My Robomow quit working last week, I was out of the country on a job.
So when I came home I found a bunch of extra growth and a mower complaining that the main power had been cut. Sure enough, the AC adapter & mow control box plugged into the wall was dead. No lights, no activity, nothing.
A replacement was located for $180, but I decided to take a crack at fixing the old one.
I took apart the charger box and found nothing wrong with the low voltage board within. The box also contained an ordinary “laptop brick” AC/DC converter. I decided to open that as well. Fortunately for me it was pretty obvious- a small burn mark on the PCB right at the hot pin for the AC input connector. No continuity from the connector to the board. I cleaned it up and applied a little dab of fresh solder, and that was all it took.
Mower back in service minutes later and I got hand the money to my wife so she could replace other things that broke while I was gone. At least that part doesn’t change.
