Atwood RV Gas Detectors - AT36681

  • Atwood
  • RV Carbon Monoxide and Propane Detector
  • White
  • 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.

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.


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.


Works good. Same as oem. A bit pricey,but; i found it like always at etrailer. Thank you etrailer.


It quit working already - beeps all the time just like the 5 year old one we replaced!

This has a 2 year warranty I will have customer service reach out to you.

This replaced another brand that was faulty. Easy to install and it continues to work perfectly.

Good product. This replaced an old detector that stopped working. It was easy to wire from the existing wire and seems to work perfectly. I highly recommend this detector.

Junk. Bought 2 neither one worked more than a week. Threw them away.

The units are meant to last up to seven years from when they are first turned on and do have a two year limited warranty,

Easy to install, works great, no issues and will recommend this monitor if you are needing one!!!


Easy to install, works with both single or dual power supplies.
Used in a Motor Home mounted 1" off the floor. The unit alerts me to propane leaks and Carbon monoxide inside the Motor Home. only needing one unit, cost savings.

The unit is working well I run a test on it every month. The only maintenance this unit requires is vacuuming the front of it, and the openings usually about once a month when I test. The only notable item is that with Covid-19, I use a Lysol spray every so often. This spray will set the unit off. I have found that it will minimize this if you turn the fan on one of your air conditioners. I would highly recommend this unit to anyone looking to replace their older one or upgrade.

Worked easy to install


Shipping was pretty quick. Price was ok. Item appears to be a little old. Mfg date on the LP and CO detector I received is Aug 10 2015. Will this mean that the expected lifetime of 7 years only give me 3 years before I have to replace it?

According to the manufacturer the 7 year lifespan of your Atwood Carbon Monoxide and Propane Gas detector is an in-use lifespan, regardless of the manufacture date, or how long it may have been on a shelf in our warehouse or the manufacturers warehouse.

Thanks for getting back to me. That is great to hear.

bought this to replace original in motorhome that had reached 60 month end of life.
AT36681 has 7 year lifespan.

Working fine, no problems

This is the exact replacement for the one that came in my Chalet LTW Folding trailer.
Needless to say, it was straight forward to install once I got the old one out. The manual says that the unit is good for 7 years after it's activated (powered on) so while the manufacturing date on the back may have relevance, the unit doesn't care. Make sure you record the date of installation. There is a stick that comes in the package but when I attempted to peel it of, a thin layer of paper stuck to the adhesive so it wouldn't stick. Not a biggie, just wrote on the manual.


Easy installation and no problems. I would definitely recommend this detector.


Our Atwood RV carbon monoxide and propane gas detector quit working in our 2013 Redwood. I ordered a replacement and found exactly what I needed at The only difference is the unit was white instead of my black but that's totally immaterial. We easily put it in and it's now working as it should. Shipping was fast too. Thank you!


Seems to work as advertised. We had one false alarm whey we used Lysol disinfectant spray near the detector so I guess it is working?


The carbon monoxide and propane detector came on time as expected. Was easy to install and worked. It went in our motorhome the one that was in it was black and this one is white but no problem with that color thanks etrailer.


Excellent product. I bought this to replace the 5 year old propane gas detector in our travel trailer. I appreciate that this detector is for both CO and propane, and that it's projected useful life is 7 years.


This was a replay of the original detector in our Motorhome. It was a perfect fit and works great


Great product! I couldn't figure out why my old At36681 was chirping, until I read the manual and found out it had reached the 7 year age limit. Ordered replacement, and sent it to my door in record time. Really impressed with!


Great, professional, timely customer service! Really happy to have a dual purpose, easy to install detector - thanks!


It did not last more than two weeks. I n our third week out camping, it went out. It is currently unplugged.

Thank you for your review. I am surprised that you are having trouble with this product as it is supposed to last at least 7 years. Wiring this up to your 12-volt battery for backup is probably a good idea while camping just so that it does not slip into power conservation mode. This product has a 2-year warranty.
-- Etrailer Expert Sierra K - 03/02/2021


Haven't installed this yet but looks exactly like the OEM one I am replacing in our Pleasure-Way camper van, except it is white not black. Atwood no longer makes it in black. Great product for a good price and low shipping cost. Always glad to do business with E-Trailer.


With the original protector lp detector outdated. Decided to try this one. Fit on cutout was a little bit wider than the original detector which is better than it being smaller. Adding in the Co detector in with it makes it that much more of a conveneince.


Exactly replacement part that I need. Fast shipping right to my house. Customer support provided videos on installation. Yeah would definitely use again for any trailer parts needed. I highly recommend.


the detector is an Item that one hopes never have go. The installation was easy enough. Had to modify the opening and the original detector was circular in shape. Seems to work well, but haven't gone on any RV trips in 2020 due to Covid-19
