Why is my sewing machine pedal stiff?
This can be an issue with the belt on the machine that is broken, a piece could be jammed or the motor can be broken. The only thing you can actually do now is to open the case of the machine and check the belts on the machine. Try turning the wheel on the machine and see if the parts on the inside are moving at all.
Why is my sewing machine not starting?
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.
