Question about Bernina Bernette 75
While sewing my machine seized up. The motor grinds and machine doesn't move. Hand wheel is tight and barely moved when manually turned. I have cleaned and oiled machine.
Please don't use WD40 on your sewing machine, WD40 is an alcohol based cleaner and will do the opposite of lubricate. Take your machine to a certified Bernina Repair shop, they will have a look at the timing and lubricate all of your gears. Lubricant will dry out over time, grease turns to putty and oils turn to varnish after several years of non-service. Lint is attracted to moisture, moisture being those key areas of any machine. Lint acts like an oil wick and will draw out your lubricant from key areas. It then begins to attract dust and other nasty things over the years to become grit. Your motor begins to burn out due to stress trying to move all of these clocked gears, cams and shafts. Take your machine in!

Be sure to oil your serger frequently as directed in your manual (use SERGER oil--Bernina sells it). A serger sews so much faster than a sewing machine therefore needs oil AND cleaning more frequently. If you notice that it is sounding a bit noisy, clanky, or the motor sounds like it is straining, there's a good chance it needs a thorough oiling by your Bernina technician.
