Question about Dometic Rooftop RV Air Conditioner

1 Answer

We have a Dometic Duo Therm airconditioner on our RV. The model number is 620515.331. When I climbed up on the step ladder to have a look at the roof of the coach, I noticed that encircling the unit, it looks like a kingsize bird's nest replete with twigs, grass, etc. Nothing seems to be alive in there, so we can only hope that all this stuff was sucked into it when the air was on. We have only used it a few times. We have no manual with the info from the RV dealer. Can we take the screws out that go around the cover and get at the shrubbery?

Yes once you remove the screws the shroud should come right off. The cover is just that, the cover for the unit. You might think about putting some screening around the opening to keep this material out.

Duo therm rv airconditioner pulls 17 amps, with compressor running. It cools very well though.

Check incoming voltage first to make sure it's not dropping under load, or low to begin with. Any poor voltage or long runs of extension cords could be causing voltage to drop, thus raising amperage draw.

Installing rv roof airconditioner heat strip

I see what you see also in the manual. The difference is the Heat Strip package that part is optional and the 600212-001 with the optional heat strips becomes the new 600315-001 I talked to Dometic Duo-Therm and the models are the same but they both are not heat pumps but the new heat strip package comes on when told to go into heat mode when you change the thermostat to heat. The part you purchased will fit both model numbers you listed for your roof top air conditioner. Thanks, Sea Breeze

The refrigerants in these units is R-22 But there is no reason to think the system has a leak. You need to confirm that the comprerssor is running. This requires an ammeter. If you don't have one call a technician.
