Will a compressor run without freon?
Neighbors 2004 Forest River TT air conditioner is not cooling. Fan, blower runs fine, compressor also as it is hot to the touch. My experience has been if there is no freon the compressor will not run...

Compressor will not run without freon. The low pressure switch shuts it off.
RV A/C units do not have low pressure switches they will run without gas until they lock up or the internal thermal opens up, and yes it will damage the compressor running without gas. They get hot because there is not cooling from the cool vapor coming back form the evaporator (suction line)they lock up because the oil will go out into the system and not circulate back to the compressor with out gas in the system.
