Air Flow. The condenser in a refrigerator is a motor, and like the one in your car it needs constant airflow to remain cool enough for the working parts to remain in working condition. … This forces the condenser fan to work continually to try and disperse the heat.
Should the fan in my freezer always be spinning?
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. I have been unable to retrieve a wiring diagram to confirm the control cycling on your specific model.
What does an evaporator fan do?
An evaporator fan draws air from the refrigerator and blows it over the evaporator coils. The liquid refrigerant absorbs heat from the air and the air blows back into the refrigerator at a lower temperature, cooling the refrigerator. … As the heat is released, the refrigerant turns back into a liquid.
What happens when refrigerator condenser fan fails?
If your condenser fan stops, the temperature of the refrigerant will rise and the compressor may overheat. … 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.
How often should a freezer fan run?
You need to make sure that your freezer’s run time is normal, that it is cycling on and off about every 30 minutes, and is running about 80-90 percent of the time. This will not only extend the life of your freezer but will actually help to cut energy costs.
Why is my freezer fan not running?
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.
Why won’t my freezer shut off?
If your freezer doesn’t shut off even though the desired internal temperature has been reached, you may have a problem with the temperature control thermostat. … If the contacts weld or stick closed, or if the sensor bulb is damaged, the compressor will continue to run regardless of the temperature.
How do I know if my evaporator fan motor is bad?
Listen for a squeal or chirp sound. If the evaporator fan motor is going bad, it may still run while making a high pitched sound that may come and go. If you hear that sort of sound, something may be caught in the fan blades or the motor may be dying.
When should the condenser fan run?
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.
Why is my freezer fan running all the time?
If your freezer is continuously running, then one of the most common causes is the freezer door or lid gasket (depending on your model of freezer). The door or gasket creates an air-tight seal and if it’s damaged in some way it will leak air and the freezer’s compressor will then run continuously to compensate.
How do I know if my freezer thermostat is bad?
If food freezes inside the fridge or its compartments, the cause may be a faulty thermostat. You can use an appliance thermometer to check the thermostat, or try increasing the temperature a couple of degrees. Then wait a day to check whether the food has become unfrozen.
What should your freezer temp be?
Keep your appliances at the proper temperatures.
Keep the refrigerator temperature at or below 40° F (4° C). The freezer temperature should be 0° F (-18° C).
How do you know if your freezer is working?
If your freezer works perfectly, the object should remain on top of the ice. If the freezer stops running over a longer period of time, suggesting a possible malfunction, the ice will melt. Your object will be enclosed in the ice – or even drop to the bottom of the container.
Can fridge work without 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.
What controls the evaporator fan motor?
An evaporator fan controller monitors refrigerant flow or compressor drive motor amps and reduces the speed of evaporator fans when the compressor is off.
How many hours does a freezer run per day?
Step Three: Most “average” refrigerators run for about eight hours per day. Multiply 8 hours of usage by the number of watts you came up with in step two, or 8 x 960 = 7,680 watts per day, on average.
Should the condenser fan always run when the AC is on?
The fan only runs when the system is on and not continuously. There is better dehumidification in your home during the summer months. When your fan is set to AUTO, moisture from cold cooling coils can drip and be drained outside. If your fan runs continuously, moisture does not have a chance to drip outside.
How important is the condenser fan?
The condenser fan motor plays a vital role in how well your HVAC system works, and is located within the condensing unit. Its purpose is to transfer heat from the refrigerant system into outdoor air, which keeps the compressor from over-heating.
What would cause a refrigerator to stop getting cold?
Vacuum the coils under or behind the fridge. 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.
What happens if you turn a freezer on too soon?
The level of caution you choose to exercise will be entirely up to you, but be warned that blockages in your system could occur – impacting the cooling capacity of your appliance – if you switch it on too early, so it’s always best to leave it for as long as you possibly can up the 24 hour mark – especially if the …
