The other day I flew on a chilly evening just above freezing.
I applied flaps in the pattern, and when I landed, the flaps didn't want
to retract
I had earlier exercised the flaps on preflight without problem
and before the plane was put away, the flaps went up OK.

I guessed that the actuator froze up, so it probably needs lube to keep
the water away.... The flap motor fuse checked OK of course...

Any thoughts?

Brian,

The most common cause of "frozen flaps" in Cessnas like yours are the
limit switches on the flap actuator, rather than the actuator itself. A
judicious application of a heat gun, through the appropriate inspection
panel, will free them up for a while. They are relatively inexpensive
to replace, however, and that's what is needed for a more permanent fix.

Happy Flying!
