If your refrigerator isn't running, an electronic control board failure could be the problem. A service technician can do tests to diagnose the cause. If the electronic control board has failed, replace it following the instructions in this repair guide.

The evaporator fan motor blows air across the evaporator coils and through the refrigerator cabinet for cooling. Replace the evaporator fan motor if it won't run when activated.

The compressor start relay starts the compressor and shuts it off if the motor overheats. Replace the start relay if it's failed.

This helpful refrigerator repair guide explains how to replace the temperature control thermostat in a refrigerator.

The condenser fan is in the machine compartment of the refrigerator next to the compressor. It moves air across the condenser coils to help cool the hot refrigerant coming out of the compressor.

The refrigerator defrost heater melts frost from the freezer’s evaporator fins. Replace the defrost heater if it doesn't heat when activated.

The water inlet valve controls water flow to the ice maker. Replace the water valve if it doesn't open or shut properly.

The ice maker kit is an optional accessory for refrigerators. Install the ice maker kit in a refrigerator that doesn't have an automatic ice maker.

The defrost bi-metal thermostat is a safety device attached to the evaporator coil. The defrost bi-metal thermostat shuts off the refrigerator defrost heater if the heater gets hot enough to damage the evaporator.

Replace the water valve that feeds water to the ice maker and water dispenser if it no longer controls the flow of water.

The run capacitor sends electric current to the compressor motor to help the motor run efficiently. Replace the run capacitor if it's defective.

The defrost thermistor attaches to the evaporator coil and measures the evaporator coil temperature during defrost.

The electronic control board is the "brains" of the refrigerator. Replace the electronic control board if it fails.

The thermistor monitors the temperature inside the refrigerator compartment. Replace the thermistor if it isn't detecting temperature accurately.

The light switch turns the refrigerator light on and off and monitors door position. Replace the light switch if it doesn't work.
