The replacement of this part is normally conducted by a service technician. You should only attempt this replacement if you are completely confident that you can safely complete the repair. Follow electical safety guidelines. Disconnect electrical power before accessing internal components of the refrigerator. The capacitor will also need to be discharged to prevent electrical shock. Internal metal edges may be sharp. Protective gloves are recommended.
Assuming that you have already tested the overload relay and the capacitor is discharged, here is a procedure for changing the part:
First, remove power (unplug the refrigerator) from the wall. Remove the rear cover at the lower back portion of the refrigerator.
The relay overload component is located and mounted on the side of the compressor at the rear of the refrigerator. It will be mounted on the left side of the compressor with the capacitor mounted over it which acts a cover. There will be a wire retainer clip securing the capacitor over the relay/overload assembly. Pry the wire retainer off at one end and remove the retainer. Pull the old relay off and replace it.
NOTE: Make a note of which wires are connected where at the relay/overload and capacitor before removing them.
Reverse the procedure to reassemble.
