The direction in which a vent fan's blades rotate has an impact on its ability to function properly. If not, either your fan blade is bent the wrong way, or it's the wrong blade. This is why airflow is so important inside the fridge. When I looked at the back of the refrigerator, I could so that the condenser fan was no longer spinning. This seems to be contrary to the way the air moves through the front grill. Any other thoughts? If it is not working properly one or more parts of the cooling system will not function. Since the freezer is so much colder than the food compartment, most of the cold air that is produced circulates to the freezer compartment. Help. To prevent too much frost from collecting on the evaporator coils, a self-defrosting refrigerator will actually stop itself for a few minutes every six to twelve hours or so, and melt its own frost. The best way to clean that is to shut it off drape wet towels over the condenser and blow high pressure air back through the coils, wow look at that dirt. If all the frost melts before the defrost timer finishes the defrost cycle, a TERMINATING THERMOSTAT will keep the defrost heater from overheating the evaporator compartment. Nos. The evaporator is SO cold that the humidity from the air will freeze directly onto it, creating FROST. Eventually it will evaporate away. but did not give much thought to where the hot air would exit the housing. Valterra Black RV Refrigerator Fan. The condenser fan runs in a counter clockwise direction. All these type motors turn counterclockwise viewed from the back. I am mounting the fan onto the condensor motor with the fan facing towards the back of fridge. The tech had to cut the connector off the replacement motor and re-connect using screw type wire connectors. Thus, when you put warm food into a cold refrigerator, heat starts flowing from the warm food into the cold air around it. The condensing unit typically has a fan that draws air across the coils to facilitate the needed heat transfer to insure the unit is operating efficiently. This one is less than 3 years old!! Depending on the model and make of the refrigerator, it will have air vents in a few spots. He said that the flow was toward the compressor (or the left viewed from the back of the refrig). TO something of a LOWER temperature. The refrigerator condenser fan plays an essential role in the refrigeration cycle, but not all … Move the Fridge Inside an Alcove. On some models, the warmth from the condenser is used to evaporate the defrost water. In some models a CONDENSER FAN is fitted to circulate air across the condenser. Powerful. After the Freon loses the excess heat in the condenser, it is de-compressed, or expanded, by simply putting it through a constriction that lets the pressure drop. A typical configuration of such a condenser … Fans are not used to remove heat from the compartment, they are only used to increase air flow through the condenser fins.Most RV refrigerators need the increased air flow when the out side temps reaches 85 degrees or higher. It could have simply continued the existing air direction but I didn't think that would help much so I arranged it to also draw air in on that side, over the condenser etc. Better distribution and removal of heat and the entire condenser gets some benefit from it. I suspect maybe a fan blade may be the problem. I''ve been told it should run in a clockwise position, and to switch to obtain the clockwise position. It was no longer cooling. I have Samsung Refrigerator model # RF260BEAESR/AA . (The temperature goes down.). On most fridges, all the cold air for both the food compartment and the freezer compartment is produced in one evaporator. 6,792,769 and 7,024,878). the frig will still work if the coil cooling fan stops though it will work harder and could shorten compressor life. Gene, The fan motor is extremely noisy. (in toward the condenser coils and out over the pan) Can you help with this question. When I removed the back panel to the refrigerator, the condenser coil fan was not running at all, and the condenser was hot to the touch. Could it be an out of balance fan blade? This video will walk you through refrigerator fan motor diagnostics for GE electronic refrigerators. Electrical Elco Motor 5/10/16/18/25W for Condenser and Evaporator/Evaporative Cooler Fans/Green House/Air Curtains/Machine Cooling Fan FOB Price: US … A tech just replaced the condenser fan motor and I asked about the direction of the air flow through the fan. Air moves at a speed of 1-3.3 m/s. if you have some fans then place a small fan(s) on the floor in the rear blowing air in the direction the ailing fan does. When the compartment reaches a certain temperature, the terminating thermostat will open and shut off the defrost heater. In thinking about the way your refrigerator keeps things cool, there are a few seat-of-the-pants thermodynamic laws that you need to consider: 1) Don't think of your refrigerator as MAKING THINGS COLD. Does it make any difference which way the fan blade is mounted on the fan? This amount is adjusted by a small AIR DOOR in the duct between the evaporator and the food compartment. This second fan helps provide more even cooling, and also aids in the defrost process. I was a new blade that came with the replacement motor. You can not reverse the leads because the wire harness plug can be plugged into the motor only one way. One is under the refrigerator to cool the compressor and force air through the exterior coils. It is wired in series with the heater. To enable all features please, YAF.NET © 2003-2021, Yet Another Forum.NET. Built-in thermostat. until their temperatures are equal. Depending on how old your unit is, you may have rear refrigerator coils or the cooling coils may be on the bottom of the unit. If I am standing behind the fridge and facing the fan it will be spinning in a counter clockwise direction. Heat Transfer and Air Flow in a Domestic Refrigerator 447 (horizontal/vertical, top/bottom of the compartment) determines the location of cold and warm zones. In order to re-use the Freon for cooling more air, the heat that WAS in your food and is NOW in your Freon must somehow be gotten rid of.
