Fridge quit getting cold

[nunya]

Goodmornin! Got a problem with the fridge, it no longer gets cold in fridge or freezer? Control panel lights up, seems to also work on gas but no cold? I saw a thread about the thermistor problems, where is that located? I have a Dometic NDR1062 model in our 07 3400RL. I do have 120 power and all fuses appear to be ok, no loose wires? Got to -11 here in Moab 2 nights ago and thats when I think it quit? ANY help would be appreciated, 2 hours from a dealer and would rather fix myself if possible. Been fulltimin in it for 3 1/2 yrs. so it has worked hard. Thanks in advance for any input. Happy New Year!

It should be on the right side (looking at it) on the last fin.It slides up and down. It connects to a terminal on the control panel outside.. It sounds like itwent bad. It is not expensive and C.W carries them

richfaa, thanks for the quick response! I thought that is what that little slide thing was! I saw a post about unhooking it too see if fridge gets cold? Any help is great help, thanks again.

Seems like I read some where that the absorption refrigerators will not do well when the ambient temps get real cold.

Ron,
Look for additional threads on this subject. Someone had one freeze up and all the tech did was bounce it around. Your fix is on this site someplace.

I called Dometic and the gal told me that possibly the coolant gelled? Told me to heat the area behind fridge, so I have a 1500 W heater hooked up and a little tent built around the bottom vent and am blowing hot air in there and have the top vents 90% covered, it is getting warm and all is SAFE! Funny thing is there is a guy in a motorhome with the same problem, his RV tech told him to do the same thing! I will let this heat over night and give it a try again.............heres hopin! I will order thermistor in the AM also. Thanks again.

A few rigs her place a 60 watt bulb in the refer compartment and just leave it on during the winter as needed. Seems to work for them.

Thanks again! I usually tape off some of vents on both top n bottom covers to keep heat in, as I said usually! It got colder here in Moab than I expected and I was not payin attention to the weather reports...DDDDDDDDDDDDUUUUUUUUUUUUUUUUUUU! I will try turnin on the fridge later AM. guess we will see! NO yellow dust! This rig has been thru 3 winter-winters and has done great, I just didn`t this time!

fyi, no worky! Been back on for 3 hours and nothin, bummer! still have heater tryin to warm it but i think i got bigger problems? The one fuse on the curcuit board is a funny one AGX3 125v 3a, could not find one, gotta order, Radio Shack did not have one! Others are 1a,5a auto fuses found with no problem. Just passin in on!

Had the same problem in Kansas when it got down to 2. Called our dealer and he said sometimes the Dometic "gets confused" when there is a sudden or somewhat sudden drop in temperature. Something about the thermistor wire that goes through the back of the fridge is subject to outside temperatures and the sudden drop makes the fridge think it is too cold so it quits cooling. He suggested three things and this worked for us. The bulb had to be in there for a few days before it fully recovered. I'm now in Texas and it's working great.

1. 60w bulb behind the outside door, inside that cabinet.
2. move the thermistor all the way to the top so it will sense warmer air and try to cool more.
3. move the thermostat on the door to the coldest setting.

As I said, it worked. The temp setting is now back at 3 and the bulb removed. I left the thermistor in the highest position.

3 hours likely is not enough.

We just had the same problem and it was the heat tube. Dometic covered the part but not the labor. We had a mobile service come out and fix it for $169. If I knew how to trouble shoot the electrical end it would have been an easy fix.

Fridge has been back on and runnin great for 3 days! I did tape off the vents,bottom 2 rows on each cover and all toasty in compartment as well. Thanks again for all the info!

Good news! Being without a refer is not good.
