This DIY repair guide has step-by-step instructions for replacing the compressor run capacitor in a top-freezer refrigerator. The run capacitor continuously sends electrical current to keep the compressor running. If the house circuit breaker for your refrigerator trips as soon as the compressor tries to start, the run capacitor could have shorted out. Replace a shorted run capacitor with a manufacturer-approved replacement part.
Note: In refrigerators with an optional capacitor, the compressor starts and runs even if the capacitor isn't getting electrical current. A failed optional run capacitor won't keep the compressor from running, but it shortens the life of the compressor. Over time—probably a few years—you might notice the compressor motor overheating and clicking off.
This repair procedure works for Kenmore, Frigidaire, Electrolux, Whirlpool, KitchenAid, Maytag, Amana, GE, Samsung, LG, Gibson, Crosley, Bosch and Haier refrigerators.
