| + | [* black] Unscrew the inverter board (the one with a 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 switch high voltages, and large currents, at a rapid rate, so they are subject to wear and tear. The 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). |
