Atwood propane co detector chirps

[racefan]

2018 Thor Freedom Elite. My Atwood propane CO detector chirps every hour on the hour only while we’re driving. It won’t do it if we’re stopped. It’s hardwired so it’s not a dead battery issue. The mfg date is 1/5/2015. The manual says a 7 year life from when it’s put into service so that should be a 2025 replacement date. Anyone else have this chirping issue?

Low battery will make it happen all the time

Check your coach batteries! The CO/LP detector is wired directly to the coach batteries, once you're plugged into shore power the converter is helping with 12 volt power, but once unplugged driving your alternator probably can't maintain the battery charge then the detector beeps.

Let’s see. 2015 plus 7 = 2022. Hmmm….. Maybe time to replace. Is it your CO2 detector down by the floor? Or your smoke detector up on the ceiling?

The Atwood manual says a 7 year life from when it’s “put into service” that should be a replace date of 2025. It’s the propane/CO by the floor.

House batteries are new but I’ll check them when unplugged from shore power and then while my wife is driving to see if they are getting a good charge.

Just FYI!
It's a CO (carbon monoxide) detector not CO2 (carbon dioxide).
Also there should be a date on the detector, maybe on the back, which is typically when the 7 year life span begins. How does that detector know when the rv was sold? If the rv was ever powered up or batteries installed while it sat on the dealers lot for apparently 2-3 years the detector was actively working, it's time for a replacement.

When in Doubt..Replace 'Em!

For about 69 dollars for a dual detector it's yor life, better to replace. But still check your batteries without shore power and see if the batteries under load are okay
