Fridge not working on gas!

[AG 2602]

Hell All
Meant to be going away tomorrow with no EHU.
Just tested the Dometic fridge and it’s working when the van is running but not on gas. Beeping sound and warning flashing light on control panel.
No clicking sound when it’s switches from electric to gas?

The hob is working so there is gas going into the van.

Any help much appreciated.

Thanks
