My 2017 Norcold Fridge Model N305R is not cooling the bottom of the fridge. The freezer is below zero but the bottom of fridge is not getting cold. Same on Electric or LP gas. I have a thermostor t...

1. The Thermister is NOT a Thermister. It is a silver capillary tube that runs from the 120 Tstat to the fins on the evaporator.
2. Your Gas tstat selector IS the tstat for the Gas side. You should have HI -MED-- LO settings on the gas knob. Unlike older BYPASS gas tstats, this system does NOT alter the flame height when temp is reached. HI is the coldest setting.
3. Your model SHOULD have a 12 volt cooling fan on the backside between the outer wall and the back of the cooling unit. You may not see it, you may have to remove the upper outside vent/door to see it. IT MUST BE RUNNING FOR COOLING TO HAPPEN. Some models do not have this fan(roof top venting), but for your type of install they are required, especially if NO roof top vent and the cooling air has to come in the bottom vent and then come out the top side vent.
4. WHILE YOUR MODEL IS not 3 WAY (dc BEING THE 3RD heat supply) you should have a 12 volt and neg wire connected to supply power to the cooling fan.
5. Your Tstat sensor tube connects to the 120 Thermostat and then goes to the evap fins. You have 2 separate tstats on your refer. A GAS tstat and a 120 Tstat.
6. The BEST way to test is to connect the 120 element direct to an 120 extension cord for 24 hours. Level the RV and this bypasses all controls. If after 24 hours the refer is NOT below 38 degrees and the freezer is NOT below 10 degrees, your cooling unit is BAD.
32 to 38 is the refer temps and 0 to 10 is the freezer temps. Use a cup of water after 24 hours to measure the refer temp.
DO NOT USE A IR THERMOMETER. They do NOT work for refer temps. Doug
