As the title says, my fan runs at 100% even when it suppose to be idling.
Some background. My first smoke went great (everything worked as it should), but I realized that I had installed the 4 way switch backwards. I de-soldered it and did a second smoke. That's when I realized the fan was stuck at 100% all of the time. I have since replaced the four way switch, but am still having the same problem.
My digital multi-meter shows ~12 volts at the RJ45 connector between the ground and "blow" pins.
With the LCD up, IC4 (MCP1700) shows 5 v on the "top" pin, 3.3 v on the "left" pin and 0 v on the "right" pin.
Any ideas on how to further trouble shoot?
Would a picture be useful?
Thanks in advance for any help from this fine forum!
