If your refrigerator has ice build up on the inside, here are a few things you can check yourself to fix the issue. A common cause for ice buildup is a faulty door seal. If a refrigerator has a bad door seal, the outside air will pass into the fridge and cause the ice build up problem you are experiencing.
Another cause for this could be that the door hinges are loose or not attached properly leading to outside air entering your fridge/freezer. Check to be sure the door hinges are tight and are attached and aligned properly.
Some other simple things you can do to try and remedy this issue are easy to try yourself. You can try moving the refrigerator away from the wall a little bit more to give it extra room for the air to circulate. The heat from the compressor should have sufficient room to dissipate. If the refrigerator is too close to the wall problems will occur.
Another solution may be to clean the vents on the back or below the fridge as they can be clogged with dust and debris. Clogged vents cause air circulation problems that lead to many common refrigerator problems.
If the ice build up is only happening in the freezer, the freezer drain is probably clogged. To unclog the drain you should first unplug the unit from the wall. Remove the freezer covers to expose the frozen drain. Pour hot water down into the drain hole until you see the water dripping into the drain pan under the refrigerator.

How to unclog a refrigerator defrost line
Modern day refrigerators are frost free. They should not have to be defrosted manually. If however you have an older refrigerator or you want to manually defrost your newer fridge, here is how:
- First remove food and store it in another fridge or cooler.
- Unplug the refrigerator from power and remove any drawers or shelves.
- Wedge the door to keep it open for the defrost procedure.
- Lay a deep pan or similar at the bottom of the refrigerator to catch the water when the ice melts.
- Leave everything sit until all the ice has melted (this is a good time to wipe down the inside of fridge).
- After the refrigerator is defrosted and the ice is gone, clean and replace the drawers and shelves.
- Plug in the refrigerator back into power.
- Set the thermostat dial to be sure the temperature is set correctly.
- Shut the refrigerator door.
- Once the fridge is cold you should watch for any ice buildup.
- Check to be sure the fridge is at the proper temperature and no ice has formed.
- Put the food back in the refrigerator.
- Periodically check fridge to be sure no more ice has formed.
If your refrigerator is still under warranty, make sure to call the company you purchased it from or call the 800 number of the company who manufactured it and schedule service. Find out if it is under warranty before doing repairs as doing repairs yourself could void the warranty on the unit.
NOTE: At times a powdery type of ice will form in your refrigerator if it is being repeatedly opened and closed. Keep this in mind as your only issue may be this and no repairs are necessary.
Other things causing this issue could be a defrost timer, bad temperature sensor or bimetal defrost thermostat. In this case you will most likely need to call a repair person or find someone who is experienced with diagnosing appliance faults and removing and replacing components.

I have a GE side-by-side I have ice build-up inside the freezer I changed the heat element on the thermostat I’m still doing the same thing I don’t know if you could help me with an answer thank you so much
I solved this problem on my kenmore. This should work on most brands of modern refridgerators. All refrigerators have an air intake and a lot of makers put them at the worst place, at the bottom of the unit. So all you have to do is take the front grill off at the very bottom of the fridge. and suck out with your vacume wand all of the lint that is blocking the air flow. Melt the ice with heater or hair dryer on low so you dont melt the plastic inside of fridge and plug it back in it should solve your issue..
I have a BEKO fridge no frost Freezer, I have notice that the fridge is icing up on the back wall in the middle of the fridge. I have emptied it out once already and left the fridge off for 24 hours getting rid of the ice, I have emptied the water tray at the back of the fridge but now a month later it is happening again. Can someone please help. The temperature is set at four as I found that things were not keeping very cold in the fridge but at four it is perfect.
I have a 4 year+ old Bosch fridge freezer ( KGN39NW20/01). Over the month or so very thick blocks of ice are buiding up at the bottom of the freezer. I note a white coil at the back – is it a waste pipe clogged? Or a mechanical/electrical fault with evaporator?
My Maytag refrigerator freezes in the door mainly at the top.
Gasket was changed, coils are clean, but the ice builds along the 2 trays on the inside of the door and have condensation in the containers storages in the refrigerator.
The technician said that the temperature control need to be changed.
The refrigerator is about 10 yrs old.
I have a Kenmore side by side refrigerator/freezer model no. 106.56532400. Ice forms on the bottom of the freezer, so I turn the unit off, take the food out of the freezer and melt the ice with hot water. When I see water dripping into the collection pan in the back of the unit, I put everything back together, add the food and plug the unit in. I have done this several times but the ice continues to build up on the bottom of the freezer. The vent to the refrigerator is clear. Dust is not the problem. Any suggestions?
