I have a side by side GE model GSS22WGMB. Ice keeps building up on the coils behind the aluminum wall in the freezer. I have unplugged the refrigerator, removed the aluminum cover concealing the coils, let the ice melt. clean the fridge and plug it back in. After three weeks or so the ice builds up once again and I go through the same process. What can I do to rid this problem? Any information will be greatly appreciated.
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.

The most common problem with the defrost system is a burned out defrost heater. It is located behind the frz back wall usually attached at the bottom of the aluminum cooling coils which will probably be full of ice and frost buildup. You will need to melt all the ice off the coils with something like a hair dryer. The heater is inside a glass tube and can be tested with a multimeter or sometimes you can see the break in it through the glass. In some cases there are 2 or 3 heaters at different levels. Replacement kits should include as many as needed for your model. Replace them all. 2 other parts to the defrost system are the defrost timer (usually located on the front channel under the freezer door) or the termination thermostat which is a silver disk clipped to the top of the aluminum cooling coils with 2 wires going to it. Any of those 3 parts could cause the frost buildup but the heater is the most common.
my refrigerator goes into auto defrost every 60hrs for 45 minutes or till the bi metal(defrost thermostat) says it had enough....recently i had ice built up on the coil because my defrost thermostat was stuck open...
ice builds up because the moisture that comes from opening the door or food condenses on the cold coil...tempurature of the coil is below 32 degrees which will ice up the condensed moisture...
in 601 model. really common problem is the drain hater. watch close the ice maker for a BIG long ice. on the cotton psrt of the back wall. some models have 1 some 2 depends in the serial num. ask you tech for replace the DRAIN TUBE HEATER. that way your cover. really helps a lot the code number...................good luck................. leave a comment...........thanks
There's a drain hole in the freezer side behind the bottom drawer in the back wall that must be clogh ; put hot water into it untill melted the ice and keep pouring water to clean the drain (don't worry , the water goes to an evaporative tray) .Keep the drain clean by putting every 3/4 months half a cup of clorox or bleach.
I posted this on another problem, but this may help you too. Check to see if there is frost on the back panel of the freezer. If there is try solution below: ................................................................................................ I had a similar problem. The frost in the back is an indication that
your coils are frozen. This could be from food packages falling out of
the freezer drawers in the back and blocking the air circulation vents
or maybe the freezer door was not closed completely and letting
moist/humid air in and freezing the coils. For me it was the first
problem listed.I had to completely empty the freezer and Frig. and take
the back panel off in the freezer. There you will see the coils and
lots of ice! 1. Remove all items from the frig. and freezer and unplug frig. 2. Pull all the freezer drawers out. 3.
On my GE side by side I took the light cover off and removed the bulb.
There you will see two panel screws. Remove the screws. 4. Now pull out the mouldings on each side and you should be able to remove the panel. 5. Take a hair drier and completely defrost all the ice from the coils. Be
sure to keep plenty of towels handy for all the water mess. Remember to
keep an eye on the drain tray in the back of the frig. and use a sponge
to collect the water that will build up. Hope this helps!..... Woody
The problem you are experiencing is normally a blocked evaporator drain line. Whether you have a side by side model or a top mount freezer the solution is relatively the same. Most top mount freezer models have a rear evaporator panel covering the aluminum evaporator coils. There are some instances where the evaporator coils are on the floor. These instructions are for top mount freezers where the rear freezer panel covers the evaporator coils. First of all, if there is an ice maker in your unit, this will have to be removed. Normally there are two screws which can be loosened and the body of the ice maker can be lifted off the screws leaving only a plug in harness to disconnect. Remove the harness either from the plug at the left wall or rear of the freezer and set it to the side. Next, remove all the screws securing the rear panel. Remove the rear panel exposing the aluminum evaporator coils. Be careful not to damage these coils as they contain the freon that cools your refrigerator. If you look closely underneath these coils, there will be ice from frozen defrosted water. Using a hair dryer and not a heat gun, melt all the ice and sop up the water with a towel. Now you will see a drain hole which is normally still blocked with ice. Pour hot water in this hole and sop it up. Keep doing this until you pour water down the hole and it drains into the evaporator drain pan either under or behind your refrigerator. Once you have unblocked this drain line, reassemble and plug the refrigerator back in. Set all controls to the middle settings and within 24 hours, your unit will be functioning correctly once again.

Defrost system: Freezer fan, Defrost timer, Heater, Thermostat. If any one of these are bad the coils in the freezer will get clogged with ice and not allow the cold air to circulate over to the ref. side.
Ice/frost build up on the back wall of the freezer is an indication of this problem. You can manually defrost with a hair dryer which will give you a couple of days before it starts iceing up again. Remember, the ice you see on the back wall is just the tip of the iceburg, there is a lot more on the coils behind that wall.
An Ice/thick frost build up on the back wall of the freezer if a side by side .The tank will be behind the crisper drawers you will see it frozen block of ice verses water in it you can tap it to see if the water moves.. Your water inlet valve on the disp. side maybe bad as well. Is the refrig section cooling ok??
