If it is a 2 way fridge (110 AC and propane capable), then they still need 12V even when operating on 110 AC as it powers the control panel. This is how it knows to switch over to propane when there is not 110 AC available.
So Sundancer 87 may be on to something regarding the circuit breakers near the battery, but some other things would also need to be not working for that to come into play. Are the other 110 AC powered items working?
