The Propane Alarm In Our RV Keeps Going Off

Our Safe-T-Alert for propane keeps beeping red and we cannot smell propane anywhere. Not sure what's causing it to do that. We are brand new camper owners and not sure what to do.

ANSWER: Hi Brenda, unfortunately you do not tell me if you own a brand new or used RV, so I do not know the exact model of propane detector you might have. But, anytime your RV's propane detector goes off, you need to take it seriously as it could be indicating a true propane leak.

In most cases the detector is sensitive enough to detect the propane before you actually smell it, so do not depend on your nose as a second detector. To be on the safe side when the detector goes off the first thing you should do is leave the RV and turn off the RV's propane supply at the main propane tank and see if the alarm ceases after a few minutes. If it does it is a sure sign that your RV has a propane leak and should be leak checked and repaired by a certified RV Technician.

Take a look at the short video below for some more information on RV Propane Detectors and a simple method to quickly test the detector.


One of the key points mentioned in the video is that Propane Detectors and Carbon Monoxide Detectors should be replaced every 5 to 7 years. As also mentioned mentioned in the video Propane and Carbon monoxide detectors have manufacturer dates stamped on the backs of them so you can determine if it is time to replace them.

Another point I should mention here is that Propane is not the only chemical that can set off a Propane Detector.

Listed below are some common items that can set off propane detectors

* Hair Spray

* Febreze

* Some Cooking Sprays

* Some spray on sunscreens

* Dog and Human Farts (if this happens you should always blame it on the dog) :-)

* Some carpet cleaning chemicals

I am sure that there are even more common chemicals that can set a propane detector off.

Propane and Carbon Monoxide detectors also require routine cleaning.

At Least Once a Week You Should

* Check to make sure that the indicator light on the front of the detector is solid green in color.

* Using the soft brush attachment on your Vacuum Cleaner; vacuum off the detector cover.

* Using a clean moist lint free cloth or paper towel wipe off the front of the detector. Dry with a lint free soft cloth.


WARNING: As mentioned earlier Propane Detectors are sensitive to other chemicals, so you should not use any chemicals or solvents directly on or near the detector. If you do it may damage the sensors and/or cause false alarms.

At this point I would have liked to have given you a list of alarm and light codes for your detector and what they all mean, but again these alarm codes vary by detector model and manufacturer.

I should note here that on certain model detectors an intermittent alarm and red light can indicate that the detector is not getting sufficient voltage to operate properly, so you may want to check the voltage on your RV's house batteries especially if this beeping is only occurring when the RV is not plugged into shore power.

Lastly, if this beeping continues, it may be time to replace the detector. If this is the case you may want to consider buying a Dual Detector that Detects both Propane and Carbon Monoxide.

A Dual Detector with a Solenoid may be the right choice for you. The solenoid attaches to the main line leaving your RV's propane tank, so that when the alarm goes off the your main propane tank shuts itself off. These types of detectors are a bit more expensive, but at least you will have the peace of mind that if a propane leak occurs and you are not in the RV; the propane will shut down automatically preventing a possible explosion and fire.

Propane alerts
by: RV Mom

Our alarm keeps going off usually early morning hours. No rhyme or reason. Can this alarm be alerting us That the propane tanks are near empty?

Safe-T-Alert false alarm
by: Anonymous

We have the Flagstaff RV as well. It comes with the safety alert carbon monoxide propane detector. These are super sensitive and hours only alarms at night. But I guess is perhaps the campfire smoke that gets embedded in our clothing sets it off. Because I see other posts about night time alarms which would mean you finished with a night around the campfires. We have replaced the original what they like branded model and got the same results. I believe it may be so sensitive that it picks up the Co from our off-gassing clothes. I am a firefighter in our bunker gear can do the same thing. Just a thought

Randon alarm
by: Anonymous

We were fine with the detector in our Rv for 2 years. Then it started going off at random times. Even turned the propane off and still shrieked. Replaced and was fine for months and then started acting like the old one. We are positive there is no leak of any sort - it has been checked. We had been considering getting rid of our camper but now we see it is a common problem. There has to be a solution to this dilemma. We love camping but this has got to stop.

LP alarm!! Won't quit!!
by: Anonymous

2015 Ice Castle RV edition.. safe T- alarms are going off for the LP! Only goes off at night, usually the middle of the night. We are hooked up to electric, so. It using the battery.. We have had to shut off gas to camper totally for it to go off. What could be causing this?? No stove or range is on?? No furnace going either... any ideas??

Note from RVing Al The fact that the Propane Detector stops going off when you shut off the propane in your RV means that you have a leak in the propane system in your RV. You need to get someone to check your whole propane system to locate and repair the link.

3am alarm without gas
by: Anonymous

I'm joining others in the early alarm complaints. We just bought a used trailer (2004 Pioneer) and dealt with the battery issue while at home. Now camping without gas even on the alarm sounds at 3am (right after turning the fan off). Alarm is cci brand but same issue. There is farting but could that be there cause?

Farts and hairspray-you got that right!
by: Anonymous

Farts and hairspray-you got that right! Turns out the wife had sprayed her hair with dry shampoo just before the detector started screaming at us indicating gas. Opened up the screens and vented. Situation normal. Stress levels normal again. Thanks to the forum for pointing that one out!

Beeping Sound Warning of Very Low Battery
by: Anonymous

Have 2017 Flagstaff RV trailer. An alarm started beeping about every 20 seconds. Checked fire smoke alarm detector and it wasn't that. Checked the carbon monoxide detector which was flashing green and red, and pressed the reset button. The beeping continued. It's 1am and earlier AC and lights shut down, even with generator running, but tv continued.

Got flashlight and went outside to the compartment that holds the butane tanks. There is a switch there to DISCONNECT BATTERY.I pushed the switch in. This ended the beeping. Apparently, a warning that the battery was reaching a critical drain point, something I could do nothing about until places opened the next day where I could buy a charger and connect it into the generator to recharge the battery.

I thought the battery would automatically recharge when I turned generator on and it appeared to do that for about 2 weeks until it started shutting things off. First, with allowing use of one zone not both zones for heating and cooling. Then it eventually shut down cooling AC totally, and started flashing the lights in RV. Eventually, all of the lights dimmed and then went dark totally.

The Alarm is Still Going Off
by: Anonymous

The alarm started going off and will not stop. It is winter, the propane has been shut off and there is no battery, no electricity running to the RV. What is causing this and what can I do?

Propane Deterctor
by: Anonymousloulavender@hotmail.com

I have a 30 ft. Artic fox fifth wheel. For the last few years when I drain the water, and fill it up with the antifreeze, (glucose, I think) the alarm goes off. I do not hear (I'm a Nam Vet) but my wife can hear it clearly off of our deck. This year for the first time, I checked to insure that the propane tanks were turned off., and they were. I also turned on one of the ceiling fans in the area of the kitchen, and the alarm ceased. Then today, the alarm was going off again. At first, a few years ago, I though that the that the winterizing fluid was the cause of the alarm going off, However now I'm not sure. Although this is a 2006 model Artic Cat, we bought it in 2007. I would estimate that we do not have more than about 80 days at most using this unit. Is there anything else we should be checking. Thanking you for any help you can provide.

Location detector

Ours does the low battery warning but doesn't turn off when plugged into shore power does this mean it's gone bad or could it be something else

Ugh we finally had enough!!!
by: Sleep deprived

We keep our main propane tanks off until we need them to help prevent this horrible thing from beeping.. well that doesn't help. Yet again I sit lying awake from fighting the awful noise this thing keeps emitting every few minutes.

It may not be the safest choice we have ever made but after cutting the cords on it, we will be sleeping better. We have a brand new csmper, this shouldn't be happening. Nothing blocking air or even close to it, we have not sprayed anything to set it off and there's no dog

Adding to the 4:00 AM Bandwagon
by: Anonymous

Ours, too, goes off at 4:00 am every few weeks for no reason. It's the Safe-T brand model that's only a year old. It's insanely annoying and we're going to replace it with the cheap-assed First Alert detector that doesn't work in half the reviews I read. I had hoped someone had a solution for this, but apparently others are in the same very tiring boat.

Propane Detector = Dog Farts ***SOLUTION
by: JustPractical

Our propane detector goes off at 3-4am on EVERY camping trip, every night. We finally figured out that it was the dog, (it did not happen when the dog did not go). It would take 2 hours venting the trailer, using fans, swing the door open and closed, to get it finally stop. Sleep ruined...
*****SOLUTION*****: local hardware store has the vent that goes on the roof of a house around pipes (the one that looks like an upside down funnel with a sheet of galv-steel on the bottom. Trimmed that sheet of steel to match the vent-a-hood filter size exactly. Remove the filter from vent-a-hood, insert the trimmed roof vent. Now duct tape a 10' close dryer hose over the funnel of the roof vent. Turn on the vent-a-hood. Now I have an external exhausting hose that is long enough to lay on the floor next to the dog. Now the trailer clears of the dog gas in about 10 mins. In the morning I just put my Dog Fart Remover back in a box and under the sofa for another day.

Check your coach battery voltage
by: Dan from Oregon

Some detectors sound a beep and a red light if they encounter low voltage from your coach batteries. This should be described in the owner's manual (you can probably find it on-line somewhere). For me, it is the first warning I get when our coach batteries are discharging excessively (say from leaving the fridge on DC power when not on shore power) or if the coach batteries are not being properly recharged (circuit breaker, engine alternator connection, etc.).

Does this only happen when you are on house batteries? Does the beep and red light go away when you plug into shore power?

Good luck.
-Dan

Bug Spray
by: Alan Stanley

i applied bug spray on myself one summer while standing right above the sensor. I had to pull the fuse to shut it up (I put the fuse back in a short time later). Never will apply bug spray inside the trailer again!

Blockage on propane detctor
by: Anonymous

We have found if anything is left so that it blocks airflow to the detector it start bleeping. We don't know if that's because it is set to go off for that reason or because blocking the air makes it go off. It just does and if we move the obstruction (including our dog who likes to sit near it) the problem stops. I did think it was dog farts but it can be anything including stuff that does not fart like boxes.

propane alarm
by: Anonymous

Our converter failed and was cooking our battery in our class C. The gasses caused the alarm to go off.
