I got a C4 error. It will turn on, but not sew
I recently got a C4 error on my machine. It turns on, but when I try to sew, it doesn’t work and instead gives me a beeping C4 error. Before I got the error the tension felt tight. I didn’t find many YouTube videos that related to this issue, any that were helpful. I took it to a repairman but he said the circuit board was bad. I don’t think he was right, because he then tried to sell me another machine. I know I might have to replace it, but I still want to know if it’s truly a circuit board issue.
