JRTH brings up a good point, we are only paid .5 hr to diagnose the problem, fill out a work sheet and submit pictures. There are times that the refer needs to run for a few hours. If the dealership doesn’t have the room to keep a unit “in the Bay” then I can see why customers think dealership techs don’t know diddly....and then there are those that don’t!!

So I sent away for a new thermister and main power board. I’m thinking if that doesn’t fix it, it has to be the cooling unit itself. If so, I guess it’s dealer time.

i read your first thread and it was confusing....one paragraph for multi issues is rough for us old people.


as for you a/c i assume it is fixed. just keep it always on auto.


as for the refrig I'd be talking to norcold support...i assume it is norcold.


good luck

The a/c seems to be working fine now (from first post) guess outside temp was to low at the time causing it to freeze up.
Checked ohms on fridge thermister at around 80 degrees it’s showing .865 supposed to be 8.1 range so I think it’s bad waiting for new one

Unbelievable!!! On this site someone showed an article from Norcold stating it is critical that the thermister be placed on the second fin from the right, 1/4 to 1/2 down from the top, just got an Email from Norcold saying it’s the third fin and it doesn’t matter where it’s placed. WHO THE HECK IS CORRECT??!!!

Does your issue change at all when towing trailer? Mine would seem to improve after a days driving and after sitting for a couple of days we would lose the temp again and it would rise to 45-50 degrees. Very frustrating. The dealer suggested removing the unit and tilting 45 degrees both directions and reinstall. I chose to replace with the Amish unit and what a difference. Good luck...

I have the same 2118 fridge. The Norcold Manual says second fin from the right, 1/4 to 1/2 down from the top. That is where mine is. with the fridge set on #6 freezer fluctuates between 2 and 9 degrees and the fridge air temp on the lowest shelf is 32-37 degrees air temp. The upper shelf is 28-34 degrees air temp. outside temp was 40-90 degrees. I took temps over a four day period running on propane. Air temps do not tell the whole story. I also tested water temp. Probe in glass of water. temp was 35-37 degrees on the lowest shelf. 50 degree air temp would mean a higher water temp. Not good! Keep in mind loading the fridge with warm liquids and solids will cause a increased cooling time. I pre- chill my initial load and add liquid items as they are used. IE one soda for one soda.

Per the different tech at Norcold, I moved the thermister to the middle of the 3rd fin, fridge started freezing food at 20, and freezer is at zero. So I changed the setting from 9 to 5, this is just crazy, but of course I’m in 60 degrees ambient weather. Still going to change the thermister and see what happens especially when I get back to hotter weather

Update..... now i’m down to a setting of 3.

That was me. Not an article, but an email sent to us at the dealership I work at. There may have been an update from the original dated email, but I (we) haven’t received anything.

Got the new thermister, and put a meter on it.It was reading 10 plus ohms, at least it’s reading ohms , that’s more I can say for the old one. I put it in and will see if it’s all running better in the morning. I have a circuit board too if needed.

Woke this morning to the fridge being 30 and it was set on 4. So I see it to 3. Will have to wait and see if it stays that way. But I’m thinking the new thermister did the trick

I went by what the letter from Norcold said. Second fin from the right, 1/4 - 1/2” down from the top. Not sure why the other Norcold person said it doesn’t matter wherein the “third” fin. It’s been almost 24 hours and it’s 30 plus degrees and it’s set on 2

As long as it’s working good, that’s what matters.

Amen to that. I’m just a little concerned that now I have it on “1” to keep it around 37, you’d think it would be at 37 around a setting of 3 or 4

May want to slide the thermistor a little to adjust? Just a thought.

That is a thought, but the last Norcold tech said, sliding the thermister to a different position makes no difference on a Norcold, only on a Domitech (spelling). But hey, i’ll Try it and see

Not sure what to try next, fridge is at 30 degrees hen set at 1 the lowest setting. The last tech guy from Norcold says the thermister should be in the middle of the third fin from the right. The paper some provided says second fin 1/4” from top. I’m going to try it in the middleman see if it makes a difference. The original one when received the unit was 1/4 from top. All so confusing when you get different instructions from the same company.

The common physics of the situation is that if you slide the thermistor up, the refrigerator gets colder because you're putting the sensor into a warmer region of the compartment; and if you slide it down, the refrigerator gets warmer because you're moving a sensor into a colder portion of the compartment. So try sliding it downward -- in your case probably quite a bit, since you can make up any overshoot with the manual temperature knob.

During a cooling cycle mine would show similar temps when set on the lower settings 1-3. The air temp will show different readings depending on the following factors. thermometer placement, cooling cycle on or off or just completed. Thermometer placement in relation to the fan. take a glass or bottle of water and take a liquid temperature from the lower middle area of the refrigerator. check it every 8 hours after adjusting the refrigerator temp level.
