Norcold N611RT not cooling in either AC and LP modes.

Hi,

Model Norcold N611RT

I'm sure the answer to this problem exists somewhere on this site, but I figure it might be quicker to ask.

Before leaving the trailer on our last trip (two weeks ago), we left the refrigerator on setting #1 in AC mode. This had previously kept the fridge cool between past visits.

When we returned to the trailer last Friday, the fridge was warm. The green LED was on, no other LED was lit. We had confirmed that a power failure occurred in the park. (This may or may not have something to do with our issue.)

I turned the switch to the off position and turned it back to auto. The green LED came back on, as well as a flashing orange LED. This made sense since the LP gas line was shut off.

If I remember correctly, I again turned the unit off and unplugged the fridge at the back panel and plugged it back in. I then returned inside and turned the switch to auto. I believe the orange LP light stopped flashing.

We waited for a long time, and nothing cooled in AC mode. So we then turned the unit off and opened the LP gas line. I returned inside and turned the switch to GAS. We waited again for a long time and nothing cooled in GAS mode.

I do know that in GAS mode, I can hear things happening. At the back panel, the unit starts (flame and all) and I believe I can hear venting. The last time we used GAS, the fridge seemed to cool quite quickly, but yet no coolness inside the fridge and freezer areas.

It was quite hot out this weekend, so maybe that's a factor?

The power panel fuse seems OK, but I didn't check the control board fuse. I'm thinking the control board fuse is fine since the unit appears to start in GAS mode.

So if I troubleshooted things appropriately, the unit doesn't appear to cool in any mode (AC or LP). Power to the control board and fridge appears to function well.

Any help is much appreciated.

Thanks, Rick.
  • I'm having the same problem. My board fuses are fine. The heating element gets hot in AC mode. I hear the relay turn on. My flame lights in GAS mode. But I get no cooling in the freezer or fridge. When I touch the black tubes of the the cooling unit, only the very lowest level tube is hot. I'm thinking its the cooling unit that took a dump. This thing was working very well for a few months since I got my 5th wheel. Then overnight it went out. My refer is a Norcold n811. I'm curious to see what you figure out. I want to make sure its the cooling unit before I replace it becuase its basically the most expensive part by far. Thanks everyone for your replies to this thread so far.

    The best way to determine CU is to hot wire the 120 element for 24 hours. This bypasses the controls. IF the Refer does not get below 38 degrees, the CU is bad. DO NOT run more than 24 hours in hot wire. Doug
