Norcold double door fridge not getting cold enough

[powerscol]

Wow! This morning the fridge was down to 30 and the water in the cup was frozen. I've got a new thermistor coming today so I'll see what that does.

Look in your manual for where the temp probe should be sitting. Sounds like it is working great. Instead of a new probe have you changed/adjusted the settings?

I would also load it up (water jugs) and see how it does.

Thanks for the info. It does work great in the morning when it's cool outside. Then it starts warming up later in the day.

Yesterday when it warmed up to about 85 outside the fridge also warmed up to over 40, the freezer warmed up a lot too.

BTW I've got it set to 9.

Have you check the outside vent to make sure they are clean and that the upper baffle is still in place. Do you hear the outside cooling fans come on. If not there is a fuse near the control module and a second inside the control module that control the stock fans I am assuming it is vented to the outside as it is in the slide.

Just went out and checked and the outside fans are NOT running.

Possible fuse issue? I'm going to pull the manual out and track down where the power/fuse for the fans are located; unless someone can tell me.

First thing I would do is with the refrigerator on (gas or electric make no difference for this) jumper the thermal switch (which controls the fans) (item C in the schematic between my points AA and AB) located on the left side of the condenser(?). It is under the outside top vent cover on the left side of the black finned radiator (condenser - not sure that is the correct name). If the fans turn on, they are good, and your problem is (partially) the thermal switch. Common problem for them to come on at to high of a temperature.

For the Norcold 2118, from our owners manual, there are only 2 fuses (possibly 3 with optional "winter" heater - which ours has). The two fuses are located on the control board access from the outside, lower vent cover. One is a glass fuse for the 120v AC side. the other is an ATC/ATO (automotive) blade type fuse for the 12V DC. Be careful. There is live 120v AC on that board when your trailer is plugged in or running on generator or inverter.

Ignore my chicken scratchings. I added to additional external fans.

Try to add schematic in separate post (to long for first)


I cannot seem to add the schematic. Please check your owner's manual or google "Norcold 2118 schematic".

Nice info Chris. That’s where I’ll head tomorrow. I’m pretty sure it’s a fuse issue because all 3 fans stopped working. The non working fans explains all the symptoms I described.

The factory fans are junk. Both of my upper fans failed. I replaced them with quality units, waterproof with a 50,000 hour rating. About $20.00 each.

The fuse blowing is the first symptom of failng fans. That is what mine did. It will blow somtimes when one fan fails. When they both fail, it will blow all the time.

Awesome info Chris. I'll take the cover off and check.
