Ken and Cydrome's idea to put a thin spacer on the disc to make it easier to release sounds like a good idea. My experience has always been that the magnetism was not strong enough to hold the door open, not that it would not release.

I've never seen this and I have a fair amount of experience with these doors in hospitals.

It is more commonly hard to get them to stay open.

I would suspect a door closer problem first.
