Any solutions for high altitude refrigerator issues?

We have recently been using our Lance camper at some higher altitudes- 7500 ft and above (to escape summer heat) and many nights are woken up by the beeping of the fridge because it can't re-ignite on propane at the higher altitudes. Its a Norcold, and apparently their solution is to have electric hookup at elevations above 5000 feet, but that is not what we are interested in doing.

I checked the Lance forum but no one there seems to have come up with a solution.
Other than shutting it off and re-igniting it in the morning, has anyone found a solution?

thanks,
Sue
