Connect the high pressure side to the Freon pump to the propane canister sitting in a pail of ice water. Start the Freon pump. The pressure reading of the refrigerator high pressure line will drop as the propane canister becomes heavy with condensed Freon liquid. Close the propane canister and deliver it to an air conditioning professional for recycling. If you found the refrigerator pump does not work, it can be replaced.
Installation is the opposite of removal.
Mount the new refrigerator pump on its rubberized mounting brackets within the refrigerator frame. Match up the high pressure and low pressure Freon lines and solder them in place. Reconnect the 120 volt ac power lines. Cut the old dryer out of the high pressure line and solder a new drier in place. To test the repaired refrigeration system for leaks, see how well it can hold a vacuum.
