If that is the case your cooling unit is developing obstruction/blockages and overheating therefore the temp switch is tripping
Although operating while moving is typically NOT an issue I noticed that the fridge worked fine when parked overnight/stationary and the E-3 events were happening when travel.
That suggests that the coolant IS overheating due to gravity flow being interrupted ---- are you traveling on steep grades?
Once coolant has been overheated...crystals form and plate out obstructing natural flow...more overheating events/more crystals/more plating out/more obstructions---etc
Accumulative and permanent
