Same problem here. But mine is a little different.
Last night I just finished setting everything up. extruder calibration, steppers calibration, PID tuning for both Bed and head, and started printing. After a while, I got a thermal runaway alert and the printer... Didn't stop. The head temp kept on rising, and I had to trun it off after 285C. When I tried to power it back on, the head temp keept on rising. I quit and left it overnight. Now, after trying again, the head dosen't heat but the bed is always on and heats by himself.
If you don't dare solder a mosfet, you can use an external Mofset and switch it with the pin that went to the original mofset.

I ordered a new board, the mosfet was ok, the gate cip was fried.
Hi Github community,
After fixing the short in the board with the TH0 terminal by swapping terminals THO and TH1 around in Marlin, I am now experience an issue with my hot end instantly hitting up as soon as I switch the power on.
I have been doing some reading and this can happen if the thermistor is short or the heat cartridge is dead but I also saw that this could be because of the Mosfet's shorting as well.
How do you go about testing Mosfet's for shorts? I have tested the voltage output for terminals for HB1 and HB0 respectively and neither is outputting 12V when I turn on the machine so I assume the issue is at the hot-end.
Am I testing the Mosfet's correctly and if they are short, does anyone know where to get replacements for the skr 1.4 turbo board?
Thanks
