Narrative:
We were in the landing pattern at sbn. My first officer asked for 15 degrees of flaps as per our normal procedure. I selected the flaps with no response from the 'running' light or the degree indicator. We elected to abandon our approach. Informed the tower of our problem and we were cleared to the OM at sbn to sort out the problem. We complied with the abnormal checklist for this problem with no success in moving the flaps. After a lengthy discussion with our maintenance control, they suggested we cycle the flap motor and GPWS computer circuit breakers. For reasons yet unclr to me, this cycling of the breakers cured the problem. We landed without incident. A local mechanic in conjunction with our maintenance people checked the system out completely and declared it svcable. We flew to fwa without further incident. Our maintenance people have promised me a detailed explanation pertaining to these breakers and what actually occurred to cause this problem.
