Catherine50 Posted April 9, 2016 Report Share Posted April 9, 2016 I have a ten year old Millennium. I’ve just replaced the mother and daughter circuit boards, following the instructions to the letter. When it came to the part about turning it on and letting her run for a while in order to check the needle up/down function, I did that. The power comes on, but she won’t run, neither in manual or automatic. All I get is a very low hum. Help..... I’m feeling sick over this. Link to comment Share on other sites More sharing options...
Cagey Posted April 9, 2016 Report Share Posted April 9, 2016 Does the machine turn when the flywheel is moved with your finger? Also, did you oil all the oil wicks and let it sit for awhile to ensure the areas are all lubed up? That might get you up and running.

Catherine50 Posted April 9, 2016 Author Report Share Posted April 9, 2016 All of the wicks are oiled up. Turning the fly wheel doesn’t make any difference. Link to comment Share on other sites More sharing options...
barbm Posted April 9, 2016 Report Share Posted April 9, 2016 Do you have a speed set? The older machines won't run in manual mode until you move the speed needle up. Link to comment Share on other sites More sharing options...
Catherine50 Posted April 9, 2016 Author Report Share Posted April 9, 2016 Yes, I actually had the speed set right up to the maximum, and still nothing happened. Link to comment Share on other sites More sharing options...
Cagey Posted April 9, 2016 Report Share Posted April 9, 2016 When you spin the flywheel, do you see the motor shaft rotate also? If so have you tried moving the flywheel with the motor humming and see if it starts to move? If you have, I am out of any suggesting except to call APQS come Monday.

Mercedes Posted April 9, 2016 Report Share Posted April 9, 2016 Is it possible that one of the new boards may be bad? I would call APQS on Monday and see what they recommend. I had to replace a bran new board a few years ago and once I put another new one in, no problems. Link to comment Share on other sites More sharing options...
