Refer change over, quite possibly a stupid question....

The only stupid newbie question is the one that does not get asked!

Seriously, though, it is odd that when my fridge is on auto, there is no indicator light to show that it has switched to propane. If the switchover fails, then a check light comes on. But it can be unnerving to sit there and look at the panel and if nothing is lit, that means it is all ok.
