Propane Alarm keeps going off

Anyone have an issue with their propane alarm consistently going off? There is no propane attached but the alarm keeps firing...

Any tips would be greatly appreciated!

Alarm

Hello, most of the propane alarms have a expiration date of about 5 -7 years. It should be on a tag inside your alarm. That's probably why yours keeps going off. Hope this helps

The CO/Propane will alarm if the battery voltage gets too low as an indication that the alarm is not capable of functioning properly. The trigger point is a fairly low number. If the alarm is due to a low battery, you need to address it as it will eventually damage the battery. Are you using it or is it sitting between trips when this happens?

Thx for the tip —- the place where we store the unit has full hookups... so it’s plugged into electricity. Don’t believe it would be a battery issue.

Great tip - thank you ... I will check to see if that is it. Do you know if it’s difficult to replace the propane alarm?

They are super easy to replace. You can find the exact replacement on Amazon. Take out the two screws that hold it in the wall. Disconnect the two wires. Attach the new one and screw it back in place. Three minute job.

Doesn't matter if it's plugged in. The battery can still be low and set off the propane alarm. (It happened to us.)

IPA, coffee and inflatable beds set mine off. These things are crap.

Unhooked mine.

I turn off propane at tanks at night.

Bought a carbon monoxide detector at Walmart. Has never gone off yet. In bedroom area.

You need to get out the book and read all the things that will set off the alarm. I had to replace mine also. But I read the book and Oh MY, I think even a pair of smelly sox will set it off.

All the good tips ring true. Mine has gone off when hooked to power when in fact the battery voltage was low. Expiration date is a consideration. Spraying non-stick cooking spray and Fabreeze has set it off. For the most part, if all of the above are not factors, disconnect it at the source, allow some time, reconnect and then wait for it to recycle per the manufacturer.

Carbon Monoxide detector is NOT the same detector as the propane detector, You need both working in an RV.

Carbon monoxide detector and propane detector monitor two totally different things. If you removed the propane alarm and/or disconnected it and did not replace it, better hope no one inadvertently opens a burner valve on your stove. Smallest spark can cause fire or explosion depending on the concentration of propane.

Keep in mind that it is not a PROPANE detector. It is a FLAMMABLE GAS detector. There are a number of gasses that will set it off, even one of those fist sized vaping machines people use to think their not smoking anymore can set them off. Read the manual, check it out.

I replaced my combination propane /co alarm with a propane only. Then replaced ceiling smoke detector with a combination smoke/co detector. Saved over $1000 buying on line over dealer.

Had a 2015 Georgetown. CO detector went off in middle of night. Unbelievably, after getting it out of the wall I found that it was hardwired, so the only way to stop it was to cut the wires! Investigated and found no problem. Replaced it by purchasing a new MH!

Unfortunately, these never last the 3-5 years that they should. I normally get 2 years out of them. You can try to fix by blowing out w/ can air, being at floor level they catch dust. You can take the part number off yours and find it on Amazon for around $60, much less than the RV shops get. There are 2 models w/ slightly different sizes. It is 2 screws and 2 wire nuts to replace.

All I can say after 2 propane/Co detectors went south on us after 3 years each (the first detector was 2 years old when the unit was built) and got ZERO help from the manufacture (MTI) other then "we only warranty it for one year" and "it must be low voltage".... well not if it's at 13.7 volts consistently, I finally bought a First Alert residential, 110 volt propane /co detector with battery backup.
We are on "shore power" 99% of the time so I'm comfortable with that and the detector is plugged in at in outlet that happens to be the same mounted height the RV detector. No issues since.
