1. NEW Norcold cooling units have the recall kit already installed. Have been for over 3 years. Never heard the term Cooling Tower.
2. LP pressure is CRITICAL for correct cooling on LP. Your dealer should have verified the LP pressure. If he did NOT, he has an incompetent Service dept.
3. Clean burner AND orifice is also critical.
4. "Moving the burner" is nonsense. Norcold Burners can ONLY be mounted and installed 1 way, with no variance.
5. The Burner has a BAFFLE that comes with a NEW Norcold Cooling unit. If they used an aftermarket CU, then they may not have transferred that baffle from the old CU. If they did NOT, then it will not cool on LP. The baffle is required for LP burner flame disbursement evenly on the burner flue.
6. If it works on 120 and does NOT on LP, then the baffle is what I would be looking at first.
7. The reason I think they used a NON Norcold Cooling unit is because of the statement about the recall that had to be installed. As I stated, IF you do not have the recall already installed and you are replacing the Cooling Unit with a Norcold Cooling Unit, that recall comes with the new Cooling unit. Doug
