I have a Whirlpool side by side (ED25PExhw00). It is only 4 years
We have noticed that the fridge side was getting warmer and we moved
the controls to the coldest setting.
I have never cleaned the coils. Not sure how that happened. I took
the front panel off and vaccuumed all that dust off. I also took the
back cardboard off and dusted the back off as well.
I did not replace the back cardboard (it also had some foam on it)
thinking that it was supposed to be removed after shipping. I was
worried that the coils were not getting enough air since the cardboard
(about 8 inches high and accross the entire back) only had some slits
After a couple of days, I measured the temp. The freezer is 20
degrees on coldest setting and the fridge is 56 degrees.
I checked the manual and have done everything I am supposed to do.
