Tyler Z., Home Appliance Technician. This can be caused by a bad defrost timer, defrost thermostat or defrost heater. Enter model number to search for the required part specific to your product. If the freezer isn’t working, you should be able to tell quickly. Once you de-frosted it, the pump had to go back to working the way it was supposed to do, and the fan did as well. The evaporator fan should cycle on and off but it will cycle differently then normal. The condenser fan motor should run any time when the compressor is turned on. Selecting the ‘on’ position will mean the fan is always on. (It is just over 10 years old). However, even if it did run constantly, this is a low voltage dc motor that takes very little (almost no) current. Click here to add your own comments. If your refrigerator isn't getting cool, the fan is just one of many possible reasons. With this style it can seem like the motor is always running. I also followed through your video.

It enables the fridge to achieve the best cooling effect and keeps your foods or beverages always cool enough for your consumers. Sounds like you have a defrost problem. Gaps in the door seal permit warm, humid air to enter the refrigerator. Although the evaporator fan is running, we don’t feel the cold air blowing into the refrigerator. The answer isn’t always simple, but the first step is understanding the three major risks that are offset through constant, full-speed fan operation. These same diagnostics also aid in air conditioning blower assembly diagnosis when an A/C blower continues running. Hi guys, I was commissioning a freezer 6M X 3m, -18°c today, While watching the temp dropping and adjusting the super heat and head pressure, a thought came to my little brain, In a freezer room, if the unit is not in defrost mode, the fans work all the time. Satisfied Customers: 104,210. The unit seems to be cooling and the compressor and condenser fan are cycling in normal intervals, but the evap fan won't shut off.

The unit will run OK for a few days till the evaporator coils again get clogged up with ice/frost again. Evaporator and Condenser Fan Motors: The back panel of the freezer is also where you'll test or replace the evaporator fan motor. When the unit have reached the set point, it stops. 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. This creates a domino effect of problems, including evaporator coils that accumulate frost faster than the heater can remove. Here are some of the most common causes of this problem to help you do a little AC troubleshooting: Dirty evaporator coil. It must keep the air moving and flowing over the evaporator coils so the refrigerant can absorb the heat from the box. I have noticed that since Saturday, the evaporator fan on my Kenmore side by side has run continuously. Check the two non-ground wires, they may be red and grey, for continuity, looking for a positive ohms reading. The coolant moves from the condenser where it is cooled into the evaporator. The evaporator fan is responsible for keeping a constant flow of air in the refrigerator box. A: The function of the evaporator fan motor in the refrigerator is to enhance the circulation of cold air inside the cabinet to maintain an even temperature. ACs cool and dehumidify your home in the warmer months. If the freezer is cold, there likely isn’t an issue with the evaporator fan motor. Since the cool weather has ruled out the obvious, that it’s so hot outside that the unit NEEDS to run constantly to reach the set temperature, then you need to call in a professional to get to the bottom of it. You are talking about the condenser fan motor not the evaporator fan motor correct? Why Does My Refrigerator Run All the Time? Does this sound like something we need to pay a repairman to come in and look at, or should we just replace the whole thing?

Unplug the refrigerator and remove the screw that holds the control box. The function of the fan is to push (or pull) cool air across the coils connected to the refrigerant pump to cool them down (thus shedding the heat that's pulled out of the inside of the freezer).
The evaporator fans continue to run and circulate the air and slowly heating the room. 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.
