Dometic rm 7401 Fridge 120 ac light is not coming on

I have a dometic rm 7401 fridge. It is 9 years old and always been trouble free. I plugged it in today to cool for a trip tomorrow. The light on the dial for 120v ac does not light up. I have power to the microwave etc and they work fine. The dial does light up in the propane or 12v dc modes. Fuses look good. It will be awhile before I can determine if it is actually cooling in 120 ac mode or if I just have a light on the dial that isn't working. Any suggestions or has anyone had this problem? Thanks.

    Problem fixed. It was a tripped breaker. Please close this as I can't seem to delete it.

    Check the receptacle in the exterior access to the refer. Use a known good appliance to test, something like a 120 volt drill.
    Check fuse on circuit board in exterior access, lower right side of refer.

    On that model...........when switch is turned to AC it will light up IF AC Power is available.

    IF no light.......no AC Power.

    Check that outlet fridge is plugged into is working.
    Could be tripped AC Circuit breaker, Tripped GFCI that feeds outlet, bad socket

    AC Power feeds directly....no fridge fuses/circuit board. So has to be part of RV AC Power Source.




    ON EDIT:

    See you found tripped CB.
    AC Heater Element could be shorted if CB trips again.

    Freezer should start feeling 'cooler' in an hour/2 hours.
