needs to know where to connect the blue wire bcuz in the old motor there was no blue colored wire but purple colored wire. Do i follow with the old connection wherrin purple wire was connected to a black wire? Thnx

Expert:  Tim H. replied 2 years ago.
Tell me which leads and colors were on the old motor and where they were connected and the same for new motor. Where was each lead connected?
Customer: replied 2 years ago.
dont know the name what I did was I took. pics before disconnecting them hoping to follow the same connection base on the color of the wire
Expert:  Tim H. replied 2 years ago.
If the new motor has one extra colored lead, it will probably be an "unused motor lead" and can be taped on the end and not used.
Customer: replied 2 years ago.
I did that on red wire but im the old motor there was a purple wire/lead and in the new one its blue, thnx
Expert:  Tim H. replied 2 years ago.
OK, this doesn't help me much, sorry. If the leads connect to a board and you already have a lead on the heat terminal and one on cool, then the blue is probably an extra "unused motor lead" and the end can be taped.
Customer: replied 2 years ago.
ok is it ok if i connect the blue lead from the motor to a black lead?
Customer: replied 2 years ago.
the black lead i refer to comes from bunch of leads that connects to the board
Expert:  Tim H. replied 2 years ago.
I'm sorry, I just can't help you given the vague information you have given me. Wiring a motor is something that needs to be done with certain knowledge and although we try to help do-it-yourselfers here as much as possible, I don't want to say that "yes, it's OK to connect these two wires together without much more information.
I will opt out and see if another expert can help. Please wait until another expert picks this up. Thanks!

thnx Tim
