Thank you for all the effort you put into your videos. We've been full time for 1 yr and 3 months and the dang fridge just went down. Dont wanna buy a new one if its something easy. From what I think you said in another video is I can unplug the thermistor and that will put it into full on mode and that will give me an answer? Dont have a thermometer or I would test it with the meter.

Okay, please elaborate where you say the refrigerator went down. Do you have power at the eyebrow board, does the light turn on when you open the door? Or has a whole thing gone dead in the water? By having the thermistor floating in the air, it will effectively communicate to the the burner to continue distilling the ammonia, which creates the cooling effect. See, the thermistor is not reporting back fin temperature but air temperature. The board has no idea of knowing this and will continually try to cool. The easiest way to troubleshoot these refrigerators is on electricity because there's fewer elements that could fail with regard to the lp side.

@@MountainTopHomestead316 Are your coils on the back side hot/warm everywhere you touch them? No cool spots? If you have cool spots then you are most likely looking at a blockage in the cooling unit. If they are warm, we can assume the cooling unit is fine and it could be either the instillation (chimney affect I alluded to in my drawing on this video: kzitem.info/news/bejne/qoqVm3x9nmaiYKA) or an ice damn that I discuss in this video: kzitem.info/news/bejne/qWN5zWFtknqqjHo. One more thing that comes to mind... Verify the ohms and amps on that heating element to make sure it is operating fully. Also verify the wattage per the mfg spec. I have seen where the incorrect wattage heating element was installed by others. I have manuals on my website here: myrvworks.com/manuals/

Thank goodness. Your channel is great. But I have a question. How can a bag thermistor make fridge hot? I thought if they failed they would get too cold. I definitely subscribed. Sharing you everywhere I can‼️

If the thermistor falls off from its perch and is still working, but reporting on the air temp vs the fin temp, it will send a value that it is too hot and therefor the frig will continue to run the boiler. If the thermistor ‘fails’, the question then becomes which way did it fail (reporting too high resistance or too low)? The thermistors only purpose in life it to change its resistance based on temperature. In the video here it was sending bad data to the control board. Hope this helps!

First, thanks so very much for your videos on so many rv trouble shooting and repairs. My RM2862 Dometic refrigerator is running at 41*f with the thermistor almost all of the way up on the fin. The interval setting is up to 4 from 3, which is where it’s always been for the last many years. I did an ohm test and got a little above 8,600. The chart from your resource indicates that at that value, the temp should be +/- 34-35*f. The value at 41*f should be 7,240 according to the chart. Am I correct to believe that the thermistor should be replaced? The freezer is still keeping things frozen, but I’d really like to have the refrigerator temp more towards the 35*f area. Thanks again for your easily understandable and very valuable videos.

Sounds about like mine. I put a temp gauge in mine and it will get to 40ish but takes about 3 days. Once I started opening the door during regular use I was hitting up to 55°. At night by morning it will back down to 40-45. I tried to run the thermistor up to the top to see what it gets down to. Mine is only about 2 years old and is not keeping up at all.

Our Dometic fridge runs too warm (50) and freezer solid cold. Found thermistor off clip and reattached to top of fin. Still same result. Starting to learn how to use multimeter and will check resistance numbers for this manufacturer. Your videos are spot on for information and detail. Thanks for taking the time. Any thoughts on these "adjustable" thermistors I see on the market? Will they damage anything?

Thanks for all your videos. I have a Norcold N841. I got the “no co” code and I checked everything you said in several videos. Heating element good, ventilation good, 115 volts good, 12 volts good. So I noticed 2 dark burned areas on my control board. I bought a new one and replaced it. I reset the fault code on my eye panel on frig. Everything worked great for 12 hrs. It through a “no co” again. I checked my thermistor and it shows 9.8 in ice water, which is bad. My question is, will a bad thermistor made the frig throw a “no co?” I am replacing it but just wondering? Thanks, Craig James.

Confused new Tech here! Testing a domestic thermistor in a little Image trailer: Does your volt meter have to be set on ohms or like auto Ohms setting? When I test a thermistor on a Dometic refrigerator my meter reads OL on Ohms. Have I diagnosed this right? Break in the circuit /bad part? Is this right? But when I hit a button on my meter it goes through a few other Ohms settings and I get a 9300 reading on my meter. Which is the right setting? I know they can read between 8500-9500 ohms give it take 10%. Thank you!

So I have the Dometic RM 2454 whether it's on electric gas or 12 volt it's just barely keeping up with cool around 45 or 50 I slid the thermistor up and down didn't make any difference other than I took it out of the clip and laid it in the middle of the rack and it went down to 38°. I checked the resistance on it within ice water and it was 8.0. Can the thermistor work one minute and not the next should I change it out anyway?

Hi Darren, I have a Dometic DM2662. This morning I noticed it wasn't very cold. Using your video about testing the control board and element, everything test good. The propane lit, and the element read 2.79 amps. So i wasn't sure what was happening. A few hours latter I opened the fridge door and the inside light did not go on. I thought it my be the bulb, but them I noticed the lights on the eyebrow board where off. I tried to turn it on and off but nothing. It's raining out right now so once it stops I'll check if I have voltage. I check your resources for a service manual for this model but could not find it. Is there another model that is the same so I can check the Ohms on the element and the thermistor. With no lights on the eyebrow board I'm guessing the eyebrow board was going bad and finally burnt out completely.

For a dometic rm2351 I’m only showing 2.5k at 80°. And 5.2k at 39°. So do these specs apply to the dometic? Now after sitting a few minutes it shows 7.9k at 37°. I am using a wireless grill thermometer in a glass of ice water sitting several minutes. I don’t think my low end temp is very accurate on my thermometer honestly. I did find the specs that says at 33-35 after 8-10 minutes I should read 8-10k. Not sure why I had a odd jump but I pulled around on the wires and it didn’t seem to change so I’m assuming it was just the thermistor adjusting to the new temps in the glass of water. I’m going to try to just readjust the thermistor and see how it goes before I go buying one.

I have a small, older dometic refrigerator and am trying to make sure I'm turning it off for certain. There's a couple off positions on the power source selector switch so I'm good with that, but the temp control switch is hard to turn and the off position never actually comes into view on the switch. I turn all the way left and it goes a hair past the 1 setting and all the way right past max setting and I can see the off but not fully whereas I vaguely see it when turned down to the 1. I would assume it would be off near the 1 setting but the indicator shows off closer to the max setting. Which way is the correct direction to be off or does it even matter since its in off on the power source selector anyway. Thanks for any input. I know, stupid question huh.

Hi Linda-jo, Procedure is the same but ohms values are different. Adding fans will help for sure. Watch some of my other refrigerator video's and I discuss more on performance issues. On my website you will find a service manual library. Find your model number and you should be able to find the thermister/ohm value chart in the manual. If you can't find it lemme know and I will help you - just send your frig model number... Here is the link to my library: myrvworks.com/manuals/ Dometic has reached out to us to create some refrigerator video's for them to share on their site, testing a thermistor is one the list! In a few weeks we will be uploading about 7 (or more) video's on our channel here that cover refrigerator diagnosis and best practices. Stay tuned for that... Cheers, Darren Koepp
