Just to share how to fix Noxxa Multifunction Pressure Cooker no power issue.
Next, power it up and check is there any output before (AC) and after the bridge (DC)? YES.
Regulator (7805) output? NO! Found it. Input is about 14V but no output

Desolder it out an do a quick test by it an 12v input
No output at all, compare with the new one
