Howdy,
I have a year old Whirlpool fridge. Water filter change light did its
green-yellow-red routine right at six months, and again at one year.
I am strongly suspecting now that this is a timer, and their is no H2O
quality being measured. It would be surprising if their was a
conductivity meter in an $1100 fridge. And the filter was around $50
at Lowes.
Just wondering (yes, I live alone! Too much time on my hands!)

My WP fridge filter indicator will come on sooner if I use more water. I
am guessing that they use a simple timer to keep track of the time that
water is flowing through the filter (plumbing) either by using a
pressure or flow sensor of some sort or maybe just timing how long the
water tap switch is held down.
You can get better deals on filters on-line something like 3/$100
delivered.

I just ignore mine. Water is the same. Water pressure is the same; so why
bother. YMMV

I expect it's an integrated time and use monitor, where it starts with a
base time of six months as the maximum filter life based on bacteria
buildup or some such, and deducts additionally off that time for the
amount of use the dispenser and ice maker get (remember the ice maker
goes through the same filter).
Personally, I just reset the light whenever it comes on and replace the
filter when I feel like it. The source water fed to it is pretty good,
so I don't expect it wears / clogs at any appreciable rate.

I don't know how they work but bacteria over time is a consideration also.
Will the water still work if you just remove the filter? If so, I'd leave
it out and put an in line filter in its place. They are about $10 to $15 to
replace.
