Narrative:
Departed ewr and landing gear would not retract. Performed unable to raise landing gear abnormal procedure as per airline's aircraft flight manual. Landing gear remained down. Aircraft was positioned about 10-15 mi from airport. Advised ATC and returned to ewr. Did not declare an emergency. Aircraft landing was uneventful. Had to stop on runway because of landing gear door dropped down during rollout (as per abnormal procedures). Maintenance found landing gear bypass handle stowed,but not properly. Unable to detect from normal preflight of exterior aircraft. Gasket from handle appeared jammed in seat. First officer preflted and stated handle was flush. Mechanic found handle flush with seat, but further inspection found gasket jammed. Maintenance advised crew that this would be difficult to see on a preflight. Maintenance was advised by maintenance control to replace gasket.
