I have a GSS20IEMAWW that the coils freeze up

please check the defrost element and the defrost timer.

Is the freezer freezing? Do you hear a fan motor running inside the freezer? If the freezer fan is working and the freezer is still getting cold, do you see allot of frost on the back wall of the freezer?

Freezer not cooling at all - t-stat or compressor would be where to check next

No fan running in freezer and freezer is cold - bad evaporator fan motor.

If fan is running and you have heavy frost on the back wall of freezer - unit is not defrosting. could be defrost timer or defrost t-stat

Hello if you have to defrost your evaporator coils every month then you problems are (1)defrost timer(2)defrost heater (3) blocked freezer drain or many;(1) check the defrost timmer so see if it is working the defrost time is from 15-25 min depending,And durning this defrost time you may hear the sound of ice melting on the heater a sine that the heater is working .(2) Blocked freezer drain,The water from the defrost cycle sitting in the drain pan,Is being picked up by the fan pulling it with the air back through the evaporator coil a second time freezing quickly ...

your evaporator coil in the rear area behind the freezer back panel is frozen over with ice and the coil can no longer deliver cold air due to ice blocking the air flow from the evaporator fan,remove this rear panel,defrost it with a hair dryer,check the defrost heating coil for continuity,they go bad regularly,if not the heater coil under the evaporator coil,it may be the defrost timer in the refrigerator section of the unit that powers the defrost coil that needs replacement

either defrost timer, t-stat or heater is bad. either way it is worth repairing.

If you only had ice buildup in one section of the evaporator you have a weak/inefficient compressor.
You need a new compressor or a new refrigerator.

Sounds like the defrost timer is not tracking the time properly. The unit needs to defrost once every 6-8 hrs. in order to work. Make sure the inside (evaporator) fan is running ok. If it rund for a few days and then warms up in the refrigerator section (coil iced), then the defrost timer is the culprit.

Hi, are you getting ice or frost build up.
The most common part that goes bad on these are the defrost heaters. THe defrost heater is below the evaporator coil and usually has a blue and pink wire to it. Test the heater for continuity. If it tests open, replace the heater. If it tests closed, check continuity on the bi-metal stat located on top the evaporator fast to the coil. The bi-metal stat has to be tested cold. Again, if it tests open, replace it.
If both of these test ok. you wil need to replace the defrost control.
Please let me know if this has helped you or if I can assist you further.

Thanks
Vic

if the fan is not running then most likely the defrost stat has failed but you should also check the fan for continuity if you have continuity the fan should be ok you can find a defrost stat on parts advantage.com

PLEASE DISREGUARD GUEST FIXYA SOLUTION,FREEZER PROBLEM PROCEDURE IF NOT DEGITAL,FIRST CHECK IF ICE ON BACK FREEZER WALL. STEPS-FIND DEFROST TIMER,BOTTOM FRONT ,BOTTOM BACK, INSIDE FRIG.ON CONSOLE,LISTEN TO SEE IF FAN IS RUNNING IF SO TURN THE DEFROST TIMER CLOCKWISE TILL YOU HEAR A CLICK SEE IF FAN TURNED OFF IF SO YOUR FREEZER IS IN DEFROST,FREEZER WILL COME OUT OF DEFROST IN 20-30 MINUTES IF IT DOES AND THE FAN COMES ON YOU HAVE ELIMINATED DEFROST TIMER&FAN,NEXT REMOVE BACK PANEL TO FREEZER IF THERE IS ICE FORMING REMOVE BOTH LEADS TO HEAT AND CHECK WITH VOLT METER ON OMES,IF YOU GET ANY READING THE HEATER IS GOOD,IF NO READING REPLACE HEATER AND CLIPON TEMINATOR,IF HEATER IS GOOD DEFROST COILS WITH HAIR DRYER TOP TO BOTTOM AND THIS WILL ALSO CLEAR THE DRAIN,IF EVERYTHING CHECK OUT GOOD DEFROST TIMER ,FAN ,HEATER, DRAIN, YOU NEED ONLY TO REPLACE THE LITTLE ROUND CLIP ON TERMANATOR,LET ME KNOW-MIKE
