Transfer switch making a loud clunk when air conditioners cycle on and off.

[Jayruger22]

I have a 2017 raptor 398ts, just recently within the last couple of days I have heard a loud clunk sound coming from under the master bed. It happens about ten seconds before an air conditioner unit comes on or goes off. I have all three set to auto and they sequence where only two run at a time. As far as I can tell it's coming from the automatic transfer switch. I have a progressive industries surge protector system and voltage and frequency all are good. It shows no errors on either circuits.

Any ideas, could it be a sign of my transfer switch going bad? I just picked the coach up two weeks ago new, so I would be a little disappointed if already a bad transfer switch.

Thanks for any insight.
