The thread cutter on my janome 7700 is stuck and clacking, then gives me an #4 error and locks up the machine can I fix it?
I have the 8200. It’s because of fluff/thread caught in the cogs that drive the thread cutter. If you slide off your accessory tray, take off your needle plate and from the rear of free arm section remove the 2 screws there (see photo) The plastic top cover will I click and lift/slide off (gently). If you look from the end under the metal plate you can see 2 plastic cogs (wish I’d taken a photo) - the smaller black one will be jammed with fluff or thread. I turned if gently with my screw driver and brushed and scrubbed with a pipe cleaner every time I turned it. Lots of fluff came out. Plugged it in and turned it on .. it worked as normal. Good luck.

Janome 6260 after running for about 1 hour will start to sew erratically, then stall with LO message. Will not wind bobbin when this message is displayed. Bobbins wind loosely and unevenly.
Here's Janome LO error;
LO: Replace the foot controller.
My first thought is if you're running nearly non-stop for an hour the motor is overheating. Not sure what the maintenance schedule is for this machine <?>. May need a good cleaning/lube. Then foot pedal, then other.
- Check for a tight or stuck clutch by the hand wheel.
- The machine may be jammed. Remove the timing belt to locate whether the bind is on the upper shaft or lower shaft. If it is the upper shaft, there may be thread caught in the take-up lever or crank pin. If the lower shaft is binding, check hook clearance, hook backlash. Check the lower shaft rear bushing for any black 'gunk'. If there is, replace the lower shaft and rear bushing.
- Clean the sensor on the DC motor and check if the shield plate on the motor is not loose or hitting the sensor. If either the sensor or shield plate is damaged, replace the motor.
- Check the upper shaft sensor. Make sure the shield plate is going perfectly thru the middle of the sensor. Replace the sensor and/or shield plate if damaged.
- If you still get the error, replace the DC Motor or upper shaft sensor (in this order).
