At FL370; flight attendants notified us of an electrical smelling odor mid cabin from exit rows to aft lavatories. No visible smoke only fumes: they walked the cabin several times searching for a source but found none. Captain asked them to check for overheating PED (Passenger Electronic Device). None found. Meanwhile we began the QRH for fumes in cabin through step 11. Turned off recirculating fans; fumes no longer present. Turned off bus transfer switch; IFE power; CAB/Utility power; fumes no longer present. Long [satellite] call with [Chief Pilot]; decided to continue to destination. Rest of flight was uneventful. Left all equipment 'OFF' that was turned off as directed by QRH.
B737 First Officer reported fumes in the cabin; prompting successful in flight troubleshooting and uneventful landing.
