A while back my front part cooling fan stopped working and I've been trying to figure out why. I can confirm the fan itself works from powering it separate, but when plugged into the FAN4 header on the printer, it doesn't spin and the D4 LED lights up. After testing the pins, I've found it's still pushing ~24VDC max, but only ~1-3mA where my PSU shows the fan pulling ~300mA@24VDC. I'm under the impression I need to replace my toolhead, but I'd rather replace a board component if possible.
