The temperature won't rise when heating. (T22)

My cube3 always throws T22 error when printing, purging or changing filament for right side.

But when purging, it can extrude out normally by hand. So I think the temperature should rise correctly.

The left side is working perfectly, zero problem.

Is it possible that the temperature sensor of the right side is broken? If so, who knows how to fix or replace it?

Yeah there's the possibility. If you have a spare PSU (you should!!) try with it just in case voltages are dropping for whatever reason...

@bolsoncerrado Thanks for your reply.

I can buy one to test and as a spare part. Any suggestion about the PSU brand or model? Or just any 24V 5A ones?
