Having a vexing issue right now. Occasionally when the furnace kicks in, the fridge will switch between AC and Gas, not just over, but the lights on the fridge blinking back and forth. I can hear a clicking noise that I have an issue locating. If near the back of fridge it sounds like it is coming from there, if you are near the Intellitec ECC it sounds like it is there. I replaced the Intellitec module, but still happens, so I guess I have a good spare! I am about ready to replace the board on the fridge, but not sure I need another spare.

Seems to me, it is a voltage sensing issue, which makes me wonder about the power converter. If a soliid 12v is not available? I have a multi meter, know how to use it, but what is your idea?

AC seems fine, I have a line monitor and it shows no variation during these episodes.

Check the ground wires at the refrigerator. Sometimes to a bolt on the refrigerator. Also set your meter to ac voltage and check the dc input to the refrigerator. If it reads more than 3 volts ac on the dc circuit you have a converter problem.

Thanks Steve, I checked the voltage and all looks fine, retightened ground connection, and I think this might be the issue, we disconnected our ice maker awhile back, but the wires were still connected to AC. Disconnected that and has had no issue since., Still crossing my fingers! But looks like my converter is good.

Steve Thought I would update. I changed out the Intellitec module, no change, checked voltages, grounds, seated connectors. No change, it would be OK, then not OK. THEN everything was fine, I flipped up the flourescent kitchen light and fridge started getting goofy again, the clicking could be heard. Off the light, everything fine.

Solution, replaced ballast and for good measure the bulbs as well. All is normal. Now have a spare Intellitec module.

For anyone reading this. Having issues, funny stuff, consider the flouresent lights in the coach. Make it part of the diagnostic. Be sure they are all off, then turn them on one at a time. You may find it easier to replace entire fisture, the ballasts are typically riveted in, so you need to drill them out. The ballast is a little more than half the cost of a whole new light.

Consider replacing with LED's, there is a LED replacement for the tubes. Some can be aimed. LED replacements are a 'bit' more than a new bulb, but the service time is way longer.
