The Evaporative Fan on My Refrigerator Is Not Working

An evaporative fan is a part of a home refrigerator unit that helps to chill the internal storage areas. The fan works by creating cold air when it changes liquid water into a water vapor, which uses less energy than other forms of refrigeration. However, when this part of the fridge fails, it can cause the internal temperature of the fridge to rise and promote food spoilage. When the evaporative fan fails, several parts of the fridge can be to blame.
  1. Compressor Check

    • Check the compressor to ensure it is working. If the compressor is running but the fan is not, you might have a freon leak in the coolant portion of the compressor. This can't be replaced by people inexperienced in home repairs, so call in an expert. If the compressor is not running, the motor might have failed and should be replaced.

    Condenser Coil

    • Check the condenser coil with a voltmeter, and then with a multimeter set to ohms. If the coil reads 120 volts, but the multimeter reads over 0 ohms, an open circuit is on the compressor and the pins in the relay might need to be replaced.

    Defrost Timer

    • The defrost timer control can cause the failure of your evaporative fan. To tell whether the timer is faulty, confirm that the fan is not getting voltage with your voltmeter, and that the compressor is running.

    Fan Rust

    • Over time, the water vapor created during the cooling process can create rust or corrosion on the evaporative fan. If the fan is stopped and does not start up when you tap it, rust might have caused the motor to seize up and it should be replaced. Wear heavy work gloves to protect your hands when tapping the evaporative fan, just in case it kicks back on.
