Hello there, new to forum and power tool repair in general too.
Was sanding with a bosch gex orbital sander and managed to completely fill the filter that attaches, motor revved a bit and then stopped working. Realized i had totally jammed up the filter and likely overheated the motor a bit. I cleaned it out and it ran for a few seconds then would slowly power down. I took the whole thing apart, don't see any melting or burn on the armature, the brushes seem a little chipped but not bad, there's still power getting to the motor as when i give it a solid tap with the cover off you can see it starting to spin a little. Is this a brush issue? new armature. any suggestions really appreciated, I've got a whole kitchen to finish and really don't want to fork out for a new sander.
