Ey I don't post often but I ran into problem identifying burned resistor. I don't know what to do it's shorted and I need a replacement.

Can you scrounge up a schematic of the whole circuit online? With the right search, you'd be surprised what you can find schematics for.
>>933359
Start by posting a much better picture.
No schematics I checked and emailed. No luck.
Corner band is red. One over pink or orange. And far corner is gold I think.
1 more band.
Red orange and gold?

Are you the guy with the broken refrigerator?

Red Orange Gold = 2.3 ohm
Red Violet Gold = 2.7 ohm

Check any other components in the same current path as the burnt resistor, its probably a current sense resistor so there could be something else shorted on the board and the resistor has acted like a fuse.
>Tips on a better resistor?
Get one rated for a slightly higher wattage (space permitting) and make sure its a metal oxide or metal film type with some kind of flame proof ratings.

Well the resistor was either spec'd too close to the actual wattage its handling or some other component on the board is in a fail state and this resistor burnt before it did. I see that a lot with fets.

If you burned a resistor its likely something else in the circuit shorted and so too much current was drawn through it. Shorted power transistors are good for that, such as the BJT transistor in your first picture.
I would test any transistors and possibly your diodes on the circuit if you can for shorts or bad behavior. You may have to remove some for testing as capacitors will sometimes interfere.
I replaced the 2.2 ohm resistor with 2w 2.2ohm
there is a short and replaced the power transistor, the one in pic tests fine to my surprise. I went after a cap and diodes, circuit worked, however, after 30 minutes resistors on the current path got extremely hot.
I called it a day.
