Question about Refrigerators

1 Answer

Recently, the fan and compressor stops running for periods of an hour or more for no apparent reason and then starts back up. An appliance repairman could find no problem with the refrigerator.

Bottom freezer stopped working, then started working. Would this be a problem with the thermostat or blower fan? During this period refrigerator half had no problems.


Hello Steve:

My name is Peter. I am a retired field service refrigeration technician.
You do not have a problem. It sounds like your refrigerator is running normally.
Your compressor and fans will run based on the cooling demands set by you on your temperature settings. Once the temperature has been reached your compressor or fans will stop running.
If your compressor is running all of the time then you have a cooling problem.
You refrigerator will also shut down about every 8-10 hours for about 15-20 minutes. This is when your refrigerator goes into the defrost mode. Your refrigerator shuts down and the heater around the cooling coil turns on to defrost the cooling coil. This is where the term; "Frost Free", comes from.

GE Side-By-Side Refrigerator Stops Cooling


HI,

If the refrigerator isn't cool, you need to answer some questions, then see if the compressor is running.

First, answer these questions:

  • Is the refrigerator completely dead? If so, see “It's stopped completely.”


  • Is the thermostat knob turned to the proper setting? If not, reset it.


Next, see if the compressor motor is running

The compressor is a football-sized case with no apparent moving parts. It's on the outside of the refrigerator at the back near the bottom. If it is humming or making a continuous noise and your refrigerator is still not cooling, there may be a more serious problem with one or more of several different components, we recommend contacting a qualified appliance repair technician for further help.

If the compressor is not running but you do have power to the refrigerator, there may be a problem with one or more of these:

  • The compressor


  • The Thermostat


  • The overload, relay, or capacitor


  • The defrost timer


  • The condenser fan motor


Cooling is poor For an overall understanding of how refrigerators should work, read about refrigerators in the How Things Work section of our website. A refrigerator or freezer that is cooling, but cooling poorly, may have a problem in one of several areas:

Evaporator coils
Condenser
Poor cooling is often the result of a heavy frost build-up on the evaporator coils or a condenser that is clogged with dust, lint, and dirt.

Evaporator coils Poor cooling is often the result of a heavy frost build-up on the evaporator coils. You can't see these coils without removing a panel on the inside of your freezer. A sure sign that there is a build-up is the presence of any frost or ice build-up on the inside walls, floor, or ceiling of the freezer. Such a frost build-up usually indicates a problem in the self-defrosting system or damaged door gaskets.

The refrigerator is supposed to self-defrost approximately four times in every 24 hour period. If one of the components in the self-defrosting system fails, the refrigerator continues to try to cool. Eventually, though, so much frost builds up on the evaporator coils that the circulating fan can't draw air over the coils. There may still be a small amount of cooling because the coils are icy, but with no air flow over the coils, cooling in the refrigerator compartment is quite limited.

Here's an inexpensive, though inconvenient, way to determine if the problem is with the self-defrosting system. Remove all of the perishable food from the refrigerator and freezer, turn the thermostat in the refrigerator to Off, and leave the doors open for 24 to 48 hours. (Be sure to have several towels ready in case the melting frost and ice causes the drip pan to overflow). This allows the refrigerator to defrost "manually." When the frost and ice build-up has completely melted away, turn the thermostat back to a normal setting. If the refrigerator then cools properly, it indicates a problem with one of three components in the self-defrosting system:

  • The defrost timer


  • The defrost thermostat (also called the bi-metal switch)


  • The defrost heater


If it still does not cool properly, there may be a problem with the refrigerant level or the compressor. You may need to consult with a qualified appliance repair technician to further diagnose the problem

Condenser Self-defrosting refrigerators all have a set of coils and a cooling fan, usually under the refrigerator, that need to be cleaned regularly. If these coils get coated with dust, dirt or lint, the refrigerator may not cool properly. The coils may appear to be a thin, black, wide radiator-like device behind the lower kick-panel. To clean them, disconnect the refrigerator from the power source, use a refrigerator condenser brush (see the Appliance Accessories section) and your vacuum cleaner to clean the coils of any lint, pet hair, etc. You may not be able to get to all of the condenser from the front, it may be necessary to clean the remainder of the condenser from the rear of the refrigerator.
Goodluck..

Why won't my compressor come on but the fan works like it should?


Have service tech check the winding on the compressor, c to r should be .5 ohm or less c to s should be .8 or less and r to s should equal cr + cs. if this checks good you can use a start assist capacitor like a spp4 or spp6

Freezer is not working. was purchased less than a year ago


The entire refrigerator is still under warranty. I would call an authorized repairman.

If you still want to do some troubleshooting: Normal 0 MicrosoftInternetExplorer4 st1\:*{behavior:url(#ieooui) } /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} . Cut everything off for a few minutes then turn it back on and listen for a click from the compressor relay as the compressor tries to start.
Is the compressor motor running.If no check starter/overload relay.
Check to see if the condenser fan at the back underneath near the compressor is running. If no check fan.

Are the condenser coils near there warm or room temp. should be warm

Is the evaporator fan in the freezer running. It blows cold air into the fridge side through a damper in the wall between the freezer and fridge. Make sure the damper is open.

Below the evaporator fan is the evaporator coils. Remove the back cover in the freezer to observe the frost pattern. Light frost everywhere(NORMAL) or a partial pattern of ice(LOW ON FREON) or nothing(LOW FREON OR COMPRESSOR PROBLEM).

I HAVE A PROBLEM WITH COMPRESSOR NOT KICKING ON


Actually you should check also the thermostat control, if you know how to ypass the thermostat control then do it just to check if your compressor running smoothly, well it should be since it was newly replaced,

well if runs, then your problem is your thermostat, but if not then check your supply current if it is stable or under voltage, if it is fluctuating then better yet put a UPS (un interupted power supply) or AVR (auto voltage regulator for your sensitive appliances cause it might also affect other appliances.

If your electric current is stable, then check the controls of your refrigerator, if it is electronic then try to test it with the service center but if it is manual then try to put starting capacitor for your compressor, it might be hard starting,

hope this will help

Check the compressor to see if it is running. Is it too hot to touch. If so make sure the condensor has proper air circulation to cool it. If the compressor is cool to touch and running. There is a leak in the refrigerant sealed system.The compressor isn`t doing any work because there isn`t any refrigerant in it, therefore will not creat much heat. A humming and clicking sound is typical of an overheated or damaged compressor. If the compressor isn`t running and connot start. It could be a bad start relay on the side of the compressor or a bad compressor. If you can remove the start relay, shake it and listen for a rattle sound. If it rattles, it is bad.If not. then it is time consider the cost of a repairman verses the value of the appliance. Check the cost of repair to the sealed system or maybe even replacing the compressor.I hope I have been of some help to you.
