Since BOTH units have the same noise, maybe the installer did not wire nut the Black and White 120 wires securely and they are arcing when the system has a higher amp draw. Doug
Doug I have checked all your recommend. THanks for that, but still no luck.

The control panel/s stay with the unit. All you replace is the upper unit. The New units are compatible with the original control board. Doug
