I HAVE MOTOR CONTROLLER MC2100-18W WITH C31 BURNED UP DOES
ANYONE HAVE THE VALUE OF C31 AND A CLOSE UP DIAGRAM OF THE PRINT.

There is a reverse engineered version of the MC2100 here if you do a search.
I may have a 18W ver here, if so will post the value.

Can you take a pic of the boards showing the C31 location?

 

Hi, I have the same issue here. C31 was burnt and causing a short on the board. I have removed it and it is no longer short. When powered on without C31 on the board the led blinks 8 times. Does anyone know if replacing c31 will solve this? If so does anyone know the value of c31? I'm thinking 10uf but unsure of v.
Thanks in advance.

 

The model I have which has a C31 is on a version that uses a SMPS for the 12vdc.
C31 has 2229 on it where tha value normally is, not sure of what the 9 signifies.
It appears to be a ceramic or even a Tantalum.
As a last resort, you could add a normal linear supply as most of the other model versions do.

Thank you for the info! Very much appreciated

Would it be possible for you to post a picture of it?

 

Of what? the component C31.
If you want to confirm it the same component, you could do it?

 

Please, if possible. I just want to confirm I have the same board.

 

This is the board I am working on the blue/green dot is the location of C31
I am thinking of replacing it with a 10uf 16v tantalium capacitor but I am not sure about it

 

Pic of cap imediatly above the switching transf.

 

Yours is a totally different board.

 

thanks for your time! I'll update here if I get it sorted.
