If these coils are clean and the fans are operating then the refrigerant charge needs checked. I would also check the compression ratio on the compressor to see if the compressor has weak reed valves. this would let the refrigerant pressures equalize. and would not remove heat as efficiently as it should. This would make the compressor run alot more

Hi,Ihave had my electrolux fridge freezer for two years now and it is sited in my garage.When it gets really cold the freezer turns off defrosting everything,just found out if it drops below 10 degrees it...


Good day,
Not really. Domestic refrigerators are designed to operate in an environment where people live.
Most all manufacturers recommend that they not be placed in an area that goes below 55 degrees.
At any temperature below that it starts to degrade.
Cold enough and it will not work at all.
The reason is once the fresh food compartment reaches it's normal temperature of 33-37 degrees, it shuts the whole machine off.
That is by design, on any refrigerator like yours that has only one compressor and cooling fan motor.

As well, there are other issues. In that situation, the machine could well stay off 12 to even 24 hours.
The compressor has an oil sump in it, and the oil becomes very thick. When it finally tries to start, it creates a very stressful situation for the compressor, and could substantialy reduce it's life.

My Artic air makes a grumbling sound, it sounds like the compressor may be cycleing, the outside walss of the frezzer are very wam to the touch but inside temp varies from 20-40 degrees. The door seal is...


Check to see if the condenser fan at the back underneath near the compressor is running. If no check fan.

OR


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 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.

If you need help finding your model number see here> http://www.appliancepartspros.com/modelnumber_locator.aspx

To locate your timer, motherboard, control or adaptive defrost control , enter your model number and search for the part or post back on Fixya.

Freezer is getting to about o degrees but refrigerator section wont go below 50 this is amana side by side asb2623hrw also changed the defrost timer about a month ago and blew off the coils from underneath...


Check your lower air shutter that lets cold air move from the freezer to the refrigerator's. You may have something blocking the air flow, food, plastic, etc... There should be a dial that opens, and closes the door.

Freezer won't get below 13 degrees


Make sure the evaporator coils behind the rear cover inside the freezer are not iced up too much. This would indicate a defrost problem and will get worse.
If the compressor is still cycling off and on the cold control could be at fault.

BEKO Frost free freezer not as cold as it should be!


Sorry I don't have a solution for you, however would like to know if you found out what was wrong. I have an identical problem with my Beko fridge/freezer. It's only 14 months old and the freezer just wont freeze. I've turn it off for 24 hour and let it defrost completely (even had the panel off to make sure there was no ice left). I've turned it back on again and it still wont freeze. Everything seems ok, ie fan blowing, motor running etc. I really am beginning to regret buying Beko. thanks

Freezer Thawing Out


This will not cause a freon leak and it is possible that the door was left open, but to be certain that you don't have a defrost issue, follow the guide below to diagnose any problems. Also the warm walls are normal during compressor run times.
Below is a link that will help you with parts and diagnostic procedures that are specifically tuned to your manufacturers data plate information.
http://www.repairclinic.com/0047_3.asp
If your freezer cools but doesn't get cold enough, it may have a problem in one of several areas. To better understand the proper operation of a freezer, read about freezers in the How Things Work section of our website.

In a self-defrosting freezer, poor cooling often results from a heavy frost build-up on the evaporator coils. You can't see these coils without removing a panel inside your freezer. But if you see any frost or ice build-up on the inside walls, ceiling, or floor of your freezer, it's a sure sign of frost build-up. And that's a sign of a problem with the self-defrosting system.

Freezers should self-defrost three to four times in 24 hours. But if a component in the self-defrosting system fails, the freezer continues to try to cool, instead. Eventually, so much frost builds up on the evaporator coils that the circulating fan can't draw air over the coils. There's still some cooling because the coils are frozen. But with no air flow over the coils, the cooling is quite limited and the freezer isn't as cold as it needs to be.

An easy (though often inconvenient) test of whether the problem is with the self-defrosting system is to remove all of the perishable food from the freezer, turn the thermostat to Off, and leave the door open for 24 to 48 hours. (Keep several towels handy in case the melting frost and ice overflows the drip pan). This "manually" defrosts the freezer. When the frost and ice build-up has completely melted away, turn the thermostat back to a normal setting. If the freezer then cools properly, it indicates a problem with one of these components in the self-defrosting system:

  • The defrost timer. To test this, manually advance to the defrost cycle. The unit should advance itself out of the defrost cycle in about 45 minutes.

  • The defrost thermostat (or bi-metal switch). This thermostat allows current to pass through it at temperatures of 20 to 30 degrees Fahrenheit and prevents current from passing through it at 40 to 60 degrees (depending on its design). This is difficult to test, though, because it takes a prolonged, very-cold temperature to turn it on.

  • The defrost heater. You can test this for continuity using an electrical meter.

Kenmore 23.1 cf Chest Freezer not cooling below 14F


Make sure everything is working, I.E. compressor, fans. Now I need to know if the freezer shuts off at 14 degrees, or does it continue to run without making temp. If it shuts off, then the first place to look is the thermostat. It may be out of calibration. If it continues to run, then the solution may be as simple as cleaning the condenser coil. or the defrost has malfunctioned somehow. Defrost probleams will cause excess ice on the inside coil. You may need to remove the panels to see how much ice is on it. It sounds like the compressor is good, as it is pretty cold. Just not cold enough. A deep freeze should be at least 0.
