The fan forces environmental air through the condenser, aiding the transfer of the heat of compression from the coil to the ambient air. An inoperative fan not only causes the cabinet temperature to rise but causes the compressor to overheat, which leads to its premature failure and a costly repair. The fan can pull in dust that, over time, will coat the condenser. The more dust and grime on the coils, the less efficiently the condenser can operate. The result is a condenser that must run almost constantly in order to keep the refrigerator cool. The fan will run as much as the condenser for the same reason. The fan runs whenever the compressor runs, and it draws cool room air through the front grille, and circulates it through the condenser coils, over the compressor, and back out the front grille into the room. The circulating air helps cool the compressor and the refrigerant in the condenser coils. Signs and Symptoms of a Bad AC Fan Motor The fan won't start even though the AC is on. The fan won't stop, even when you shut the AC off. The fan turns on, yet the blades are rotating very slowly. There's a rattling noise coming from the condenser unit when the fan is turned on.

A common reason a condenser fan is continually running within a refrigerator is the thermostat. A basic test is to set the thermostat on the warmest setting; if the cooling unit continues to run, even when it's being told to keep the fridge warmer, you have a broken thermostat.

Condenser coils are located on the back of the fridge or across the bottom. These coils cool and condense the refrigerant. When the coils are clogged with dirt and dust, they can't efficiently release heat.

Feel for cold air in the freezer. If the evaporator fan motor stops working, your freezer will begin to defrost. Most freezers don't run the evaporator fan motor when the door is open, so if the fan does work, it will turn off when you open the door. Check the temperature setting on the freezer to be sure it's on cold.

Normally the condenser fan motor should be running when the compressor is running. Power ( 115 volts AC ) to the motor and it is not running is a bad fan motor.

A slow condenser fan (or air handler unit fan) could be caused by a bad start-run capacitor. Unfortunately this condition could indicate a burned-out A/C or heat pump compressor motor. This can leave the fan motor running. A bad fan motor can also cause the fan to turn but only abnormally slowly.

One of the signs that a compressor is failing is that it runs continuously without the refrigerator and freezer compartments reaching their proper operating temperatures. This condition may be the result of a loss of refrigerant in the system, or the compressor's valves may be failing.

The evaporator fan motor draws air over the evaporator coils and circulates it throughout the freezer. To compensate for the decrease in cooling capacity, the freezer will run continuously in an attempt to keep the freezer cold. If you suspect that the defrost heater isn't working, first check the evaporator coils.

Clogged coils can cause poor cooling. Check to make sure nothing is stuck in the condenser fan and that it spins freely (models with coils on the back won't have a fan). To do this, unplug the fridge and pull it out. Plug in the fridge and make sure the fan runs when the compressor is running.

This evaporator fan motor circulates air over the refrigerator coils. This evaporator fan motor is located in the back of the freezer, and circulates air over the refrigerator coils. These coils will convert the heat into cool air, which is then circulated.
