I hope that I can get this problem resolved. Can there be a thread started to help me through this? I will try to keep this as short as possible, I have a Ducane Mod. CMPB050C3A Nat. gas furnace. The problem is it will not fire up. I have gas coming to the main gas valve( Smart Valve SV9520H) According to manual test I get to glow plug (Hot surface igniter) does light for warm up, main valve opens, glow plug,(Hot surface igniter) lights then goes off, main burner should light (but doesn't) and should be sensed by the flame sensor but (no flame) .Can you help me with these three things in question? 1. Main valve (Smart Valve SV9520H), how to test?) 2. Flame sensor?, how to test? 3. Glow Plug,(Hot surface igniter) how to test. I can be reached ([email protected]) if you have any help for me ........ thnks BobO

Most often, it is misthreading. Remove all the threads from the machine. Then rethread each thread in the order specified and verify the thread path is correct for each. Also, when threading the tension mechanism, give each thread an extra little tug to make sure the thread is seated completely.

Oh yes, very IMPORTANT. Always raise the presser foot when threading the machine!!!

FWIW, when a thread breaks, trying to rethread that one thread will not resolve the issue because it is being threaded out of order. If rethreading the one thread doesn't work the first time, just bite the bullet and rethread every thread.

The other possibilities are the tension is too tight, poor quality thread, or a burr somewhere in the threading process of that thread is snagging the thread.

Is it possible the thread might be too old? If so, it might tend to break easier than normal. Also if it got wet.

Hello,
Try these solutions.

* Re-thread your machine as it may be threaded incorrectly.

* Raise your feed dogs If your machine has this feature.

* When you start to sew a seam, hold the upper and bobbin thread tails back and out of the way as you sew your first couple of stitches. This will keep them from getting caught in your machine.

I hope this helps.

Are you saying when you stitch, the bobbin thread lays on the fabric? Possibly the top thread is not seated in the tension disk. Here's something to try:

Remove the top thread from the machine.
ALWAYS RAISE the presser foot and rethread from the beginning.
Start with the upper tension set at the midway point. Tension is correct when top and bobbin threads meet in the middle of the fabric. Keep adjusting the top tension until the tension is where it should be. Tighter top tension should pull the bobbin thread up into the fabric.

If you are still having problems, would recommend taking it back to the technician. They do sometimes make mistakes so don't wait too long since the last service to bring it back.

Hi, possibly you have put the bobbin in upside down. Try flipping it over in the bobbincase and see what happens. It should turn clockwise when looking at the bobbin and pulling the thread.Check that your upper tension is not too loose. Check that it is threaded correctly.
Hope this helps.

Hello,
Here are a couple of things to try.

* Un-thread your machine and remove your bobbin. Clean any loose thread or lint out of your
bobbin case. Re-thread your machine, reinsert and re-thread your bobbin.

* Change your bobbin
There could be a nick along the edge of your bobbin spool that’s catching your thread as you
sew.

* When you start to sew a seam, grasp the upper and bobbin thread tails. Hold them back
and out of the way as you sew your first couple of stitches. This will keep them from getting
caught in your machine.

I hope this helps.

Here are some possible solutions:
1) Try a new bobbin, and if you wind your own, make sure it is wound very tightly
2) Take the bobbin case out and make sure there are no stray threads stuck down there, they can wreak havoc! To do this, unscrew your throat plate and lift the bobbin case out. Then use your lint brush that came with the machine, or another small soft brush and give it a thorough cleaning under there.
Hope these help!

It may be a result of extreme temperature changes from the time you tightened the shank until the time it broke however this is very unlikely.Typically the shank only needs to be tightened until it is stationary and immovable by normal operating stresses which is a very low torque value. As a general rule of thumb I use finger tight and an additional quarter turn. I once used epoxy and a short nipple to resolve the same issue but I had the advantage of having a pipe threading machine to fabricate the perfect size nipple and used a large washer and coupling to finish it off. If you try a new shank try tightening it as little as possible and I believe this will resolve the issue. Thanks for using Fix Ya and I hope this is of assistance to you.
