In my 10 year old home I am having trouble with a couple GFCI

GFCI devices have a service life of about ten (10) years in a dry location, and anywhere from 2-5 years in a damp location. In many cases, their effectiveness as a ground-fault devices is long-gone, whereas they will still function (somewhat) as a normal breaker. There are exceptions - see monthly test below.

Yes, DO test them every month as suggested.
YES, DO replace them IMMEDIATELY the moment they display any sort of wonkiness.

FULL STOP.

Thanks Peter,
I do test most of the GFCI receptacles monthly. They always pass. So
I'll replace the two and see what happens.

I just replaced the GFCI outlets in my house. I had a problem with
triggering for no apparent reason with new GE ones. Replaced these
with Levitons and haven't had one trigger randomly. The washing
machine is connected to one and the electric lawnmower is connected to
another.
