It's not the actual handle or latch that seem to be the problem. In fact, the handle functions fine and the door "pops" open as it should when you depress the handle.

The problem is once the door is slightly ajar, it is very difficult to open the rest of the way. When the door is fully open, it is very difficult to push shut.

I've lubed the hinges as best I could with WD-40, and it didn't do much.

I think it must be the hinges.

I like the idea of replacing the lower hinge, and I will probably try that when I get the time.

Thanks for the responses.
