Info form you that would help the folks here better help you with your no A/C problem would be:
.. year, make, model of RV - you can add this to your signature block so this info is available each time you make future posts....

.. For me to help I need to know:
1. Brand of A/C unit? is it Dometic ( what model ), Coleman ( what model ), etc

2. Is the A/C unit controlled via a conventional thermostat or via In Command tablet in the HVAC menu?

3. You said it completely shut down but you have the fan running... Have you tried COOL and if so did you hear the compressor kick in... there is a delay when this is selected and usually indicated on either the thermostat or In Command display
