Bottom mount GE Fridge evaporator fan plugs with ice once a month

1998 GE Bottom Freezer Fridge, model # TCX18. About once a month ice builds up in the air circulation void and eventually plugs up and falls into the evapourator fan and makes a clinking noise. After enough build up of ice it eventually falls into the fan and if it is not deiced the fan will actually stop. The tech has been out twice to check it and both times the 'fix' didn't work. There are no clogs or blockages and all line are clean. PLEASE HELP!

    Exact same model fridge and exact same problem except fan is iced up about once a week. Thoughts are that a) cooling kicks in too fast after defrost cycle causing ice to build up in thin layers over time at the drain causing an eventual drain blockage and fan seizure...or, b) air circulation fan is pushing air in the wrong direction - i.e. pulling air over the cooling coils and then blowing it up through the back vent to the top of the interior, rather than pulling warmer air from the vent and then blowing it over the coils and out through the front bottom vents. In the b) option, this air would be warmer when it passed over the drain hole.

    We have the same problem-only difference is ice build up is every 3 weeks causing the fan to be blocked by ice and stop. Can someone please confirm the circulation direction.

    I got this problem once. The tech came, cleaned out the plastic plug at the back as it was clogged. Now the ice builds up again avery month and a half. The has got to be some reason for recurring buildup. Something blocked or malfunctioning? I also added a sheet of aluminum to further isolate the freezer and fridge sections as the bottom of the fridge (fruits and vegetables would tend to freeze! Tech told me it was a cmmon problem due to insufficient insulation. Look forward to hearing of anyones solution.

SOURCE: Evaporator fan stops working due to ice buildup around fan.

you need a drain tube heater.it is like a chain fence tie made from alluminum,you can actually use the fence ties,wrap one side around defrost heater and stick the other side in drain.that will prevent it from happening again

Temperature control


The freezer is usually cooled by the compressor, the fridge is then cooled by an evaporator fan motor ($30). If this fan seizes or slows down then the fridge warms up (it sometimes starts squealing before this happens). The fan may spin, but it if goes too slowly, then it would blow enough cool air into the fridge, especially if it is opened quite frequently.

If you think it is the evaporator fan motor:
Check to be sure you can get a replacement fan first, they last about 4 - 5 years. Can get from a parts supplier or electric motor company.
UNPLUG fridge. Located usually in top of freezer behind a vented cover plate. Remove cover, remove screws holding fan in, may have to cut wires. Replace with new motor, make sure the fan pushes air into the freezer area and doesn't spin backward drawing air from the freezer area.

The freezer motor starts whenever I close the freezer door. It is loud and sounds like something is hitting a fan.


The evaporator fan motor inside your fridge is constantly trying to keep the temperature you have set it to. when the fan is on it circulates the cold air from your freezer in to your fridge. if you hear a banging noise it is cause by the fan hitting a build up of ice. this can be caused by a clogged drain pan or tube, not allowing water build up to be drained, or you could also have a defrost heater issue in which case you would have a large build up of ice near your fan. you can access the fan motor by removing the two panels at the back of the freezer, once removed you will be able to see whether or not there is a ice build up.hope this helps you
Thanks.

GE Refrigerator is too warm, from the 80's, top mount freezer. The freezer seems to be working fine but the bottom fridge part is warming up. The dials are set to maximum coldness selection.


Hi, With the information you supplied i'm going to assume there is an ice build up at the rear of the freezer. Your problem is going to be with your defrost system. I will also assume you have the ability to repair this yourself. This is going to be one of three problems with your refridgerator, 1st thing to do is remove shelfs and panel in the bottom or back of the freezer(depending on what model you have)...you should see ice build up on the evaporator...don't worry get a hair dryer and melt the ice. Next locate the wires for the heater...using a multi meter test the heater for condinuity...if the heater is bad replace it, If the heater is good replace the defrost thermostat..the stat normally is a barrel looking part clipped onto the evaporator pipe. The last possible problem could be the evaporator fan, have you heard the fan running in the past few hours?..if you are not sure pull the panel out to where you can see fan and watch it over an hour to see if it turns. I have included links with pictures of what the parts you need to check are: http://romulusappliance.com/manufacturers/maytag/refrigerators/575432.JPG defrost stat http://www.hotekalliance.com/UploadFiles/2008627111553382.jpg heaters http://www.applianceblog.com/archives/EvapMotor1018185.jpg evaporator fan. Hope this helps. If you have any other questions please feel free to comment again. If you decide to get a repair guy in should not cost you any more then $120 - $200 depending on make/model/problem Good luck & thanks for using fixya!

Fridge autodefrosting but condensation not draining away and evaporating causing a build up of water in bottom of fridge section


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.

Evaporator Fan Motor noise is excessive for this refrigerator. GE Profile CustomStyle Model PTI22SFMARBS Serial# SF900146V


Despite my urge to vent about GE refrigerators, I'll keep this short.

If you have a constant squealing noise from the evaporator fan in the freezer, there's a good chance the fan just has failing bearings, and replacing the evaporator fan might solve the problem.

But if the noise is intermittent; quiet sometimes but sometimes buzzing loudly, then my bet is there's nothing wrong with your evaporator fan. It's a problem with the design of GE fridges: They don't defrost completely. So ice builds up on the back freezer wall, etc., and on and around the evaporator fan. That's not a problem when the fan is in "low speed mode". But open the door, get the fridge warm, and the fan kicks into "high speed mode". That's when the noise will start, as the fan blades and assembly warps under speed to hit ice and start vibrating.

Acid test is this: While the noise is occurring, turn the fridge temp (not freezer) control up as high as you can without turning off the fridge. That will make the fan shift into low speed. If the noise stops, you got ice on the fan, my friend.

In that case, unplug the fridge, and get a hair dryer and blow warm air into and onto the evaporator fan area. Maybe gently whack the fan area with your hand a bit, to knock the ice off. Once you get all the ice off, turn it back on. If it runs on high, without any noise, the problem is fixed ... until the next set of high humidity days. I plan to post a video about this, once I get it edited to remove the expletives. ;-)

GE will sell you a "moisture kit" for $340, which may fix the problem, but only if your fridge is out of warranty.

If your fridge is still under warranty, GE will tell you there's nothing wrong and that maybe you just need ear plugs.
