Question about Refrigerators

2 Answers

My refridgerator is not cooling; the freezer is not cooling. It is making no unusual sounds. The water dispenser on the door is not dispensing water. I did already vacuum underneath the fridge earlier, but this seems to have no impact on the cooling or lack thereof. It is the Kitchenaid Superba. Any ideas..

FREEZER /FRIDGE NOT COOLING: Optimum refrigerator temperature at or below40° F(4° C). The freezer temperature should be0° F(-18° C). Check temperatures periodically. Appliance thermometers are the best way of knowing these

Check ur cold control thermostat, ur thermistors in both fridge and freezer ( they should be checked for both ohms and for amount of current being put out as per ur model ), ur air flow vent from freezer to fridge.( to make sure it opens and closes without any restrictions) On thermistors check for A close circuit and amount of ohms not just an Ohm reading. As per ur model. Most should atleast show 1200 ohms. Also Check door seals for leakage.
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.
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.

FAN check to see if it is operating or restricted A fan that is not blowing or restricted will not circulate the cold air properly.

Often, the first thing that folks do when their refrigerator starts to feel warm is turn both controls on the coldest settings.This is exactly the WRONG thing to do.Turning the cold control to the coldest settingwillkeep the compressor running longer and make lots of cold air.

But turning the air door to the coldest settingclosesthe airway to the food section. Lots of cold air is made, but most of it stays in the freezer section, and the food section actually getswarmer.


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 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.
May also need to check the defrost timer, u can get by and test manually by placing a small screw driver into the tiny slot or hole underneath the timer and turn slowly clockwise till u hear 1 click. this will engage ur defrost cycle in about 15 minutes u should be able to come back and feel the heat in freezer as it melts the ice providing ur terminator is not bad?
Another way to test it is with a multi meter. Remove timer it from fridge and you will see 4 prongs numbered 2,1,4,3 in that order. Place ur meter prong on prong 1 & 3 (if your fridge has a capacitor wired in series with the windings, then u check for micro fares rather than OHMS) If u cannot confirm this test, still try the next.
Take ur meter prong and connect to prong 1 & 4, it should read resistance or ohms ( closed) now remove prongs and place on prong 1 & 2, this should now read infinity or open (no ohms) now take a small screwdriver place it in the tiny hole or slot under the timer. Turn it clockwise slowly till u hear 1 click. Now ur 1& 2 should read closed ( showing ohms or resistance) now place meter prongs on 1 & 4 and you it should now show open ( or no resistance - no ohms) this is how u know ur timer is good, Remember when testing for ohms ADJUST meter to use a high ohms rating in the thousands as the resistance is very high in OHMS. And adjusting to low ohms rating may give a false reading or not show the proper resistance..

THE COMPRESSOR:
If you hear a clicking sound coming from the back of your refrigerator/freezer, then the problem is most likely the compressor, relay and or capacitor is overheating or not getting proper power and will not start.The compressor is the component on your refrigerator that allows your refrigerator to cool. If this component is not working properly your refrigerator will stop cooling. Most of the time the compressor is not the component that has failed.

To check ur compressor with multi meter:
Disconnect and remove the relay and capacitor from compressor, somes located next to compressor in a casing.

You wills see 3 prongs coming out of compressor. 1 goes to ur srtart winding, 1 goes to ur run winding and the center goes to ur ground.

Place ur meter connector or prong on the start prong and the other on the ground (center prong) take note of the reading in OHMS for example 5 ohms.
Next place meter prong on run prong and the center ground prong agin. Take note of the reading in OHMS. Example 4 ohms

Next place meter prong on the start prong and the other on the run prong, now take note of the reading example 9 ohms. Now match the total of this ohms test with the total of ur two separate test. 9 ohms, if they match ur ok give or take 5 percent plus or minus. One more test to make to test of there is a short in compressor attach meter prong to ground prong and rub the other end of meter prong to metal ( scrape the metal clean of paint and test on metal surface not painted surface. If it shows continuity or ohms , u have a short in ur compressor. It should show infinity

Lastly you should also check ur THERMISTORS in the freezer and fridge section for continuity OHMS and for amount of OHMS current being put out. In most models around 13000 ( give or take 150 ohms) ohms is required.

That you have two very different problems is interesting :) could it be that you had a water leak inside that has completely frozen over your evaporator unit. Not knowing you model, but in general inside your freezer you can remove the back panel and see the evap coil... if it is frozen solid, it will not effectively cool. This can happen over time if the defrost isn't working right, but that you don't have water... maybe it leaked and froze it over.

Hopefully they are seperate and the water dispenser is just a bad switch or valve.

I have a side by side refridgerator freezer. I have just connected the water to the ice make / water dispenser for the first time and just a short trickle of water flows into the ice cube maker - not


I would guess that you need to purge the air out of the lines and system for it to work correctly. You can hold down the water dispenser for awhile to help, but if you do nothing, it should purge itself over the next few days.

GE gsl25jfpabs Profile. Water stopped coming out of dispenser. Frozen? New valve? Help


Yes, probably frozen. Open the door, minimize the freezer setting in the refridgerator section, and try out the dispenser every once in a while until you get water to flow. Might take a couple of hours so make sure you have a backup freezer or a big cooler for your food.

We have an Electrolux Wave Touch with the same problem.

Disconnect waterline at bottom of freezer door and activate solenoid - then you know for sure.

1 year old Kenmore Elite Trio Refridgerator not cooling


There are a lot of things that could be the source of the problem... is there no cooling at all going on in the freezer? Is the back wall of the freezer cold? It could be anything from a fan, to the compressor, to the control board... you need a technician.

I would get on the phone with Sears, and explain the continuing problems you have been having, and they may agree to cover service.

AMANA refridgerator water dispenser not working. Freezer door not closed properly last night.


Hello schlucks
welcome to fixya.

You said, Your AMANA refridgerator water dispenser not working. Freezer door not closed properly last night.

When the door to the freezer was left open all night,the moisture from outside caused the water line to the water dispenser to freeze!
What you need to do is to move all the articles from your freezer to a spare or second freezer
temporarily.
Then turn off the freezer compartment of the first unit where the water is not depensing .
you will need 12 to 24 hours untill the line defrosts.
If the dispenser works sooner then don't wait any longer to restart the freezer.

In some models, the fact that the freezer is turned off may affect the power in the dispenser untill the freezer is turned back on.

After you finish defrosting and turn the freezer back on. give it 24 hours to get back to running temperture.
Then reload the articles agin.
BUT DO NOT TAKE 20 TRIPS TO BRING THE PACK AGES AND LOAD IT, LEAVING THE DOOR OPEN AGAIN!
Bring the articles to the freezer and load it straight awy quickly and close the door.
This will solve your problembarring any damage to the dispenser!t
Thank You for having me advice you.
Huuum
Please remember to leave a rating!
I'm sure you are solved!



Some info!!!!!!!!!!

cold air to the bin and make it colder.
Water and Ice Dispensers
(on some models)
Depending on your model, you may have one or more of the
following options: the ability to select either crushed or cubed
ice, a special light that turns on when you use the dispenser, or a
lock option to avoid unintentional dispensing.
NOTES:
■ The dispensing system will not operate when the freezer door
is open.
■ After connecting the refrigerator to a water source, flush the
water system. Use a sturdy container to depress and hold the
water dispenser lever for 5 seconds, then release it for
5 seconds. Repeat until water begins to flow. Once water
begins to flow, continue depressing and releasing the
dispenser lever (5 seconds on, 5 seconds off) for an
additional 2 minutes. This will flush air from the filter and
water dispensing system. Additional flushing may be required
in some households. As air is cleared from the system, water
may spurt out of the dispenser.
■ Allow 24 hours for the refrigerator to cool down and chill
water.
■ Allow 24 hours to produce the first batch of ice. Discard the
first three batches of ice produced.
