Duotherm replacement?

We have three 620215.421 units on our coach. Two are not working. I'm thinking I should just replace them as they are 18 years old and the covers are wrecked on them. I don't want to install new covers and spend a bunch of time and money on this age of components.

Anyone done this? Can I just buy new units and install? I don't have a dealer anywhere close so would like to order what I need and do the replacement here. Any suggestions?

I didn't replace the same unit as yours, but I did upgrade the original Dometic Duo-Therm Penguin to Penguin IIs.

You unit may not have a direct replacement, but you should contact Dometic first.

Duo dilemma

I have had three RVs including my newest one with DuoTherms. I was looking at repairing one on my previous RV and one of the dealers said it wasn't economical to repair them because they are nearly disposable so I understand your thinking about replacement. One thing you might investigate is my newest RV manufacturer, Entegra, has switched their vendor to Coleman units because they are evidently quieter. You might want to shop Coleman vs DuoTherms.

Re: Coleman or others. Yes, I should've stated that. I don't really care the name as long as I get a decent unit and it switches with the old ones easily.

I believe you will need to upgrade your thermostats, also

It depends. Just contact DuoTherm and ask if they have replacements that will work with your control boxes and thermostats.

If not, then you're looking at upgrading the thermostat. The thermostat and controller must match.

At about $600 with no way to charge them, they are pretty much throw away... If you're replacing with units that are compatible with your existing controls, then the hard part is getting them up on the RV. They're held in by 4 long bolts.

PPL Motors Parts Dept can be very helpful with information on the DuoTherms and which ones will work with your current equipment.

I contacted Dometic with all the numbers and they sent me the replacement model numbers. I need adapter cables to ultilize the wiring in my walls now and a new thermostat. Expensive, but cheaper than I had expected.

I'm upgrading a HRMH that has two Penguin heat pump/ACs. One unit just has no more cold. She also has the old CCC 4button.
On hers, I'm upgrading the t-stat to the CCC 5 button. Upgrading the good unit's cntrl box to the one that will work with the CCC5. On the new unit, you have to get the cntrl board that works with the NEW CCC rectangle, and then get a conversion kit to make it work with the old CCC5.
Make sense? Old can only be upgraded so much, and new has to be down graded so it all meshes.
If two don't work, I'd just replace the third, put on the new CCCrectangle, and be done.

When I upgraded both my ACs to Penguin IIs, this new thermostat had to be used. It's the best RV thermostat I've used. The CCC II is more like a house unit that the old 4- or 5-button ones.

Just for technical clarification, there are three different Comfort Control Systems.

4 Button CCC
5 Button CCC
12 Button CCC-II

They are not interchangeable.

For each master button control, the power control boards located within the A/C unit on the roof needs to match the CCC.

One further question: I removed the old units and see that there is a small "box" where the air goes to the ducting within the larger standard square opening. Am I correct to assume the new units are standardized and will just drop in and fit the ducting connections, too? I know the outer dimension is standard, and I've got the adapter/wiring harness/thermostat conversion accounted for. Just want to be sure the ducting connection will fit without major mods, too.????

Thanks.
