	That was a pathetic response. Are you really that dumb? All of your posts have the same old sh1te and it is sad. Are you trying to be cool or funny? Either way you are failing. What is with the "<Splutter>" that you put in all your posts? Perhaps you should change your username from Stinky Pete to Stupid Pete. Del

	Dear guest, I don't understand "the motor runs with the pump off" most scroll compressors are sealed with the motor direct driving the compressor (oump?) It appears that the motor IS driving the compressor as it should. Did you also change the expansion valve? You should check the cut out pressure using a normal mechanical guage and check it against any read out you may have. If the compressor runs and cuts out at the predetermined pressure and while it is running, check to see if there is ice forming on the outlet of the expansion valve and at the outlet of the evaporator. Check to hear if the expansion valve is noisy (rushing sound), if so, the system is short of refrigerant. If no ice or cooling at the evaporator outlet and ice/cooling at the expansion valve, faulty/blocked expansion valve. NEVER change the direction of a previously run scroll compressor, you may have already damaged it.. Good luck Phil
