SOURCE: evaporator coil iceing

if you can put the frig. in defrost this will tell the sensor to turn on and you will see the heater melting the ice,if you can't put it in defrost and the sensor still has ice on it,simply put it in your hand,as your hand warms up you should feel the sensor pop,this pop tells the heater to turn off,if no pop the sensor is bad,if no ice on the sensor put it in a glass of ice,chill it down and do the same hand test,you can also use an omhs meter to check it,all the sensor does is open and close,let me know what you find-mike

SOURCE: heater works defroster does not

It sounds as though you're having problems with your controls...if it were the ducts...you'd get some kind of a air current..even a faint one

hope this helps

SOURCE: evaporator coil freezing, replaced main control

It is possible you have a defective fan motor in the condenser area or evaporator area. Sometimes when they become defective they will run for a while and just warm up and stop while the compressor continues to run. I learned that one on four costly returns to the home. The cost was to me not the customer. Thanks, Sea Breeze

My Haier model HBF05EBSS-01 will not cool below 50 degrees F.


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.

Why isn't our refrigerator staying cold? It is staying around 50 degrees and no lower.


How to check everything
http://www.acmehowto.com/howto/appliance/refrigerator/refrigerator.php


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.

No Cooling in the Fridge section, freezer is icing


Generally on these models they rely on cold air being pumped fr\om the freezer to the fridge and have a adjusting device to control the flow, you need to locate and check this is free and working properly. Another reason for freezer ice up is a shortage of gas in the unit, this is usually unfixable as the leak can rarely be found as it usually occurs within the cabinet case. Sorry to say it would then be a throw away.
