I recently left the MH parked beside our S&B and unplugged it while we were out of the area.

While gone, a friend called to say there was beeping coming from inside the rig.

When we got home, I heard the "beeping". and thought it came from the smoke alarm.

Shortly after changing the battery, the beeping started again. Thinking it was a bad battery, I replaced it again.

Beeping continued without the battery in place and I found it  coming from the propane detector.

My question is, will this stop on its own or is the detector due to be replaced.

The rig is a little more than a year old.

Thanks for the info.

Appreciate the info and I 'll look for the switches you mentioned.

But it still doesn't answer the question if the propane sensor 

 needs to be replaced to stop it from beeping.

Propane detectors, being close to the ground can be sensitive to dust, dirt and pet hair  After assuring you do not have a propane leak, remove the detector.  It will have two or three wires attached to it.  Vacuum or use use an air can and try to clear any hair or dust that may have gotten into the detector.  This may clear the alarm.  Some detectors are wired to a solenoid shutoff valve which may need to be reset at the valve or if the propane tank shutoff valve was opened, the solenoid may reset when shutting off the propane tank valve.  If you do have to replace the detector, shop around there can be a wide variety of prices for the same model detector.

We had an issue with our sensor. After you check for leaks you may find the sensor has reached its useful life. They do have a time replacement recommendation. We were unable to find one that was compatible with our shut- off solenoid. Insure you purchase one that is will work with your existing solenoid.Our replacement system included both a new senor and matching solenoid valve.They are easy to replace with basic electrical and plumbing skills
