Have a 2016 Bighorn 3270RS with Frigidaire refer; onlycamped twice with this unit. On the secondtrip (while on shore power - only a overnighter) during the night the refer tripped.Reset the Inverter switch in the cabinet unit came back on however, after waking a second and third time foundthe unit off and reset switch each time (an hour or two in-between). Found referoff again in morning reset again and refer ran fine till left campground. In AMwent outside and opened door to where the inverter is located and the Inverterwas making a funny sound (ping) about every 5 seconds or so, also the voltageindicator was going from approx. 11.5 to .005. Anyone experience this problem?

Why are you running it on the inverter while on shore power? Sounds like inverter or the converter is having an issue. Are the 12V lights working OK? Chris

There's an automatic transfer switch in the refrigerator circuit. If you're on shore power, the transfer switch is supposed to use shore power. The only time it should use the inverter output is if shore power has been disconnected.

Check the circuit breakers in your main panel to see if one has tripped.

Also, if on shore power, the Power Converter should be keeping the batteries charged. It sounds like maybe that's not happening either and the refrigerator's inverter is sucking the life out of the batteries.

You may have a problem at the campground power pedestal, or with a loose power cord. You might be missing one power leg of the 50 amp circuit.

Thanks for the information. Found the breaker to the refer OPEN!! Defiantly running on Inverter all the time; might have done a job to batteries.

What DUMM A--; check the obvious - plus I guess I just haven't come to understand auto transfer!!

Again thanks!!!

The question still remains, why couldn't the inverter, batteries and converter keep up with it? Chris

I'm thinking that the batteries may possibly be damaged. They could have a broken cell and only way to find out is to remove them charge them and test them with a load tester. Then also run an amp check on the refrigerator to see what it is drawing to make sure it is in spec.
