I can’t thank you enough for this video. It was super easy to follow your directions. Thanks to you I’m sitting in a cool RV tonight!
Awesome
I just wanted to say thank you. Son in Naval Flight Training in Corpus Christi Texas. Analog relays died it was hot and a 1000 miles from home. Ordered the parts and borrowed your knowledge and she blew cold air. No way without you.
Thank you. I am honored to have helped in a very small way. Tell your son, thanks for his service.
Your video just saved my butt in the middle of arizona. Thank you so much
So glad I could save your butt. he he
Thank you for sharing this! My husband thinks you need to expand your title to include replacing a whole new unit.
Thanks Mery. I have videos on replacing the whole new unit.
Sunday morning, cup of coffee, and your video. Perfect way to start the morning.
Thanks a bunch Robert.
Enjoy watching your channel. We recently purchased a 2010 Forest River Georgetown. We’ve encountered several repair items. You channel has helped immensely. This week we replaced the front Dometic AC, went ahead and upgraded from the 13,500 to the 15,000. Thinking about adding a micro-air soft start to it.
Thanks !
You are very welcome. Glad you enjoy it.
My ac just went out and I was told he would charge 685 to change me over to digital but I ordered the set up for150 and I am going to do it my self thank you
Holy CRAP !!!!! I ain't charging enough.
This video helped me out so much changing my analog to digital
Glad it helped Jeremey
Done fixed the wiring problems, all interior lights, awning, running lights, both slide outs, switched everything to led and replaced all the old 1157 to 1156 Led bulbs on the lamps , anyway I could go on but you get the picture, we are on the a/c units now.
Sounds like it was a mess.
It works. I have a honeywell on a colman analog box to a dometic AC works great.
why?
One it was cheaper going that route. Second I installed a digital box and Stat from domedic and the Stat had issues off the bat. It would work with cover off but not with it on. The suburban gas heater would try starting as soon as I plugged it in the box. So sent it back got another one and it did work. I decided to add another domedic AC to my fifthwheel ductless had to buy control box and Stat for it to work. I had seen someone do it so I gave it a try and it's works great. I did move the domedic control box and Stat to run the new unit cause I liked the larger residential Stat and it worked great with the heater also. And it was cheaper to buy those parts than buy the domedic digital box and stat.my fan quit working just as the one in your video read a lot on the domedic digital box and Stat and they were mostly bad. The stat more than the box. The only thing is you have to use the domedic a analog wiring harness to put in the colman box. The colman box is cheap and the residential stats are cheap cause all you want is a basic stat. I have seen where people use the new Nest WiFi stat but that's a little to far for a RV I think.
ditto. i have a hunter i installed it 5 yrs back. 24V thermostats don’t work on my rig, but 12v digitals work fine. Thou i still have analog board & thermostat has 6 wires.
Might buy the digital upgrade off season as i see it comes with the 3 wire thermostat according to dometic.
Appreciate your making these videos. They are quite helpful.
You are welcome Ken. Glad I could help.
Son, it is EXTREMELY easy to "hook-up" a "Residential" Tstat to a 12vdc RV system. I've had an Ecobee Digital hooked to my Colman Mach8 for years, no problem.
2 speed fan on roof, ducted overhead to entire house. Gas furnace with it's own fan and ducted under floor to whole house.
Make, Model or Manufacture mean nothing for the original or digital upgrade.
If you wanna know how, just ask. 🙂
That’s awesome. I think I said in this video or other videos on this subject that plenty of people say they do this and it works great. I also said I have never seen it work personally. That’s my opinion and you know what they say about opinions. Thanks for watching.
What wires do you use to test to see if condenser and fan works
A friend of mine had a new AC installed and it came with an eithernet plug to control the thermostat and no place for the three wire on the thermostat. Do you have a work around or just get a different box and thermostat from dometic? Great video. Thanks in advance.
Thats a different model. The controls are probably preinstalled, but he will have to run communication wire and change thermostat. That looks like just a phone wire, but Dometic told me that it is wired different from a phone cord, so he needs to get that from Dometic. It would have been WAY easier to stick with the same model that he took off.
@@hillbillyrv thanks for the reply. I told him he need to call and get the box to his new unit that run off lowvoltage wires not eithernet. The company gave him the part number he needed. Enjoy your videos, easy to follow and entertaining. Thanks.
@@dustinkile7705 Glad I could help.
The wires going to the furnace you put new connectors on are they going to the blue wires at the furnace?
Yes
We have what looks like a telephone jack on our 2005 montana 5th wheel from the thermostat up to the box. What can we do to replace the unit?
That is probably a muti-zone T-stat. Get hold of Dometic and they should be able to give you current part numbers.
I ordered a control box for my Dometic unit that has to hook up ports 1 for the AC power and the second one I am guessing for the digital t-stat the only problem is it came without the harness ,but the new control box has all the wires integrated instead of the wires harness , so I am little confused about it the fact that the control kit itself has two hook up ports.
They may have something new that I have not seen yet or the one you ordered is not complete. Not sure.
Can you explain which wires you used to jump to test the control box and verify blower and compressor works?
I will answer you here, so you won't be getting a call from me. I didn't show that in much detail because I don't want to get anybody hurt. You should be able to take a muti meter and figure out where your 120 volt AC is and jumper power to the fan and compressor to see if they run. If you don't have a meter or you are completely in the dark right now, do yourself a favor and hire someone else to do this.
Thank you. This video helped me out alot
You are welcome
Do you have a video of replacing the board in the top of the unit and converting to digital. Or any help with the wiring when the six wire plug does not get plugged in
I don't. Sorry
No one else says you have to change out the control box to change the analog thermostat to digital. Can you explain that?
I would love to see how they do that. That would be like installing Chevy truck parts on a Toyota car.
When connecting the new control box harness wires to the ones running to the thermostat, does it matter which colors are chosen? Apparently, someone previously clipped short my orange wire and I wanted to see if I could just use a different color to connect communication.
Yes. Choose any color as long as you use the same color on both ends.
theres only wiring for my furnace at the thermostat. how do i get the ac connected?
Watch all of my videos on this subject. I think you will understand more.
Just installed my new control box and thermostat am I supposed to be getting 120v coming out of the box as well as going in? Also thermostat isn't turning on any help would be appreciated
Be sure to watch all of my videos on this subject. You should see something that will help you figure out what you did wrong.
i left a message on another one of your videos where do you get the 12v for the thermostat? some other guy took apart things before i got there and I did not see a transformer
I answered that comment. Go check it out.
I did like you said in video, but I get E1 code, I have switched wires(orange to yellow) but still getting same E1 code. Can you help
E1 is a communication error. Check your wiring again.
I have 2 dometic a/c & heat unit combined, I get 12DC and 26AC from the rear unit, I get a few volts from the front maybe 5 etc. anyway the wires are burnt into in the middle of the coach from fridge fire, one thermostat wire is coming from the back & looks to be going straight toward the front unit across the top through the thick styrofoam,, the coach has 2 duo therms, & 2 honeywell stats each hooked to the heat pump, I got both fans running on high & low from jumping and the compressor does kick on, have not tested the furnance ? but will soon, do you think I need to switch both over to digital ? im all for if it aint broke don't fix it, done been there and done that, any info, Is appreciated.
Going digital is not going to help you with the damaged wiring. 1st thing is to get that all figured out.
How do you ck to see if the box is bad
Where did you conect the supply’s cable ?
I have several videos on this subject. Go watch those and I believe your question will be answered.
ive done this but air conditioner doesnt cycle off at desired temp not sure what to do
They seem to have a 1 degree differential both ways so if you have it set on 70. It should cut on at 69 and go off at 71.
I have a Duo-Therm 3107541 Control Box which new control Box would I need to order
That does not look like a Dometic model number. It should have a period and three umbers at the end. If it is anything other than a brisk air, I would probably have to call Dometic to confirm which control to use.
I have a digital unit exactly as you installed in your video. Same exact Dometic digital thermostat. My unit works fine on A/C cool until it reaches the temp. selected at the thermostat. The A/C unit will then turn off...Both the compressor and fan turn off. Then after about 3 seconds, the fan and compressor will cycle back on again. After it comes back on, It will run for approximately 5 minutes or so, then cycle off for 3 seconds, then back on again. It will continue to repeat that process until you select off at the thermostat. If you set the temp all the way down to its lowest setting, it will run normally continuously without cycling on and off until you freeze to death. Would you replace the thermostat first and see if that fixes it? Or would you buy the kit you installed and replace both the control box and thermostat together and hopefully correct the issue that way? I don't beleive I can return the thermostat if I get it by itself and the problem persists. Or, would you simply invest in a nice down parka and keep the thermostat selected at its lowest setting and run the A/C continuously? My trailer is 3 years old. I bought it used recently so I have no idea if it always did this since new or not. But I'm pretty sure it's not supposed to do what it's doing obviously. Plus I believe it could damage the compressor if allowed to cycle this way. Thanks in advance and for your video. Very helpful.
I would replace both and yes I would not allow it to do the short cycle thing. It would be hard on compressor for sure. LOL on the parka. Good luck
@@hillbillyrv Thank you for your response. I will post back on the result. Thanks.
@@hillbillyrv So here's the long version. I purchased the replacement kit from a local RV dealer. I replaced the control box and the thermostat. The unit then developed a completely different problem. The compressor and fan run, but will not turn off no matter what you set the temperature to, (no cycling). Parka still needed. I replaced the new thermostat with the old one. The original problem with the old thermostat returned, (cycling). I ran new wires directly from the controller box to the thermostat and retried both thermostats. I knew it wouldn't fix it but what else am I doing right? Or course new wires made absolutely no difference. Each thermostats own particular problem remained. After going a few rounds with the RV dealer and their tech telling me it wasn't the thermostat, I finally talked them out of exchanging the new thermostat from the kit I bought from them for another new thermostat they had in stock. I installed the second new thermostat and the issue is now completely resolved. I might add that IMO, the technical aspect of how this system works is sound. The thermostat hardware itself is garbage. Especially since you have to shut off the thermostat just to read the inside temperature along with all the other complaints all over the internet with this and other issues. Engineers are a different breed. Once again, thank you for your input and video. Extremely helpful.
@@davidsine4390 glad you go it fixed David. Glad I could help.
Could you tell me what leads you jumped to test the compressor and fan because the video was too dark at that point? I'm trying to get things hooked up on a now stationary 30' camper running on 120v only.. The AC unit that was running is no-more, both coils have disintegrated... I have another unit (no clue what kind it is because I can't make out any writing on it so I don't even know if it works but wait it gets worse... neither unite has any plugs everything was just wired.. I have a "Dometic ADB Kit Air Conditioner Ceiling Assembly Manual Control 3107206.017".. also with no plug, and I have, well I don't even know what half this stuff is called and I can't even find anyone to come and just LOOK at it, I told them I'd pay cash just to look and tell me.. anyway, I could send you pics of what I have and maybe you could point me in the right direction.. Me ain't no dummy ..LoL.. but I'm also not an A/C guy.
Thanks .. Dragon
Wow....That a lot of questions
@@hillbillyrv I know, I'm sorry but I believe just knowing that the compressor works for sure would be all I really need, after that I'm pretty sure I could handle it. Two sad parts involved here, one is that these lazy arse, cry baby, not wanting to do a damn thing anymore really makes me sick and the other is of course that it's like 96* outside making it, well too hot to be in here.... LoL
@@DragonLord721 All you have to do is determine which wire is the power for the compressor and put 110 volt AC power to it. The inside of the control box lid should have a schematic to aid you.
@@hillbillyrv Hey there, I'm sorry but I guess I was a little confusing in my wording so let me try this .. I have absolutely "no" diagrams, schematics, manufacture names in any way shape or form at all on any piece of material I have at all with the exception of a partial image of a decal on the upper unit (I have a picture I could send you) located next to the access opening to where the capacitors are located but the only numbers that can be seen are in the bottom right of the decal that are 6799A881 or maybe 381 and that's it my friend.
Just so you know, nothing stolen here ..lol.. I bought this old camper a few years back just to put on our property to gut it out and redo to live in (never to be moved again). My parents live in the house and I live in this, I would love to show you the before and after pictures but anyway all a sudden the AC went ca-put and I have just gathered misc. parts over the years.
@@ralphporter6006 When you say the AC just went kuput, what do you mean? Did it quit running or quit cooling? If it quit running and you have good AC voltage at the control box, then you should go ahead and update to the digital control and T-Stat. You will have to have this if you have to buy a new AC anyway, so it is not wasted money. If this is a Dometic AC there is a link in the description of my newer videos where you can buy the controls.
It looked like the freeze sensor is in the center of the coil. I had my coil freeze up and found according to the manufacture it should be installed in the lower left corner. Seems to have solved my problem. What is your experience with the positioning of the sensor and coil freeze ups? Thanks
I have not found that exact placement is not that critical, but if you are having problems with the AC freezing up, I would say moving it might make a slight difference. I have seen them stuck all over the coils and have probably found a hundred of them that either had never been inserted in the coils or had fallen out.
@@hillbillyrv Thank you for your reply. I purchased a new sensor and the directions sow the placement in the lower left. Plan ohm the two in a glass of ice water. See what I find. Thanks again. You are a big help!
@@julianreynolds6864 You are welcome
i think this is what I need. I got this RV from a friend. When the power is turned on (at breaker) the AC turns on and that's it. it stays on. the thermostat control has no effect. Have you experienced that? I have a duo-therm
I have a new video coming out tomorrow morning that addresses your exact problem. How is that for timing?
@@hillbillyrv oh good. meanwhile I did order the new control board. since the compressor and fan work, i figure it's gotta be the board shorted somehow. I was goign to take it out and look for a short or friend component on the board, ,but since it seems others have the relays go bad, it must be a good idea to upgrade. I hope I did the right thing by buying it. Thanks for all your help you are sharing to make our lives easier!
@@surveyguyor8958 You are welcome
@@surveyguyor8958 I hope you ordered it through my amazon link in the description that is in my newer videos.
@@hillbillyrv thats what I think I did. I first went to that amazon link of yours. I hope I did it correctly.
Sorry hard to see the part number can you tell me please I have a friend with an Georgie boy 2003 couch needing 2 thanks
Go the the amazon link in my newer videos. They are in my store.
Does that box have a part number?

What happens if I don’t have a orange comm wire from my box to the thermostat
Pick another color. You should have several to choose from.
Something weird happened to me.. My Dometic AC fan stopped working, so I turned the ac back on and went in the roof to look. Fan spun fine by hand and then I just happened to tap on top of the control box with my screwdriver and the fan instantly started to work. Would this mean I need a new control box? Any help would be greatly appreciated.
All you need is an automatic tapper.........No that's not true. Yes I would say the fan relay is sticking in your control box.
@@hillbillyrv Thank you for answering. I saw you jump the fan to see if it works on your video. I have 2 little dogs that stay in the RV during the day.. Can I possibly disconnect the lo or hi fan wire from the board and hook it directly into the 120 power supply so it can work temporarily?
Think you 🙏
You are welcome.
Hey good easy to follow.. Have two air conditioners and both are on a 89. Winabago Itaska. Will it Still work to change to digital.??? To poor to pay for it.
Shawn martin
If they ain't broke, don't fix them.
The problem therin lies. They are broke and i am not going to wear a bikini !! Thats what the girl says..!
Anyway got to change them both due to a short in isolation switch
Control boards are both bad. As well as the iso. Switch. So can these old things be wired digital.??
Shawn about to be freinds with benafitless.
@@shawnmartin1584 If you had wall thermostats before. Yes
@@hillbillyrv
No these have controls on the unit
I do have a degree in electronics
If you could point me in the right direction for the right parts to change and wire i would appreciate it and i dont want to take up a lot of your time.
Shawn
for 2 ACs, Of course you will need 2 digital control boxes with T-stats and You will need 12 volt + and ground up at the ACs and you will have to run at least 3 wires from control box to T-stat.
I need to also change my new Brisk Air 2 unit to digital. My MFG# is B57915.711CO. I noticed on the box you showed on the video, it had the B57915. Would this be the same unit I need or do I need to also figure out the .711CO part? Thank you for the video!
As long as you are replacing a single zone analog t stat, this part should work. Check out my Amazon link. You will find them there.
@@hillbillyrv thank you! Yes it is a single zone and I will be looking for the link.
@@randykrick3695 cool

I am not familiar with that Dometic model number. I would probably have to call Dometic to confirm which control to use.
@@hillbillyrv Thank you
Fantastic job! Can you help me out with how I hookup this thermostat? I had an older dometic ac like this unit but I only have 4 wires coming from old ac unit to old bi-metal thermostat (red, green, white, blue) and the heavy romex wire (black. White, bye copper). I have a new 15,000 btu dometic penguin ac, furnace, heat pump I just put up on roof and not sure how to hookup because there was no ground on other thermostat for furnace and this new unit does not have a control box its built into unit. Any help would be appreciated. :-)
Hi Ginna. Thanks for watching. I have other videos on this subject too. Have you watched them yet? I think they will answer your questions, if not I will try to help you.
Any suggestions to help me with hooking this new unit up with the older wiring I described?
@@hillbillyrv No I haven't not sure how to go to your other videos or which one if I get to your other videos lol
@@ginnawitters-evans5156 If you subscribe to my channel you can search all of my videos.
@@ginnawitters-evans5156 there are 3 videos about this subject on my youtube channel
I installed this same system in my RV. What a pain in my backside! Thermostat is stupid. I have to set on 80 to 84 degrees to get the temperature I desire to 72 to 78 degrees!! Looses comm every once in a while? Loose power and have to reset it all over again. I never loose 12 volt power. One would think if it has 12 to 13.7 dc volts all the time you would not have to reset the thermostat?? Of course made in China China the main problem!! Would like to find an American made thermostat to work with the heater and air conditioner??
I hear that there might be a solution. A customer the other day just swore by a microair thermostat. Do some research and let me know what you find.
@@hillbillyrv I’ve been looking. Couldn’t find what I need. I just want a thermostat that is accurate and stay connected. It only has three wires to the control box. I don’t need wi-fi or blue tooth. I will not pay $300.00 to $400.00 dollars for a thermostat!!! That’s outrageous cost. I’m old man with a 1995, 29 foot Hitchhiker II. Living on my ranch after 40 years in the Air Force. I came back home to hide from the COVID and try to fix up the ranch after my Dad passed away. 👍🤠
@@mitchelldarnell5334 Just letting you know there are options.
i think your wrong about taking the rv therm off and putting on a res on its a lot cheaper and getter i have done it . but i love the vids
Thanks for watching.
FYI we know you have the knowledge get to the point please everybody likes to hear themselves talk in his videos but you never get to the point
My channel is probably the wrong channel for you.
