Refrigerator/freezer issues

[prstlk]

We have a 2007 Holiday Rambler with a Norcold 4 door fridge, model #1200 LRIMSS.

We had the cooling unit replaced in February of 2015 with a new one (not re-built one).

We have always had to defrost the freezer compartment where the ice maker is located about every 4 to 6 weeks. The other side can usually go about 10 weeks.

About a week ago the ice maker slowed down on making ice. Used to fill the bin in 1 day. Now we might get 3 harvests of ice in a day.
But, everything on this side is rock solid frozen. We have checked the water like and there doesn't seem to be any kind of blockage in it and water is flowing to it just fine.

The other side is not freezing as well as a pack of hot dogs put in it over a week ago I can still squeeze and they give. They should be solidly frozen by now.

Now, the fridge doesn't seem to be cooling. I usually keep it set on the 5 setting and it seemed to always be just fine. Then I noticed things didn't seem to be as cold and it got up to 54 and we lost pretty much everything.

Then I put the setting on 6 and it didn't really change.

We have turned it up to 9 - the highest setting. Still does not cool down below about 47.

All of the above has been while it was on the AC setting.

We have now turned it to LP and it is now down to about 43. This is after running the LP for about 3 hours.

Any suggestions or ideas what might be happening.

Thanks in advance!

I have checked those and will work on them tomorrow.

We have checked the fuses in the front of the coach and the recalled switch to see if it is operating correctly and it is. Will check for the fuses in the board as well.

The weird thing is that we are not getting any fault codes or sounds from the control panel.

The other weird thing is that we are still getting frozen ice through the ice maker, yet not as much as we used to get in a day. We might get 3 or 4 harvests a day instead of being able to fill the bucket full in a day.

1. Was the Cooling unit a NORCOLD cooling unit?
2. Disconnect the Thermister to put the refer in BOM mode
3. Are you positive BOTH 120 elements are running(both are good).
4. LP pressure is critical
5. Clear ventilation up the backside is critical
6. CORRECTLY sealing the Cooling unit to the cabinet AND using the correct amount of Thermo paste is critical. Doug

Norcold has a good service bulletin that you can download, maybe from Bryant. You can check several things using it. There are a couple fuses on the power board on back of refer - could be one of them, could be the power board itself. Service bulletin is very useful.

We have now replaced the Thermistor and we still do not have a cold fridge or freezer that freezes.

We have tried it on both AC and LP and the results are the same.

We are nowhere near a service or repair place. There is a small RV service and supply company here but I really don't think they know what's going on.

Does anyone have any other suggestions?

Coils 45 sides 48, fans are running. Outside temp is 55, plug in hose
Thanks to all

Need to know what the temp is on the back wall of both sides of the freezer... needs to be less than 10 degrees for the refer section to get below 40, but where are you measuring the refer temps? On the doors it can be 8+ degrees warmer than the top near the fins. Since you open the icemaker side more often than the other... frosting up is going to happen sooner. A lot of frost around the icemaker will actually insulate it but I doubt you are getting below 10 degrees.

I'd start by making sure your fans on the back running when it's warm out. While back there make sure there is a plug in the drain hose in the container near the flue.
Dang I miss my 1200.:B :B :B

first thing is door gasket ,put a bungee cord with just a little tension on it across the frig door check before and after temps. if its leaking you,ll see a big diff in temp.
