What's wrong?
The door operator and baseplate on the 2021 Nova Bus Lfs control passenger door movement. The pneumatic door operator uses air pressure and linkage hardware to open or close the door when the driver activates the switch. A rotary plate inside that assembly transfers that motion to the door mechanism.
On these buses, the welds on the rotary plate output shaft can fail. If the weld breaks, the rotary plate can separate from the door operator, so the door no longer responds as designed. Nova Bus reported door malfunctions while the bus was stationary and one case of a door opening while the bus was in motion.
There is no warning sign before failure. The driver does not get a clear early symptom before the door operator stops working correctly or the door opens unexpectedly.
