Hardware Nintendo switch fan not work when on dock or charging.

[Dtwenty]

Hi. I have an issue with the Fan on my switch. When i use portable mode its work perfectly, but when its charging with the original charger or its in the dock the fan shot down. The strange is than its work with a low mAh charger.

I replace the M92T36 before because the console did not turn on and the USB C connector was replace after that but the switch it worked perfectly till few days ago.

This may be a M92T36 IC or BQ24193 IC issue?

Can somebody help me please.

I'm having the same issue. Already tried changing m92t36 and max 77620A with no positive results.
Where you able to fix this?

First check if the fan spins without the joycons connected, if that's the case there's a known issue where the right joycons makes a short thus stopping the fan. Some models have a diode that can be just taken off to avoid this issue, i recommend watching this video, time stamped the second where it get's taken out.

I had that issue with an old switch, a small plug inside was disconected, that solved it

i dont know, thats what i was told, the technician told me there is a small conector or something, so it could been something simplier so he could charge me.
