Freezer has not reach down to zero

I can't give any advice about heating tubes (because I don't know) but here are our cool down temps and times on a 821. Something to compare with?





Here are the cool down temps: (using elec not propane. Will do propane next defrost time)



Time............Fridge.................Freezer

750PM...........78.....................78

906Pm...........66.....................46

1010pm..........59.....................16

1108pm..........51......................7

1200 midnight...47......................-1

Why does it need to reach zero? We keep ours between 15 and 20F.

How cold the freezer is decides how hard your ice cream is

I have Norcold - Model # N821FLT. Refrigerator temp works fine 40 degree but freezer has not reach down to zero. I increased setting from 4 to 8 last night. I use Multimeter Clamp to test heating tube. It came out between 1.2 and 1.4 AMP. I would think the heating tube works fine? Made me wondering if it is time to replace heating tube? Any advise would be appreciated. Thanks Advance?

What temp is freezer at?

Electric heat element is a 300W rated at 2.5A - 2.7A with 120V AC

Fan in outside compartment.........working?

Does it work any better on LP?

I was never able to keep ice cream solid in an LP fridge.

As present time - Outside temp is 81 degree. Earlier afternoon the fan kicked on. But now fan is not running. Eastern time 2000. Refrigerator remain the same 40. Freezer 20 degree. (Amp - 1.4) I turned down setting to 5. Voltage - 112 AC.

I have thought about it. I will wait tomorrow if not improve then will switch LP.

You are not using the correct tools. The Heat Element for your model is a 300 watt 2.4/2.6 amp Heating element. Heat Elements either WORK or they do not heat. There is no partial heat from a Heat Element. Freezers in almost ALL RV refers are NOT controlled by the tstat. They will get below 10 degrees regardless of the tstat setting. The operational range of a RV refer freezer is 0 to 10 degrees. Most will get slightly below zero, but that is rare. The reason the freezer does NOT need regulation is the design of the cooling unit. The extreme cold for the refer happens at the top and then goes down to the lower section and then is regulated. Has any work been done on the refer? Doug

PS, 40 degrees is NOT good. It should be below 36 degrees. I suspect a partial blocked Cooling Unit.
