What does evaporator fan do?
The evaporator fan is responsible for keeping a constant flow of air in the refrigerator box. It must keep the air moving and flowing over the evaporator coils so the refrigerant can absorb the heat from the box.
How does a condenser fan work?
How Does it Work? While the condenser unit works to cool the air conditioner while it’s running, the fan motor functions to blow the air through the condenser coils to convert hot, refrigerant gas into a cool liquid. As the fan blades turn, your air conditioning unit will continue to blow cool air in the entire house.
What happens if the evaporator fan goes out?
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.
Will refrigerator work without evaporator fan?
The evaporator fan is responsible for circulating the cold air from your coils and into the refrigerator section. Without it working, the cool air will not be efficiently blown onto your fresh food. However, your refrigerator will still try to maintain that temperature by instead just running all the time.
Does evaporator fan run all the time?
The evaporator fan is not supposed to run all the time but until the refrigerator reaches a set temperature. However, it runs in combination with the condenser and compressor fan. When the fan runs without any break, it causes air to circulate properly. This will produce an even temperature throughout the refrigerator.
Why do condenser fans fail?
There are several reasons the capacitor of your HVAC unit can fail. These include overheating, running too long, power surges, and age. When the capacitor fails, the condenser fan will no longer rotate.
What does a bad evaporator fan sound like?
If it sounds like squealing or a bird chirping in your fridge. Your fridge shouldn’t sound like a bird or small critter is trapped inside. If you do hear noisy refrigerator sounds like squealing or chirping, it may mean the evaporator fan is malfunctioning.
Does freezer fan run all the time?
The fan motor in the freezer will not run all the time, it will cycle during a defrost mode and when the unit cycles through the cold control on most models.
What happens when refrigerator condenser fan fails?
If the condenser fan does not function properly, the refrigerator’s temperature can rise and the compressor can overheat.
Why is my evaporator fan not working properly?
If the evaporator fan doesn’t run in the diagnostic test mode, then you could have a defective control board, but the problem could also be a bad evaporator fan or a break in the wiring. Let’s check the wiring first. Unplug the refrigerator and remove the screw that holds the control box.
What does an evaporator fan do in a refrigerator?
Hi, this is Wayne from Sears PartsDirect. The evaporator fan is this little device back here that blows cool air into your refrigerator and freezer. Typically, it should run whenever you hear your compressor turn on. Today, we’re going show you a few things to check if your evaporator fan motor isn’t turning on.
How to check continuity on an evaporator fan?
To check for continuity, put the meter leads on either end of the red wire with the white stripe, one on the evaporator fan plug and the other on the control board plug. The meter should read near 0 ohms. Next, check for continuity through the light blue wire in the same way.
How does an evaporative condenser system work?
How do evaporative condensers work? The vapor that is about to be condensed will circulate through a condensing coil. The outside of this condensing coil is repeatedly wetted by a recirculating water system. A small portion of the recirculating water evaporates when the air is pulled over the coil.
