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?

Thanks
