I have a side-by-side Whirlpool refrigerator model ED25TE that I acquired in 2003. I have only bought replacement water filters from FiltersFast, specifically the Whirlpool 8171413 except on the last purchase early last year I switched to the Aquafresh WF286. I have never had any issues with the Whirlpool 8171413 filter since the start. When I finally ran out of the Whirlpool 8171413 filter last week, I installed the new Aquafresh WF286 filter. I have noticed that the water is not cold at all when dispensed through the door water outlet. It was noticably colder when I had the Whirlpool 8171413 filter in place. I have removed and reinserted the Aquafresh filter several times throughout the day and the water is not being dispensed cold. The refrigerator side has no temperature issues. When I have removed the Aquafresh filter and shook the water out of the filter, it feels cold. I wish I had not tossed out my last Whirlpool filter so I would know if it is the Aquafresh filter or something else. I feel that the water is bypassing the filter so the water is not cold. Is there something I should check? With my sister's family of four staying at my house, they have been using my refrigerator water dispenser every day and noticed immedately after I changed to the Aquafresh filter that the water was dispensing lukewarm like what is coming out of the tap than what was before coming out through the Whirlpool filter.
