Domestic RM2852 piezoelectric fires over and over again.

I thought this was happening ever since you got that fridge. If you think it might be water doing the cross-signalling, maybe use a hair dryer on all the components and wiring at the back of the fridge.

The drain tube into (or not) the tray right by the spark and sense electrodes and their wires could be a suspect.

Good news if it clears up!

No it doesn't even light when switching from electric to gas. When I just switched it to gas it light and that was it. No continued clicking. So it seems like it's getting more rare. At first it was constant, gas or electric and it seems like it's slowly returning to normal. Could something have gotten wet? I ask because I cleaned the ice off the refrigerator fins the day before it started. I have the drain hose hooked up and didn't notice any water other than out the drain but I didn't check for maybe a tiny bit of dripping or something. That's the only thing I can think of. I switched it back to electric and this time got no sparking at all. Maybe something is drying out very slowly. It seems like it's almost or is back to normal. The only thing I can think of was cleaning it since it happened or at least I notices it the following day.

To be clear, it does not even flicker when first turning it on gas?

Mine has the two yellow lights, gas and check both on at first, then it catches (you hear it light and stay on gas) and check light goes out. When the fridge is turned off and then restarted on gas, it catches real fast so the check lamp just flicks on and off real fast.

Trying to figure if check lamp has anything to do with the flame sensor that does not seem to getting the word out that the flame is on.

On mine is the fat red wire from ignitor to burner and also a thin black wire to the burner, that has a connector along it. If that thin black wire is not connected, the flame sensor is disconnected, so I suppose it would keep sparking? (does not explain sparking on AC mode though)

Pulling the fat red wire off the ignitor board is not the same as pulling the plug out of the power supply board for that test.

No check lamp is always off.

Trying to follow the schematic to see where this could happen. What does your "check" lamp do while the fridge is in Gas Mode? When sparking on AC, is the "check" lamp on?

Will do when I get a chance maybe when my 17 month old is napping I can give it a try. If not then my wife will be off on Monday. Thanks by the way for the help.

So pull the ignitor plug from the board and turn the fridge on AC mode and report sparking or not---The World is holding its breath, wants to know! :)

Definitely doesn't spark with it off.

Be interesting if in AC mode the sparker stays off with the ignitor plug out of the board.

If it still sparks with the plug out of the board, then the mystery 12v supply to the sparker is external to the board, but still via the fridge control board (or it would spark even with the fridge turned off)

I messed with them a little yesterday and that seemed to help some so far. When I flip it to electric from gas it sparks a few times but isn't doing for hours at a time like before. I also noticed that it now eventually shuts off on gas mode too when it wasn't before its just that it takes a long time, say 30 minutes, an hour. I don't time it. So I think you might be right might be on to something. Not what I thought I'd be doing with a brand new fridge, I was looking forward to a few years with no issues... That's rv junk for you I suppose.

And yes in May it'll still be in warranty.
