How to Replace a Refrigerator Condenser Fan Motor - YouTube Repair Difficulty. [00:09] Before you begin. [00:26] Shut off the power. [00:30] Remove the condenser fan motor. [00:36] Install the new condenser fan motor. [00:52] Reinstall the rear compartment cover. [01:04] Restore electrical power. A new condenser fan motor can be obtained from the refrigerator manufacturer or a local appliance parts distributor. When ordering the new motor, supply the company with the make and model number of your refrigerator. Condenser fan motors cost between $40 and $60. A common reason a condenser fan is continually running within a refrigerator is the thermostat. This sensor takes readings from the refrigerator (and freezer if you have one) and flips the cooling system on when it sees the temperature isn't where it needs to be. 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. 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.

The condenser fan motor blows air across the condenser coils to remove heat from the hot refrigerant coming out of the compressor. The cooled refrigerant then moves into the evaporator. If the condenser fan motor doesn't run when activated, the air in the refrigerator becomes too warm.

If the refrigerator runs constantly, the evaporator fan motor might have failed. The evaporator fan motor circulates the cold air from the coils thru the compartment. If there is only one evaporator it is in the freezer side. If the fan is not working, no cold air will get to the refrigerator compartment.

Physically Obstructed. If the fan is not running, unplug the refrigerator and remove the evaporator fan cover. In many cases the problem is do to the fact that the evaporator fan cannot operate freely due to an ice buildup on the fan blades. If the problem is bent fan blades, replace the fan blade.

Where It's Located: The condenser fan is located in the bottom cabinet by the compressor and the condenser coils. It is important to note that refrigerators with condenser coils on the back will not have a fan.

Normally the refrigerator condenser fan and compressor, located near the floor on the back of most refrigerators, come on when the thermostat calls for more cooling.

A condenser fan motor is part of your HVAC system that is located within the condensing unit. This unit also consists of the compressor and condenser coil. The outdoor unit works to keep the air conditioning unit cool when it is running.

How to Test a Condenser in a Small Engine Remove the condenser from the engine. Switch the volt ohmmeter to the ohms position. Touch the red lead to the hot connector on the condenser. Remove the leads and reverse the placement to the condenser. Movement from the meter's needle indicates the condenser is good.

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. On most refrigerators, the fan motor will not run when the door is open. The defrost heater turns on several times throughout the day to melt away any frost that may have accumulated on the freezer evaporator coils.
