What Is the Purpose of the Capacitor in a GE Refrigerator?

Purpose of a Capacitor

• The capacitor in a GE refrigerator is a device that stores a charge for the compressor. It may be a cylinder or rectangular-shaped element that has conductors extending out from it. The capacitor activates the compressor motor when the refrigerator warms to a certain temperature. It then pushes coolant through the coils of the refrigerator, thus forcing warm coolant away from the GE refrigerator interior. This results in keeping the food at temperature cool enough so food stays safe for consumption.

Indications of Capacitor Problems

• GE refrigerators often last for decades if provided with the proper maintenance and care. If your refrigerator does not keep the food at a cool enough temperature, or it has sections that are warmer than others, this may indicate that the capacitor requires repair or replacement. The thermostat signals the compressor and capacitor to begin cooling down the appliance when the temperature inside the refrigerator reaches a certain temperature. If the capacitor doesn't activate properly, the food may spoil.

Checking Your Warranty

• Before attempting to repair the capacitor yourself, check the owner's manual and warranty to see if service to your refrigerator is still covered. GE refrigerators are covered for replacement or repair on the unit and its parts until the service agreement expires. The warranty typically includes problems with the capacitor. Problems that are not covered often include misuse or abuse of the refrigerator, replacing a fuse or accidents, such as floods or fires in your home.

Discharging the Capacitor Safely

• It is important that you do not attempt to repair or replace a capacitor unless you are knowledgeable about electrical appliances. The capacitor must be discharged before troubleshooting it. Neglecting to do this may cause electrical shocks or burns. These can occur even when the appliance is unplugged since the capacitor stores energy. After unplugging the unit, touch the terminals on the capacitor at the same time with a metal screwdriver with an insulated handle. If the terminals are coated, use needle-nose pliers. This discharges the energy stored within the device. Then you can use a multimeter to determine if the capacitor is working properly.
