Disconnect the line wire holding foot pedal from the terminal inside motor assembly.If your not qualified electrician don.t do this.Connect the two terminal wire that inside the machine where the motor mounted.This connection is supplying your motor in full speed,Declucth your machine from the handwheel so that the motor run only.Plug the machine and switcn but you must jug only if the motor run in couple second of course without the foot control this was disconnected already.So your foot control is defective vice versa if motor does not run without foot control motor is busted.
how to fix if foot contol is defective, in carbon type you must replcace the circular thick carbon.On Electronic control check the IC if this open or some capacitor and resistor are open,Replaced any pars that had been short circuited.If the motor is defective replaced the carbon brush mounted at two side of motor case,There is an opening port.The carbon brush has spring holding push this carbon brush to the brush armature of rotor.

What to do when foot pedal just stopped working on old Bernina 830


There are a few problems possible. Assuming that there is not a mains (house) power problem, use the following logic to sort out the problem:
1. Do you have a light (assuming that the light bulb is good)? continue to #2.
2. With the machine unthreaded, the presser foot up, and the power cable plugs fully plugged in at the motor and foot control, depress the control to the run position.
Carefully bend and wiggle the cables at the plug locations one at a time. If the motor runs, the cable wires are damaged so you will replace the cable.
3. If available, try a (known good foot control) from another Bernina 830 of that exact vintage.
If the test foot control runs the machine, replace your foot control. Note: If the foot control is a type 213 for very old models, suggest that the control be replaced with a two wire electronic phase type control. (requires the foot control plug end to be cut off and rewired to the new phase controller). These electronic phase controls can be purchased from EBAY. Stay away from the Bernina type 213 control if possible. The type 213 controls have not been available for many years and it is highly likely that these controls are in a used condition, so you will not know if it has been properly adjusted.
If the 830 is a later model machine with the type 232 or 290 foot control and it is determined to be defective, no problem as they can be repaired.
4. If the (known good foot control) still does not work, you can assume that the motor has a problem. Motors for the Bernina 830 are occasionally available on EBAY and other sources.
Note: If the motor brushes have worn out and the commutator has been damaged, the motor is also salvageable.
-------------
Note: Always unplug the machine from the mains power when not in use as per Bernina instructions.

Foot control does not work


Does it work by pushing the Start/Stop button. If so the problem is probably with the foot control. Make sure all connections are secure. You may need a new foot control. Contact your local Viking Dealer and try one of their foot controls to determine if it is indeed the foot control or something else. You can find your nearest authorized Viking Dealer from the Viking website - http://www.husqvarnaviking.com/us Click on Locate a Dealer for your local dealers.

Can't get foot pedal to work


Check foot control with a multimeter. It depends on the model if the foot control is standard 120 VAC or low voltage. This will determine how to test the foot control.

well if the foot pedal isn't working, you can either replace it with a new one or take the machine to a sewing machine repair shop & let them check the foot pedal & see if it's fixable

Took my foot pedal apart, now it wont work at all, just makes a clicking sound when trying to put my foot down on it..


Hello

Unplug the machine plug and wall plug on the sewing machine.

Check the power cord for cracks, burns, or faulty contacts as this could be a possible reason for the foot control not working.

Open the foot control by using a knife or flat surface tool, such as a flathead screwdriver, to pry open the corner of the foot control.

Check the wires to see if they are disconnected; this can happen if the foot control drops to the ground. To check wires, remove the circuit board using a flat knife. Inspect the wires inside the foot control. You will see some wires that are soldered together. Check to see if there are any broken wires, as this could be the problem. If the wire is broken, clean the area to remove any debris or dirt. Remove a small amount of the insulation before soldering. Solder wires together.

When you are done, reassemble the foot control and make sure it's working again.

I can't start to sew on my 830. The foot control is recognized(the start/stop button light goes off when I press the foot control), but does not make the presser foot come down. It worked 15 minutes ago...


If you lower the pressure foot before you press the foot control does it sew then? If so, then some how in your setting menu you auto pressure foot setting has gotten turned off.

What is err code F04


It most likely is your foot pedal. Unplug your foot pedal and start the machine without it. If it works properly without the foot pedal plugged in then your foot pedal needs repaired or replaced. This worked for us with the NX400 machine and I am sure the NX450 is closely similar. Don't bother to buy a Manual if you didn't already get one with the machine. A Service manual and parts manual is best; But just so you know they don't show the error codes unless you are a qualified and authorized repair person for the machines. I got my info from the repair man where my wife buys and repairs her machines. I am an electronic technician and mechanic so I understand how this system works. I will be repairing my wife's machines from now on.

My foot pedal doesn't seem to work when I push it down


Probably needs a new foot control. Bring the machine and the foot control to a shop, they can test it to see if it is the control, the wires from the control to the machine, or something else.

The control and wiring are sold separately, the control is often cheaper than the wires from the control to the machine, don't throw anything away until you have someone look at it first!

They will remove the non functional foot control from the wiring and put a new one on. A new foot control is not expensive.

Pfaff triptronic 2040 sewing machine


Could be a couple of things:
  1. Foot control is bad - take foot control to your local Pfaff dealer to try on one of their machines. If their machine won't run either, it's the foot control and you can look into repair/replacement.
  2. Machine has a short or some type or computer board problem - take machine to local Pfaff dealer and try with one of their known working foot controls. If the machine still doesn't work, your dealer will need to diagnose what is wrong.
Hope this helps.

Happy stitching,
