Sewing Machine: Won't turn on
Check the electrical outlet for power and reset the house circuit breaker if the outlet is dead. Replace the outlet cord if it's worn or damaged. Unplug the sewing machine and check for loose wires. Replace the on/off switch if it's defective.
These repairs may help solve your Sewing Machine problem:
Replace the sewing machine On/Off switch
The On/Off switch turns on the work light and sends power to the foot pedal. Unplug the sewing machine and check the On/Off switch wiring if the light switch doesn't work. Replace the on/off switch if it's defective.
Replace the sewing machine outlet cord
The outlet cord attaches to the On/Off switch to provide power to the sewing machine. Examine the outlet cord regularly for damage. Broken wires in the outlet cord prevent the sewing machine from getting power. Replace the outlet cord if it's damaged or broken.
