AC and Fan not working

In a 2015 DSDP 4312. We have 3 roof ACs and for some reason I started getting an E7 error on the #2 roof AC. I went to the breaker panel (coach one in bathroom) and one had tripped, reset it but still getting the error. This is plugged in to shore power, 50A service. I made sure when testing all other AC units were off. Still the same. It sounds like the compressor kicks on and then nothing else and kicks off and error. I did try to turn on just the fan (no AC) and it's not working either.

Wondering if there's some kind of starter relay or similar that could be the issue here, basically the fan won't kick on so the panel errors out. Thanks for any help.

Why not swap the capacitor with one of the other 2 which would rule out the fan motor as the problem. I have had to replace the capacitor on both of ours as well as 1 fan motor in the past couple years.
