Bypasisng a s3m semiconductor?

Question for anyone that knows I have a control board that powers a magnetic vibrating motor used for weighing grains. Current motor is a cheap made in china motor so I purchased a Syntron Magnetic Feeder Model F-T01A motor to replace it. Both motoar are 110v so I though this would work but when I
hooked up the new motor I'm getting no power to it. On the control board it seems the new motor may have severed a s3m semiconductor that jumps a connection on the circuit board that would feed it the 110v, so my question is can I remove this s3m semiconductor and just soldier a bridge bypassing it? Do not know anything about circuit boards and what this s3m semiconductor purpose is so any help would be great.

no

S3M = 3.0A General Purpose Rectifier

Ok another question seems this is an output and maybe the china motor has this amp restriction is very small and does not compare to the new motor which is a much more heavy duty motor SO could it be removed in this case, since new motor can handle more? If not what would happen if I removed it anyways to see? Can I increase the it to something larger?

I need this board to control this new motor somehow so if you know of another way please let me know.

It would be good to obtain a schematic for that control board to understand what the 3A diode does. Few people who manufacture and seek a profit place components on a board that are unnecessary. If your motor is more powerful you may need a "more powerful" diode to do the job of the SM3 that may just have been destroyed by the more powerful motor.

Seen from the point of view of trying to be logical. If I have a 100mA fuse and 1Amp circuit, and the 100mA fuse keeps blowing, do you think I should use a smaller fuse or no fuse at all to solve the problem?

Perhaps more fruitful to compare the board capability to the motor, rather than the motor power to what you want the board to be able to do. Facts make circuits work, not speculating without consulting real capability.

Try to get hold of the control board specs/user manual, and the schematic if that's in any way possible (maybe not), that will help to decide if a larger diode will solve the problem, or if you may need to re-think using the motor and control board together, and may want to look for a workaround solution to find compatibility.

Thanks d123 the new motoris a Syntron Model F-T01A

Specs on it are: 115 V 60 cycle @ .9 amps

I would have thought .9 amps would be fine?

The start-up and turn-off motor current will be quite higher than 0.9A, if you have a DVM with an ammeter, try on the 10A setting to have a look - or hopefully it may be defined in the motor specifications.

Maybe (or not) the diode is a flyback diode to protect the rest of the circuit from that current and at turn-off shunt it safely to ground instead of flying back into the rest of the circuit. Please bear in mind that I am assuming the start-up current wouldn't exceed a 10A meter's capability, so caution is always better than misplaced trust/ a carefree attitude.

Check the actual motor peak current if you can, and you could try to size the replacement diode accordingly, perhaps rated for double the peak current of the motor would be a safe bet.
