Frankie for Model Number GSS25SGPASS

The evaporator fan stopped working. I changed the fan and main board. The compressor started together with the two fans, about an hour of running the compressor shuts down. More than five hours later the compressor does not restart only the evaporator fan keeps running. I unplug it for about an hour. Plug it back it still do the same shut down after about an hour and never restart. What could be the problem? I hope you can help me. Thank you.

Hello Frankie. Based on the information you provided, if the fan motor and the main board are good, then the compressor WR87X10226 is bad and will need to be replaced. Test and see if there is power coming to the compressor. If so, and it is just clicking, then you let it sit and it runs, replace the compressor. Hope this helps.

David for Model Number PSS25MGNAWW

Follow up question. When I do the self test I get on the freezer read out a "P" and on the FF side I get 12345 during the test it reads out like this p1, p2, p3, p4, 05, now that would show a failed thermistor on #5 which is the freezer thermistor right? I replaced the freezer thermistor and reset the unit and then ran the test again and still the same results pass on all of them except the freezer which I still get a "O5". How can it still be failed if I just put a new one in? Checked all of my connections and everything is tight. Any help with what to do now? Thank you

Hi David. There are 2- thermistors in the freezer section. Part # WR55X10025, for evap. one. Part # WR55X10025 for middle area in the freezer. There are 2 - as well in the fresh food area. Same part #'s. Crisper and upper control/damper area. When you pressed cold,warm both freezer and fresh food to enter the field test, did 0-'s appear in both areas? If so did the blinking 0's change to solid 0's? Just confirming. The thermistors are controlled by algorithms sent from the main board. Yes, 0-5 means the freezer thermistor has failed. Your connection needs to be tight and back filled with silicone so no moisture will impede the connection. You may have only replaced one thermistor and change the other as required. Thermistors have been upgraded as a whole and last longer these days. Thank You.

Just a quick follow up question... If you have a failed freezer thermistor will that make the damper motor run non-stop? I had the damper problem with the broke damper door and bought the new part but the damper motor runs non-stop. I can hear it when the rest of the refrigerator is not running. I can put my ear up to the side and hear it running. Just wondering if the failed thermistor has anything to do with that? Thanks and keep up the great work you guys do for us all who need help and are trying to save money. David

Hi David. The thermistors tell the board @ cavity sensed temperature's. If open or shorted it will automatically put the defrost circuit in an 1-hr. forced defrost. The thermistors will not act as you said w/ the damper. Did you get the damper assy. part # WR49X10091? Possibly the wire connections need double checked per colors. Make sure there are no pinched shorted wires. If the part needs exchanged, we will stand behind it. Please see your instructions per part. Please call 1-877-477-7278 A.P.P Call Center. Thank You.

Hello David. Yes, WR55X10025 is the correct thermistor for the model number you provided. The thermistor reads the temperature inside the freezer, and there is one on the coils that works the defrost cycle. They are made to read the temperature and send it to the control board using an ohms value reading. If the code says it is bad, you will need to replace the thermistor. Hope this helps.

Susan, Life expectancy on electrical components, especially PCB's(printed circuit board) can't really be determined, there are too many outside influences to consider, proper, constant voltage, polarity, wiring, environment, etc. on occasion a failed component, can and does damage a PCB. On average, and under the proper circumstances, I'd expect a PCB to last at least a year, and as long as 5, under proper conditions. good Luck and Thanks

Hi Russell. You will need the thermostat/harness assy. Part # WR23X10209. The fresh food thermistor is part # WR55X10025. These parts work in conjunction with each other. Thank you.

Hello Frank. If your serial number is ZA2, and not ZD2, then you do not cut the wire. Here is the list of serial numbers we have for the wire to be cut. ZD2 is on this list. Hope this helps. ENCODER models with the following serial number prefixes: TD2, VD2, ZD2, AF2, DF2, FF2, GF2, HF2, LF2, MF2, RF2, SF2

Frank H for Model Number GSS20IEMBWW

Have a follow up question...to my previous... When I installed the new mother board, I noticed that the evap fan began running immediately with the either door open. With previous mother board the fan only ran when the doors (both doors) were closed. So far, i have purchased and installed new mother board, heater, and heat sensor. Evap fan is next. Ran good for about two weeks and frosted over again. Suspect fan may be sticking or quits and then it frosts over. Instructions with mother board said to cut the wire in pin 2 of the J1 connector, but list of models on instructions did not include my model GSS20IEMBWW. Just want to be sure and confirm that wire does not need to be cut for my model number... Also, does the evap fan run all the time, or does it shut down sometimes depending on temperature or if it goes into defrost cycle. I opened the door the other day and noticed fan was not running.

1 Answer

Hello Frank. You will need to look at the first three letters and number of your serial number to determine if the wire needs to be cut. Not the model number. If it needs to be cut, this can solve the problem your having. The fan motor does shut off if the temperature is correct or in the defrost cycle. Hope this helps.

Hello Frank. If the fan WR60X10185 is not running, it will cause the coils to ice over. It sounds like you found the problem. Hope this helps.
