CountryB Posted December 14, 2019 Share Posted December 14, 2019 My LP gas sensor alarm started to beep. One beep about every 30 or 40 seconds. it is located on the kitchen cabinet baseboard below the gas cook-top. there is no gas leak I can detect. I pushed the reset button and light went green and the beep stopped. I thought that was the end of it - but today it was beeping again. I rest it again. Now what? I had a similar beep on my smoke detector - which was telling me the battery was low and needed to be replaced. Does the LP detector have a (backup) battery in it? It is hard wired to my House batteries. Or is it just telling me the whole unit needs to be replaced (aged out)? I wouldn't be surprised if there was some detector inside it that thinks I have not spent enough money on the coach lately so it's going off telling me to buy something☺️ is it a "Safe-T-Alert model 40-442-P".

Scotty Hutto Posted December 14, 2019 Share Posted December 14, 2019 I recently went through the same thing... had to replace it. About $50-ish to get a new one. Manufacturer says they should be replaced every 5 years. I didn’t know that - I thought they were good for 10 years - until I read the data sheet that came with the new one. When they start beeping randomly, they’ve gone south. Link to comment Share on other sites More sharing options...
RustyTools Posted December 14, 2019 Share Posted December 14, 2019 Could be the sensor is aged-out, but maybe you have a dog (or cat)? Propane and methane are similar in molecular composition and the sensor doesn't differentiate between them. We changed our dog's food, and no more midnite alarms. 1 Link to comment Share on other sites More sharing options...
CountryB Posted December 14, 2019 Author Share Posted December 14, 2019 Okay - I'll order a new one. Ron, LOL, we have dogs but no one has been in the coach for past month. Link to comment Share on other sites More sharing options...

Makes me smile Mike because we once had a dog that could set off the LP alarm by expelling gas! We have also had to replace the LP detector because it aged out. Seem I also remember replacing the CO2 detector for the same reason. Link to comment Share on other sites More sharing options...
Dr4Film Posted December 15, 2019 Share Posted December 15, 2019 Most LPG and CO detectors in RV's have an "end of life" warning beep. At least the ones I have in my coach do. Change it out for a new one that isn't dated too old. Link to comment Share on other sites More sharing options...
johncvandoren@gmail.com Posted December 15, 2019 Share Posted December 15, 2019 These detectors must be replaced 60 months from date of manufacture, regardless of install date. Link to comment Share on other sites More sharing options...
knowknot Posted January 7, 2020 Share Posted January 7, 2020 While on the topic of possibly replacing an LPG detector, has anyone found an LPG detector that had its own battery instead of being wired to the coach or chassis battery? I boondock quite a bit and I am always looking for ways to reduce the load on the batteries. Link to comment Share on other sites More sharing options...

Besides, what is the difference between having your LPG detector using power from your on board battery versus a standalone 12 VDC battery? Either one needs to be charged or changed, just depends on whats more convenient. Plus my guess is that it draws a minuscule amount of power as compared to other non-life threatening items in the coach that could reduce your your parasitic load.

CountryB Posted January 7, 2020 Author Share Posted January 7, 2020 I replaced it with the same make and model. It costs about $50 on Amazon (with next day delivery). Job done. Thanks for all the comments and help. Link to comment Share on other sites More sharing options...

Both detectors were placed in service at the same time and the life span on both are rated at 5 years. Both should be replaced.....Dennis Link to comment Share on other sites More sharing options...
johncvandoren@gmail.com Posted April 5, 2020 Share Posted April 5, 2020 60 months from date of manufacture, not install. And yes, replace all alarms. Link to comment Share on other sites More sharing options...
