Replacing a FXRC filter with a MXRC filter

[digitalsaw]

First off I would like to say thank you for having such a great forum. These are great for the home handiman as well as the professional. I fall into the first category and need some advice.
I have a GE Side-by-side refrigerator. It is called a "Profile Performance" model and I didn't take the time to dig into the model number but I can if it is needed. Here is my story. LOL.
The water in my house comes from a well which taps into a wonderfully clear Florida aquifer. That means my water is absolutely wonderful. We don't get stains in the toilets and the water tastes better than bottled water. We are blessed. I purchased this refrigerator about 6 years ago and have never replaced the filter but my wife recently complained about the taste of the water coming out of the water from the fridge so I thought I would replace it.
I found Filtersfast and purchased the MXRC filter which said it replaced the FXRC. It came in and I went to install it. Two things ocurred:
1. I shut off the water line to the fridge and took the old filter out. It looked identical to the MXRC excetp the very top spout on the old filter had a cross on it and the MXRC did not. When I felt up into the hole the filter attached to I could feel a spring loaded nipple sticking down. It made sense to me that this cross would put that up and activate the water from flowing. I put the new filter in anyway and sure enough I had no water coming out of the fridge. I figured I may have the wrong filter so that is my first question.
2. I went ahead and put the old filter back in figuring I needed to find out what was going on and now no water is flowing to through the fridge. I obviously turned back on the water to the fridge.
Does anybody have any ideas? Thanks in advance.

First, be sure the water is fully open to have full water pressure to filter.

I have not heard any problems with the MXRC replacing the FXRC, they are interchangeable. On the very tip of the MXRC nipple, there should be a 3-way divider or 'cross' that should open the valve in the receiver.Does your MXRC have this?

Is there a way that you could post a picture of the filter nozzle for better clarification?

Alex,
Thanks for the response. The water began to flow again so it may just have been an airlock but you hit it on the head. The MXRC replacment filter does not have the cross in the tip which would push up the nipple on the refrigerator. My original filter has that cross. I double checked and it was indeed the one they said was the replacement for the FXRC. Ideas?
