I've been dealing with fixing and making electronic projects for a few years now but my knowlege is still not perfect. I need help about this resistor. I just haven't ever seen this colour code on them before: Black, gold, silver, red and blue
Here is a picture.

This may be an inductor, not a resistor.
Inductance 0.62µH

Or, if it really IS a resistor: 0.62 ohms. 62 is the two significant figures from blue and red bands, silver band means multiply significant figures by 0.01, gold band means 5% tolerance; ignore the black band.

If it IS an inductor, as Harald mentioned, 0.62 μH is a quite small value. You may not be able to distinguish this component from a low-valued resistor.

I'm pretty sure it's a resistor because its marked as one on the pcb.

0.62 ohms might be hard to measure with a multi-meter. You could connect it to a constant-current source and measure the voltage drop to verify the resistance. No constant current source handy? Just wire it in series with a 100 ohm resistor and connect the series pair to a constant voltage source of about five to ten volts. Measure the voltage drop across the "0.62 ohm resistor" and use the voltage divider equation to determine the resistance.

I would've done that but the resistor is blown from the other side. I've just took a picture of it where you can see the colours clearly. I didn't know about that method. Thank you! :)
