    Default Frigidaire Refrigerator Not Cooling

    Hi All,

    I have a Frigidaire FFTR1821QS4 refrigerator. A couple days ago, the motor or compressor started running much more quietly than normal and the interior light stopped working and the fridge stopped cooling.

    I had a service person come take a look at the fridge. He said he wasn't sure exactly what the problem was. Using a multimeter, he found that the control box (part# 5304507171) wasn't working, but said that he wasn't able to test the compressor b/c the control box wasn't working and that when the control box was replaced I might end up also having to replace the compressor. If I had to replace the compressor, he intimated, I might as well buy a new fridge.

    I have a couple questions:

    1) Is it possible that the only issue is the control box? Based on my research, the control box seems to regulate temperature. But in my case, the fridge isn't really cooling at all.

    2) Is it true that one cannot test the compressor if the control box isn't working? I ask b/c I simply want to make sure that I'm not being fed some BS.

    Thank you.

    But it WAS still running?

    You can still ohm the compressor windings, you could still run a test cord directly to the compressor....if there was no power coming to the compressor ( then it shouldn't be running ) then the control box is the suspect.

    I'd try the control....but I came up with a different part# using your model#...

    Yes, my understanding is that it was still running (albeit at a lower level), just not cooling. I was not actually present to confirm one way or the other.

    So, if I'm understanding you correctly, the serviceman could have tested the compressor to confirm that it is still working?

    Thank you. Where did you input the model number to get the part#? I'm a newbie.

    We can test it yes....would not tell us if it is going to work properly under a normal working load but would still give us a good idea if it is bad or good.

    I looked it up on the parts breakdown...

    I picked #21 which subbed to the one I linked to above.

    Update: So I replaced the control box, and the fridge is still not working. Neither the light nor the motor are turning on. Basically, I plugged the fridge in and nothing happened.

    Any suggestions on what part to try next?

    I also got some additional info from the folks in the apartment. They said that initially the motor started running more quietly and the light went off and the fridge stopped cooling. But they added that within two hours or so, the motor had stopped running as well. When i plugged the fridge in today, the motor was still not running.

    I also noticed that the fridge door does not close properly unless you lift it up a little as you're closing it. Not sure if this would over-work the fridge or something, since cold air can easily escape.

    How long did you leave it plugged in....many have a delayed start in case the power ever went off and than came back on the refrigerator won't start until it has sat for maybe 5-10 minutes. This could stop the compressor but shouldn't stop the light from working.....has the bulb been checked?

    Did anybody check for power at the compressor?...if yes, what was the readings?

    I also noticed that the fridge door does not close properly unless you lift it up a little as you're closing it. Not sure if this would over-work the fridge or something, since cold air can easily escape.
    Cold air falls so an opening at the top will likely not leak out cold air but could leak in warmer room air and cause the over working like you mentioned.

    I left it plugged in for maybe 5 minutes max, definitely not 10 minutes. But, as mentioned, the bulb did not go on. And yes, I did check the bulb in a lamp to confirm the bulb isn't the issue.

    No. I will ohm it tomorrow.

    So if the refrigerator failed due to being over worked, is there any likely part that would've failed? The compressor? But would a faulty compressor keep the light from working?

    Thanks for your help, Jeff. I'm really hoping I can avoid buying a new fridge. This one is not even a year and a half old

    The light and compressor are different systems and normally not related to each other.....only thing I can think is the power for both and that is the control board ( which you already replaced ). The new part could be bad, but doing the exact same thing as the old one is would be rare!

    And yes, I did check the bulb in a lamp to confirm the bulb isn't the issue.
    Probably a good idea to check the light switch then.

    Did anybody check for power at the compressor?
    No. I will ohm it tomorrow.
    Volts/power ( 110-120 volts AC ) when it should be running.

    A copy:
    START-UP NOTE: Upon 1st start-up or power cycle, the compressor will come
    on after 12 seconds and run for 115 seconds. If the door switch is not cycled
    during this time, the compressor will cut off after 115 seconds and not turn
    back on for another 5 minutes. It may take up to 10 minutes for the compressor
    to turn on and run in normal mode.

    Jeff, does that board have start and run capacitors in it? Have a reason I am asking as this post makes me think of what sounds like a similar problem.
    Not the light, but the light and motor seeming to run at low voltage or speed.
    I intend to post my problem in a new post.
