Roomba 400 Series Disassembly and U2/U4 Charging Fix
Thanks, I'll try anyway. Still waiting for the mosfets from aliexpress
Hi, does the parts from Aliexpress fix the charging problem? ThanksNguyen - trongdong79
Didnt work for me unfortunately, but feel free to try for yourself - ZahavaA
Where exactly are the both mosfets located
My roomba would not charge, it would slowly blink red while charging and then green after many hours. I unplug and try to turn on and get nothing. Plug it back it and get the same slow red pulse as if i never chargwd it. Anyway, i did exactly as this post said and i also took the advice of jasontaylor71 and upgraded both mosfets. You dont have to completly remove the board. Just enough to get at the 2 mosfets. Reassembled and it works perfectly. I almost threw my roomba in the trash but tried this fix for $7(ordered 3 just in case). Fun little project. THANKS!
