See picture attached. As you can see, there is an useless resistor, which is open, and a gray capacitor, 0.25uF/630V, which also suffered. I replaced the gray capacitor with the red one 0.22uF/630V. The resistor burned so bad that I had to make a hole to remove the burned area. The resistor value cannot be seen. I'm trying to guess what value it could be. I will try to draw an schematic to figure out its purpose. All I can see is that the capacitor and the resistor are in series. Any help in identifying the resistor is appreciated.

 

Appears to be an RC snubber!
Is it across the AC ?
I would hazard a guess at around 200ohm the C/R values depend alot on AC circuitry.
If wire wound, you may be able to measure from the break.
Max.

It certainly looks like a snubber for the 220 coil! Look at this fast sketch I just drew.

 

What size is the coil? Is this a contactor sized relay?
Also depends on how often the circuit is activated.

That's the relay in my first picture, at the bottom right.

 

If a snubber, seems rather large for a cube relay, although it is across coil also, but only the coil as a load?
Is this relay continuously operating many times/min?
Max.

I'm actually not sure. It's from a cutter that it's not mine. I haven't operated it. The board has other connections. I will try to gather more info.
