Norcold LI-op Error Code

We reset ours with a magnet - very high humidity for a long period of time caused ours to trip. It's been fine since.

I think you're right. After having the overheating cutout box replaced once, we had it trip again after the detailing guys pressure washed the rig. I found moisture inside the frig vent area. After drying that out, I used the magnet to reset the reed switch. It has worked just fine ever since.

If you open up the outside access door you will see a Red LED light on a black box. That is the Temp sensor control. Li-op is the same code as NO CO. Your Box is wired thru the main control board so will show Li-op. You state it is raining. See if the rear area of the refer and that box has water on it. THAT will trip the boxes. The only recourse you have is to do the Magnet trick. The other is NOT a good idea---bypassing the control box. As another stated, the Limit system is there for SAFETY. In normal operation, it will trip and shut the refer down when the flue area gets over 700 degrees. The normal temp is around 350 degrees. The correct safe procedure when this Li-op happens is to have the refer and system checked by a qualified Norcold technician to verify there is NOT a safety hazard and the system did its job. Doug

^^ This is the most informed response. Listen to him.

Yep. The magnet thing seems to be the official response for it. Worked for me a couple of months back after a frog-strangler rain one night.

I reset it about 90 minutes ago and the fridge seems happy for now. I’ll keep an eye on it.

Half the people in camp were outside this morning dealing with various issues from last night’s storm. The gods seemed to have a score to settle with some of us.

My coach is only a few months old and had this problem.
I took it in and had it checked out and they couldn't find a problem.

It only happens on hot days when the refrigerator side is exposed to direct sunshine. The coach has dark paint thus aggravating the problem.

I take the cover off and let it cool down and then reset with a magnet.

Shade from the awning prevents this
problem.

I should put a small fan in the compartment but it's not enough of a problem to motivate me.

It could be that the switch just failed "OR" you have an issue in your flue (burner tube area). Have you serviced (checked/ cleaned) the tube area?

That temp switch is there for a reason.;)

After a little more rainy night Googling, I did find THIS THREAD that discusses resetting the switch with a magnet. I'll give it a try in the morning when it's light out.

Fingers crossed.
