Clicking sound under bed when hooked to shore power...

I have looked at many posts dealing with clicking noise while hooked to shore power, but can't find one related to my problem. I am getting a clicking sound under the bed while hooked to shore power. It is NOT coming from the transfer switch. It sounds like it is coming from inside the breaker panel. I can "trip" the GFI breaker and reset it and the clicking goes away. Of course after a few minutes the clicking sound returns. Is my GFI breaker faulty and is this causing the clicking sound. I have a 2006 Revolution LE. Everything works great when running the generator. Thanks

Transfer switch clicks, can be loud.

Completely normal-each click is for each breaker in your panel. If you watch the power display panel it'll illuminate a light for each circuit as they turn on.

On my 2005 Revolution LE - I would get a clicking sound when I would plug into shore power or run my generator as well. The "click" would be pretty fast-paced (guessing 2 clicks per second) for a while and then go away eventually after running the generator for a while, driving, or being plugged into shore power for a length of time. Everything functioned normally, no power issues, nothing else out of the ordinary. Like you, the only place I could track it down too was the fuse panel mounted near bottom of the bed.
Totally unrelated to the clicking, I replaced the house batteries and coach batteries, cleaned the contact points and tightened all the grounds I could find. Now I no longer hear the clicking. My only thoughts are that the batteries were low, or there was a ground issue with a relay perhaps at the same location behind the fuse box.

Does your clicking eventually go away, or is it constant?

Have you remove the panel under bed to verify where itís coming from? Should not be anything under bed that clicks besides transfer switch.

Once the clicking starts, which is anywhere between 30 mins to a few hours after plugging into my 30amp service I am using for it. It does not go away once it begins. The green display lights in front of unit on the EMS, display fully until clicking starts. Then they start running up and down constantly. I do not hear the sound coming from the transfer switch. I am within a few inches of the sound and it seems to definitely be coming from inside the fuse panel box. Thanks

Weird, this sounds very similar to what I had previously. My EMS display unit would show odd numbers, click from the same location you are describing, but everything would work properly ( w/genset running) and then after some time (varied but more than 30 minutes) the clicking would stop and the EMS would display the proper amp usage. I did find that when I flipped one of the breakers on the panel, the clicking did stop. So I absolutely know it wasn't the transfer switch, but definitively tied to something in/around the panel.

My clicking went away after replacing the batteries (for issues unrelated to the clicking) combined with cleaning and tightening the grounds and battery cables. My only thoughts were that the clicking was related to batteries not having enough juice to close/keep closed a relay until the genset had run long enough to bring the batteries up enough. This is admittedly based on 2 potentially unrelated events happening around the same time - and having other problems higher up on my list of things to do so I didn't bother digging too deep.

Good luck!

You can remove front face cover and look.

I am going to remove the breaker panel front tomorrow and try and get a better location of the clicking source. Thanks for all the suggestions so far.

Better track it down. Might be a camera installed by a previous owner. Lol.

Changed out the GFI breaker. It's been 5 hours and so far NO clicking sound.

My clicking sound is back - so did you just change out the breaker in the panel and everything went away?

I had it clicking for a solid 16-18 hours, before it stopped this time. I did take some pics just to highlight exactly what was clicking to see if there is any wisdom before I just start throwing new breakers at the problem...

This is the panel with the front cover removed - the clicking is coming from the control board on the right.

This is the board out of the panel, the clicking is coming from one of the relays on the right. Couldn't figure out which one even with my fingers on the relays (felt like maybe they were all clicking, or just felt that way because of proximity)

This is what the control panel up front looked like, oddly, I was plugged into a 20 amp outlet, the generator was not running. The numbers/letters on the board change or sometimes don't make any discernable pattern while the clicking is happening. When the clicking stops, it goes back to showing the incoming power source correctly (20/30/50 amp, gen set) and the load currently in use.

Any thoughts? Thanks in advance.

That is a load shedding control board.

While on 30 amps the board monitors the current and when it determines you are right at or over the limit it begins "shedding" circuits. Such as water heaters, air conditioners, washer/dryers etc.

It can begin shedding at less than 30 amps if it sees a constant very close to 30 amp load. It can take you down to around 24 amps by disconnecting circuits.

So the thing is likely doing its job well.

Now for possible solutions. You must find out what you are running on AC. IF you have your water heater on electric mode, switch it to propane as well as your refer if it has that capability.

Since you have a sophisticated system you may be able to turn your charger down. That is, it is likely running at 80-100% which is not needed once you are charged up.

I have a round know on my control panel that allows me to program the charger to many settings.

If you are trying to run a floor heater while on 30 amps you are really tempting the load gods. They can eat up half of the available current allowed by the system.

Turning off whatever GFCI you are using is just doing a manual "load shed".

I hope this helps and I will be back with some more infomation,

Here is the factory explanation.




This is a service type video but the information is excellent.
