My 3 month old machine keeps jamming up--it begins to run more slowly, with the engine straining, until it stops completely. The handwheel barely turns manually, when forced I can hear a loud clicking noise. The bobbin compartment is clean, there is no thread or fabric caught anywhere, and the machine is properly oiled. I've taken the housing apart completely and cannot determine any reason for this jamming--everything seems to be in its proper place. A few times the problem seems to have worked itself out, the machine began running smoothly again, but then it started straining to run again, and now I can't get it to budge. Has anyone ever heard of this?

So, the motor is straining to run the machine? Your machine is mechanical? Then, the old oil has most likely solidified and is preventing the machine parts from moving freely. Do not force the motor until you can get the issue addressed or you may burn out the motor. The following method has worked on several old Berninas that were seized:
cleaning out any machine is good , as most don't get \done get done to often , id be cautious on oiling a machine and only use a oil spec'd by the mfg. as some oils can soften and damage gears and such on some machines , oils should always be used sparingly and not left to drip down inside to points unknown , me id prefer to use caning wax for lubrication, as it never runs from where you put it like oils will
Is your White a mechanical machine (NOT computerized)? If so, it may need a good cleaning and oiling.
If your machine is a mechanical, be sure that you are cleaning and oiling on a regular basis. If not, the old oil turns to goo and sticks things together.
Use ONLY fresh good quality sewing machine oil (not 3-in-1, WD-40, cooking oil, or the old oil from grandma's sewing basket). Follow the instructions in the manual. If you want to do a thorough job, open the top and free arm cover. Slowly hand rotate the handwheel and apply 1-2 drops of oil every place that metal rubs on metal. Do NOT oil rubber, plastic parts, or belts. Don't forget the moving parts in the bobbin area and the needlebar since that's where you are having problems. Be sure to apply a drop on the shuttle race every time you begin a new project. Oiling according to the instruction manual should be done every 40 hours of sewing time. If in storage, oil every six months. I try to do a complete oiling of my machine (as explained above) every six months to keep it operating well.
To help loosen it up, you can direct hot air from a handheld hairdryer into the internal mechanics of the machine. Alternate the heat with oil until the machine is working smoothly again.
Is this a mechanical machine you're running on low speed? The usual motor doesn't have much torque at low speed (unlike the computerized machines with stepper or servo motors that have full needle force at any speed), and this can contribute to jamming.
Also check to make sure the bobbin case is in completely and not wobbly.
Set machine to wind the bobbin to check for how fast the machine will run. I believe it will run fast or slow according to how hard you depress the foot control. If it runs fast and slow you have a problem in the machine. Most likely the machine, if turned by hand, is hard to turn and it needs to be professionally serviced. before it is ruined. sewman7
This is a protection mechanism of the machine when it believes there is too much strain on the motor.
Check the hook race/bobbin area...for lint or thread jam....also check the couterweighted cam that drives the needle up & down, as ofter thread will catch and be wound around the shaft near the take up lever.....open the door on the Left (Face Plate) and where the shaft comes through the body is where to look, move the handwheel slowly and watch for threads....remove them gently by unwinding, be patient as they may be well jammed.........DO NOT pull and break them !!
If you are convinced there is nothing jammed & if all appears clear, there are 2 possible scenarios, and I am afraid you are not likely to be too pleased by either of them.........please don't shoot the messenger.
The DC motor is failing, or
The "A" board has problems.
Janome have a 5 year warantee on the Circuit board and will replace it if it fails within this period.
This is a complex and valuable machine and may need the services of a well qualified Janome Trained Service Technician, not just any old hack repairman.
Hi Gail4456...When you say "would not sew another stitch", do you mean that it is at a mechanical-stand-still? Or do you mean that the machine runs, but does not stitch?
Please update/correct me if I am misunderstanding your issue.
If your machine is 'frozen', remove your bobbin and needle. firmly grasp the balance wheel (handwheel on the right), and smoothly turn it clockwise until the jam is free, then use compressed air or brush or vaccuum to rid the now dislodged thread. Other possible causes for non-operation include: raised presser foot and/or un-depressed or faulty start/stop button.
If your machine is not producing stitches:
1) Replace your needle, ensuring the slotted side is facing towards you.
2) Wind a fresh bobbin, and ensure that you are threading properly through the bobbin tension spring.
3) Completely remove your spool of thread, and slowly rethread your machine ensuring that you don't miss any guides, and that your thread isn't becoming wrapped around the takeup lever accidentaly.
If you believe that you have a threading issue, do not retrace your thread. Instead, completely remove the spool and bobbin, and start again.
I hope this corrects your issue my friend.
