Question about Refrigerators

How can I set the freezer's control knob?

I do not think that the coil is frozen as I have just defrosted the fridge and freezer. It is subsequent to this that the freezer is not freezing things. It did freeze a tray of ice blocks and they have not defrosted, yet anything else has just been kept cold and not frozen. I have set the control knob with the number 3 opposite a molding on the side of the fridge.

FREEZER /FRIDGE NOT COOLING:
Check ur cold control thermostat, ur thermistors, 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.
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

Freezer not freezing


Kenmore brand refrigerators offer energy efficiency and space saving benefits with a range of innovative designs. The company's refrigerator-freezer units are manufactured in traditional top-mount freezers, bottom-mounts, and side-by-side styles. Occasionally, as with any brand of appliance, the components can malfunction and cause the freezer to stop working properly. A few troubleshooting steps can help locate the problem so that it can be repaired.

  1. Power Supply
    • Occasionally the power cord to your fridge slips out, or the outlet it's connected to is defective. Before troubleshooting other potential problems, check that your fridge is plugged in, and if it is, try plugging something else into the outlet to confirm that it is working. If there is no power, check the fuse or circuit breaker and replace or reset if necessary.
    Thermostat and Compressor
    • Freezers rely on the thermostat to know when to turn on the compressor and when to turn it off. Thus, the thermostat controls the temperature in your fridge. Typically, for a Kenmore refrigerator, the recommended setting for both the refrigerator and the freezer is 3. Check that both are set properly and if they are, try setting the freezer's thermostat to a slightly colder setting. The refrigerator's compressor should turn on. If you don't hear a fan turning inside, your thermostat or compressor may need to be replaced.
    Defrost Timer
    • The defrost timer regulates when the freezer and fridge will run its defrost cycle. If your fridge is not defrosting, or it is defrosting too often, this can affect its ability to freeze food. When in defrost mode, the freezer stops blowing cold air. Test the defrost timer by manually advancing the timer using a screwdriver inserted into the advancement pinion. Turn it clockwise for a 1/4 turn. This should force the timer to advance out of defrost in less than an hour. If it does not, you may have to replace the timer.
    Evaporator Coils
    • When the evaporator coils become frozen, your freezer will likely malfunction. If they are dirty or dusty, the same problem can occur. To defrost the coils inside, you can turn your freezer off for 24 to 48 hours then turn it back on. If it works properly, then the evaporator coils were frozen. Clean the coils located on the back of your fridge as well to ensure that dust and debris aren't affecting their efficiency.
    Wiring
    • The wiring outside and inside your fridge can be damaged by rodents or pets. Check the wiring outside your fridge for breaks. If there are none, you'll have to check all of the wiring. This is a long process requiring you to use a meter to test each connection. You may want to call an electrician to test the wiring to ensure that it is done properly.
    Environmental Factors
    • Once you've checked each component that runs your freezer and confirmed they are working correctly, consider that factors outside the freezer can affect its ability to freeze properly. The problem may be that the door is opened too often or for too long, allowing the cold air to escape and raising the temperature inside. Check the seal around your freezer door to ensure that it is getting a tight seal when closed and no gaps are allowing warm air inside. If you've added a significant amount of food all at once, this will increase the temperature inside and freezing can take several hours. If the vents are blocked by food items the movement of cold air is limited and will affect the freezer's temperature as well.

Hope this would help you.
Have a nice day! : )

Hi Rob,

The problem in your case is most probably with the defrost thermostat.

It can be found on the evaporator i.e. freezing coils , it's round disc like with two wires.

If you get this replaced with a new proper working unit ,

Also make sure you replace the defrost timer as well if the problem persists.
Hope this helps ..:)

DEFROST PROBLEM
The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.

If this ice is not melted it will continue to build up until the air can't flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.

If the defrost thermostat is bad, it can prevent the heater from coming on OR it won't turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass(disconnect the two wires plugged into it and twist them together) the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.

The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it's bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it's in the defrost mode.

If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls in some models and on the back in others.

FREEZER WORKING BUT FRIDGE NOT


Remove the rear panel in the freezer and see if the evaporator coils are frozen over.
If so dethaw coils with a hair dryer.
Reassemble freezer and set controls to the normal position.

Although you replaced the defrost timer if the coils were frozen over in the freezer no air can transfer to the ref. section from the freezer.

If you do not want to dethaw the coils unplug the ref. for 1-2 days and leave the doors open .The coils will dethaw by then.

Maytag P MFD2561HEB model the frig is not cold but the freezer is fine. How do we set the frig control?


The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp.


If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

Bosch Fridge Freezer: Fridge Not Cooling


Your refrigerator's cool is provided by your freezer section through a damper - there should not be excessive frost on the cooling coils - the most common problem is a defrost timer - are you absolutely sure the noise you hear is the defrost this is the first thing to check, defrost control and its components, is it properly shutting off or stuck on during operation - the next thing to check is for possible sealed system problems / small leaks, door gasket seals, etc.

The fact that it started to work once you manually defrosted is the key here - an over forsted evap will cause the problems you describe most commonly - so have your defrost system checked completly and properly - that should solve the problem. followed by checking door gaskets, damper and sealed system - if only part of the coils are frosted as opposed to the entire surface, that usually a clue to sealed system leak - yes 10C is quite warm for a refrigerator. It should be between 34F-40F, optimal is 34F. And freezer section no warmer than 10F, optimal at 0F (-18C)
