My KSGER T12 Soldering Station developed a fault! I picked the iron up half way through soldering a project and it went bang! I opened the handle to find the red wire in the handle had disconnected from the solder lug and shorter on something else! From then on, all the screen showed was ERROR and B1 and the iron heated in an uncontrolled manner.
A quick Google found me the schematic, and reading how the device was supposed to work, I guessed the PMOS FET Q1 (TPC8107) had failed short circuit source to drain. This, the STM32F103 MCU was unable to read the temperature of the tip to know what to do.
Swapping out the TPC8107 fixed the issue, and soldering the red wire back and adding some better strain relief has my T12 iron working again!
