I have an Elna Star Series Supermatic ( 1971) sewing machine and its foot pedal gets really hot after few minutes working. I don't know if its normal or it is damaged. I dont remember exactly if it used to happen some years ago since I turned it on recently after some months tha was in its cover.
Hello,
Based on your description and since your sewing machine is older, the motor inside your machine is probably drawing more current to maintain the same output power and all that current is passing thru the foot operated switch.. What that means is that your motor windings may be breaking down from age and use or the contacts within the footswitch may be getting carbon on them from passing more current than the original design called for and becoming resistive ( which equates to it getting hot). I suggest you discontinue using it until you have it maintenanced to make sure you aren't risking a shock or fire hazard. Sight unseen, it's difficult to draw any other conclusion.
Regards,
Rick
If you are in the USA on 110 Volts then you can buy a replacement foot control from www.sewingpartsonline.com for your model Elna. It won't look the same and won't have the 2 speed switch probably though.
