I had a similar problem with my refridgerator a few years ago where it would
only run on either AC or DC (cannot recall now), but it was a simple fix.
There is a small relay accessible on the back (just sliding the fridge out
from its home) and it had failed. The fridge circuit is designed so the
relay recognized when AC is available (shore power plugged in) so it would
switch over from DC to AC or vice versa. Try checking out your relay,
unless you prefer purchasing a complete new unit.

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.



The ac shows a high drain, then trips the breaker. The dc works just fine.

I'm sure it's a simple fix, if I were smart enough to find and order the
correct part. Since it works on dc, I'll probably leave it as is and
look for a new one.

It's missing a lot of door screws, the door latch is long gone, it's
noisy and probably draws more than a newer design would. While it may
work, and it's probably fixable, common sense says, look for a new one.

When you are not in a hurry you are more likely to make a good decision.
