Thank you Kirk and Old John for your comments.

I do agree that the fuse filament is just like an incandescent light bulb.  They weaken over time and at some point will fail.  And my RV is 14 yrs old, even though relatively new to me.   

After finding (thanks to responses) the fuses under the circuit board cover, I replaced the blown fuse.  The Norcold manual didn't point it out but said to have a repair technician remove the cover. CYA.

As of this writing, I have had the fridge on electric and it has worked fine, heat on the back and cold inside!   Hopefully the 5A fuse just reached it's end of life!

She's cooling nicely.

It didn't work on AC from the time we bought it used a few months ago.

I don't know why the fuse was blown, but assume it had been for some time, seeing it was a challenge pulling it from it's holder.

I do thank you for your input and all that try and help each other out. 

Thanks for your help and suggestions!

I knew I had power before as the light came on in the fridge when door opened.  I also tried plugging the fridge directly to my house via ext cord.

I took the circuit board cover off today and found the glass fuse was blown.  After replacing it, the auto switch now stays on w/o switching to the gas mode.

Now I wait and see if it actually cools the box down.  I'm in a waiting pattern!

Our Norcold N611 works fine on LP.  

However, when plugged into AC and we turn the switch to automatic,  the fridge switched to LP and won't go to electric.

Can anyone be of help please?

Thanks
