How to Switch Out a Refrigerator Compressor

The compressor in a refrigerator functions somewhat like the engine in an automobile. Its purpose is to provide power to the internal components and keep the coolant running through the unit. You can pay a professional to replace a damaged compressor with a new one, but you have another option. If you aren't intimidated by working with large appliances, you can replace the compressor yourself.

Instructions

- 1
  Unplug your refrigerator, and remove the perishables from the unit.
- 2
  Move the refrigerator away from the wall so you have access to the rear panel. The rear panel usually is located near the bottom of the back of the refrigerator.
- 3
  Remove the screws holding the rear panel in place with your Phillips screwdriver. Remove the panel, and locate the football-sized compressor.
- 4
  Locate the copper suction and discharge lines. Cut them with your pipe cutter about 2 inches from where they connect to the compressor.
- 5
  Unplug the capacitor wiring harness from the side of the compressor.
- 6
  Remove the bolts on the mounting brackets at the base of the compressor. Remove the compressor.
- 7
  Place the new compressor in the compartment, and replace the mounting bolts.
- 8
  Connect the copper lines running from the compressor to the refrigerator lines. Put on your safety goggles.

  Put a line of solder over the area where the ends of the piping meet. Turn on your blow torch and fire the ends of the piping together, using the solder to bind the ends.
- 10
  Plug the wiring harness into the side of the compressor, and replace the rear panel.
