Feed dog won't feed fabric singer touch and see 756

Not knowing this exact model or your history with this specific machine, I'll just toss out the following info.

If feeder dogs are not stepping, none of the following applies to your problem. Otherwise;

I believe the 1425 does not have dog up/down selection, therefor it uses stitch length zero (or about) to keep the feeder dogs below the needle plate when embroidery/darning.

Assuming feed dogs are stepping (rotary reciprocation), adjust stitch length toward a longer setting. Eventually this should raise the height of the feed dog step to a point above the needle plate thereby feeding the fabric.

So if choosing a longer stitch length feeds fabric, either the feed dog height needs adjusted, or something else has caused feed dogs to be lower than normal (additional repairs).

The feed dogs do not drop on your machine. Instead, your machine uses a feed cover plate that is placed over the top of the feed dogs to protect the fabric from contact with the feed dogs. It is part #11 on page 14 of the manual

..

Confirm the feed dogs are raised. Make sure the feed dog teeth, area under the needle plate and the bobbin area are clean of any debris, thread, or buildup. Some machines also have a presser foot pressure adjustment that increases the pressure the presser foot applies to the feed dogs. The feed dogs could be worn (never run the sewing machine without fabric between the presser foot & feed dogs).

Or, the machine has not had a thorough cleaning and oiling recently and the feed dogs are sticking from old oil.

Wheel on right side that controls the needle up and down is very tight...

Without fabric in your machine and with the presser foot raised, do the feed dogs move front->back? Are the feed dogs in the raised position? Is the stitch length at a 10-12 stitch per inch setting so that the fabric actually moves (try increasing the stitch length to see if it makes a difference)?

Does your machine have a presser foot pressure adjustment? If you are sewing light weight fabric, the pressure may need to increased so there is more pressure applied by the presser foot to the feed dogs. You can also try adding a strip of tear-away or wash-away stabilizer to the underside of the fabric as you stitch so the feed dogs have something to grip.

Are the tips of the feed dogs rounded? Could be worn and need replacement.

If the feed dogs are not moving, how long has it been since the machine was cleaned and oiled?

It was working now it seems to be frozen the needle part wont move

If the feed dogs remain below the needle plate, and the feed dog lever does not activate them, then perhaps something is disconnected in the feed dog mechanism. The feed dogs should rise when stitching begins.

...

I don't know this machine but in most machines the feed dogs are normally lowered from a switch beside the bobbin case behind the door of the bobbin case.

It sounds like the height of your feed dogs is the problem. I don't know which model you have, but of it's a plastic casing, you will need to take it in for service.

Are you sure the feed dogs have not been accidently lowered? They will still move when lowered but not feed the fabric.

Here is a link to page 22 of the manual. It shows you where to flip the lever to raise the feed dogs. If your feed dogs are not grabbing fabric your feed dogs are lowered.

if the fabric won't move then there is something wrong with the
feed dogs, check in the needle plate to see if you can see the feed
dogs. you should be able to see them & touch them with your finger
since they are not moving the fabric it would be a good idea to
have the machine checked
I'm putting a link for a free manual for the machine, you can check
in the manual to see if it show where the feed dog lever is on the
machine, if it doesn't show a lever, or the lever is not responding to
movement then the machine needs to be checked to see what's
wrong.

h! there,
fabric moves forward when machine run due to movement of feed dogs,feed dog has a teeth, when your foot presser goes down attached to fabrics the pressure hold the fabric between pressure foot and feed dogs that why when machine run feed dogs pushed fabric when recieved stitch.try to check adjustment of feed dogs it maybe set at rest or neutral.reset it to upward towards needle.check also bobbins thread if accumulation was build up under feed dogs.regard and have a nice day.
