    Got a dumb question if you do.

    Removed a Freezer Evaporator Cover Louver while I was troubleshooting some noise. The freezer instantly got quieter, I assume from the air moving more freely, allowing the motor to not work as hard. Wondering what the downside is to just leaving it off entirely. Yes, I know there would be gaping hole in the back of the freezer. ha.

    Why yes, as a matter of fact I don't.
    Thanks for asking!

    Not by a human being, but I found the hard way that some temperature regulation issues developed in the freezer so I had to put the louver/vent back on. Thanks for asking!

    The louver directs air flow in a certain direction and removing it could possibly lower efficiency of the refrigeration.

    Noise abatement is an issue, but is there any other way?

    Yes I was concerned that might happen, and it did. There is a small attachment directing air flow towards what I assume is a sensor.

    I could put the 'fridge in a sound proof isolation room, or just suck it up and live with it. :)

    The fridge is about 6 years old now. It's a Whirlpool, purchased brand new. Over the last few months one of the motors has gotten a bit louder. I believe it's the freezer motor but it's a bit hard to localize the sound. Not so bad that something sounds broken, it's just humming louder so I started poking around. Could be normal wear and tear, but as a test I removed the louver/vent in the freezer and interestingly things got quieter. It's not that the louver itself was vibrating, it seems as if removing it allowed for better air flow and the freezer motor didn't have to work as hard, quieting things down. However as I noted in my last post removing the louver seems to have toyed with temperature regulation in the freezer so I reinstalled it. I had also popped the front and back panels /vents off and vacuumed everything out to no avail.


    Thank you

    If you still have the noise try going to home depot or lowes get a coil cleaner for cleaning the coil it may be plugged if you have an air compressor try back blowing it out if that doesn't help then I would say you need to replace the motor as it could be wear on the bearings witch is what I think it is you have to figure that the fan runs 100% of the time never shutting off also make sure that coils on back or underneath are clean airflow is critical hope this helps

    Try freezing the refrigerator in liquid nitrogen(?)

    Or leave the louver off and adjust the thermostat to compensate for the erratic temperature regulation maybe?

    I dunno, but if my beer is cold, I'm good with it.

    The issue is back-pressure.
    The louver slows the air flow, and because of this the air becomes colder.
    Then the louver directs this cold air in a certain direction.
    Without this, the control of air movement is disabled.

    I had a fridge that was noisy when the compressor was running. It turned out to be that the four feet that held the compressor in place were bolted to the chassis and each of the four points had cushions that had rotted. Whatever means it was bolted down with made them non-adjustable/non-repairable. It probably coulda gone on for another 10 yrs, but I eventually got a new fridge.

    What LRT#1 said very important to keep all the coils and underside clear can cause it to run hot or harder than it should:agreed:
