I am not sure you can "jumper" the Dometic thermostats, I believe they use a serial communication link to the control box that is inside the AC unit, which I believe could be the problem here.
It is possible there is just a loose connection.
Here is a
link to the lcd Dometic thermostat, there is a diagram on the last page showing how things are connected in the control/relay box.
On the the white connector, that goes up into the AC unit, the blue wire is compressor power, the K1 relay controls power going through that wire.
Depending on you electrical skill and comfort level, I will let you decide what to try next.
It is possible that connector needs to be re-seated, try that first. might as well make sure all the connectors are seated well while you are at it.
