Question about Refrigerators

5 Answers

I have a Kenmore side by side refrigerator model # 253.52322200. It starts up and cools fine for awhile, maybe 4 to 5 hours. Then it stops cooling. I think it runs until it reaches the correct temperature then the compressor shuts off and wont restart. There is a loud buzz, which I guess is the overload relay, that buzzes for about 10 seconds then stops. Then it will do it again about 10 minutes later. At this point I have to shut the freezer off and wait about 4 hours before the compressor will work again. What should I do.

    I replaced the defrost timer circuit board as that was my original problem-evaporator coil freezing. Since then the evaporator coil hasn't been freezing but once the fridge reaches the set temperature and the compressor shuts down it won't restart.

  • marc283 Jun 18, 2009

    There is no knob to move. I only have a circuit board to my knowledge. To manually activate the timer I press the fridge light button 5 times in 10 seconds. I have done this before and it starts the defrost cycle immediately but then fridge won't restart. Why would compressor start up fine if it's been off for 4 hours but not restart and overload protection kicks in when its been running for a while?

  • marc283 Jun 22, 2009

    After going on the Sears parts website I have found there is no overload relay listed. There is a starter switch and a capacitor. Perhaps the overload is part of the starter mechanism. If so would I need to replace the capacitor as well?

  • marc283 Jun 24, 2009

    Okay I replaced the relay and it is still doing the same thing. So far I have replaced the defrost timer, defrost heater, defrost thermostat and the relay with no success. What now?





  • marc283 Jun 25, 2009

    Yes it's still buzzing. Not sure about a storm as fridge first went out weeks ago. The compressor fan is running fine. Can you tell if a compressor is overly hot by feeling it? It is 7 years old unfortunately. The one thing that I didn't do that you suggested was buy a capacitor. Could that be causing the problem described? If it is the compressor why would it run so well for so long?


    Thanks for your help!

  • marc283 Jun 25, 2009

    I appreciate the ideas and questions, thanks.


    Not sure if it is getting down to zero. It does get cold enough to freeze water. I'll check the coldest temp once it cools down fully. I just restarted it 1/2 an hour ago. What is suppose to keep the compressor from coming on too soon and how soon is too before it restarts? Well I'm not 100% sure the compressor is running for the entire 4-5-6 hours-it sounds like it- but it takes that long for the overload to kick in. I just turned the unit off and will turn it back on in 10 minutes to see if it starts. Like I said it had been running only 1/2 an hour so I would think the compressor wouldn't be too overheated yet. I just checked the freezer temp it was 32 degrees.

  • marc283 Jun 25, 2009

    Ok I'll check on the temp and the time but will probably have to wait another 4 hours before it will restart. I just tried to restart after shutting down for 10 minutes and it wouldn't. I'll get back to you.


    Thanks again.

  • marc283 Jun 25, 2009

    Thanks I'll let you know sometime tomorrow morning depending on when the fridge is ready.

First, you need to determine what the problem is. Remove the rear cover in the freezer, and check for COMPLETE coil coverage (of ice). If so, the defrost system has failed. If not, then problem is in the sealed system, and should still be under warranty. :)


You have to visually look at the coils BEFORE you defrosted them. You still know nothing about this problem. However, if there was ice forming on those coils, replace both the heater and bi-metal. If that doesn't solve the problem, the board will need replacing. It has an ADC system. :)

Unplug the fridge, and remove the rear bottom panel. Remove the white plastic start device on the compressor, and shake it. If it rattles, replace it (WITH THE EXACT REPLACEMENT/SUB - NOT A 3in1 HARD START KIT). If the relay is ok, the compressor itself is finished. :)

More than likely the main control board has failed. It is located behind the metal panel, on the rear left of the unit. I know of NO way to actually check it. When you replace it, the new board must be programmed properly, or it will not work.



you mean the "motor" is the compressor? If so, and there is no ice forming on the rear freezer wall, the unit has developed a sealed system leak. Very expensive - if it is NOT under warranty, time for a new fridge.


You might have burnt the start winding out by connecting it directly (for 5 minutes). Some compressors (variable speed) cannot have the 3in1 hard start kits installed. If the wires are connected properly, and there is voltage at the kit, the compressor is finished. :)



During defrost, no motors should be running. If the compressor itself is running, but not cooling, the unit has developed a sealed system leak (bad compressor,refrigerant leak), and is NOT economical to repair (leaks CANNOT be fixed whatsoever). I hope this helps! :)







it is possible that it might be in a defrost. I'm a little curious to unplug it to move it back

Hi, It sounds to me like the relay over load switch is going bad. When the relay is buzzing, do the lights in the house dim? This happens when the compressor is going bad because it pulls to man amps. The overload sounds like the issue.

    Hi, Yes the overload and relay come together. I would advise getting the capacitor as well.

  • Victor
    Victor Jun 25, 2009

    If the compressor still has to cool down before restarting, it must be getting very hot. If the condenser fan is running but, not keeping the compressor cool enough, the compressor must be going bad. If the refrigerator under 5 years old, it might still have a warranty on the compressor. Are you still getting the buzzing noise from the relay?

    Since this happened the same time period of the defrost board going bad, is it possible you had a power surge or it happened during a storm?

  • Victor
    Victor Jun 25, 2009

    The capacitor on this model is a run capacitor. It will not help the compressor start. If the compressor is getting weak as far pumping the coolent, it will run a little longer then normal causing the compressor to labor. Do you know if the freezer section is reaching 0 degrees before it shuts down?

    Another possibilty is, once the compressor shuts off, is it trying to start to soon? They are designed for the compressor to be off long enough in the down cycle so it can cool down before starting.

    I know this is a lot of ideas and questions from me but, I just want to help.

    Are you saying that the refrigerator runs the whole 4-5 hours and then shuts down?

  • Victor
    Victor Jun 25, 2009

    Ok, It has to be 0 before the cold control/thermostat will shut the compressor off. If it does not reach 0, the only way it will shut down is the defrost timer or the compressor over heating. Put a thermometer in the freezer and see what the temp is when it shuts off. If the compressor is strong, it should reach 0 in about two hours.

Actually its a defrost timer that is faulty.after every 5 to 6 hours the timer is suppose to put on the heater and off the compresser for a while to defrost the accumulated ice.but if the timer is faulty.it doesnot command the heating procedure and allows to over freeze resulting in compresser shut down.
to restart the compresser again the fridge needs to defrost.so every time the compresser stops you have to off the refigerator for 4 hours and allow the ice to melt.so that the compresser can start again.

to solve this problem.you have to replace the defrost timer / it will cost approx 35 dollars.its a very common problem and gets solved easily.nothing much to worry.

keep updated,thanks.
please do rate this solution positively

    two things to be done:



    1) initially try manual timer reset.which means put on the timer to defrost position by moving the knob manually.this time it actually wont defrost the ice but will reset the timer position .this is called a false command method.by the next defrost timing the fridge will automatically fix all the defrosting and other problems.



    2)sometimes the relay is working but is at the end of its life.if the manual reset method doesnot help,then replace the relay to fix this issue.



    keep updated,thanks.

Hi,

First of all make sure that the compressor and fans are working.

Check a link below :-

http://www.applianceaid.com/frig_notcold.html

http://www.applianceaid.com/refrigerator.html#clicking

The 2nd link would describe , an error more likely a relay. These might not be for your model. It's for generic refrigerators. To make sure, you have the correct solution, i have introduce the links i have.

Any further help, ask at any time.

Thanks for using "Fixya".

Kenmore model 596.71103101 stopped working. No sounds at all, no cooling. Un plugged for awhile, plugged in, still nothing, cranked freezer control to Max, started working


Sounds like a defective cold control thermostat. Remove the wires from the thermostat and jump them together. If it runs continuosly for 45 minutes, replace the thermostat.

Refrigerator not cool, freezer ok


Either the freezer continues to freeze up (most likely due to low refrigerant, due to a leak), or there is an obstruction between the freezer and the refrigerator (refrigerators get their cooling from the freezer).

Given that it works after you defrost it, I'm going with low gas. Call a professional to see if the leak can be fixed. If the unit is more than 10 years old, just get a new one.

Freezer works Refrigerator will not cool down


The compressor should be OK this time because you caught it in time. But if the condenser fan stops you need to consider replacing the fan. I have had refrigerators do fine until the fan motor warms up and you are away, it stops. Don't think you should use the refrigerator until the fan is fixed. Sea Breeze

Kenmore fridge stopped cooling


sounds like its freezing up on you. check the drain outlet and make sure that its clear. also i would replace the defrost timer on this unit because its suppose to bring on the heaterfs to melyt the ice so thaat yoiu don't have to. they are around 30 mdollars at the appliancew repair store and all you need is the model number and serial number for the uit. after you get it it's either on the very top of the refrigerator section or in the very back. It has 4 wires going to it. good luck.

My Kenmore side by side stopped cooling


I think your compressor has given up the ghost. Yes it is possible that it could be a relay problem but not likely.
