Question about Refrigerators

4 Answers

Hello: Freezer works well. 0 temp. and makes ice. no frost in freezer or coils (checked). Refrig.section temp. reading does not correspond with the 3 guages placed in the refrig. Set temp.at 33 deg. and the dig.read-out will say 37 and my guages (3) say 45 or 46 deg. The damper door will open on command. Is there a temp. reset procedure or a bad thermistor? Schematic shows a thermistor but cannot find. Is this a mother board problem? Refrig. 5yrs old and have had problems from day 7. The lowest temp. reading is 38 F. Thanks JC

    The refrig.digital temp. reading is indicating a temp.of 25 deg. and actual reading is 40 deg.All fans work, no frosting on coils in freezer (inside panel removed to check for frost). No dust on cooling coils-compressor fan works. Evaporator pan has defrost water in it at different times. Where is the THERMISTOR located for telling the refrig.controls what the temp. is inside the refrig.section so it can open the damper and allow cold air to flow-in. If I remove the damper the refrig. department will go down to freezing and lower. There must be codes to reset temperature settings or a bad sensor. Thanks J.Cooney

    Hello:

    I have set the temperature at 37 deg.as recommended by Frigidaire. The refrig. sensor at the read-out says the refrig. temp is 27 deg. and obviously the damper door (which is working) will not open to allow cold air to enter. Because my food is not frozen does not mean the sensor is not working in the opposite direction that you stated. If the temp.sensor in the refrig. is sending a false reading to the central controls then the refrig. will be either too cold or too warm. Please tell me where the THERMISTOR is located-there are two-one in the freezer and one other. Please tell me if there are code settings for the thermostat. I have been playing with these buttons and have changed the read-out since going on line with you. I have just cut power to the refrig. to see if there is a "default" setting. Thanks, J.C.

    Good Morning:

    Freezer always at 0 deg. no frost anywhere. Freezer fan works, damper door works, compressor fan works, coils are clean, defrost water in evaporative pan at reg.intervals. When I take the damper door COVER off, the temp. in the refrig. will drop to 33 degree with the thermostat setting at 48. This COVER is styrofoam insulated and affects the sensor for refig.temp. The same thing happens when I remove the damper all together. I have come to the conclusion that I will call-in a service repair Tech and you can have my $9.99. Thanks, J.Cooney

Im sorry your experience with FixYa hasn't met your expectations.
You should be aware that all "Experts" on FixYa are not experts.
Before leaving - I will attempt to answer your questions.

Your original posting is indicative of a failed thermostat, damper controller, or controller board.
.
However - neither in that, nor subsequent, posts do you state the model #.

Without a model # I cannot determine which of (or if) these devices are installed.

I realize it is a Frigidaire - however there are MANY styles.... and a model # is necessary to determine part replacements and locations.

If you would like additional help - please use the "Continue with this Expert" option and post your model #, and if your skillset allows - we can get your fridge back up and running normally.

If you wish to have a live tech repair - so be it.

Thanks for using FixYa!!

Are u saying the lowest temp you can get the fridge is 38 F? if so the thermistor would not be the problem.

Normally a good cleaning of the condenser coils would have solved this one as well as fixing the seals of the door.  The temperature outside the freezer is determined by how much cold air from the freezer is being circulated.  THere could not be enough cold air coming outside to match the temperature you have set.  Have the freon checked if it is still Ok.
Defective thermostats would normally cause your fluids stored in your fridge to be partly frozen.  To be sure you may can test it by opening it up and using a continuity tester probe.

Hi,

Check the back wall or floor of the freezer section for frost. Check the freezer( evaporator) fan to see if it is running. Check the condenser coils( under the unit ) for blockage from dust. Check the condenser fan (under the unit) to see if it is running.

If you have frost in the freezer there is a problem with the defrost system and the freezer will start to warm eventually as well as the fresh food section. If that is the problem you can check the defrost terminator, defrost heater/s, and the defrost timer or adaptive defrost control If used on your unit or the main control board if so equipped. These things usually require dismantling the freezer and other areas of the refrigerator to be checked.

You could defrost the freezer by disconnecting the power to the refrigerator and letting it sit for at least 24 hours with BOTH DOORS WIDE OPEN to allow the frost to melt completely but it will build up again in 1-2 weeks and start the warming up again.
What is the outdoor temperature?

In warmer climes, it may be necessary to blow a small fan across the cooling coils in the rear of the fridge to allow for better cooling. This is accomplished by opening the refrigerator access panel on the outside of the AS and either using a small battery operated fan or a 12 volt one that you can wire into a 12 volt power source in that compartment. We use a 3 inch computer fan from radio-shack - about $10. The compartment is designed to create a chimney effect, but in warmer weather a boost helps a lot.

In the fridge itself, we also use a small silent fan made for RV fridges to provide even distribution of cold air. They run on 2 D cell batteries which last a whole season.

Finally, a bag of ice in one of the fridge drawers will aid in faster cool-down and also in keeping the fridge cold.

Thanks for contacting Fixya

Fridge is slightly cool but will not get cold, even on top setting. Tried cleaning it underneath and fixed for about a week and then it broke again.


NOTE: This
is a multi-solution answer since I don't have all the tech from your question to pinpoint your problem
But the solution is in here generically, if you read and study the solutions very,very carefully.
First I would check cold control. Thats where you turn it off, if your temp is not warm. it can
be defective and not shutting off. If your temp is warm proceed with the following.
I would check the fan in the freezer. Listen to see if it is running
It moves air to the ref from the freezer
Then check to see if FREEZER CONTROL is turned WARMER WHICH MAKES THE REF COLDER AND VICE-VERSA. SEE?
The ref. temp should be about 33-35
The Freezer temp should be 0 to 10 Any thing below these temps is overkill and a waste of elect
The higher the number you turn it up to is the coldest
But is probably a common defrost problem The ice build up
is not being melted by the defrost system.The fan can't blow through the coils into the fridge.
Take out back panel of freezer to check for ice buildup. The coils should be clean.
There are three components to a defrost system- a heater,heater thermostat, and a timer unless you have a defrost electronic card.
Its best handled by a Technician but you could possibly do it by taking your model number to the nearest appliance parts store and asking for the parts. They are mostly located in freezer ,behind back panel on freezer coils.except the card which is usually located in ref The parts store will have info
Also check fan undernearh Ref in the rear
Clean condenser coils underneath
Make sure back cover is on the fridge. Some take them off and throw them away.
make one out of cardboard if its gone, using the holes of the old one.

Hi,

All the cooling coils for this model are in the freezer section. There is a fan down there behind the back wall on the top. This fan directs air up to the fresh food section.

Check the temperature of the freezer you can do this by inspecting the ice cream, if the ice cream is soft you are above 5 degrees F. If you have a good cold freezer then the problem is with air flow, the evaporator fan that I spoke of could be bad).

If your freezer temperature is not as cold as it should be you may have a defrost problem, look for any signs of frost build up on the back wall of the freezer section, if you see frost you will most likely need to put in a new control.

If the freezer temperature is warmer than normal and you do not have frost you may have a sealed system leak, this will require a technician for sure.

Frigidaire top-mount refig. freezer won't get cold ,temp.stays around 26 degrees, refrig. don't keep milk cold enough


check that the evaporator fan motor ,located in freezer is working.it circulates the cold air.also check that the coils behind freezer back panel are not iced up,this would indicate a lack of defroting due to,timer,heating element,or bi-metal.lastly when the refrig is running those coils should get frost over them all,if not you may be low on refigerant

Make sure it's opening and closing when you adjust the fridge temp.
The problem could be the electronic control if you have one or the mechanical linkages.



The ideal temp for the freezer is around 10 degrees F.
Look at the evaporator coils behind the rear cover inside the freezer and check the ice forming on the coils.

Freezer compartment has frost buildup


This can be caused by the drain hole below freezer coil being blocked by ice. You MUST remove all ice in drain under freezer coil. Use turkey baster to squirt hot water into hole and use hairdryer to defrost. Possible defrost thermostat is defective. Unit never goes into defrost, ice forms on coil and in floor of freezer. After defrosting may work OK for a week or two but gradually gets warmer because ice is blocking ports where cool air gets to refrig. May also have water in refrig box. Can also be caused by defective defrost timer.

ED25PQDW01 side by side refrig -freezer is inconsistent. Need to have full cold to maintain freezer temp. cleaned coils, but still an issue.


Do you see a light coat of frost in freezer section about 12 inches up (defrost problem indication) ? Has the icemaker slowed down a bit in ice production ? What is the refrigerator control set on ? When you turn the freezer up completely , it cuts off the cold air flow which cools the refrig section . If refrig control is set mid way , turn it up higher , so refrig will run longer , but lower the freezer setting so some cold air will enter the refrig section . Also check to see if the freezer fan is working .

Confused /


Ok the freezer section works the refrig section think of the refrigerator as a large cooler with an inlet and outlet hole cold air is blown into the refrig from the freezer via the fan motor in the freezer the really cold air comes in the top of the refrig and drops to the bottom of the refrig then it is sucked back into the freezer thru a vent hole in the bottom of the refrigerator ..GOT IT?? Now when a unit has a defrost problem there is an ice or frost build up in the freezer on the coil (bad heater,bad bi metal, bad timer can cause this) the ice builds and builds to the point where it blocks the air flow across the coil hence the air can not get to the refrigerator section making it warmer but the freezer section will work ok .. I hope this makes sense...Hint : A sign of this is a lg frost buildup on the back wall of the freezer.
