Janome Sewing machine - spring fell off

Please help!My 2 year old son took it off and I cannot get the thing back on.It is in the little door on the left side. I see where it came from. Also, does this have anything to do with the thread getting too tight in the thread tension ( the step where you wind it down into the machine front). I have never been able to get past this problem. Help!!! It is the Janome 4618 le model.

Re: Janome Sewing machine - spring fell off

I had to take it in to get fixed because I needed it for my Christmas sewing projects. The owner tried jacking up the price on everything. I am not bringing it back there anymore.
I'll post back when the dumb machine conls out again!

Re: Janome Sewing machine - spring fell off

Can you post a photo of this so we can ident the actual spring and etc, if it is the check spring, it certainly will affect thread tension.

Post to here or via and I'll see what we can do to help if it is not too late so many months after the original plea.

How to unassemble and clean Janome sewing machine foot controller model 21371?

There are 4 screws on the bottom, 2 are under a rubber pad that can just as well be discarded. Be careful opening the 2 halves of the case, since the assembly is spring loaded. Note carefully the position of the wire bail as you open.
Your control is failing because the two resistive strips are dirty. Blow all the lint out the the case, and swab the two resistor strips with alcohol. Move the wiper arm so you can reach both ends of the strips.
To re-assemble, lay the bottom half on the table and place the plunger and wire bail in position. Then set the large ends of the springs over the round plastic projections in the plunger. Take the top half of the case (with all electrical parts) and engage the bottom end (away from the springs). Before pushing the top half closed, be sure that the small ends of the two springs fit around two screw heads.

My two year old son just pulled the spring off that makes the arm swing to do zig zag....I can't figure out where to hook it back on. Nothing, including the spring, looks to be damaged.

Call your local Janome dealer and ask if someone can look at the machine while you wait.

When my children were little I kept the sewing machine closed and sewed while they napped.

Janome SD-2014 sewing machine dogs fails to operate in reverse

The grease has hardened and that is what makes it not work. You need to remove the spring and clean all the old grease off it. You can put new grease on if you want but it isn't necessary. The machine should be lubricated with a good quality sewing machine oil(not 3 in 1). You need to oil any place that moves and rubs, This includes the ends of each shaft, the needle bar and the cinnecting links that drive the needle bar. Nothing is permanently lubricated.. you'll find this machine will run much smoother and quieter with fresh lubrication.As a matter of fact, if you use the machine a lot, it should be lubricated once a year and never less thanonce every 5 years.
One more thing. If it is on the main shaft that it has hardened you can spray it with a mixture of fantastic, water and some ammonia. Free it up and give it a light shot of oil.

Download a Janome (Jem 639) sewing machine manual

Just today  i got out my little janome i bought years ago and it is this model.  There was no "manual" with the machine.  All that came with it is a large 20X14 two sided print out.  I can scan and send this to you with an email address.

Top tread bird nesting.

When you say top thread nesting, I supose you mean that the thread is messed up at the top of the needle plate.
If so,
1st, either your bobbin thread is completely loose, or the bobbin thread is not held under the bobbin case spring,
or lint has been accumulated under the bobbin case spring.
2nd, the top thread is very tight,

or both.

Janome 9000

I have a Janome 9000, was sewing and broke needle, replaced and broke another. I didn't have machine threaded, took out bobbin and would sew a little and stop saying thread broke. I took off top plate and started machine again, sew a little and stop saying thread broke. So I took out bobbin case and sewed again and stopped repeating the message. Everything looks OK, bobbin case and top plate. I guess I want to know if the timing could be off or do you think it is the computer part of the machine...Should I take it to the Sewing Machine Shop??
