Scott M. May 01, 2014 for Model Number tfx24ejb Continueing "DE "! tfx24ejb I have replaced the defrost thermostat.I checked continuity on both heaters in the freezer,and checked the timer,all functional. 48 hrs pass,i hear a sound like a woodpecker 3 times then the DE flashes. Twice this exact thing happens. I unplug the refridge,wait 5 minutes,replug the refridge back in and the DE clears for another 48hrs! When it starts all over again. I must be resetting the control panel by doing that but until that sound reacures 48 hrs later ,same sound,same result! What is next?
1 Answer Scott, Based on the information provided the issue would most likely be caused by the defrost timer if the unit is not going into the defrost cycle. If the unit is going to the defrost cycle the issue would be caused by a control board that is faulty. Read More...
Scott March 10, 2014 for Model Number tfx24ejb I have a diagnostic panel and after several attemps to clear the " DE " continues to flash. Would that be that the defrost thermostat is not working? Maybe the timer? Fan runs and it is cold and holding.
1 Answer Hello Scott. The DE error means that there has been no current flow through the defrost circuit in 48 hours. It can take up to 4 weeks for this to become a problem that you would notice. After you clear the code the code will reappear after another 48 hours. The common causes for this is open defrost heater WR49X392 or open defrost thermostat WR50X55. You can test to determine the faulty component using a meter for continuity. Here is a link to our repair forum that will describe it in more detail.

Crystal October 20, 2013 for Model Number GE TFF24ZBC The refrigerator has failed but the freezer is functioning properly. Could this be a thermostat problem?
1 Answer Crystal, With the refrigerator section not working but the freezer still working then you will want to check and see if there is any frost build up on the back wall of the freezer. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
Neal July 27, 2013 for Model Number GE TFK20KJB Why are both wires the same color on the WR50X55 defrost thermostat? How would I know which wire to connect to which color wire on the harness? And do the instructions for changing the bracket come packaged with the thermostat? Thanks for your help.
1 Answer Hello Neal. This is a closed circuit and does not matter which wire goes where on the harness. As long as they are on the old thermostat wires. Read More...

Mark March 30, 2012 for Model Number Fridge freezer CSX20ERAWH (approx.20yrs old) Hi. The contents of my freezer was thawing out and would refreeze. Loads of ice on the back panel. Discovered charred wire to lower heater element, repaired same but heater would not come on during defrost cycle. Removed defrost thermostat and heater now works. However original symptoms persist. I am going to order a thermostat but as defrost timer seems to work oK. I thought freezer should behave OK. Condenser coil is well frosted up and temp in freezer is approx. -5deg. C and the fridge wont go below +8deg.C. The cover over the fan /coil unit is removed for now. Q1. Would this affect the performance of the fridge due to the way the fan circulates cold air from freezer. Q2.Will a new thermostat restore my fridge to correct working condition?...Thanks..Mark
1 Answer Hi Mark. The defrost thermostat has to ohm closed (o-ohms) at 0°. It may check OK, but then fail to perform under the normal operations mode because of internal contact arcing issues. It also as importantly has to open to protect the cabinet from melting and also from freezer food burn. Defrost part # WR50X55. The defrost timer will control the 6-1/2 hrs of compressor run time and then the 20-25-minutes of defrost occurs. Part # WR9X482. No, the evaporator coils cover directs the coil air with the evaporator fan properly in a side and front circulating manner for proper performance. Thank You. Read More...
Tom December 16, 2011 for Model Number FRT18SJGW1 I have a similar temperature fluctuation. Ice tray ice melts, then mostly freezes and starts to melt again. We have to have the coldest setting on the temperature control in the fridge section to get it to perform this way. I haven't tested that control yet. The fan inside the freezer compartment seems to run fine. Ducts are clear. There was no frost on the freezer compartment coils when I pulled the internal cover off, although a week or two ago it may have frozen up when we found the door cracked open overnite. There was a good amount of water in the condensation tray over the compressor when we first discovered the melted ice cream the other day. I checked the defrost timer with an ohm meter and switching works, 1-3 coil terminals check ok--compressor off for 20 minutes as expected when installed and tested. Compressor runs with normal hum, but is hot to the touch--can only only handle heat with hand for 5 seconds. The coils are mostly dust free on back face of unit, not underneath where the compressor is. There is no cooling fan for this model's compressor. Is it supposed to run that hot? I don't hear any unusual noises. I took the starter overload off and shook it--there was no rattling. Any ideas what is going on here? We just filled the freezer recently (Vents are not obstructed). Help! lol. Thanks.
1 Answer Hello Tom. If the unit needs to be set on the coldest setting to do this, it sounds like the problem is in the temperature control 5304404821. Hope this helps. Read More...
Joe August 06, 2011 for Model Number TFX24ZLL Suddenly, our refrigerator's temperature fluctuates from 50 to 56 and our freezer fluctuates from 20 to 38. Do I need a new Defrost Thermostat (Diagram #240), Control Temperature (Diagram #424) or a Control Defrost (Diagram #257)? Also, fan (Diagram #650) is not working. Any connection? NEED HELP FAST!! Thank you in advance.
1 Answer Joe, What gives you the impression the problem is a defrost failure ? do you see ice or frost on the freezer back wall, when the refrigerator temperatures get warm ? That's a better indication of a defrost issue. It could be an issue with the evaporator fan WR60X30349, it could be the fan motor is stalling or running slow,not circulating the air. It could be that you have a clogged, dirty condenser and the fridge system is not transferring the heat properly, and there are more possibilities. Thanks and Good Luck. Read More...
1 Answer Hello Jesus. Here is the link to the parts diagram, refer to part 257 for location of defrost timer WR9X482: http://www.appliancepartspros.com/partsearch/model.aspx?model_id=203584&diagram_id=20703727#d20703727 . This looks like the bottom rear of the unit. Hope this information is helpful, thanks! Read More...
