Our propane detector started going off about 2 hours ago. We reset it, then it starts again. Opening the front door seems to help. No propane is being used and the tank is turned off. Any suggestions would be appreciated as it would be great to be able to get some sleep tonight.

The one in our motorhome did the same thing. I pulled it off the wall and until hooked it. Had to get a new one to replace it. Ours was about 2 1/2 years old. Our motorhome is a 2016, and our Redwood is a 2012. Both use the same detector. The big box stores and probably most hardware stores sell a combination unit for CO and explosive gas that can be plugged into 120 volts for temporary use until you can get a replacement. I don't know what smoke detector you have, but if it does takes a 9 volt battery, you may as well get a new one with the 10 year lithium battery while you're at the store

These carbon monoxide detectors are sensitive. Some aerosol sprays set them off also. They are also sensitive to low voltage. Double check your house batteries in the front compartment. There should be a 3 amp or similar sized fuse just for the co/lp detector in your fuse side of your distribution panel. Could remove that 3 amp fuse or you could remove the 2 screws holding the CO detector from the cabinet and remove a wire nut or bell cap that is securing the wires together. CO detectors do fail. But low voltage makes them chirp to indicate low voltage.

Low voltage is most likely the culprit. Check your batteries, water level in the batteries & all the connections.
You can pull the detector to check the date on the back, they should be good for 5 years, but ours only lasted about 4, yours is '15 RW, so it's 4+ years old.
The detectors run about $100+ so I'd do the batteries 1st, that'll cost you a couple gallons of distilled water & a hour of your time.

Same as Danny's............I had to replace ours at about 4 years.

If your Detector is in the same place as ours, in the end of the Island. If you pull the Plate Drawer out, you can reach the back side of the detector and remove the inline fuse until you can determine if the problem is cause by low voltage or some other cause.
