Narrative:

Approaching vny at 3000 ft, cleared visual runway 8 bur. Started configuring for flaps 15 degrees and noticed that the flaps would not extend nor retract out of the 5 degree position. Performed a go around, advised ATC we needed a space to hold for a bit, then informed passenger. Went to a holding while performing QRH procedures and consulting dispatch and maintenance controller. After computing data at bur for a flap condition 'between 1-5 degrees,' and conferring with dispatch, it was deemed that the safest and most prudent course of action was to divert to lax. Approach and landing uneventful on runway 25R, with a vref of around 160-165 KTS. Maintenance met us at the gate and aircraft was eventually found to have a frozen hydraulic flap motor.

Title: B737-300 CREW HAD FROZEN TRAILING EDGE FLAPS. THEY DIVERTED TO THE NEAREST SUITABLE ARPT.

Narrative: APCHING VNY AT 3000 FT, CLRED VISUAL RWY 8 BUR. STARTED CONFIGURING FOR FLAPS 15 DEGS AND NOTICED THAT THE FLAPS WOULD NOT EXTEND NOR RETRACT OUT OF THE 5 DEG POS. PERFORMED A GAR, ADVISED ATC WE NEEDED A SPACE TO HOLD FOR A BIT, THEN INFORMED PAX. WENT TO A HOLDING WHILE PERFORMING QRH PROCS AND CONSULTING DISPATCH AND MAINT CTLR. AFTER COMPUTING DATA AT BUR FOR A FLAP CONDITION 'BTWN 1-5 DEGS,' AND CONFERRING WITH DISPATCH, IT WAS DEEMED THAT THE SAFEST AND MOST PRUDENT COURSE OF ACTION WAS TO DIVERT TO LAX. APCH AND LNDG UNEVENTFUL ON RWY 25R, WITH A VREF OF AROUND 160-165 KTS. MAINT MET US AT THE GATE AND ACFT WAS EVENTUALLY FOUND TO HAVE A FROZEN HYD FLAP MOTOR.
