Alarm

I have an alarm on my 2017 Forester that keeps going off. Propane tank is full, all other tanks are empty, fridge is working and I changed the battery in the smoke alarm. No luck. Any idea on how to reset or turn off the alarm, it sounds like it is coming from the e fridge area.

Three gases are sensed in an RV:
Smoke:The smoke alarm is always mounted on the ceiling since smoke rises.
Propane: The propane detector is always mounted at floor level since propane is heavier than air.
Carbon Monoxide (CO): Usually the CO detector is combined into one of the two detectors above.

The smoke (and maybe CO) detector usually uses a battery, often the 9-volt units with two snaps on the top.

The propane detector draws a lot of current and runs off the house battery. There are three reasons why it could beep:
  1. It's sensing propane (or dog farts or something else)
  2. The house battery is low (very common)
  3. Its internal timer has expired and it wants you to replace it.
Usually each of these has a different beep pattern or LED-flash pattern. If you don't have the manual in all the stuff that came with the motorhome, you could lift it off its mount and read the instructions that are often printed on the back side.

The fridge, if set on gas, and the flame does not light or goes out, will alarm depending on the model. Norcold?

Itís a single beep Every minute or so. I thought it could be the propane since I ran the tank empty but I just filled it up. Battery is showing 13v. Might have to try and locate the propane monitor. Thanks!

The fridge is set to auto and running on power. I did have to reset it when I ran out of propane. Not sure if the brand but I believe it has electric ignition. Will look that up too. Thanks

It could also be that the propane detector needs to be replaced. Yours is getting to the end of its useful life and a single beep every minute or so usually means that it's failing.
They are usually near the floor near the refrigerator.

The CO/Propane detector has a 5 yr life span from the mfg date. After that it will beep to indicate it is out of date. Pull it and check the date printed on the back. Be careful not to short the wires or lose them in the wall.

The fridge will only alarm once. Iíd go with the flammable gas detector.

Most likely the CO/Propane detector. In a 2017 model it should be right at it's end of life. Apparently there is an internal clock that when power is first applied, starts to count down. When it hits so many hours, it's time to replace it. You cannot reset that alarm (made to be that way for safety). They are about $65'ish on Amazon for the more common models.

Any one know where the propane alarm is located on a 2861ds? I can not find it. Only place I have not looked is the sink cabinet that is not accessible when the slide is closed
