Question about Dometic Rooftop RV Air Conditioner

1 Answer

Thermostat problem Thanks for replying. It's a 1998 National Tropi-cal motor home. I do not have a good manual on the Duo-Therm thermostat or heater. The picture on the link you sent me looks exactly like the one I have. The part # for the thermostat is 3106463.007(located on the back of the old thermostat). I see that other people have had problems with this same model. I sprayed the push buttons on the unit with contact cleaner and it had no effect. I'm wondering if it is definitely the thermostat or something else. I'm leaning towards the thermostat. I reset all the circuit breakers and checked all the fuses and couldn't find anything wrong. I don't know if their is a fix to the thermostat or if I should just buy another one. I don't know if Dometic has a tech line for this or if they send you to an authorized repair center. What do you think?

Try this # Phone: 1-800-544-4881 Ask for tech assistance, if no luck ask for sales rep. Have your Make, model & serial #'s ready for both thermostat you are trying to use & your AC unit. They should be able to tell you if that thermostat will work or not, and if not, they will give you a part # for the proper one. If no luck with that, send an e-mail, with same info & ask same questions to : (CustomerSupportCenter@DometicUSA.com ) or check link below out for same info.

My Duo Therm furnace was working last night and not this morning


I would make sure there is power to the unit before I attempted any repairs. Gas being available will not allow the thermostat or gas valve to operate if there's no power to them

Installed a new Filtrete thermostat on a new Carrier high-efficiency furnace. I followed instructions exactly. It doesn't work. What did I do wrong? Furnace was installed in December. Broom handle...


Hi smargyle,

Welcome to fixya!

I can provide you with diagrams for the old Carrier therm and for the new Filtrete therm. But, I would need to know what the model numbers are for each therm plus how many speeds AC you have.

Please reply back with that information and we will get your AC back in working order.

Thanks,

Handie Andie

Have a duo therm ac and the low ac and low fan not work -


Thermostat on wall, or manual controls at AC? Did it work for you on low before now? Reason I ask, is that normally they are only a 2 speed fan ( low and high) so if it's a wall thermostat and has been changed from original, perhaps it the way the thermostat is wired.

A duo therm thermostat (p/n 3105058) was removed because it would not operate the air conditioner/heater in a firan fireside camper. it was knocked loose from the wall damaging it.the thermostat is for use...


a. Remove the cover of the thermostat.
b. Connect the RED wire from the air conditioner
to the “RC” terminal on the thermostat.
c. Connect the “YELLOW” wire from the air conditioner
to the “Y” terminal on the thermostat.
d. Connect the “BLUE” wire from the air conditioner
to the “H” terminal on the thermostat.
e. Connect the “ORANGE” wire from the air conditioner
to the “G” terminal on the thermostat.
f. Push the thermostat wires into hole in wall and
fill excess hole with insulation.
g. Mount thermostat base to the wall with screws
provided.
h. Check all thermostat wires on base to ensure
they are completely clear of the bimetal coil of
the thermostat. Adjust if necessary.
i. Replace thermostat cover.
If nothing operates on the air conditioner, remove the
return air grille assembly and verify the red, orange, yellow
and blue wires are properly connected (red-to-red,
orange-to-orange, etc.).
Next, disconnect the red wires and check for 12 volt
DC between the red wire from roof section and the orange
or blue wire from roof section. If no voltage received,
refer to Section F2. If voltage is received, the
problem lies with the thermostat or thermostat wires.
Next, disconnect all 4 wires (red, orange, yellow and
blue) from the thermostat. With the thermostat set on
COOL mode, FAN mode set on AUTO and HIGH, and
temperature selector set lower than the room temperature. Check for continuity between terminal RC (red wire)
and terminal G (orange wire); and RC (red wire) and
terminal H (blue wire). If continuity is achieved on each,
proceed with the next step.
Set fan switch to LOW. Continuity should NOT be present
between terminal RC and Terminal H, but present between
the other terminals (Y & G) and terminal RC.
If all of the previous checks are good, the thermostat is
good, do not replace it. If any one of the previous checks
are not correct, replace the thermostat.
