Gary,

The low speed on a 2 speed system can be very noisy and mislead the owner into thinking it's the fast speed.
If your condenser is low efficiency and/or you have a low refrigerant charge (but not low enough to disable the compressor) the fan will still start at low speed then, after a time, increase to fast.

No. Chuckles says that to ultimately solve his problem the condenser was replaced. That makes sense. The desiccant's purpose is to absorb any moisture in the refrigerant. It will not completely stop the system cooling.

You need to check your refrigerant charge otherwise you could waste time and money on unnecessary repairs.
