The foot pedal for this machine keeps getting stuck which makes the machines motor struggle and churn instead of stopping, when you lift your foot off

It is likely your foot pedal controls are stuck. Either they need repaired or you need to make an investment in another foot control.

foot pedal is stuck

Sounds like your motor is going out. Engage your bobbin winder, and make sure the needle isn't moving. Push the foot pedal all the way down and listen to the motor. It should be a steady sound. If it sounds like it's struggling, your motor is going bad. Your foot pedal can also be an issue.

Is the foot pedal not returning to the off position? Try disconnecting the foot pedal. If the machine stops running, then your problem is in the foot pedal. If it keeps running, then your control board is bad.

I suggest having the machine checked at a sewing machine shop
to see if there is something wrong with the motor, or the foot pedal
but first check to make sure the power cord & foot pedal are
connected correctly

only having the machine check at a sewing machine repair shop can say for sure

It sounds like the food pedal is sticking. I have had this happen only to find that the pedal had drifted under my mobile thread drawer and was unable to lift up when I took my foot off it - yikes - looked like a ghost was operating my machine! However, it you are sure the foot pedal is not stuck under a piece of furniture, perhaps the spring inside is not decompressing completely. It needs to be checked. I am not that familiar with the Emerlad models - do they have a Stop/Start button on the machine itself? If yes, perhaps this button is stuck in a little? Check that also.

does the foot pedal plug into the machine by itself? if so unplug the foot pedal & then turn on the machine, if it doesn't run by it's self then you know it's the foot pedal.
but if it still has the problem check the foot pedal for a circuit board

If you have a start/stop button, yes you can use that instead of a foot pedal. Most viking designer models use a common foot pedal, so you might be able to find a used one.

there is something stuck in the pedal causing the electric circuit to connect, perhaps some thread or a pin.
unplug it from the machine and see if you can unloose it from under the panel.
