Dometic Thermostat Replacement - Step-By-Step

[@louellen7271]

Extremely clear directions! Too bad everyone doesn't explain things so well.

[@territ8837]

I've learned that the gentle touch on the buttons is all that is needed. I read that putting pressure on those buttons by pressing instead of tapping will wear down the touch pads. The only problem I've had is accidentally brushing up against the key pad and unintentionally changing a setting. It is nice to know that changing the thermostat out is so easy. Thanks for all your instruction videos!

[@JohnMarucci]

Thanks Terri! Fully agree that you need to be gentle with the touch buttons or the pads behind the faceplate will wear down causing issues.

[@jim6378]

Super clear instructions. This was easy to replace. Thanks!

[@JohnMarucci]

Glad it helped!

[@ricktaylor6373]

I’ve the same in my 2021 motorhome John . That thermostat requires a gentle touch per se. Seen some on KZbin somebody put in place of a dometic on a toy hauler but had all the “fancy “ options on it, Bluetooth etc. there’s but two of us. So no need to upgrade beyond the dometic thermostat. They’ve some extra optional thermostats out there that you’ve probably seen as I but for two people we don’t need the extra features. Really like watching your videos . Thanks a bunch . Will be looking for the next one you get out here.

[@JohnMarucci]

Rick, thanks for the comment. The thermostat really does require a light touch. I learned this the hard way on a longer trip but haven't had issues with this model since then. The only problem that seems endemic to this unit is with the low fan setting. Sometimes if I want the low fan on all night with the A/C kicking on occasionally, the fan will go off after the A/C cycles. If I use high fan, the fan will stay on. Other than this, It seems to work well. Thanks again!

[@garymadison7049]

Similar questions. Would you recommend any other brand of thermostat? Or is the new Dometic an improvement? I now have domestic thermostat, furnace and fridge in my 2022 unit. Thanks for your content. I find it very helpful.

[@beehappy1002]

Thank you for the clear instructions. My thermostat is malfunctioning, and this quick replacement will probably correct the problem.

[@JohnMarucci]

Glad it helped!

[@atkinsonjuan2279]

What was the problem you were having....my problem is once it gets to the selected temperature it cuts off....like it should...but wont come back on....i have to turn it off and start it from off...again.... Also did changing out the thermostat resolve your issue.?.

[@davidbeuke6822]

Thanks for your help. What is the item above your thermostat?

[@JohnMarucci]

A humidity gage attached using a magnetic command strip. Here is a link to the product on my Amazon store: amzn.to/4ejHpcC

Thanks john! Having issues with our 2020 keystone outback thermostat. Going to dig in and see if this fixes it. Subscribed ❤

[@thearmoniaband9189]

Thank you for a great video. May I ask why you had to replace your thermostat? Thank you

[@JohnMarucci]

The pads on my faceplate wore down so that the unit was not working properly. There was no way to order just a faceplate, so I replaced the entire unit. Thanks!

[@housesOTR]

Oh, John, John, John. What we do without having to deal with our heaters? Thank you for another great video.

[@JohnMarucci]

Glad the video was helpful.

[@CuriousinNY]

Hi John, excellent step by step video. I have a couple of questions that I am hoping you or someone else can answer. I don’t have a digital thermostat but would like to install one. Question 1. Will my furnace work if I go from manual to digital? Question 2. My AC unit is also manual in that you walk up to the ceiling unit and you turn the dial to turn it on and then it runs continuously until you manually turn it off. When I replace the thermostat with a digital one, what do I need to do/know about in order to get my AC to work with this thermostat too. I look forward to hearing back from you. Keep up the amazing job you do with your videos!

[@JohnMarucci]

Unfortunately, I can't speak to if a digital thermostat will work as a replacement for your non-digital one. You likely will need to speak with a mobile RV tech or a local RV dealer for better advice. There likely are also specific KZbin videos on the subject, I just have never done this change and can't speak to it.

[@wolfstar_productions]

Did this... but the new themo is still doing what the old one did. If I turn on the furnace, the A/C kicks on, even when I have the AC temperature set to max. Any ideas folks?

[@CarenHass]

Thank you for the trouble shoot work for us great and we could do our selves was nice. God Bless !

[@JohnMarucci]

Glad the video was helpful!

[@joycemenges4769]

Can I assume that instead of pulling the fuse, having no shore power and having shut off the battery would accomplish the same thing?

[@JohnMarucci]

It is 12volt so make sure your battery is disconnected at the very least if you don’t pull the fuse.

[@CarolynBuck-o7n]

I am trying to figure out something. I had my single zone thermostat replaced but I have a feeling that there may be issues with the replacement. I was charged nearly double by the repair shop for the part. and now that I am at home and can look up reviews, it seems like the one is not well reviewed. Dometic3316410.012 I want to figure out if this is a part that is discontinued, is there a way to do that? How long does it take to replace a thermostat, a single zone? Which unit did you have trouble with? Hope you see this post. Thank you.

[@JohnMarucci]

I see Amazon and eTrailer both have the replacement unit. My video shows how to do the replacement and it only took about 20 minutes. Here is the link to the replacement: www.etrailer.com/question-665551.html?srsltid=AfmBOooScBDrGPQLlGKkweRppEi6BpEpnaw41ciRrh1DeOeYtDj8V_FE

[@MAGA-qy6fg]

How do you check to know if the thermostat is operational? I swapped out plates and the rear one still didn't work (light up).

[@JohnMarucci]

Can you check to ensure you have power getting to the unit?

[@knuckleheads1929]

Any suggestions to help a system that keeps flipping itself to heat .

[@JohnMarucci]

Have you tried pulling the faceplate to do a reset? If not, gently pull the faceplate and wait about 20 seconds and put it back on. It should reset the unit.

[@knuckleheads1929]

@JohnMarucci yes I tried the reset and leaving the face plate off it just decided it wanted to have a mind of its own. I replaced it today and it seems to have worked . Wanted to say thank you for the video you put out on how to replace the thermostat I was reading a lot of conflicting things online your video made it look easy and definitely helped me get it done quickly. And just incase anyone else is reading this before I replaced the wall unit I called dometic and chatted about the issue they sent me a free replacement faceplate (which I've read often resolves this issue ) but mine seemed to be beyond this point because as stated it was changing settings with out the face plate installed.

[@MAGA-qy6fg]

I swapped out thermostats and I'm not getting power to the thermostat. I'm ruling out anything being wrong with the AC unit. I have to figure how to get to the wiring for this now.

[@JohnMarucci]

Were you able to find the issue?

[@MAGA-qy6fg]

@@JohnMarucci sure did. Squires got into the AC unit and chewed through every wire up there. We called a tech in and we decided to replace the entire AC until. Now, I'm hunting squirrels. Thanks for checking back in.

[@JohnMarucci]

Wow! That frustrating with the squirrels. If it is a Dometic, the Dometic Evolution model has a great replacement A/C for me.

[@ColtonsDad1]

Why did you go with the same thermostat if they are so prone to issues?

[@JohnMarucci]

It was a matter of cost and availability at the time when mine broke down on the road. The one I replaced it with hasn’t had any issues to date.

[@davidclark7347]

​@@JohnMarucciThank you for the response. I have the same Dometic thermostat in mine and I just received my new MicroAir thermostat to replace it. I am looking forward to getting it installed and set up.

[@davidlogan7216]

Thanks for the info. I am a new subscriber. What was the issue with your furnace? We were camping in Ri in early April, and with temperatures dipping into the 30s overnight, we needed our furnace. However, while the blower started, it failed to ignite. We dropped it at a service center and they duplicated the problem 2X then it seemed to have cured itself. BTW, we have a 2019 Keystone Passport with what appears to be the same furnace and definitely the same thermostat.

[@JohnMarucci]

David, here is a link to my video on the furnace issue: kzbin.info/www/bejne/sF7dkJxumcmsnaM

[@fredpuchany9551]

What causes my fan to come on after it shows "off" on the display screen? on the display

[@JohnMarucci]

Not at all sure. If the display is showing off the fan shouldn't come on. You may want to pull the faceplate and put it back on to reset the unit.

[@fredpuchany9551]

Thank you sir!

[@bryans73663]

Is it possible to replace the dometic thermostat with a better thermostat from another company?

[@JohnMarucci]

It is but I have not done it myself. There is a comment somewhere below this video or the other one on how to run the Dometic thermostat where a viewer did just this.

[@JohnMarucci]

The viewer said they replaced with a Micro Air thermostat and that it had the same connections.

[@clintwarren1187]

I want ti do the same, I do not like the capacitive buttons.

[@ralphp3057]

Good Video! Is this another China built product?I don’t have this type in my RV . It’s good to be a handyman with owning certain built RV’s I guess? 🤔Thanks for sharing the info!

[@JohnMarucci]

I didn't see the manufacturing location, but many Dometic components are made in China as are many other brands used in RVs. It is good to be able to tackle simple jobs like this if you own an RV. All the best!

[@rvfamilylife]

This thermostat drives me nuts too. We don't even leave the face plate on anymore. We just touch the little brass ends to make everything work.

[@JohnMarucci]

It can be a frustrating unit. It amazes me that simple push buttons can be replaced by something that doesn’t work well.

[@ralphp3057]

Wouldn’t it just be easy to replace it ?!They can’t cost that much ?🤷🏼‍♂️ But , what do I know. Lol

[@rvfamilylife]

@@ralphp3057 about $250 to replace with an upgrade. But the upgrade works a lot better and. Adds control from your phone

[@ralphp3057]

@@rvfamilylife How much for not connected to your dumb phone! Just kidding.😁

[@MAGA-qy6fg]

Does that work?

[@JohnMarucci]

Take a look at the bottom of this doc. It has the thermostat's error messages. Feel free to download it. I would remove the faceplate, wait 20 seconds and put the faceplate back on to reset the unit. johnmarucci.com/wp-content/uploads/2022/05/Dometic-Thermostat-Guide-2.pdf

[@Robyrob7771]

Absolutely hate this thermostat. I have been wanting to change it out with something a little more reliable and user friendly.

[@JohnMarucci]

It is way too finicky requiring an extremely light touch to not damage the foam behind each button. Totally counterintuitive to using buttons. Really bad design.

[@30forward]

Will any household thermostat work?
