Frost building up in top of inside of fridge - Refrigerators

Posted by on

  • odesa Jul 21, 2008

    I have a fridge where the freezer is on the bottom. My freezer has no frost build-up. However the top 3 shelves of my fridge have frost on the back of the wall of the unit. The coils are fine. The whole unit cools and freezes well. I just got the unit 4 days ago. It's 5-years-old, but the former owner says this never happened to her, except when the door was opened frequently. (I do not fan the door.) To be transported the unit had to lay horizontally for about 2 hours. However, I waited over 2 hours after it had been set in an upright position to plug it in. Do you have any idea what is causing the frost build-up inside the refrigerator section?

Sounds like a defrost problem. Check to see if there is any frost buildup in the back wall or bottom of the freezer. If so, it is not defrosting as it should.

  • possible causes:
  1. bad defrost timer
  2. bad defrost heater (in freezer)
  3. bad thermo switch in freezer
If you don’t know what these are then unplug the machine and let the ice melt in the freezer overnight with the door open. Then try it the next day, if is cooling fine then you need to have a service person replace one of the above items.

Be sure the door seal is secure and closing tightly to prevent excessive moisture infiltration.

too much ice bulid up will stop enough cold air being blown into the fridge.Try turning it off letting all ice melt then turn it back on again and set thermostat at a lower temp.There may be ice you can't see.

You have an issue with the defrost system, either the timer, thermostat or heating element. Probably the defrost timer refer to the manual to find it. If you don't have the manual check the makers web site for a parts breakdown. You should be able to put it into defrost manually by turning the knob and see if that helps. You may need to do this sevral times as it only stays in defrost for a little over twnety minutes and run cycle for 6,8 or ten hours. If the ice build up is heavy then twenty minutes may not do the trick thus the need for repated defrost cycles. If it does the trick replace the timer. If not check the thermostat and heater element.

Look into the dispensor , and see if the door flap is closing , or letting warm air in which will cause the frost buildup . If not closing completely , remove the top cover on the freezer door hinge , and unplug the plug . This will remove power to the door . Use a small screwdriver , and insert under the freezer door dispensor control board , and pry outward . Remove the 3 plugs on the board . Next , remove the 4 screws holding the white dispensor cover , and slide outward . At the top right , you will see a solenoid and plunger , which control the door flap . Usually , this plunger rusts on the solenoid . Replace both , the solenoid and plunger ( come together in kit ) Pt # WR62X10055 . Re-assemble in reverse .

you now have a defrost issue,remove rear panel inside freezer if the evaporator is covered with a heavy ice and frost build-up then either the defrost heater under the evaporator coil is open or the defrost thermostat on top of the coil is bad you need to check both for continuity or the defrost timer if equipped or the A.D.C. adaptive defrost control is bad and not supplying power to the defrost circuit

If the defrost heating element, defrost timer or evaporater fan weren't working, you'd develop a block of ice on the evaporator. Is the compressor running?

Frost inside freezer door


there is a small electric heater along the door gasket where you see the frost building up, this heater has apparently stopped working. this will also cause the door to pop open due to a poor seal. feel around where the door gasket contacts the refrigerator and it should feel a little warm. if not then a service company can replace those heaters. should not be too expensive.

Fridge wont stay cold in the bottom.


Your frost free is not defrosting properly. There should be no ice buildup in the freezer section. Frost in the freezer section stops air circulation to the refrigerator section.
