My Norcold DF0704 stopped working on 110. Seems to work fine on 12
volt. It was probably original with the boat, so it must be 20 years old.

Replace or repair?

It looks like that model isn't made any more and what I see (on a very
quick look) shows that none of the new ones fit the cutout.

Maybe i just haven't found the right one yet.

What have you all done?

If it's still running on 12 volts that means that the
compressor/condenser is still OK, which is at the heart of the unit.
You could either try to troubleshoot the electrical problem or
continue running it on 12 volts by beefing up your charging system if
necessary.
