The captain and I put on our oxygen masks and began working the problem. The captain flew and talked on the radios while I ran the appropriate checklist. The captain [advised ATC]; we returned to [departure airport] and landed uneventfully overweight. Arff met us after taxiing off the runway and cleared us to taxi to the gate. No damage was noted.
