ISSUE:
A "refrigerator type smell" or "chemical type" odor may come from some A/C systems. As the calibration of the clutch cycling pressure
switch drifts downward, the evaporator core temperature may drop too low. This results in a "refrigerator type smell" or "chemical type" odor
as the system cycles on and off.
