Do any of you ever have the "Fault" alarm on and if so, what causes it?
Welcome to the forums!
Before you get too far, you need to read the owners manual for your LP gas detector or, if you don't have a manual, see if you can find one online or call the manufacturer. I suspect that a "fault" indication means that the gas detector has failed its internal self-test and is telling you that it's not working right.
If I remember correctly our LP gas detector has four possible states,
- Normal - detector working and not detecting gas - flashing green LED
- Low battery voltage - intermittent beeping and flashing red LED
- Malfunction - intermittent beeping and flashing yellow LED
- ALARM - gas detected - horn blowing continuously (loud enough to wake the dead!) and red LED.
We have seen 3 of these 4 conditions at one time or another - normal, low voltage, and ALARM. If your LP gas detector is detecting gas, it will let you know! (We accidentally left the oven pilot on, but not lit.)
