Expert Answers about RV Gas Detectors


  • Protechtor Propane Detector Replacement for RV Where Light Stays On
  • Your ProTECHtor is pretty old at this point and if it's constantly showing a red alarm light after resetting and there is no gas leaks then it is bad and would need to be replaced. Typically these need replacing at around 7 years. The Atwood RV Carbon Monoxide and Propane Gas Detector part # AT36681 will be an excellent replacement for the ProTECHtor LP Gas Detector. The Atwood RV Carbon Monoxide and Propane Gas Detector has a seven year life span which is pretty standard.

  • What Does The Flashing Fault Light Mean On An Atwood RV Propane Gas And CO2 Detector
  • If you're getting a fault with your Atwood RV Carbon Monoxide and Propane Gas Detector # AT36681 then I would first ensure that there's no presence of propane and then would cut power to the detector for a few minutes to let it fully power down. Once it's been off for a bit you can reconnect the power, if the fault occurs again then the detector is either at the end of it's lifespan and is telling you so via the fault light or the power supply running to it isn't 12v and you'll need to...

  • Troubleshooting An Atwood ProTECHtor 2000 Series Gas And Carbon Monoxide Detector That Wont Reset
  • If the alarm on your Atwood ProTECHtor 2000 Series will not reset then you either have a leak or the detector itself is faulty and needs to be replaced. The average lifespan for a gas and carbon monoxide detector is 5 years so you most likely just need to replace it. We currently carry the 2-Wire RV Propane Gas and Carbon Monoxide Detector # RS54FR or 3-Wire Propane Gas and Carbon Monoxide Detector for Thor Motorhomes RS94FR that you can replace it with depending on how many wires your...

  • Troubleshooting Atwood RV Carbon Monoxide Detector That Has Blinking Light When Hooked To Batteries
  • Since the Atwood RV Carbon Monoxide and Propane Gas Detector AT36681 you have is not blinking when you are hooked up to shore power, and only when running off the batteries I recommend checking the wiring connections to the battery which could have come loose. If you find that all of the connections are correct then replacing the unit with a new one will be required to make sure it is properly monitoring your trailer from harmful Carbon Monoxide or Propane Gas. Since the AT36681 you have...

  • Troubleshooting Beeping Every 40 Seconds with Atwood RV Carbon Monoxide Detector
  • We've seen this issue before on your Atwood RV Carbon Monoxide and Propane Gas Detector # AT36681 and the beeping every 40 seconds indicates "a fault has been detected that compromises some detector function." What you need to do is use push the Alarm Reset button to attempt to clear the fault. If this does not work, the owner's manual states that "the detector is not functioning properly and must be replaced."

  • Troubleshooting Atwood RV Carbon Monoxide and Propane Detector with Red Light Flashing on Propane
  • The red blinking light on the light of the Atwood RV Carbon Monoxide and Propane Gas Detector AT36681 typically means that the propane sensor is disabled or faulty. Since you've already tried resetting the unit you'll want to make sure you are getting at least 9 volts to the unit. If the unit is getting proper power (~12v), this would indicate the unit is faulty and would need to be replaced. I don't believe the Atwood units are still being made since they were sold to Dometic a few years...

  • Newly Installed RV Safe Gas Detector Doesn't Work on Shore Power
  • This has happened a few times before with the 2-Wire RV Propane Gas and Carbon Monoxide Detector - 12 Volt - Black # RS54FR, where someone replaces their old non-functioning alarm with a new one, but the new alarm appears not to work when the RV is plugged into shore power; but it does work when the RV is powered by the 12v battery. The problem is actually the 12v power converter, which is a more common problem on older RVs. The power converter may appear to work, and will even read a...

  • Troubleshooting the Atwood RV Carbon Monoxide and Propane Gas Detector AT36681
  • It sounds like your Atwood RV Carbon Monoxide and Propane Gas Detector part # AT36681 is hooked up properly and is getting power. The code you hear is like you said a fault code in this case because of the audible tone. I recommend replacing it. The likely issue is corrosion or a short in the detector itself.

  • Atwood Carbon Monoxide And Propane Detector
  • Regarding the carbon monoxide, it's an important reminder that there would be no odor in the case of that leak and consulting a professional would be recommended. This is a fairly common problem and these Atwood RV Carbon Monoxide and Propane Gas Detector # AT36681 do not have a seperate battery inside but sometimes a bad fuse or short can cause this. I contacted Dometic who acquired Atwood and they recommended removing it and replacing this unit as it likely has a short.

  • Troubleshooting 12 Volt CO Detector That Goes Off When 120 Volt Does Not
  • When I hear a complaint about a CO detector going off when there is not likely any CO in the air the first thing I recommend checking is the power going to the unit. On a detector like the 2-Wire RV Propane Gas and Carbon Monoxide Detector # RS54FR the power wires are ran directly to the battery bypassing any 12 volt disconnect switches. This is a safety device that should always see 12 volt power. This may cause the battery to be drained or rodents to find the wire since it has power going...

  • Red Blinking Propane Light On Atwood RV Carbon Monoxide and Propane Gas Detector
  • The red blinking light on the Atwood RV Carbon Monoxide and Propane Gas Detector part # AT36681 under the propane heading means that the propane sensor is disabled or faulty. I recommend doing a hard reset of the unit but if that does not work then make sure you are getting at least 9 volts to the unit. If the light still blinks after the rest and ensuing it has proper power then it will need to be replaced.

  • My CO/Propane Detector Beeps Every Couple Hours In My 2019 Leisure Travel Motor Home
  • On your 2019 LTV Motorhome, the Atwood 31011 (Discontinued) CO/Propane Detector beeping every couple hours while driving could be a couple different things. I would start with checking the battery to make sure it isn't getting too low. If it is low, fully charge it and see if the chirping stops. If your battery is fully charged and it is still chirping then the unit is malfunctioning and should be replaced. I recommend the RVSafe RV Carbon Monoxide and Propane Gas Detector - 12 Volt - White...

  • Troubleshooting No Power Light on Atwood Protechtor for 1997 Carri-Lite Camper
  • If your Atwood Protechtor isn't working then either the fuse is blown, the power wire is damaged, or you need to replace the entire unit. You can easily enough figure out where the power stops by using a circuit tester # PTW2979 along the red power wire (being sure to check before and after the fuse). If you have no power and all of your wiring looks good then you can replace/upgrade your detector to the Atwood RV Carbon Monoxide and Propane Gas Detector # AT36681.

  • Atwood LP Gas and Carbon Monoxide Detector Indicator Lights Flashing Red and Yellow
  • You will most likely need to replace your Atwood carbon monoxide/LP gas detector # AT36681. It has a 7-year lifespan and if it has been in service longer than that it may not function properly. There are several things that the flashing lights could indicate: Power visual indicator flashing means the detector's power supply voltage is too high or too low. Carbon Monoxide indicator flashing means the CO alarm is disabled because the alarm is resetting or stabilizing OR the unit has gone...

  • Troubleshooting Low Propane Pressure to Grill
  • Propane cannot be over-regulated so assuming both regulators are rated the same the output will be the same. It sounds like you may have a leak that is causing you not to get the appropriate amount of pressure to your grill or potentially a faulty regulator. Sometimes propane hoses can get clogged as well but since you mentioned you have a new hose we can likely rule that out. What I recommend is using the Camco Propane Cylinder Gas Gauge and Leak Detector # CAM59023 which will tell you...

  • Using A Gas Water Heater At 6,500 Foot Elevation
  • Correct, at higher elevation gas powered tankless water heaters like the Fogatti # LSB44FR will not perform as expected. Any altitude over 4,000 ft high you will typically see around 4% BTU for every 1,000 ft above 4,000 ft in elevation. With a heating capacity of 41,800 BTU you can expect to see a 10% decrease in heating performance bringing the expected performance to around 37,620 BTU. To be extra safe, I recommend installing the Atwood RV Carbon Monoxide Detector # RS94FR to make sure...

  • Trailer Motion Detector Light Randomly Goes On And Off
  • There could be a couple reasons why your motion detector, like the LED RV Security Light # CE76FR is malfunctioning. One cause could be a short somewhere in the circuitry. In this case, you're going to need to replace the entire sensor, unless you are capable of repairing a shorted circuit board. Alternatively, you may also have a bad bulb or diode, and again, in that case, you will need to replace the entire sensor as well.

  • Can a Propane Hose Get Clogged Up
  • A propane hose can get clogged by debris or organic materials. So it is possible that is why you are not getting any gas through the line. It also could be a faulty regulator, valve, empty tank or a leak somewhere. You might consider a gauge and leak detector such as # CAM59023 to help you monitor the goings-on with the propane.

  • Troubleshooting Low Propane Pressure
  • Typically the situation you are describing is characteristic of a leak in line, a low BTU rating on the regulator, or an empty tank. If you filled your tank recently, and your regulator has the correct BTU rating, then you will want to check your hose lines for any indication of a leak. The wrong regulator would not offer the right amount of pressure for the appliances. If you are still unable to find a leak I recommend you take your trailer to a local qualified trailer service shop...

  • Troubleshooting Propane Supply Problem with Horizontal Tank of 2008 NorthStar Pop Up Camper
  • It does sound like the pigtail is the issue. They often have a backflow preventer on them and it sounds like yours is malfunctioning. I recommend using the Propane Hose with Back Check - Type 1 x 1/4" Male NPT - 20" # 37207-30865. The tank orientation can absolutely be an issue as vertical tanks should never be used horizontally. There are horizontal tanks that should be utilized for your application. If you are using a vertical tank in a horizontal position this could be the issue...
