Introduction |
| Different reasons leading to the PWM T1 or T2 failure, here is a guide to replace the transistor. | | This guide is a fast-guide for makers. No transistor or electronics knowledge needed, hence the job can be done very quickly if parts are available. This can save you in the area of $100-$150 for replacing the whole mainboard. | | The issue is discussed in the following forumsaddressed here: | | | [https://ultimaker.com/en/community/11366-cooling-fan-always-on-umo-update-now-voltage-its-0|https://ultimaker.com/en/community/11366-cooling-fan-always-on-umo-update-now-voltage-its-0] | | | The mainboard schematics are stored here: | | | [https://github.com/Ultimaker/Ultimaker-Original-Plus/tree/master/1091_Main_board_v2.1.1_(x1)|https://github.com/Ultimaker/Ultimaker-Original-Plus/tree/master/1091_Main_board_v2.1.1_(x1)] |
