Dometic RV Thermostat Basics

In this video, we will look at the Dometic CT Single Zone RV Thermostat that comes in many RVs. It has several features that are fairly easy to understand and a few features that need more explanation. The thermostat is prone to have issues if you don’t understand an important feature of the unit. We will walk through each of the main features to give you a solid understanding of how your thermostat works. We’ll also talk in detail about a problematic design issue with the thermostat.

The prior owner of my Puma had one of these installed. The first thing I tried to do was *push* the buttons. After I figured out you didn't have to I kind of like the touch function. Thank you for the informative video. After watching this video I was thinking it might be a good idea to buy an extra face plate to keep in the trailer just in case.

[@JohnMarucci]

Having an extra faceplate isn't a bad idea at all. Once the small foam pieces at the buttons in the faceplate get compacted the buttons tend to fail occasionally. Thanks!

Great rundown. I'm currently on the hunt to get the controller to stop flashing E4. I cleaned the filters, cleaned the evaporator and condensor. And I've performed a reset at the control. Next step, turn off the 50-amp and see if that resets the unit on the roof. We appreciate what you do John.

[@JohnMarucci]

Glad the video was helpful. By "performed a reset at the controller" do you mean you removed the thermostat faceplate, waited 10 seconds or so, then put the faceplate back on?

[@rvfamilylife]

@@JohnMarucci no, I powered it off, held the mode and the up for 3 seconds until I got 2 lines. Then hit mode again, and it turned back off. Then when I turn it back on the Temp settings went back to default.

I had the problem with the touch sensitivity of the thermostat from when I first got my new Rpod. The RV tech showed me how to fix it by pulling out the foam blocks slightly to decompress them with a tweezer being careful not to tear them. Once he did that I've been careful not to push the buttons and haven't had a problem since.

[@JohnMarucci]

Great point Mike. Mine was too far gone. For those who catch it soon enough, they can save the money on a new faceplate with your solution. Thanks again!

I been researching getting the Brisk 2 13.5k and putting a Thermostat in with it though I wonder if there is another Thermostat that can be used. ?

[@JohnMarucci]

I am not certain what would be the best replacement. If you do try a different brand, be aware that not all wiring may be aligned for a simple replacement. I put a new cover on mine and haven't had any issues since. All the best!

[@mattcorbran720]

Thanks John for the great video. Have you had any issues of the unit cycling on and off and the coils freezing. Curious if you had any suggestions for that on hot humid days.

[@JohnMarucci]

Sometimes if it is really hot and humid, the coils can ice up if the unit is running a long time. Basically you may need to let it thaw out before turning it back on. You can run the fan a while and keep the compressor off to expedite the melt. If the unit is older or you have been in areas with lots of debris in the air, you may need to clean the coils (which should be done regularly) and this can improve performance. I had a bunch of milkweed in my coils recently from a trip in Michigan in June that junked up my coils. Makes a difference in performance if you keep them clean. Thanks!

[@kevincarlin604]

What about the Micro-Air EasyTouch RV Wifi thermostat? It's a drop in replacement for this with the 351 model. Like the NEST for the RV.

[@jasonpollard7157]

I'm getting a e4 code and only able to run the fan in keystone Montana.... the rear ac has zero issues.... should I check for corrosion on the wires ... clean them maybe?

It is located within the unit. There is also a temp monitor probe in the fins of the A/C unit that sends a signal back to the control unit.

[@stephanieroy4566]

Hey John, any insits on the unit freezing the coils when the ac is on. No matter temperature or fan seating (auto,high or, low)

My dometic AC with the same controller simply stopped working this morning, any insight on what might be going on.

[@JohnMarucci]

I am assuming that you are plugged into shore power (30 amp) and that all your wall outlets are working fine in the RV? If so, check your fuse box to see if something tripped the A/C fuse. Also, can you get the fan to run on low or high from the thermostat? If you can, then the A/C unit is likely getting power, since the fan that runs is in the A/C unit. Let me know.

[@brendanpetit434]

Hey John. I have replaced the original one. My problem is the unit will keep getting cold way past the setting. The unit will no turn off. What do you think.

[@renatestepro5167]

Thank you John awesome video, easy to understand even for a non tech like me. Question, and excuse me for the dense question. I know the furnace runs of propane, so that means the AC foes as well, correct?

[@JohnMarucci]

A/C only runs on shore power, so unless you have a robust inverter, you have to be plugged in for the A/C to work.

[@renatestepro5167]

@@JohnMarucci Yes I have a regular plug in installed professionally, that powers the whole RV, I just wasn't sure if it runs of propane or power. . Which is really great in my case. Power is cheaper the propane lol.Thank you so very much. You are great in explaining things to old single perma campers like me.

[@adg1017]

This is a dumb question, I’m sure, but can the furnace run on electric power if you’re out of propane? Thx!

[@JohnMarucci]

I don't know of any electric furnaces in RVs. I do use an electric foot heater fairly regularly when plugged into shore power to keep propane usage down.

[@lynnmatheis1862]

Great info! How long should it take to replace this domestic thermostat?

[@JohnMarucci]

I only replaced the faceplate. It took less than a minute. I would imagine that if you replaced the entire thermostat, that it may take up to an hour to ensure you connect everything correctly and test it out well. If you do a full replacement, you may want a more detailed video showing each wire being reconnected. Thanks!

If you push the up and down arrows at the same, it should toggle the display between Fahrenheit and Celsius.

[@andrewolson703]

The problem I had with both this style and the old push button one over winter they would quit working. When the ac was on and cooled down to temp, you would have shut off. Then back on to get the ac to turn back on. I had to put a new one in every year. After 5 new thermostats I ended up going with a Micro Air thermostat.

I would likely ask on my trailer brands Facebook group next, to see if anyone else has suggestions. Thanks.

If you leave the AC on auto how often does the AC cycle on or at what temp does it happen? I had mine set on auto and it got to temp then turned itself off and the temp was 10 degrees higher and it never came back on.

[@JohnMarucci]

Cliff, sounds like the thermostat isn't calibrated well as 10 degrees is a pretty big delta. Mine usually kicks on when it gets about the temps set and sometimes stays on pretty long after it gets below the required cooling temp (3-4 degrees). I believe there is a two-year warranty on the thermostat and would think you could call Dometic (or your dealer) to get a replacement if it is not working properly. Thanks.

With a dual A/C unit, you may have a separate breaker for each unit. First thing I would do is to check the fuse box in the RV to ensure nothing has been tripped. This can happen if you are drawing too much juice from being plugged in, especially if you need 50-Amp to run both A/Cs and are plugged into 30-Amp service at a campground. Let me know how it goes.

@@JohnMarucci thanks the response. All fuses are good. Both breakers, controlling front and rear AC appear in working order. The front AC has only been used a handful of times since we bought the rig new. Frustrated.

Sounds like time for a service call. I had one that failed under warranty and got it fully replaced.

My touch screen has been abused since we bought the Pod. Luckily it still works! Where did you buy a replacement touch screen John?

[@JohnMarucci]

Tim, I picked up a new unit on Amazon and just used the screen from it. So I now have a spare unit if needed. This black one may not be identical to the white ones in the Pod. Here is a link to the unit on my store if interested: amzn.to/3lLahQa

[@PhotographybyTimWMoore]

Thanks John! Also, I never used the feature of over-riding the auto-fan with the low fan setting at night. Every time that fan kicks on I wake up! With the continued low fan I may just sleep through the night now! We experienced our first flat tire on the Pod on Monday during our trip home from Spokane. Thanks to the PMS , we stopped in time with the warning buzzer to save us from having a blow-out. Now I feel much more secure with the display screen showing air pressure and temperatures while towing the Pod.

[@JohnMarucci]

Tim, glad you were able to take care of the flat tire before it caused any damage via a blow out! I use my TPMS on every trip and it is has been a great knowing the psi and tire temps as I am traveling. All the best!

My AC is 15,000 btu and my generator is a q6500 briggs and stratton inverter generator. It states it has a 5000 watt normal running capacity. This generator will not run my air conditioner. I may have to install a soft start in my unit. Is this normal but my generator is so massive. Thanks for posting.

[@JohnMarucci]

Likely, the 15k BTU unit is drawing much more power upon start-up than listed. I would think a soft-start should solve for this. Thanks!

[@crissmane]

I just purchased my rv with this setup. My AC set on low will occasionally just shut off in the middle of the night. Sometimes it’s just for a couple seconds, then turn back on, ramp up the fan speed to high, then back to low, and continue running. Or, the ac will just shut off completely. Any ideas. The rv is brand new and used only two nights. I am certain that the setting is NOT on auto. Thank you!

[@JohnMarucci]

Have you tried resetting the unit by pulling the faceplate, waiting 20 seconds or so and putting the faceplate on?

[@crissmane]

@@JohnMarucci I tried resetting the unit by pushing the mode and up bottom as advised by a domestic tech. So…is another method, to literally remove the face plate, and simply put it back on? The tech from dometic suspects a control board issue. It’s under warranty, but inconsistent. In order for it to be covered a tech must diagnose it. Problem is, it doesn’t present the problem all the time.

[@JohnMarucci]

@@crissmane Removing the faceplate and replacing it should fully reset the unit.

Have you thought about a video on replacing the R-Pod storage locks?

[@JohnMarucci]

I haven’t thought about this as a topic since I haven’t had any issues with mine. Thanks for the idea.

[@Channel-76]

@@JohnMarucci I was thinking since all storage (and even entry doors) are keyed the same way. We are all just sharing keys in any RV park.

[@JohnMarucci]

Most main door dead-bolt locks are unique to a degree, but I think you are correct on the cargo locks, that they are less unique. I almost always camp at state parks and feel pretty safe with many other campers around. If I boon-docked regularly or camped more isolated, I likely would make this issue a priority. When my RVs are in public storage I first clear out my cargo holds. I also store at reputable places with security gate and camera. So to it depends on your camping style and where you plan to camp. All the best!

[@dougferguson5581]

Does the thermostat work when the unit is in the low mode. ???? Thanks

[@JohnMarucci]

Low fan mode should kick the fan on. If it isn't working, try resetting the unit by removing the faceplate, waiting 15 seconds, then putting thr faceplate back on.

[@rickrangel]

@John Marucci Now that you've had this thermostat for a while, would you buy it again? I am looking to upgrade my analog thermostat, and was thinking about the Dometic thermostat, would you recommend this product? Thank you.

[@JohnMarucci]

Rick, after replacing the first one, my current one has worked flawlessly. I just remember to never push on the buttons but only tap lightly and it has been fine. I would buy it again. Thanks!

[@rickrangel]

@@JohnMarucci Perfect!!! You just helped me make my decision. I am going to buy it. Thank you so much in helping me make my decision. Oh, one more thing. This does have a high and low fan for the A/C, yes? I have a Mach A/C 15,000 BTU ducted in my 32 foot travel trailer.

[@JohnMarucci]

@@rickrangel Yep, it has the three fan speeds, Low, High, and Auto. Works well if you want to leave it on Low overnight for ambient noise. Auto will turn the A/C on and off and can wake me up at times on a hot evening.

I have mine set to Auto mine is the brand new one with the blue background I'm curious why it says that my house temperature is 50 but when I put it up to 70 it's not working yes I have propane

[@JohnMarucci]

So, you have fan on auto, you moved to the heat screen and set the temperature to 70, and you double checked that your propane is turned on, and the furnace isn’t coming on, correct?

[@ravenwinds9919]

@@JohnMarucci correct

[@JohnMarucci]

Have you double checked that your stove will light on propane?

[@ravenwinds9919]

@@JohnMarucci yes I did that check as well

[@JohnMarucci]

Is the furnace fan coming on at all? It should, then it should fire up. You may want to double check fuses/breakers next if you haven’t. If all that looks good, it may mean a service call.

[@hectorgarcia9509]

I have the same dometic , my gauge turns in but sends no power to turn on my ac unit at all.. any ideas

[@JohnMarucci]

If you are certain you have power to the A/C (your RV must be plugged into shore power via your 30 or 50 amp cord) and 12 volt battery power, and it isn't working, first check you fuse box at the converter to see if the A/C for some reason has tripped the fuse off. If you do have power and no fuse issue, then it likely will require a service call as the A/C may be fried or you may have a wire loose somewhere.

Likely the A/C needs more current than your generator is outputting. Let me know how it goes when you can plug in. Thanks!

Where is my ac reset button on 2020 grey wolf limited?? Do you happen to know??

[@JohnMarucci]

Mikki, unfortunately, I am not familiar with your model. There are some basic things to try. First, flip the breaker for the a/c unit off then back on at the fuse box. If that doesn't do it, then you can fully remove the dometic thermostat face plate and then put it back on. You'll need to wait a minute afterward, then the thermostat should be reset. If you are not comfortable doing either of these, you may consider a service call to your RV dealer or a service tech. Thanks!
