The Auto light comes on and unless there is a problem the Check light will stay off.
When we follow this procedure the Check light stays off until we start going down the road. Usually the first time we have to make a pit stop I'll look in and both the Auto and Check light will be on indicating that there was a problem.
Sometimes we'll wait and no check light for 20-25 mins before we depart.

Just looked on Dometic's website, and the DM2652RBX is listed as a two-way only, not three-way.
Looking at the picture of the panel you posted, it's not a three-way, no indicator lights for 12 volt as normally used on three-way units.
Are you sure of the model number?

There is no indication the DM2652 was a three way refrigerator in anything I located.
The DM2663 was a three way but the control panel is different.
See photos below.
That is definitly a 2 way only (110v AC or 12v/propane) fridge (the model # in one of your pics verifies this). When you have it set to "Auto" the fridge will run on 110v AC when plugged into shore power. If you disconnect from shore power, without turning off the fridge, it will automatically switch to propane (gas) mode and try to light (hense the 12v circuit for operation of the gas valve and igniter.) The igniter will try to light the burner 3 times before "locking out" and the check light comes on. This means that the burner did not light due to either no propane flow (main valve off at the tank or the igniter failed to light the propane for some reason).
Now, if you've been pre-cooling the fridge at home, it's possible that you don't get an immediate check light because the fridge is up to temp and not calling for more cooling. That may be why you don't get a check light for 25-30 minutes but it is on when you make your first stop.
Hope this and previous post help.
