+[title] Take out the inverter
+[* black] Unscrew the inverter board with heat sink in order to access the IGBTs.
+[* black] There are two IGBTs (Insulated Gate Bipolar Transistor) on this board that are likely to fail. These electronic components are supposed to switch high voltages, and large currents, at a rapid rate, so they are subject to wear and tear. These IGBTs are bolted to a hefty heat sink.
+[* red] This picture shows the inverter board with heat sink.
+[* green] There are 3 components attached to the heatsink: a bridge cell on the left, an [link|https://toshiba.semicon-storage.com/info/docget.jsp?did=16729&prodName=GT60N321|IGBT GT60N321|new_window=true] in the middle and another type of IGBT ([link|https://datasheetspdf.com/pdf-file/86037/ToshibaSemiconductor/GT30J322/1|GT30J322|new_window=true]) on the right (not visible in the photo).
