RV refrigerator not working

I have a 2021 Keystone Sprinter 3190 RLS. We have it plugged into 30 amp power right now. We left it overnight with nothing on except the refrigerator. When we arrived just now the refrigerator is not working. We have checked fuses and breakers. All other lights and A/C units come on but still no power to refrigerator. Any ideas?

Make and model of refer?

If it’s an RV fridge, you’ll need 12V for the fridge to turn on. Don’t just look at the fuses, use a meter and test them. Then go outside and take the lower access cover off. Make sure you have 12VDC on both sides of the plastic connection block.

If you do then you’ll need to check the control board for blown fuses.

You say "A/C UNITS" which would suggest TWO and your trailer is 50amp. ??? Plugged into 30 amp you may be missing some circuits depending what adapter you are using. If a residential fridge the inverter may not be getting power to charge its battery back up.

3 different fridges listed for that model, an RV fridge (absorption), a 12 vdc , and a residential fridge with inverter. Which one do you have?

If you have 2 air conditioners and they both work, then let’s turn our attention to the inverter. It should have “pass through” so that when plugged into shore power it allows power to the fridge.

Is the inverter getting power? Is the fridge plugged into a GFCI and possibly tripped?

You've got 2 A/Cs and they both work? On 30A shore power plus trying to power the inverter and converter??? If you're doing that you have fried, or will fry, something.

If it's a res fridge is the inverter on? If on there should be an indicator. If not, is it turned off? There should be a switch/button to turn it on. If that doesn't work is the breaker on for the inverter/inverter outlets? Is the bypass switch to the inverter turned off? Is the fridge turned on? Lots of easy things to check since we don't have any idea the sequence of events that lead to the dead fridge.
