SOURCE: Defrost Heater or Main Control Board, Which one is at fault?

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} To answer your question I know of no reason the electronic type of board would cause the heater to go out unless the defrost thermostat (or sensor) and board stuck in the defrost possession and did not stop the heater. Any time you replace the board and have had a defrost problem a check of the heater will either confirm or eliminate it but the defrost sensor should be replaced if the board is being blamed for non defrost. I cant rule out 100% that a bad board will not cause a heater problem but the high 99% range is most likely. If you have a volt ohm meter and can find the heater circuit on your board and the freezer has been running down to correct temp you can check the defrost circuit by ohming it out. Lower resistance of 10 to 60 ohms is common. Anything higher will require ohming the heater out directly and the defrost thermostat will be open if the temperature is above the stats range.

Common to all self defrosting refrigerators / freezers is the need to move air around to pickup heat inside the compartment. Common to all frost free refrigeration to maintain this feature are 3 items:
1 and initiator (defrost timer or circuit board),
2 A heat source for defrost (Usually an electric heat element but can be other types of heat sources)
3 A safety limit to stop the heat source, leaving it warm enough to defrost and keep the heat contained where it will not affect the compartment advisedly. In a standard type defrost (non - electronic) it is called a thermostat. In an electronic board defrost it is called a sensor.

The defrost timer / or board will never be in the Freezer. Other than that it could be in the refrigerator section behind a plastic cover or metal cover on the back outside. It could also be under Neath the front corners or center of the front kick plate.

A timer you can turn the cam clock wise till it clicks. A board will depend on the manufacturer as to how to send into defrost for a test. A sensor on the defrost type board may be required to by-pass into defrost or test mode.

The freezer section has the only cooling coil. It sounds like it is blocked with frost and thus won’t let the air circulate from freezer to refrigerator.

There is a defrost timer, (or board), a defrost heater, and a defrost safety thermostat. Any One of these or a combination of 2 can be your problem. If you have a energy efficient model that has electronic controls then you will have a board. The procedures for checking the circuit on a board vary by manufacturer of the board used and manufacturer of the appliance.

The defrost heater always has resistance and is attached to the freezer coil.
The defrost thermostat is also attached to the heater electrically, unless it is an electronic sensor type. Sensor types have a range of resistance that needs to be known to check and varies slightly with the temperature of the sensor.

If I haven't lost you here you maybe equipped with the life experiences that will allow you to do most of these checks. If its over your understanding I recommend you contact a reliable technician..

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

SOURCE: Defroster isn't working on GE Frig model

Hi,
I'm Leo
First 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
Also this might be a common Defrost problem, Ice
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
If this was helpful please rate me

Ge side by side ref.


no,its more than likely the defrost heater located just under the coil thats freezing up,check this heater for continuity,if its o.k. then test the defrost thermostat thats clipped onto the same coil near the top of the coil,note,the defrost thermostat needs to be below 15 degrees to check good as its a thermal switch,then if still problems then check the main board in the back of the unit behind a panel this is where the defrost circuit gets its power,but i will likely say its the heater thats open because i replace about 5 per week with the same issue as yours

My side by side coils freeze. I already changed out the mother board but within two weeks it freezes again. Any ideas?


You may have changed the wrong part.
The defrost heater and defrost thermostat are bad.
They are located inside the freezer coils behind the freezer panel.

I have a GE side-by-side refrigerator/freezer that's not maintaining cold temperatures. I was told to replace the defrost thermostat which I did and it seemed to work for about a week or so. But now it's...


If the refrigerator isn’t cooling at all the motherboard is a good possibility burnt marks or not. If the fans are not running it could be a defective fan, motherboard or both. Take a look at this page http://www.appliance-repair-it.com/refrigerator-fan-motor.html

If the refrigerator isn’t defrosting properly, after a few days the freezer coils will get blocked out with heavy frost. There are four things that will cause this, defrost thermostat, defrost heater, evaporator thermistor and the motherboard. This page should help http://appliance-repair-it.com/GE-refrigerator-repair.html

Mine freezes up and I too have to use a hair dryer about once


How to check everything
http://www.acmehowto.com/howto/appliance/refrigerator/refrigerator.php
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. Since your heater does come on but not when it needs to I suspect the electronic control.

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

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.

Ice building up in freezer


Due to the frosting up, The glass defrost heater broke. Any good tech knows this happens. The defrost heater must be replaced. If this is a GE side by side. The new replacement heater has dual elements. The standard heater that was put in them, was not large enough to defrost the coils fully. Replace heater and you should be fixed up. I would also replace the thermostat while you are in the freezer section they are only like 15 bucks and this way you will have a new defrost circuit.

GE refrigerator TBX25zpk coils Freezing


It's almost always the defrost heater. If you have volts to the defrost thermostat the defrost control is working. Set your meter to check ohms and remove the wiring from the heater. If anything changes when you touch the meter leads to the heater terminals then the heater is probably good, but my guess is nothing will change, which means you've got a bad heater.

Defrost issues


If it's around 2-3 years old, my first guess would be the heater is bad. The GSS models have problems with the heater almost always about that time.

Test the heater and the defrost thermostat for continuity with a multimeter. Whichever one doesn't get continuity is bad and should be replaced. If they are both good and the evaporator fan is running like it should, it will be the main control board located on the back of the unit.

Let me know if you have any other questions about this issue.
