The AC and micro work only on 120VAC the fridge should be able to run on LPG too - however it will need 12VDC to run some controls. As the previous poster mentioned, you need to trace your shore power (120VAC) circuits - Usually there is a single point where the AC breakers and the DC fuses reside. Sometimes the AC to DC converter ( and battery charger) is located there as well. On my TT the power cord attaches to the back of a distribution panel behind the circuit breakers - it is possible that a wire has come loose or is broken. That would prevent your shore power from even reaching a CB - unlike your house - there are no master CB - just the ones for the indivdual ckts - AC, Microwave, Outlets, Converter etc. If you don't have a multimeter go down to either your local big box home improvement store, or electronics supplier and get a cheap DMM - usually less than $20.00. It will be invaluable for checking these circuits. Be sure to remember the difference between AC and DC.
