I would not conclude that the ATS is bad until verified.

If you are safe working around 240 VAC: remove the lid to the ATS.

Check for power IN as well as power out:

Red to white= 120 VAC
Black to white= 120 VAC
Red to black (on 50 amp connection)= 240 VAC

Sure, if you find the proper readings on the IN side, but not OUT side, the ATS is bad. But I would check, not assume.
