Help to identify the value of resistor

[Eldi4]

Did anyone know what is the value of this resistor, the color coding does'nt make any sense for me,  it was found on Delta Electronic DPS-220UB power supply, and the resistor is open-circuited.

Red-Red-Gold-Gold-Black?, what?

I had a similar situation before after a week of trying to figure it out it turned out that the black band was only there to indicate the end of the resistor.  So based on that I would guess its a 4 band resistor Red-Red-Gold-Gold and the last black band is only there to show where it ends.  I could be wrong though

 Well that is pretty reasonable,  so it was 2.2 Ohm probably,
 what is your resistor looked like, where is it placed?

Not that it looks anything like the ones I've used, but 5 band values include tolerance (not black though), and 6 band ones include tempco - 250ppm
But that ones does not look like a precision one .. can you measure it?

[Pete66]

I don't remember I think it may have been a CFL or LED circuit.   I do remember spending a while trying to figure it out and it turned out that the fifth black band meant it was a non inductive resistor.
So I treated it as a four band resistor and it worked out. 

You could try to find a forum where someone that has that same power supply and ask them to measure it for you.

I got bored and did a quick search on here and someone had the exact same question a couple of years ago.   
I think this will help you out.

Well, i think it's clear, thank you very much

Note the comments about it being fusible - any resistor that measures open circuit, with so little apparent damage, is almost certainly a fusible type. Replace with the same for continued safety.

You also need to find out why it fused, otherwise the new one will almost certainly suffer the same fate.

Red, red, gold, and gold is 2.2 ohms and 5%.  I assume the black band indicates a special feature like fusible or flame proof.
