Norcold 1200LRIM Cooling Unit Failure
Our Norcold refridgerator stopped cooling. We confirmed both AC/DC power and circuit board ok. LP comes on when AC off. Neither mode cools. Local RV repairman said heating side of unit was working...

1. The REAR fans should be operating
2. You HOT wire BOTH 120 elements for 24 hours to verify cooling unit
3. If a Blockage, it is INTERNAL and the blockage is as hard as a weld and is also "welded" to the inside upper cooling unit tube. Rebuilders have to cut out th section of tubing on the CU and replace that section when a blockage happens as you cannot remove it.
4. If you have a LACK of ventilation (blocked, not just fans not running) that will "cook" a cooling unit and once that happens the CU is bad and must be replaced.
5. Usually, the recall box will trip from a bad cooling unit, but not always. Doug
