Can anyone confirm this resistor value?
I'm guessing the leftmost colour is grey, but I'm wondering what the device is that would have an exotic high-precision low value resistor on an SRPB circuit board.  

If you can convince yourself the leftmost colour is to be ignored for value, you have a very ordinary 220&Omega; 5% resistor.  Wikipedia says that a fifth band is sometimes used as a temperature coefficient.  Grey = 1 PPM/K.  (White and silver not listed for this.)  As this is in an oven, it may well have parts specified for good thermal coefficient.  But a 1 PPM/K resistor is also pretty exotic.  Might just possibly be a temperature range indicator -- but I know of no markings for that.



Digikey's standard 5-band decoder says 22.1&Omega; 0.05%, which really isn't convincing.
