Re: [DML] AC question (might go poof!)

[Warren Wallingford <warren@xxxxxxxxxx>]

It looks like the Freon charge that was new last summer has leaked out 
from somewhere-at least part of it.  Low intake pressure will open the 
cycling switch and the compressor clutch will drop out.  When the 
pressure builds back up, the clutch kicks back in.  A ten second cycle 
time indicates that there's not much charge left.  Find the leak.

The cabin fan is cycling because the 25A breaker is overheating.  It's 
probably original.  Change it out.  Part number 106085. $17.48

I can't be certain of your special noise from the evaportator, but the 
accumulator is connected directly to the evap and it's very near the RF 
wheel.  Take a look behind the wheel.  That may have something to do 
with your leak, too.
