Same fault, a dead (cheapo) relay. Small transformer labeled SD41-501 but looks like yours, I guess it's the same one just with a different label.

Great article! And very relatable...

I'm also new here, and have a dismembered AFK BM2N on my table. My issue is slightly different. After replacing the drive belt, which had fallen apart, which often happens on these machines, i gather. The motor failed to work. Now when my wife reported the issue to me, the motor was trying to turn. However, the old string-based drive belt knotted up and the motor could not turn.

No burning smell, no black on the motor, so I am guessing a fuse has gone somewhere. The heating element still works fine.

I am a real newb when it comes to electronic circuitry I'm afraid, but I'm so invested in this project now, I want to complete it! Do you have tips for me? I have a soldering iron and a multimeter, but am rather bad with both...

Thanks! Best regards, Mike.

I'm new to this blog and just found this detailed report.

Thank you for sharing.

I would like to ask your advice for the following problem on the same machine:

I changed the belt, then plugged the circuit before mounting everything back, pressed the ON button and It started working ok, but instead of pressing the ON/OFF button to end the program, I unplugged the circuit.

Now, I tried plugging again, and without pressing ant button,the motor runs continiously,the heater element is on, but neither the display or buttons work.

What could have happened?

Could hoy please help me finding a solution?

Best regards

Although you probably need at best an adjustable adapter voltage for that. So you can find the relay switch-on level coilvoltage and a minimum voltage level at which the relay still holds its magnetic on switch position but just barely. Immediately below that level the relay switches off and can't be switched on with a voltage that is just a bit higher than the switch-off voltage was. Only until the a lot higher switch-on voltage is reached again. This effect is often known as hysteresis. Like also is the effect that is known in magnetic heads of VCR's. Or just measure the coilvoltage over the always needed coil transistor protectiondiode. The wire of the defect relay coil is now ideal for repairing small defects on small copper tracks of smartphones and other defect devices. So will still come to good use again. Have a splended day too!

This is an informative repair article,I learnt some knowledge from it. Usually I test relay with external power adapter,once I know the coil voltage which is usually inscribe on the case.Have a nice day.
