Wierdest sound inside TT

Ok,
My TT is parked in driveway. Sea level-ish. Battery disconnected. Level via Anderson wedges. Plugged into dedicated 30amp from house fuse box.

Twice now, a week apart I hear a high pitched sound coming from inside (best way I can describe sound is like a cicada-we don't have them here in So cal).

First time I went up to the fridge (off-empty-latched open) opened the door and the sound suddenly stopped.
2nd time I heared it out open slide window, went in and it immediately stopped as I entered door (vibration).

Is this a bug under the fridge)making a loud noise(if never heard before in these parts)?

Can some compressor-ish thing from the fridge be the culprit (even tho it's been off for weeks)?

Can the fuse box/electrical make a noise anything like this? ( I know the water heater whine at high alt sounds like- it's not that)

We are planning a big trip soon n want to be ship-shape.
If something was leaking it wouldn't stop just be me entering- and there no smell of gas- n I've 2 extra Carbon M meters besides built in one- all fine.

Sorry for being paranoid- just want to ask if anyone has experienced anything remotely like this.

I get a high pitched noise that comes from my electrical panel and the sound will change louder/softer as I turn things on/off. Not sure what it is but i had thought it was the fan in the panel but took apart and still hear noise when fans not running. Thinking iím going to need to eventually change out electric panel but not sure how entailed it could be.

I know the high pitched whine sound. we get it at high alts n it's the electric water heater.
This sounds like high pressure gas leaking making a whistling sound. Could it be some non-propane gas-freon etc leaking from fridge somehow? But it's off and why would it stop the second I step into TT.
There's no carbon M monitors beeping either

Maybe it's a freak unique sounding cricket under the fridge bent on driving me crazy-haha!

Since you are plugged in and the battery is disconnected it may be something in the electrical center. Try connecting your battery and see if it goes away. If nothing else you are charging/maintaining your battery.

I have an inverter in my truck that makes a noise like you describe when I don't have a load connected or when the voltage drops down. My theory is that something in your electrical system is seeking more power periodically than your converter can put out and it results in the noise you describe.

The fact it seems to go away when you move inside the trailer may just be coincidence.

We hear the same noise in our camper. Ours always occurs when we turn the lights out at night. Our noise is coming from the inverter (electrical panel). Ours always dies out and goes away after a minute or two. Has been doing it since we bought the unit in 2014. Never has caused a problem, but I have always wondered about it so would be interested to hear from anyone who knows exactly what it is.

From what you describe, pretty sure it is your power converter. Basically it converts ac from your shore power to DC. Even when connected to shore power, your lights run of DC. A 'smart' converter senses a weak battery and will output a higher voyage to charge your batteries. With your battery disconnected, your converter may be overloading your dC circuit. Try hooking your battery up and see if the noise continues. Is so, you may have a bad converter

Will connect the battery. Great advice. It's so rare for it to happen right now (twice, that I've noticed in 2 weeks. Not a big worry sitting in driveway but major headache at sundown on a chilly thanksgiving trip I guess.
Converter replacement hardware doesn't look that expensive but I'm sure labor would be quite intensive. Anyone had to do that?

Before you replace your converter, verify that it is the problem.

Here is a good link for testing a power converter
https://axleaddict.com/rvs/RV-Camper...nd-Replacement

My converter was made by progressive dynamics and when mine went out I was able to call their customer support for help in diagnosing the problem.

Before you can test the converter, you need to make sure your battery is good and will hold a charge. As a side note, to keep your battery connected and being charged by the converter will improve the life of the battery.

Question. If you are plugged into a 30 amp from the house, why would you disconnect the battery?

My water heater makes that sound when heating, whether on gas or electric. I looked at it and it appears to be coming from the circuit board. Like I said, it only makes the noise when the burner is on.
