My England 25-PDVC room air blower has a red and black lead that connect to two red leads from the circuit board. During a good clean the tape I had to mark which red wire from the circuit board went to the black lead on the blower. Does it matter which wires connect to which? If yes how do I tell which red wire goes to the black wire on the blower? Thanks for any help. By the way if you have never taken the room air blower out and cleaned it you might want to. Mine was so full of dust you could not see the fan blades in the hamster wheel.
