Can a Tacsew get fix if the motor lock up?

Sorry, but gotta ask is it plugged in and turned on? Check before you answer. (I ask this because it happened to me, set up, ready to go, and no power. After an hour and the machine was in pieces, My son asked if i plugged it in and I snapped "YES, DUH" not seeing him twirling he plug in his hand...he informed me that you must be 10% smarter than anything you operate or eat....at which point he was happy to inform me, the machine was 11% smarter. If it is plugged in and turned on, is the plug to the foot pedal plugged all the way in? Is the machine on? If you get zero reaction, no movement or sound of any kind, the foot pedal my be faulty, it can happen. Take it back to the dealer and they should replace the entire machine or the foot pedal. Good luck and happy sewing.

try adjusting the foot pedal, there are jam nuts under the foot pedal
to make it go slower or faster.

This happened to me. I took apart the bobbin and there were no threads stuck. It moved freely, but the hand wheel was still stuck. So I checked the belt between the handwheel and the motor. I tugged on it (while the machine is off) and tugged on the belt to turn the handwheel. It took a couple tuggs to make the handwheel move, but once it started moving, it seemed to unfreeze. And I was back to normal. I can’t tell you what happened, but it’s fine now.

Not a solution, sorry but needing one too.
I've had this same problem, twice. The first time, a fuse was replaced and since it's under warranty, dealer paid for it.
Tomorrow I'll be picking it up for the second time, and this time I had to shell out $89!!
Does anyone know where that fuse is? Don't want to go spending more hard earned $$

Hi - The bobbin holder (on top) has two positions. Back (toward the wheel) and forward (toward the head). Try moving the bobbin holder forward. Moving it forward will cause the motor to engage. Good Luck.

Techsews are industrial sewing machines. Check out http://shop.raphaelsewing.com, especially their web blog. It's full of great information on Techsew machines.

If you can pull the needle bar down manually and it springs back up, the basting clutch is stuck. By someone who knows how, it's a very easy fix. I would guide you here, but I don't know how to explain it. Plus, you have to be very careful not to damage the spring loaded clutch.

When you tighten the belt it is a problem if it isn't adjusted right. You need to loosen the belt again. When you are pushing on the foot control the motor will begin to run. At the same time you can adjust the belt by carefully moving the motor. You will notice the motor speed will change as you do this. Stop adjusting the motor belt when you hear the motor speed at it's highest speed. Tighten down. Now, give it a try.

Generally going to have to be addressing the drive motor, either substituting a lower speed clutch motor for the existing one, ie if you have 3000 rpm motor, then going to a 1725 rpm motor. Alternatively, selling the clutch motor and buying a servo motor instead, which should be available with a variable maximum speed control. The Sewquiet 4000 can select different speed ranges with the flick of a switch. If you already have a servo motor and it does not have a variable max speed, then switching the drive pulley on the servo motor to a smaller size should help
A more convoluted solution would be building a support under the table for a layshaft with different pulley sizes so that the motor could drive one pulley and then a smaller pulley on the shaft would drive the sewing machine. Not a bolt on solution but pretty cheap to do if you are good at fabricating.
