how do you get 16? red 2 purple 7 black 0 gold *.1 =27

like @markba633csi said - I misinterpreted the colors as "brown blue..." THEN saw what you wrote.

Gold is in the wrong place to be a multiplier.
RED = 2
PURPLE = 7
BLACK = 0 x 10
GOLD = 5% tolerance
ORANGE = failure rate

... so, it is a 27 ohm resistor. If in doubt, just measure the device.

I would measure it as the colors are hard to see. Per above would be 27 ohms based on those colors.

You can always substitute a tighter tolerance, but that is a 16ohm resistor, not 27ohms...

Err scratch that, I see you said that's red and violet - sure looked like brown and blue to me.

Being color-blind or partially color-blind is a real problem when working with electrical items. I KNOW, that's me.

27Ohm 3% tolerance. Tolerance is a key factor. It's supposed to fail first. It is likely to prevent failure of a more expensive less replaceable part further along in the circuit.

If you will allow me...
To dispel all doubts and guesses about the resistance, you need to measure the value of this resistor with a multimeter (ohmmeter).
It is not burnt, it only has a broken connection tip - so its resistance can be measured.
NOTE: When measuring resistance with a narrow tolerance and a value of several to a several dozen ohms (as in this case), it is necessary to measure the resistance of the measuring leads (multimeter's "own zero", usually 0.2 to 0.5 Ohm) and subtract it from the measurement result.

I agree with these guys, power resistors tend to get "warm" and the colors can shift. When in doubt, get the meter. Even a heap o' crap meter with a half dead battery will get you in the ballpark close enough to be able to deduce the colors and nail down the nominal value. That will end all speculation, as well as any doubt about the online calculators, of which one SHOULD maintain some healthy doubt... I have found that results from some of these disagree with each other. Not that they're all faulty, but you've gotta learn to trust one before you can take it to the bank.

A meter (even a sketchy one) will solve the puzzle with certainty.

Here's another good one:

5-Band Resistor Color Code Calculator

Calculate the resistance of a 5-band resistor using this resistor color code calculator

circuitdigest.com

There's even a 6 band version (last band is temp coefficient in ppm)

Apparently no band for the wattage rating-

i did try to measure the ohms with my meter. its really hard to do it with everything in place. when i have the replacements i will remove the board and check the resistance before i reinstall everything. i do think its a bid weird there is no power rating indication. but maybe its obvious if your experienced.
