I have just swapped out the electronic temperature controller in my
mum's fridge, as the old one had failed, and was appearing to brown out
when it tried to turn the compressor on, so it would reset its self, and
then wait a few seconds, turn the compressor on in a continuous loop.

I now have the old module apart, and there is a 4K7 resistor that is
measuring about 10 ohms (out of circuit). I expect this is part of the
step-down voltage regulator arrangement, and is the cause of the problem.

It looks like a standard carbon film resistor, except it is much larger
than a 1/4w one - probably about 8 x the size.
Here is a link to some pictures of it, one comparing to to a standard
1/4w one

It measures 6.9mm wide by 13mm long

Any idea how I would find out the power rating of this so I can get a
replacement?

Thanks!
