GE SideBySide Ref GSS25VGMD WW

The Ref door is too easlly opened. It stays shut, but without the 'suction' feel it had a couple of days ago. (The freezer door is tightly shut, like the Ref door was and should be.) There is nothing in the way, it is clean and in like new condition, not warped, etc. The Ref seems to hold the temp OK, as it continues to stay around 32-38. I do not notice any frosting up or other problem. I do note that the warm air coming from the floor area is not as warm as it was earlier -- it is still warm, but not as warm. I did note the fan for the Freezer running yesterday, but haven't specifically noted it today for either the Ref or Freezer.
I have had a house full of company the past few days and the door has been opened more often and more ice used (normally it is only myself here) -- would that have any effect?
Do you have any idea as to what the problem might be?
Thank you so much -- Linda Gayle
