RV Fridge NOT COOLING? - Quick and Easy Fix - Thermistor Hack - Dometic Fridge 

Never realized the thermostat was adjustable within the plastic slide piece. Great info and vid, thank you!

I came to RU-vid to research why my RV refrigerator wasn't cooling and I'm so glad this is the very first video I watched. After the video ended, I went to check my temperature slide and the cable was completely off and dangling. I'm glad I didn't have to waste hours on videos that would have had me jumping through a bunch of unnecessary hoops! Thank you so much for this video. Now I have to wait 24 hours and see if me reconnecting the cable worked. Fingers crossed! 😆

Just learned something new. And it couldn’t have been more simple. Thank you and keep producing videos. I have now subscribed.

Solved my problem instantly. I was used to the knob style temp control. Thanks so much!

Thanks for this amazing video...short, to the point and most importantly effective!! You rock!

Great video! Quick, to the point, and super helpful! Thank you so much!!

Took your information and used it on my 1998 Dometic RM 2652. Did as you had. Fridge is now roughly 36 degrees

Awesome hack!

Very helpful quick fix.

Perfect fix! Thanks bro!

OMG. I had no idea. Thank you so much. I've been watching other RU-vid's and trouble shooting all day long since yesterday. I had no idea this thing even existed. I saw the hot and cold on the side of the fridge and couldn't figure out what I was supposed to play with. I even read the trailer manual with the fridge pamphlet in it. I was thinking about calling a repairman and how much it was going to cost. I just pushed it up and have not even checked but pretty sure that's it because I heard a hissing sound.

Dude thank you so much for this!!

I honestly didn't even know that temp control existed. (I have no cooler/warmer decals) I was worried I was gonna have to replace the whole thing. Had the exact same problem, this was the exact fix.

Thank for making this! Helped alot

Thank you! Very helpful!

Well I'll be jiggered... That's what that plastic wiggly shaped funky piece is for haha... I had no idea, and to find this video just when my fridge decided to become his brother the freezer!! A fixing we will go hi ho hi ho!! Thank you! ya gotta love You Tube the University of "well I'll give it a try" !

You rock! Mine had completely fallen out of the slider and was hanging down. What a terrible design.

You rock, Thanks so much.

Honestly Dometic suks, I have had nothing but problems but thank you for the white tape idea, you are the best! ❤

Thanks. Having the same exact issue, hopefully this helps.

Thx brother u just saved me a big headache

Thank you! I have a Dometic RM2354 with the thermostat on the front of the fridge. This is in my four wheel camper. This fridge has never gotten colder than about 30 degrees colder than the outside temperature. So if its 90 outside its high 50's low 60's. The thermostat you showed in your fridge has the sticker that showed colder or warmer. My fridge doesnt have that. The thermistor in mine was all the way to the bottom almost hanging out. I tried to move it up and there was not enough wire. I looked at the back. When the thermistor was originally installed. The tech routed the wire up and over a coil. It had even melted the outside cover a little. I routed the thermistor and wire a more direct route and put it all back together. Now the thermistor it all the way to the top. I have my fingers crossed.

What that Thermistor is recording is the internal temperature at a given level within your refer and regulating the output accordingly. Heat rises and cold is denser therefore falls. Putting an internal fan within your refrigerator would cause the thermal layering to be almost non-existent and the thermistor to call for cold based upon the unlayered temperature of the internal box.

Nice job god bless

Worth a shot at least. Mine just stopped cooling one day, would still run, but no cooling. Sad part is that all wires look fine, no ammonia leaking, guess the old girl just had enough.

Thank you!! We are going to try this. We seem to only have trouble on extremely hot days. It was very frustrating!! Do you find it works better when you are not on gas and plugged in or is it the same problem?

Ah nice to know. I knew you could slide them but didn’t know anything about them shifting inside. Update I checked mine and yes mine was at the bottom the same as yours. Problem is mine has no slack to get it more than half way up. When I go outside to look there is a tubular thing with a shield in the way were the wires would be coming out. I can’t even see the wires so I’m screwed. My fridge is hitting temps of 50-55 when I start opening it.

We had a prolonged cold snap in December, apparently it affected the hydrologic leveling system and the RV wasn't level, took us a while to figure out that this was the reason our fridge stopped working, not the freezer, just the fridge

Hi, i am a little confused. Isnt auto + light to run on battery and the button popped out + no light for gas?

I cant figure out why my check light keeps turning on some days it won't be on then it comes on I'm using electricity... am I suppose to push the button to auto

So my fridge has the same thing but my plastic peice too hold the temp sensor is missing can I just tape the sensor toward the top of fridge above the colder sticker on the side of the fridge or does it need too be inside the plastic peice on the fin ?

We have a Dometic full size fridge in our RV it shows an Err 13 on the display. Does anyone know what that error code is?

Why does the thermister need to be at the top of the clip? Mine does not have a long enough cord.

I used and alligator clip on the bottom right when I got it and this damn thing only goes down to 50f in the fridge if it’s 70f degrees outside, freezer will go between 4 and 15

I have a Dometic 8501. The thermistor is held by a similar clip, but the clip is secured to the fridge back wall by a torx screw. Even when I remove the screw the thermistor wire won't let me slide the clip up. I'm going to try to trace the wire from the back of the fridge to see if I can loosen it, but there's not much working space on the backside. Any other ideas?

Just got my camper today and it has no temp control or anything. Freezer seems cold but fridge is doing nothing.

What if the white plastic piece is missing?

My temp thing is on the left and everyone else’s is on the right but I don’t think it matters.

Is there an improvement when gas isn't running?

Mine don't got a clip, just a wire that hangs in the fridge😭

Both my freezer and fridge isn’t working

I've had my thermostat piece touching the top of the fridge for 8 hours today and im still having this issue. My freezer is freezing but the fridge is like 60 degrees.

I tried this and put fridge is still warm

dab of hot glue...

This is the absolute worse design I've ever seen. Can't get mine anywhere close to the top. I hate everything Dometic

Yep. Dumbest thermostat design EVER. I REMOVED the wire from the plastic and used a clip similar to what you did.
