I can't figure out a beeping noise

[holstein13]

About once an hour I hear a single beep coming from the front of my coach. It's a 2014/15 Newmar King Aire.

The beep is coming from the ****pit or generator bay in front of the ****pit. I don't know if it's the generator, Silverleaf system, triptek, GPS or some other system but I'd love to figure this out. Unfortunately, I'm never in the right position when it beeps to determine the exact source.

Any ideas?

Update on edit: The beep lasts for about 1 second and reoccurs every hour and 3 minutes. It is definitely not the refrigerator, not the ceiling smoke detector and not the Generator autostart. No awnings are deployed.

Update #2: It only beeps when the sun is shining and I am plugged into shore power. I'm guessing that it could be a beep that alerts me that the solar controller has finished charging the batteries. Since I'm plugged in, the batteries actually do get fully charged and the solar controller beeps to alert me. This is just a guess.

Update #3: I had a tech in my motorhome when the beep went off. He immediately said it was the Battery Isolation Manager. The other tech agreed and so they replaced the BIM. So far so good. I haven't heard the beep.

My tire pressure monitoring will beep like this when it wakes up from sleep mode. Not sure if you have TPMS. A fault may cause a warning beep.

ok here's what you need to do
you need to find the remote control or the controlled for the item -----and set it to be more frequently :W

You say it beeps every one hour and three minutes- so obviously its going to take you a number of hours or days to figure this out .
so get the remote control out or get the ------you know controller for whatever and program annoying beep to beep..ONCE A minute then you can track it down.....:B

Seriously......if this is still going on.and exact time every time.....it is something monitoring the status of something.
Turn off AC POWER..IE unplug...
If still does it, unhook all batteries

If still does it ..then something small.wiith own power.

Sorry I was of no help....but you could get a beer, slide out the tray and lounge there at the top of the hour...crude, but very effective...Nice coach by the way, if you are ever here at the OBX would love to take a look see.

Propane detector and CO detector. They are hard wired in. The sound echoes thru out the MH very hard to figure out where it is coming from.
Especially if it's the propane one near the floor.

Been there did that. Embarrassed to say it took me over a week to track it down.

Those 2 hard wired detectors will beep if there is even the slightest low voltage detected. It is a built in feature on these detectors for your safety.

My coach battery was on it's way out.

Do you have your auto gen start on?...perhaps there is a module there checking something and it beeping upon a condition check..just a guess

Here's where I stand. I cleared the generator from a yellow status to a green status and it beeped at 6:05. So I then disabled the autostart for the exerciser and the battery charger and that didn't help either. It beeped again at 7:08. So now, I've disabled the autostart for the air temperature. That's the last thing to disable. On the display, I went from yellow to green when I cleared the status, then to blue when I disabled the autostart exercise / charger, and now I'm at grey with everything disabled. I'm still crossing my fingers.

Darn it. 8:12 and it went off again. Any other suggestions?

Thanks janstey58. It's a good suggestion, but the fridge sounds an alarm continuously when I leave it either fully open or partially open. The loud fridge alarm does not cease until I close the door completely. In fact, I've often been surprised when the fridge door alarm goes off and the door looks closed only to discover that it was ajar.

I just heard my offending beep at 6:05 coming from the cockpit again and I turned off the genset autostart so hopefully, I won't hear it at 7:05. I'm keeping my fingers crossed.

You can buy tiny beepers that beep once every hour or so. Impossible to find, but they'll drive you nuts.

Where do I get them. So many people, so little time.

Maybe a very slow bomb! Just a thought!

[wrgrs50s]

Just shootin in the dark, an indoor outdoor thermometer with a low battery maybe?

Your best bet may be as previously suggested, to kill all 110v power and wait. If you still hear it, disconnect all 12v power. If you still hear it, go to an ear doctor? Just kidding !!!

NONE of those are that slow,, I have no idea what would be that slow If it was once every few minutes then the Awning alarm or smoke/gas/CO detectors would apply, but once an hour, more like 10-20 times per hour.

Vehicle alarm system perhaps.. I simply do not know.

unless you put a clock to it it can seem like an hour but may be much less.

to the OP: trip all of your AC breakers and kill the DC if you can. if the noise stops start flipping breakers until the noise resumes.

Have you checked you smoke detector?

That's a great suggestion. I just checked it and NO, unfortunately, that's not the cause. The smoke detector "chirps" when I put in a weak battery. The beep I'm hearing is softer and more remote. But you prompted me to buy some batteries for daylight savings time coming up.

is your fridge door open?

[Teacher_s_Pet]

Have a kitchen/grill count-down timer that will "beep" occasionally if left on. Use it to remind me when flushing the tanks, don't ask why. I have had to track it down before when it "beeped', evidently I didn't leave it on the last time since I haven't heard it and don't know where it is.

I dont know if you have a Norcold Fridge, but ours will quietly beep and show DR on the display if the door is slightly ajar on occasion
