Arrived at location on 3/15/22 - Found door switch not closing. Adjusted the door switch. When the door shuts and stirrers squeaking found inner cavity stirrers open cover and plastic pieces dirty and falling apart. I did clean the cover and rails but they do need replaced. I will obtain parts and return. Returned to location on 3/25/22 - Replaced the stirrer antennas and motors. I replaced the door springs and ceiling plates. I checked ops. Ok ready to use.
