Anyone know what type of resistor this is?

Looks like 0.2 ohm, 2 W, but it is hard to tell the physical size from your photo.

20 Ohm 250ppm, possibly wire wound but difficult to tell from the picture.

Agree, 20 ohm, maybe only 1 W. The latest generation wire-wound resistors have higher power ratings in smaller package sizes. How old is it?

It's a strange one, I have not seen a ppm marking on a 5 band resistor before, it's normally on 6 bands. Unless it is 6 bands and the burnt mark is hiding the 6th band? That means it will be a different value to what I first said.
Thanks

Yep you are right. Five band then.

I am guessing it is a 2W resistor, you could measure its size and see if you can find something close. See link to RS for a guide. You might find them on eBay or Amazon if you don't want to setup an RS account.

You can go lower than 250 ppm if you want to, it won't matter. Depends what's out there and pricing.

Here are some 1W resistors on Amazon.

Some 2W versions

Hope that component behind it isn't a charred MOV.

Put me in that 2W line also . . . . and almost entirely expecting it to be of a laser trimmed metal film composition.
If you were to take an ohmmeter scaled up to read 20 ohms . Touch the probes and short them out confirm your in circuit and contact resistance. Remember.
I'll just now bet that if you would now connect both resistor ends with a jumper and connect to one of the leads and take the other meter lead and hold it in firm and constant contact with the top aluminum band of a a single edge razor blade.
Then you gently drag to SLOWLY scrape away the paint and conformal coating at the BLACK center band of the resistor.
I suspicion that at one point that 10 ohms plus remembered resistance will magically appear.
Since you don't know WHAT caused this overload and typically is still being within the circuitry . . . if my HARRIER to fly . . . .I would be inserting in a 100 watt incandescent lamp . . . in place of . . .this resistor to see if it burns brilliantly------bad . . . . . . or . . . . .typically, being a bit more subdued in light output..
This, is being before I even attempted to test out with the new resistor, and even at that, in progressively longer mere seconds of plug in time.

That first band looks more brown than red. I then think that the gold band is a multiplier (0.1) which then makes the resistor 0.1Ω.
Still, I could be wrong.

 

Teddy as WHONOES thinks the first band might be brown, it may be worth you deciding on what colour you think it is before you buy and resistors.
