Get a real A&P to check out the flap situation. If its
not the breaker it could be the flap motor (one of the
reasons I do like manual flaps).

As far as why you didn't notice that your flaps were
not working... well... that is disturbing. I notice
*every* little sound, motion, vibration or whatever in
my airplane.

I hardly ever land with full flaps unless its a short
field.
