Your sewing machine is an amazing creative appliance that operates on standard household electricity. To control the machine it uses a pedal. You can control your sewing machine by pressing down on the foot pedal with your foot. The harder you push, the faster the sewing machine runs.
The pedal on a flower is what makes the flower beautiful. In similar fashion, Your foot pedal on a sewing machine gives power to the sewing machine so it can make things beautiful.
The sewing machine foot pedal may be a resistance device, an electronic device, or a air pressure device. Each one works differently. Associated problems are specific to the type of device.
The most common type of foot pedals are resistance based devices. These use a resistance core often made of Bakelite, levers, and electrical contacts. Problems with resistance devices include general wear; cracks in the resistance core; broken springs, levers, or other mechanical parts; and bad electrical connections.
An electronic pedal uses a circuit board with resistors, capacitors, and integrated circuits to control the flow of electricity to the sewing machine. Failures of these foot controls result from electrical surges, shorts, and general degradation of the electrical components. Problems with connective cords can also be problems.
Some sewing machines use pressure sensitive switches in combination with electronics and an air ballast foot control to control the flow of electricity. Potential problems include ballast leaks, electronic failures, and electrical contacts.
When you have a problem with your pedal, the first issue is to diagnose the source of the problem. Some of the obvious things to check include the flow of electricity, electrical connections, and on off switch issues.
Here are some tips on how to repair a pedal.
Begin by identifying the source of the problem. Check out the foot pedal to determine its type and inspect it for the most obvious signs of fault.
Listen to your foot control. When you shake it, do your hear any rattle? When you press down, do you hear any strange sounds like crackling or popping?
When you service a sewing machine, one of the primary diagnostic tools at your disposal is listening. Hum, buzz, crackle, rattle, and pop are bad sounds that indicated broken or worn parts inside the pedal. Failure of the sewing machine to operate can be an indication of electrical breakdown.
The back of resistance foot pedal usually slide off giving you access. Some resistance and electronic foot pedals have screws to remove in order to access the insides of the foot control.
Now you need a tester. There are a few different types that will work. A TVOM, Continuity Tester, Circuit Tester, or Resistance Testeris now needed. Set the tester to test Resistance in Ohms. Place one probe on one wire going to the sewing machine pedal. Place the other probe on the other wire going to my sewing machine pedal. When I press down on the sewing machine pedal, what happens on the meter?
If there is no needle action, I have a broken circuit either in my wire or in my sewing machine pedal.
Double check the power cord and cord leading to the foot control. Any cracks or faulty contacts can make the foot control fail. The electrical contacts inside the pedal are also critical.
Use of your meter results and visual inspection should identify most apparent problems. Minor repairs can be made to most foot controls, but often it is advisable to replace the foot control. - 15254
