Currently at Normandy Farms in Massachusetts the temps are in the 90s. My Alpine 3535 has dual Dometic A/Cs with a two zone Dometic control. The front A/C (zone 2) works fine, but there only seems to be "JET DRIVE" for a fan speed. Even though the controller for Zone 2, allows fan speeds as expected (Hi /Med /Low/ Auto), there is no change in blower speed or sound level. It sounds like afterburners on the flight line! Zone 1 is working fine at the fan speed requested.

Even though the two units are doing a great job, the racket in the bedroom is an issue. Am I missing something?

Thanks,
