Maybe someone had similar experience with bosch mrc23evsk router.
I stays mounted in the fixed base in the router table most of the time and has been real pain to use. It can stop in the middle of the job and no efforts can restart it. Then all of sudden it starts by itself. Somehimes it starts and stops periodically with a few seconds interval. But most of the time it works normally.
I replaced the switch in the base and cleaned sliding contacts on the base and the router many times but it did not helph.
It is in Bosch’s hands now but I am afraid the technician will not find the fault as it is very intermittent.

Never know it could be something as simple as a short in the power cord.

I would be very hesitant to continue to use a router having such problem if the technician isn’t able to positively locate and rectify the problem so that it can happen again.

me thinks that router would soon discover it should have been an airplane, as it flew outta my shop.

I have the boys in the field , keep broken or non working tools in their truck or trailer, just ticks, me off, when they say, oh we are short a saw, a drill today, have a broken one.
have a shop full of working tools, but they just seem to go stupid about replacing broken unit with a functional one, not only does it fubar the production, it can be dangerous for them if an electrical short or throwing sparks due to brush issue.
get rid of it, before you regret it

Its easy to discard somebody elses’ stuff. The router is $300 and it would be foolish to throw it out without trying to find what is wrong with it.

It does look like a loose contact somewhere but definitely not in the power cord. The LED light stays om when the router quits.

I agree, it can certainly be fixed, we live in enough of a disposable society today already! The question comes down to the technician’s ability to correctly diagnose and remedy the failure.

The big touted news about the release of that router (some years ago now) was that you could switch from standard to plunge base easily, yet still have a trigger on both bases. I looked at the design, and decided against that model, because I was sure the contact strip would fail soon enough.

It’s just a low voltage strip that has to make contact between the base and the motor. In my experience, tool companies like Bosch and Dewalt ask about 80% of the tool cost to do any major repair.

It makes me want to see dedicated plunge and dedicated fixed routers again. Some of those old designs worked for 30+ years without a glitch.

The fact that it comes on by itself tells me it has to be a switch problem despite the fact that you changed it. I would bypass the switch by connecting the leads to each other so it’s always ‘on’ and run the power to a second switch on the front of the table. Would be much more convenient that way. Reading it’s specs you would possibly end up losing the soft start function though unless that is controlled by a circuit board inside the router.

Just received it back. It is pretty amazing, i sent it on 6th and received on 11th so 5 days including two way shipping .
The repair notes say they replaced an electronic module. I am not sure which one. If the one in the handle of the base I am screwed. I already had teplacdd it wigh no success. We’ll see how ig goes.

If it craps out again and you can access the module it could have been a cracked solder joint. I once fixed an old TV that only had a dot in the middle of the screen by finding the vertical circuit and just touching each solder point with a soldering tip. On a TV that comes from hot/cold cycling. On a router it could be the same plus vibration.
