Hello everyone,
First off, sorry if this is the wrong section to post this.
I'm trying to troubleshoot these boards that control blower motors.
Two of them power the motor fine, but doesn't kick it into high speed; the other one I found a thermistor (SCK 203) blown and arc against a relay and a fuse blown. Replaced all three components with used ones and the fuse blown again. Looking for help trying to figure out what's wrong. Images attached of the board with bad fuse.
Thanks,
Mark
