Re: [DML] A/C cycling switch

["B Benson" <delornut@xxxx>]

The primary purpose of cycling the system is to prevent the evaporator core
from getting too cold and icing up to the point you get no air flow through
it. It won't ruin your system even if it cycles continuously as long as the
refrigerant level is with-in specs but depending on the atmospheric
conditions, you may discover the air flow coming into the cabin begins to
lessen as the evaporator ices up. If your system seems to be functioning
fine I wouldn't worry about cycling times, 5 seconds, 7 seconds, 10 or
whatever, as long as your not experiancing an icing problem. If the cycling
times becomes more frequent without anyone fooling with the pressure switch
it's because the refrigerant level has dropped. Then you have a leak in the
system.
