My Kenmore sewing machine is running very slow.

Enter question details


We've checked the belt which seems to be fine and oiled all the correct parts. Everything is working as usual but moving in very slow motion. The stitches look ok. Model 14810271 Serial 83453. Had the machine since the 70's - never had a problem.

Thank you for your answer. My husband cleaned and oiled the foot control and continued to oil the machine. It started working again and has continued working well. I appreciate your time and advice. Sorry it took so long for my reply but I was unable to sign in.

Thank you for your question on the sewing machine no speeding up when you press on the foot control.

I believe the model number is 148.12071 which would make it a 1970 or 1971 model.

If the machine will turn over easily with the hand-wheel by hand then I would think it would be either the motor or the foot control.

I would suggest removing the belt so you can see if the motor will spin up faster. If it will spin by itself without the belt connected then the machine is the problem with a dry bearing.

If it does not speed up then, it may be either the motor or the foot control.

The only way to truly check this is with a kwnown good foot control.

If you can turn the pulley on the motor freely then I would say that the foot controller is the problem.

This controller is not longer available from Sears but you should be able to get it on line.

The part number for the foot control is 6816 and if you Google that part number there should be a number of sewing parts dealers that will come up with a generic replacement.

You may even find a used one.

Foot controller 6816

Please let me know what you find out.
