What to do when your Janome mechanical sewing machine won't turn on
A power supply failure, bad outlet cord or a failed On/Off switch can prevent the sewing machine from powering up.
Check the power supply first. Plug a lamp or other small appliance into the electrical outlet that you're using for the sewing machine to make sure the outlet works. If the electrical outlet is dead, reset the house circuit breaker for the outlet. If the outlet still doesn't work, try using a different outlet to power the sewing machine.
If the electrical outlet is okay, unplug the sewing machine and check the outlet cord for damage. Replace the cord if it's damaged.
If the outlet cord is okay, check the On/Off switch for continuity using a multimeter (with the sewing machine still unplugged). With the switch turned to the 'on' position, the meter should measure near 0 ohms of resistance through the On/Off switch. If the meter measures infinite resistance, replace the On/Off switch because it's preventing the sewing machine from getting power.
Common replacement parts for Janome mechanical sewing machines
- Bobbin. The bobbin is a small thread reel that holds the bottom thread in the bobbin case. The needle dips down into the bobbin case and loops the bobbin thread and needle thread to form a locked stitch.
- Drive belt. The drive belt spins the hand wheel and upper shaft as the motor runs to drive the sewing machine cams and gears.
- Foot pedal. The foot pedal sends power to the motor and controls the speed of the motor.
- Needle. Mounted on the needle bar, the needle pushes needle thread down through the fabric and into the bobbin case. Bobbin thread loops the needle thread to form a locked stitch. The needle moves up above the fabric and repeats the process to form the next locked stitch.
