yes, it will protect the compressor... because ice starts forming, and the freeze switch cuts out the compressor before the ice builds up. but it also keeps the cabin from getting cool.

if the evaporator is clean, the freeze switch won't cut out the compressor, because the airflow through the coil is greatly increased... so the compressor runs longer, and the pressures build.

look, you're arguing with me while you are agreeing with me without knowing it.
