Replaced PCB Fan speed doesnt seem right


I had to replace my PCB due to it not kicking on the fan to circulate the air. I plugged everything back up the way it was before and it doesn't seem like the fan speed is correct. I know the black, red, and white wires control the fan speed. Is there a possibility the wires weren't plugged in the correct spots before? In the picture the black wire is disconnected because I was troubleshooting to see if the control board was the issue I had unplugged it to plug it directly into the safety switch to see if it would come one then. Which it did so I replaced PCB and it works now. Just doesn't seem like the speed is correct with AC running. Can I try switching wires around to see if it works? Any help would be appreciated.

Welcome to the forums.

Your picture didn't quite make it out of your computer.

You can swap wiring around. Make sure the neutral wire is connected properly and don't connect two speeds at the same time or the motor will burn up.
