I went out and bought a AA battery powered CO detector with a digital readout for peace of mind. It always reads 0 when the built in one goes off so I know the CO levels are safe.
If it continues next year, I'll start looking for a replacement propane detector and disconnect the built in one. Hopefully someone will identify the problem before then.
I also installed a battery powered CO detector with a digital readout. I've searched for a battery powered LP detector but the ones I found have battery backup, and they state the backup battery is only good for about 20 hours. That implies to me that the LP detector requires way more power than dry cell batteries can furnish, so maybe a battery-only powered LP detector does not exist. (There are industrial hand-held units but they are typically recharged periodically.)
If anyone finds a battery powered LP detector with a digital readout and reasonable battery life, please post it. I'd sure like to get something better than the one that is installed now.
