Arrived onsite on 6/9/21 to check left Alto Shaam combioven. Tightened screws in outer door trim. Checked door sweep and found not staying in track. Sweep torn. Will order, return and replace. Returned to replace door sweep on newer Alto Shaam combioven. Proceeded and replaced door sweep. Adjusted and aligned sweep track so inner glass door closes properly. Combioven in service.
