: 118390
Description:
Steps:
- Using a flat head screwdriver carefully push the gray bar backwards.
- Open it like a suite case as there where hinges aligning with the flat underside.
- It should pop up fairly easy
- The blue line corresponds to how the plastic should align
- The red arrow shows where it has broken.
- Picture 2 shows the remainer of the plastic speed regulator
- There is a diode(black), a safety capacitor(white), another capacitor(blue) and a coil
- The white capacitor is an KNB1530 MKP-X2, 0,022uF, rated for 275VAC
- Use kapton tape or some other, thin heat resistent, low friction and electrically isolating tape.
- By merging the two broken pieces and putting one piece of tape(I used 8 cm to make sure other parts will hold) on each side of the broken area.
- Apologies of no picture of the result.
- You can also replace the part with a new one: Part# Bosch 640243 from https://www.bosch-home.com/de/supportdet...
- Make sure the spherical cable holder is in place(obviously not like in the picture)
- Use the same methodology as for dissasembly, let all parts stay in the left shell-piece
- Align the two shell-parts with an 90-degree at the flat bottom as there where an hinge there
- Do not use much force, this proceedure should be smooth, so be paitent
- Latsly, push the gray speed-dial area back with a small flat screwdriver to let the last gap dissapear
- I did put it on a heat resistant non flammable surface, set the speed controller to zero.
- Plug it out
- Repeat the first step but with the speed controller set to something else
- Mine spins better than ever! (Or maybe I was just exicted)
