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

Take a good look at the bottom of the unit, in the front, you may have
to remove a cover to do it but look for a small red button. If you see
it press it in, that's the reset button. It might solve your problem.

If that doesn't work, check the 110 volt power input.

That unit run's on 12 volts. It has a 12 volt DC power supply that
runs off 110 volts. When you apply 110 volts a relay cuts out the 12
volt input from the boat and supplies 12 volts from the power supply,
on older units like yours you should hear a clicking noise when you
turn on the 110 volts, if your not the relay might be bad. If you do
hear the clicking the relay is probably good, but their's something
wrong with your power supply. You could:

Have the power supply replaced or repaired.
Buy a small inverter that's big enough to handle the
refrigerator and wire it in.
Leave it like it is and let your charger take care of the
power when your at the dock.
Fork over about $1000 for a new unit.

If I couldn't fix it I'd leave it the way it is until the day it dies
and spend the $1000 on something else. It's your money.
