NORCOLD Refrigerator turns off by itself turns on with light switch

My NORCOLD refrigerator in my 2016 Columbus 340RK turns itself off after 24 hours everyday that it is turned on. It does not matter if it is running on electricity or propane. This problem has occurred on ever trip since I bought it new. It has been at the dealer for more days than I have actually used the coach. The dealer has changed two boards and it still has not fixed the problem.

The refrigerator now will only allow you to turn it back on when the light switch near the refrigerator is turned on. Please see attached video. You can also hear a fan speed change with the light on (fan has more power) and the fan has less power when the light is off. The refrigerator gave code AC RE twice out of the 6 day trip

It concerns me that the power from a light switch effects the power to the refrigerator. I spoke to NORCOLD last summer concerning this and they advised that it may be a power converter problem and not in the refrigerator at all.

On the last day of our trip while we were running the bedroom slide in, the refrigerator turned itself off and displayed the code given above.

I love the coach but we canít continue to enjoy our investment without the normal use of the refrigerator.

Has anyone ever encountered this problem???

Welcome to the forum its a great place to get your questions answered. I have not had this problem and think what I would do to find out if it is the frig or the coach. I would rig separate 12V and 110V power leads to the frig and allow it to run and see what happens. If it quits its the frig if not its the coach and you can trace the problem from there.

Thank you Sea Dog. The coach is going back to dealership today. I will suggest your idea. Fingers crossed....

How new is your battery? Reason for asking is when you pull the slide in the fridge went off. There could be low 12 volt supply voltage. This is common to both propane and 110 VAC operation. Control is 12 volts.

Problem areas

Bad Battery
Bad Grounding, corroded or loose connection
12 volt wiring to fridge has a ohmic connection, bad connection that when the current rises causes it to partially open and drop voltage

Your service depot should have a decent Digital Meter and should able to set limits on voltage. Track lowest voltage present. An old style meter with a analogue face would show it really fast seeing it drop.

Sound to me troubleshooting from a distance voltage drop causes the fridge to turn off our too low voltage.

First thing is the refrigerator needs to be on a filtered dedicated circuit from the power distribution panel. Nothing else should be on this circuit. The RV power supply to the refrigerator is wired improperly and this issue must be resolved prior to any other trouble shooting. Must have been wired incorrectly at the factory (wouldn't be the first time). The error code you reference means that the AC relay is stuck closed and the power board must be replaced. However, I would ensure the Refrigerator wiring be corrected first, turn on the refrigerator, and see if the fault code clears. Make sure all fault codes get erased from power board memory. Let us know what fixes your problem.

Thank you to all for the responses.

B and B the batteries (4 6 Volt batteries) are 2 years old. The volt meter on my leveling system read 12.4 volts at the time the slide was brought in. We were also still attached to the park 50 amp service.

RV Doctor, when I took it to the service center today, the manager advised that they will hook up the frig to their power and check to see if that is the problem. This afternoon, the manager called me back and said that they were able to duplicate the problem when my BATTERY SWITCH WAS OFF. He asked if I normally run the refrigerator with the battery switch off. I advised that the only time I turn the battery isolation switch off is to store it. When I go hookup to my truck for a trip, I power the coach up at the switch and turn on the frig so it can cool for the trip. I never dreamed that the refrigerator would even work with the battery switch off. When we took delivery we were instructed to turn the switch on anytime we power up any system. I did find out recently that my leveling system is constantly hot. Iím not sure why the coach has a battery disconnect if systems still work when itís in the off position. I drive a fire engine for a living and all systems are off when the battery isolated is off. So, not sure why an rv would be any different.

Also doc, they replaced the power board the last time it was in for this problem.

The refrigerator should not work if the master battery switch is in the disconnect position. Only when it is on. This prevents battery from going dead while the rv is not in use. There is still a wiring problem that needs to be corrected. Also, check for AC ripple at the DC power leads at the refrigerator. Disconnect the DC supply leads at power board and check for AC ripple at the leads with a good voltmeter with rv plugged into shore power. If AC ripple is present after ensuring the refrigerator power supply is wired to a filtered circuit on the DC distribution panel then the power converter is at fault and needs to be replaced. AC ripple can cause all sorts of problems on refrigerator control boards and definitely can cause the type of problems you are having. Google AC ripple for a full understanding and how to test for it. Norcold should be able to supply AC ripple limits. I can't remember the maximum AC ripple limits allowed.

The fire truck I drive operates the same as yours and you are correct that an RV operates the same way for the same reasons. That is why they call it a master disconnect.

I am in need of some advice.

I had a conversation with Columbus Warrenty and their shop manager on April 4 concerning this problem. Their shop manager advised, after explaining the problem, it sounded to him that it doesnít sound like the refrigerator is on its own circuit.

Today, I was informed by the dealership shop manager that they hooked up my refrigerator to their power and propane that the refrigerator worked fine. He said that they ran the refrigerator on tne fifth wheels power for 3 days and it worked fine. He spoke to Columbus and explained the problem and that Columbus will not authorize him to wire my refrigerator to its own circuit.

I have called and emailed Columbus and have not been able to speak to anyone.

Does anyone have any ideas what I should do next? I am worried now that the coach may not be safe from an electrical fire.
