My name is Darcy from Sask. Canada. I am an independant self employed person who does repairs to sewing machines here.  Currently working on a Viking/Husqvarna #1 computerized sewing machjne and am experiencing a wierd issue with it. It seems like it may be a foot control problem from what I can tell. It seems I have to turn machine on for a while (2 to 5 minutes) before the foot control properly controls the speed and or startup, and sometimes that is a hit and miss. The when it has been on for a while, it seems to work perfectly. Other times not so much. The foot control on this unit is the original large square platform and has a retractable cord. I have taken that whole assembly apart, cleaned the contact plate washers on the cord retractor portion, as well as taken the actual electronic switch apart and cleaned the contacts on it. This also seemed to help off the get-go but then I turned the machine off for an hour and back on and the same problems. Sometimes if I quickly engage the foot control switch, it works. But if I start slow and gradually depress to faster it does not respond and if I do tune to hold it down it seems to gradually increase in speed by a step at a time every 5 seconds or so until it reaches full speed.  Any thoughts on this? I am thinking it is just that little contact module inside the switch that is maybe causing the issue. Do you think I could try a generic electronic foot controller on this? Thanks,  Darcy

Because you say all was working for a while before this latest event, it will be the supressor that has failed, they are generally in the foot control (some machines have them in the main body near the power inlet) and it needs to be removed, it only stops interference to Radio & TV and is not necessary for correct function...............your nose will tell you if it is in foot pedal or inside the machine..

Unplug from mains, undo cover/s and find the electronic looking item which is cracked, burnt & probably oozing brown goo and smelling like burned plastic only worse.... Simply remove this from the circuit, clean the region with some denatured spirit, methanol or similar, wait until completely dry and re-assemble....this should fix the problem of the machine "running on" by itself....as to whether you have done a good job of the initial electrical repair, only you will know that.

By the way, how's the dog ? Guess the machine was not plugged in at the time !!

Same problem with my 400. I took it in to dealer and they said main computer board on my machine would have to be replaced. Fortunately, they agreed to get it fixed for me. My machine is 2 years old. How old is yours? I wonder if this could be a manufacturer defect on the machine? Maybe this needs to be addressed with Viking Husqvarna Corporate.

Yes it does sound like a faulty foot control. The power cord is probably fine, you just need the controller. Ebay is a good source for parts.
