SOURCE: Bosch Cooler is broken

im taking it that the cooler you refer to is actually a general fridge. if its not working, it is either your th/stat which has not reset or if not, assuming your fridge is an auto defrost, look behind the freezer and locate the timer. you should see a plastic knob plus/minus in the middle of the timer. turn the knob and listen if refrigerator comes on. if not call a tech.

SOURCE: How does one remove a

twist the collar around where the blade fits in the saw. It will lock in the open position. When you insert the new blade, do so firmly until the collar releases locking the new blade in place. Give a tug at the blade to make sure it is locked in.

SOURCE: installing carbon brushes on Bosch WFK 2401

Remove rear panel of washer.
Remove drive belt.
Unscrew the 2 bolts that hold motor to tub back.
Remove motor plug
Lever notor back with a screwdriver or similar, keeping a firm hold on motor.and remove motor
At the rear end of motor away from pulley you will see the brushes and the armature.
Remove brushes, and if there is less than 4 or 5mm of carbon left, then replace them.
Lightly clean the armature with emery cloth.
Refit in reverse order. Test.
Plz rate my solution.
Thanks.

SOURCE: Bosch rotary hammer (model # 11230EVS) drill will not rotate

There is a clutch in the main spur wheel of the unit. These sometime begin to slip, on rare occasions they will slip to the point where the drill will not rotate. If you are interested the part number for this clutch is 1617000817.

Need Fan Switch part 19-11-915-01 Model H30HQS


Ouch.
Looks like you are out of luck.
Even the compatible Bosch part AP2831861 is discontinued.
As shown below, it appears to be just a standard, variable-speed switch.
I suggest trying to find one at the hardware store that is the same size or trying check an electronics shop that something similar.
Good luck.

Variable speed not working


The variable speed function is controlled by the switch. If you only have off and full on, the only fix is to replace the switch (Bosch Part Number 2607202013).

I have a Bosch 1/2"


Sounds as though you are on the right track. I would take it apart, and see if the trigger could have some dirt or other material causing it to stick, or is it worn to the point that it needs to be replaced. Good luck!

My 1199vsr hammerdrill from Bosch will not start. A couple months ago, I lost variable speed (ran at full rpm or nothing). Noticed a lot of comments on line about this model not starting. Wondering if...


It could possibly be that your brushes (Bosch part number 1617000525) are worn down to where the drill won't work any more. Take the two screws out of the back of the handle and remove the housing cover to check them. More likely your switch (Bosch part number 2607200918) has gone bad. If you lost the variable speed a while ago that was a sign the switch was already breaking down. Also located inside the housing cover, you can check for burnt wires or melted plastic around the switch but it is possible the switch is bad without having any visible problems outside. Fairly easy to replace, just make sure you connect the four wires to their proper contacts.

Ground speed slows under pull at high variable speed settings.


Take off the plate around the shift lever between your legs and take a look at the belts. Most likely they will be in poor condition. You can even leave the trans in neutral, start the engine and move the speed selector through the gears and observe the belts in action. They do the same in neutral as in gear when you let out the clutch with the engine running. You should be able to see what the problem is, It will either be one or both of the belts or possibly the needle bearings in the vari-speed pulley itself,

1) No variable speed; 2) Grinding sound when using <high2speed>, although drill still works


starting with the variable speed the switch part # is 2607200457 and list for 47.58, the gearbox part # is 2606200930 and lists for 75.90 and lastly the motor part # is 2607022865 and lists for 75.90, the grinding could be the motor bearing going out or the magnets cracked, if you want to tackle this I suggest going to Boschtools.com and on the left side towards the bottom type in your model number so you can look at a breakdown of this tool. Before I started spending that kind of money I would think about possibly replacing it. If I have helped you would you please rate my response accordingly and Thank you.

I have a bosch rotary hammer 11245evs and it was working when i put it away in its case, now it will not hammer. Drills ok. larry


They are filled with a special grease that comes from Bosch. It sounds like the impact bolt or the striker pin in the unit are not moving the way they should. These are the pieces that work together to create the hitting action. About all that can be done now is the unit has to be dismantled to get those to pieces moving again. Bosch makes what they call service packs for all thier hammers. They have all the o-rings and grease to get your hammer working again. A Bosch service center can supply you with the kit. Ask for P/N 1617000225, or they can take care of it for you.
Hope this helps
