Atwood RV Gas Detectors - AT36681

  • Carbon Monoxide and Propane
  • White
  • Atwood
  • Indicator Lights

Using fueled appliances in your RV can increase the risk of high levels of propane gas and carbon monoxide. Protect your family from both with one detector. Uses less power, gives early alerts with fewer false alarms, and lasts up to 7 years.


  • Carbon monoxide and propane gas detector alerts you to potentially dangerous levels of gas in your RV
    • Detects levels of CO as low as 30 ppm
    • Detects levels of LP gas as low as 2,000 ppm
  • Fuel-cell sensor gives an earlier alert when CO levels are high
    • Less sensitive to false-alarm triggers than other detectors
  • Test/reset button lets you test the sound and reset to normal after an alarm
  • 4 Indicator lights take out the guesswork
    • Carbon monoxide light goes on during active CO alarm
    • Propane light goes on during active LP gas alarm
    • Power light illuminates if power is low
    • Fault light lights up if maintenance is needed
  • Power conservation mode reserves current draw if your RV power surges or dips
    • Second power wire can be connected to auxiliary 12-volt battery for backup
  • Lasts up to 7 years from the time you first turn the unit on
  • Adapter plate included for flush-mount installation
  • White color
  • ETL tested for residential and RV use
  • CSA certified


  • Wall cutout size: 3-9/16" long x 3-7/16" wide x 1" deep
  • RV voltage: 12 volt DC
  • Current draw: up to 75 mA
  • Alarm intensity: 85 decibels at a distance of 10'
  • 7-Year lifespan starts at first power-up
  • 2-Year limited warranty

Note: Because LP gas is heavier than air, this detector should be installed no more than 18" from the floor so that it can accurately detect the amount of gas in your RV.

The risk of carbon monoxide (CO) poisoning goes up when you use fuel-burning appliances, and propane (LP gas) is usually the first choice of power in RVs. This 2-in-1 alarm gives you early detection, and peace of mind from the possible dangers of both gasses.

Average Customer Rating:  4.7 out of 5 stars   (202 Customer Reviews)

Thought I was upgrading to a higher end detector than what came from factory. Less than a year it did the same thing the stock one did. Would alarm for no reason in the middle of the night. Then eventually went into alarm and would not reset. I disconnected it. Going to look for a better one. The problem is I had to cut a bigger hole to install the Atwood unit.


As a full-time RVer, I rely on companies like etrailer to get the parts I need to make repairs on my RV. The staff have always been friendly and professional. I have yet to return any product I have ordered.
Due diligence is required on the customer to make sure that the correct part is ordered. If you can’t find what you are looking for, call etrailer and they will most likely be able to help!
Now I have to install my parts…..



This product has one function. Detecting an unwanted gas. So far, so good!


Connected unit per manual and unit did not come on. Several lite fixtures and fan not working. Fuses and breakers all functional.

I have gotten in contact with the manufacturer and they have are convinced it just a bad alarm. They are willing to replace the unit for you. Once you receive the replacement, I would love to hear your updated feedback.


Installed as a replacement for the original 2007 unit. While I had to increase the size of the hole in the wall to install, it also reduced the amount of protrusion from the wall compared to the old detector (multi max tool to the rescue). I like the additional CO feature as well as the propane detection capability. Need to keep in mind the detectors in RV's have expiration dates and need replacement to maintain safe operation.


I just received my new replacement unit, and haven't yet installed it, so I cant say if it works or not. I'm sure it does, but I can speak on how great the customer service was on this order. I was well informed through out the entire order process and the status of the order. 5 stars on service. I would have rated the unit 5 stars if it would have been an option for the color to be Black or White. All my finishes in my camper are Black, so having this available in Black would have been nice. But this isn't Etrailer's fault, the unit doesn't come in Black anymore from what I have seen. I'm really picky on things matching, but that's just me. Plan to install it this weekend.

No issues yet. Installed it a few months ago. Hopefully it will last, and hopefully they will come out with a Black colored model so it will match the interior finishes.

Went camping in March 2023. All good. No more false alarms or beeps in the middle of the night! Seems to be working well.


Dead on arrival. The unit fault light on solid and the rest are blinking. User guide says unit is bad. Contacted etrailer, and they just sent me Dometic's number, which was incorrect and I had to look that up. I'll update if Dometic steps up and send a new unit.


Works great! Since the unit was exactly the the same as our original unit it mounted in the same location and the wiring was simple being just as the original unit. Buy with confidence at Etrailer!


Thanks so much!we were going camping when the co monitor stop working look everywhere for a new one. Sold out. Everyone would say. Called etrailer. Problem solved thanks so much for being helpful.


This was a direct replacement for one that came with the RV. As an RV Inspector, I knew it was at end of life even before it beeped, as usual was great and timely on getting my new one and it works flawlessly.


This was a replacement for the Atwood detector #33535E in our Cirrus truck camper. The alarm started giving random chirps when the temperature dropped at night and it was about 7 years old so needed to replace it. This model fit perfectly in the cutout. The dimensions and installation info here on the ETrailer site helped us order the right model and it was easy to plug and play. I like the Phillips screw heads.


I installed it and it works fine. My only issue is that according to the date of manufacture, the detector was already 21 months old upon delivery. With a life expectancy of 7 years, 25% of the two sensors lives are already gone once I bought the detector. It wouldn't be such a big deal if they were cheap, but these things are expensive.


I cannot yet comment on the performance. This detector replaced an on-wall LP Gas detector. I like that it detects both propane and CO.

I had a small 50-cent piece size hole in my wall, and had to enlarge it to 3" x 3" as this is an in-wall mount. Once mounted, it rises only 1/4" from the wall. I used a hacksaw blade to saw the hole for the mounting. Measure twice, cut once.

If you have two power sources, such as battery and another, it has two power inputs. You may also wire the two inputs to one source, as I did. My batteries are on solar charge.

When you first connect it, the light blips, but if you hit the test / reset button, it clears them all and leaves a small, green, LED power button.

I have yet to test this, but hope to do so soon.
