Dometic Refrigerator Tips
Our original Dometic refrigerator has mysteriously quit cooling while on shore
power. I
opened the door and found it was warm inside. Checked the light at the bottom
and it was
showing red. I turned the unit off, waited awhile, turned it back on and the
light was green.
Checked it a couple of hours later and still no cooling.

Any ideas on what might be the problem? I had the circuit board replaced about
5 years ago
and it has worked great ever since. Could it be I need a new board again?

Thanks in advance for any help, suggestions.

Eric,

Go to http://www.rvmobile.com/. They have an excellent
troubleshooting guide. I just replaced my Dometic with a larger
Norcold for $1000. New circuit boards for your fridge are about
$200.

Hi David,
Will do! Thanks for the information. How did you fit a larger fridge into the
old Dometic
space?

Eric,

Height is the only issue for a larger fridge. I removed the shelf
in the compartment above the fridge and moved it up the required
amount. Bought the fridge at bigdiscountrv.com. Good price, no tax
and free shipping to me in less than 3 days.

Dometic Refrigerator Tips
Hello Eric:

Lets explore some basic troubleshooting on this one.

First, the button at the bottom that was red, now green, after resetting is
for the LP only. Your refer, if not on automatic needs to be switched over
to LP at the eye brow of (panel) of the refer.
12 vdc
Now, no matter if on ac or lp, the refer board still needs 12 vdc to power
it up. So you need to check to be sure there is 12 vdc at the terminal
strip in the out side refer compartment. The terminal strip is at the base
of the refer just under the circuit board. If 12 vdc is present, there are
2 or 3 fuses on the circuit board that needs to be checked.

110 vac
Next, you need to ohm out the 110vac heater located beside the boiler tube
on the right. Find the wiring and trace to where the connectors are. making
sure power is off, undo the connectors and measure ohms across the 2
wires. You should read between 1.2 and 4 ohms, or a reading other than 0.
if the meter reads 0 then the heater is bad, replace it. If it ohms out,
then re connect the wires, apply 110 vac power, turn on the refer to manual
ac, then check for 110 vac at the connections going to the heater. The
boiler tube should be very warm to the touch or you can feel the insert
tube on the side of the boiler to see if it is getting hot.

Lp.
Switch the eye brow to manual lp and you should hear a click click click of
the igniter/re igniter trying to ignite the lp flame. go out and make sure
it lights, you may have to remove the cover plate to see the flame or use a
mirror.

If the AC heater is getting hot and the boiler tube is becoming warm, in 3
to 4 hours you should be able to feel the shelf plate in the refer getting
cold. If it remains warm or hot, then the coil unit of the refer is blocked
and time for a new unit.

If you need a new unit. There was a recall on Norcold units, due to fires
starting, so be sure to check that model and serial numbers if you go
Norcold. Most techs and RV repair places are reluctant to even work on
Norcolds right now because of law suites.

Personal I still think the Dometic is a better unit, but that is like tires
and insurance, everyone has their own ideas.

Start with the voltage check and take it one step at a time.

Safe travels,

Dometic Refrigerator Tips
Hi Ralph,
Thanks for the information. It seems the unit came back from the dead after I
shut off the
12 vdc to the back of the coach and then put it back in service. It took a long
time to cool
back down but then we keep having 100+ºF days which doesn't help. I don't think
the fan
located in the outside compartment is working anymore. Got any info on a good
replacement for this fan? Is it on a thermostat or should it run when I flip
the switch in the
panel next to the kitchen sink, regardless of temperature? Better circulation
through there
might improve cooling on these hot days.

Replacement Fan...Over a year ago I bought a surplus computer fan,
$4.00, and installed it using a household thermostat. It's set to run
when temp. gets to 90 degrees. It's still working, and quiet too.

Dometic Refrigerator Tips
Hi Eric:

My apology, I had inadvertently over looked this E-mail. The original fan
does or did have a thermostat in line with the 12 vdc power and was set to
be on at 90 F and off at 70 ish F. When I replaced my fan, the large 12 vdc
fans found at truck stops or RV parts, I took the thermostat out of it and
went directly to the operator controlled switch on the panel.

Curt's solution worked for him as well, and not a bad one. I just like
larger fans pushing more air through the coils and out the top of the
stack. Either way, air is moving and that is the preferred thing.

I did an experiment out in Phoenix (119 F in the shade) when visiting our
Daughter. I took and umbrella and made a shade for the out side compartment
and it did help cool it down as well. Was going to put the smallest ZipDee,
like over the windows, over the refer out side compartment to match the
rest of the Coach. But that is an extreme, just thought it a good idea,
still do.

Glad your refer reset for you. The fridge temps should be in the area of 36
to 39F in the main box and 6 to 9 degrees F in the freezer, this is the
normal temps.

Dometic Refrigerator Tips
Just a thought but if you have the optional
toaster that extends into the refrigerator cavity
from the left sidewall of the kiitchen it
restricts the smooth flow of air from the outside
panel up thru the cooling coils to the roof vent.
Take it out as I did and it makes a big difference.

Dometic Refrigerator Tips
Eric,
BB has a replacement for the fan. They were reasonable on price compared to
Camping World. It is a heavy built fan not a light plastic one.

Hi Ralph,
Thanks for the information. It seems the unit came back from the dead after I
shut off the
12 vdc to the back of the coach and then put it back in service. It took a
long time to cool
back down but then we keep having 100+ºF days which doesn't help. I don't
think the fan
located in the outside compartment is working anymore. Got any info on a good
replacement for this fan? Is it on a thermostat or should it run when I flip
the switch in the
panel next to the kitchen sink, regardless of temperature? Better circulation
through there
might improve cooling on these hot days.
