If its again building up ice, that means the unit is not defrosting.Its starting the cooling procedure, then while defrosting, its not working.The defrost assembly consists of three main parts.The defrost thermostat, the defrost heater and defrost board.Any of the one is not functioning.When thermostat sense the maximum cooling, it triggers the defrost heater to start heating and this defrosts the ice collected on the coils and the system works.Both thermostat and heater are controlled by defrost board.First the thermostat and defrost heater to be checked, if both check ok by meter and visually, then its defrost board causing the problem.You can get required parts from from online sites
like:---www.repairclinic.com or from searspartsdirect online site.-----------
Before that you can try manual defrost reset procedure.The manual defrost reset
procedure is as follows : ----First unplug the unit from main power outlet. Then empty whole unit completely.
Then keep both the doors open. Wait for 24 hours. All the ice collected on the
coils and in the freezer section will get melted. Clean the water
from the sections. Then Connect the power cord of the unit to main power outlet
after 24 hours/.Then set the temperature to normal in both fridge and freezer section.
It will take near to 4 hours to get run in its proper cooling cycle. Then check,
if the problem returns again. If the same problem occurs then it's defrost problem. ------------------ This should help.Thanks.Helpmech.
Ice building up in the freezer is not good, it means that your defrost heater is not working.The purpose of the defrost heater, as the name implies, is to prevent ice from building up on the evaporator that is inside the freezer compartment. The heater and/or thermostat failure is responsible for the ice building up in the freezer. Replacing both of is recommended, but if the heater shows continuity with an ohmmeter, just replace the thermostat; if in doubt, replace both of them and your refrigerator should be back to normal. Do not forget to clean the refrigerator condenser fins.
usually this is a defrost problem...See if there is ice building up on freezer back wall and if so, you will find the evaporator froze over. I would first make sure you see or hear the freezer fan motor coming on. A evap fan not coming on will cause a no cool problem in fresh food section.
If there is ice on the freezer coil. It needs to be defrosted and then we can find the problem. Once its defrosted..it will work good as new until it freezes over again..The most likely problem is defrost thermostat or heater or timer or electric defrost board...you need to know how to use a meter to check these. The defrost thermostat can be bypassed to check it. use your meter to check the heater..if good, and you bypassed the thermostat and nothing happened..Its most likely the defrost timer or board. If a manual timer..you can advance it to defrost and see if it comes on.
if its an electronic defrost board, sometimes you can get them into a defrost by pushing the light switch in 5 times within 10 seconds..there may be a tech sheet on the refrigerator showing this
please let me know if you need more help....Bruce
This appears to be a defrost problem. Either the defrost heater is burned out or the defrost thermostat is defective. Look into the rear wall of freezer for a layer of frost building up that will tell you that there more than likely is a large area of snow and frost building up on the evaporator coil. Once you manually defrost the coils you will be able to see the part number WR51X10038 Defrost Heater. It has a glass tube on the outside so it will be easy to spot if the defrost heater element inside is burned out. If you change the defrost heater I recommend that you replace the defrost thermostat part number WR50X10054 Defrost Thermostat. The defrost controls on your model come from the mother board so the is no defrost timer or adaptive defrost. The mother board make the decision when to defrost. When you are able to unplug and inspect the evaporator coils in back of freezer back wall panel let me know what you find, Thanks Sea Breeze
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.
Your defrost system must be on the blink. The defrost system is used to keep slabs of ice from forming and disrupting flow of air to that fresh food compartment. In the old days grandma would just unplug the unit every 2 weeks and place a chair in front of the the ice box, holding the door open for an afternoon to kill the frost buildup. Then came the modern frost free icebox. Every 8 hours the timer would kill the compressor and kick in a heater to melt that old frost. A bi-metal thermostat was installed in line with the heater to shut it down at 50 degreesF, then the ice box would just keep quite and set a spell (21 mins) then like magic the ice box would roar back to life, get cold, and chill out. That is until you opened the ice box door and violated grannys 3 second rule and caused the compressor to come roaring on and scare the cat half to death. Nowadays instead of timers(we don't need no stinking $2 timers) we built in computer boards with fancy sensors to monitor capacitance changes in the evaporator coils and issue orders from main computer board to defrost board to commence defrost cycle all the time monitoring for any changes in our daily habits, taking in consideration of how many times we peek into the ice box and look at grandmas strawberry shortcake. Keeping up with each and every ice cube we consume and checking the temperature and quality of our water and ice in the door. OH my! So what could go wrong? Well barring hurricanes, tornatoes, thunderstorms, earthquakes, and other natural disasters, all ice boxs still need a heater and a thermostat. I would start there. Of course if you had have specified a particular model number and brand so that a date age and a few components could have been looked at then I could have posibly given a more specific answer. MORE
We had the same problem with our GE frig, a Profile 24. When the tech came out, he explained that the energy efficient models have only 1 defrost heater, but the older units had 2 and the hook up and mounting positions were still there. As long as I directed him to install the 2nd heater he could do it. It turned out the original heater was just fine, so the replacement was installed in the 2nd heater space and it has worked fine for several years now. Before doing this on yours, I would verify that the defrost timer is working and the heater unit is ok.
