refridgerater side warming, freezer warming
First I diagnosed the problem being a defrost timer as the symtoms are the same as the heater elements. I installed the timer and it worked great for about a week until the frost build up on the evaporator became too much again and then the symtoms returned. I then checked the heater elements and found that both were bad PLUS two clips to the elements were corroded. I then ordered the 2 heater elements. There is more than 1 heater element. Make sure you measure the length of each and then use the graph picture with "Parts Select" on the new ones before you order. There is about a 2" in length difference. Also one comes in a kit with thermostat and wires. Wrong for me. I really wanted that unit as I needed the harness for the bad terminals but it was the wrong heaters and it also came with a new thermostat. Luckly I did not order that one but did order a new thermostat to make sure I did not have to go through this ordeal again. When the parts came I had already replaced the terminals and was ready to go when FedX came. Just make sure you check your heaters before just buying the defrost timer as it may keep you from going back to redo your repair. Just doing your home work before ordering may save you much time in your repair. "PARTS SELECT" was one day on both orders and I just ordered standard shipping. They are great to do business with.

ref/freezer would not maintain proper temp. Ran all the time or would not come on once it quit running. Freezer would get too warm or ref. would get too cold and freeze contents.
1. Unplug, remove control knob from both temp control sliders, remove upper light bulb and light shield from refrigerator compartment. 2. Remove screw holding top of bracket control mod in place. 3. Lift bottom tab from slot and remove control mod from ref compartment. 3. Unplug temperature control and defrost timer and replace. (Each are held in place with two screws.) 4. Replace control mod. This part took me the longest because the space between the top of the control mod and the top of the ref. compartment is very small and replacing the nut was difficult. Use a nut driver with a long shaft. 5. Use screw driver to turn control button of defrost timer to start cycle. 6. Replace bulb cover and light bulb. 7. Set temp control to initial setting. 8. Have a Margarita and celebrate. It's been over a week and the refrigerator/freezer is working perfectly.

refrigerator compartment got warm
After a little research I realized my problem could be one or possibly two components of three that caused the problem. Instead of changing one at a time, I took another approach. I just bought and changed all three to save time and prevent having to do the job all over again. Each time I would have to melt the ice off of the cooling coils and this is time consuming and annoying having to melt the ice repeatedly. I put a very accurate thermometer in the fridge and have been monitoring it since I changed the components. After one week it seems to be working fine keeping the fridge at 34-38 degree F.

Refrigerator not cooling enough
I first googled the problem, then narrowed down the parts that could cause the problem (if failed), then took out the parts and determined that they had indeed failed. I then ordered said parts and installed them. It was easy because they are "plug and play" parts. The hardest part was removing (and then replacing) the back panel inside the freezer just because it was awkward to reach the screws.

icemaker stopped working,warm fridge,
first i entered the symptoms into your site and the culprit was gonna be the defrost timer or defrost heater-thermostat. I ordered the parts and they arrived the next day even though I didn't pay for next day. Defrosting the freezer was what took the time.After it was thawed it only took about 15 minutes to install the heater and timer. Am happy to say I have all the ice I need and your diagnosis was right on.

Freezer icing up - refridg too warm
I viewed the online video, which really is helpful.

Most of my "repair" time was defrosting the freezer coils (about 1 hour).

After removing the freezer shelves and access cover the thermostate and heater were in plain sight.

The heater is held in place with two phillips head screws and two wires that unplug (one on either side of heater).

The other tools came into play when removing and replacing the thermostate. Cut the two wires and strip for wire nuts, same with new thermostate. Wires color coded. I use electrical tape after appling wire nuts to seal the nuts.

I ordered a timer but found out, after research, that my model has the timer interagrated on the motherboard (main electrical board) (like in a home computer). So I returned the time for refund.

Super fast delivery of ordered parts. I ordered one evening, they arrived the next day.

Warming of the freezer section above 15 degrees
This actually was a part of a thermostat problem. I bought a thermostat one week earlier and that fixed the problem. I bought the thermostat thinking that was part of the warming of the fresh food and freezer section. I installed the defrost timer anyway with the thermostat and it is working well. I didn't know that the freezer got above 15 degrees on the defrost cycle every 16 hours.
One 1/4 hex screw at the top of the housing removes the entire assembly. Be careful not to damage the foam on the left side removing the housing. There is a tab on the bottom right on the back panel that lifts up to remove. Unplug that whole assembly from the fridge wiring harness and the rest is obvious.

We tested defrost heater already and there was no problem with the heater. How to test the defrost timer? Thanks.
For model number Csx22gayaww
PartSelect logo
Hi Christine, Thank you for the great question, Step 1: Unplug the refrigerator. Step 2: Disconnect the wires from the timer and timer motor. Remove the timer from its brackets by backing out two retaining screws. Step 3: Test the defrost timer with a VOM set to the RX1 scale. Clip one probe of the VOM to each defrost timer -- not motor -- wire, and turn the timer control screw shaft until it clicks. If the defrost timer is functioning, the meter will read zero. If the needle jumps, the defrost timer is faulty. Replace it with a new one of the same type. Step 4: Connect the new defrost timer the same way the old one was connected. Hope this helps!

Freezer cold, but refrigerator warm
For model number TFX22JWXDWW

Hi Jim, Thank you for your question. There are a couple of parts that could cause this issue. Your defrost timer is one of them. I would also suggest checking our your defrost heater, defrost thermostat, and your run capacitor. You can test all of those parts with a multi-meter. Good luck with your repair.

Hi Stewart, Thank you for the question.I suggest testing the relays on the compressor. You can check for continuity with a Multi Meter. If there is no continuity they will need to be replaced. Hope this helps!

My refrigerator is running all the time and things in the freezer are not freezing completely.The outside of the freezer section near the door has a hot strip that runs most of the length that i can get to. i have went through your site and read reviews and watched the videos. everything points to the defrost timer. i get the "hot strip" so i'm thinking the defrost heater is good. the hot strip goes off and on, so i'm thinking the defrost thermometer is working. i guess i just want to be more than 90% certain that it is the timer before i order one. i haven't done any testing yet. is there a quick way to test the timer to see if it is working correctly? thanks, mike
For model number tpx24sry

Hi Mike, Thank you for your question. The defrost timer does fix the issue the majority of the time. This device acts like a clock. It continually advances and alternates between activating the cooling cycle and the defrost heater. To verify if this is the part that is causing the issue, you will need to test it with a multiemeter. If it tests fine, then you will need to check the run capacitor and the defrost thermostat. I hope this helps. Thank you and have a great day!

Wear do you find the defrost timer before I start breaking covers? This is a bottom freezer, is the timer inside the temp controls?
For model number GBS20KBRCWW
PartSelect logo
Hi Garth, thank you for the question. Your model does not come with a defrost timer. The main control board, part number PS2364946, manages the functions of the refrigerator, such as cooling and defrost times. It is located inside the rear cabinet cover. We hope this information helps!

I have tested the new defrost heater & the defrost thermostat ,both have continuity. I'm thinking it might be the defrost timer . My freezer gets to about 25-35 degrees .What is strange is only the lower portion of the condenser coils freeze up and the upper half does not. Is it the problem or is there something else causing this issue with my refrigerator & freezer.....
For model number TFX25JPCEWW

Hi Arnold, Thank you for your question. That would be my third guess. You should be able to test your defrost timer the same way that you tested your defrost heater and thermostat. I hope that helps. Good luck with your repair.

Good day.I had a refrigerator GE model tfx20nw. i had a problem with the timer and the thermostat bimetal. the parts are being replaced but the freezer refrigerator still with the same issues. therefore im interested buying the replacement parts. im interested getting the timer and bimetal thermostat but i would like to know if all the timers have all the same cycles 6/ 8 hours frozen period and 30 min of defrozed cycle and also if i need a bimetal thermostat of the same size proportion of the original piece. the fridge has a new bimetal but i would like to know if it is a problem by using a bimetal of different size or brand. the bridge is kind of old so its very hard to find the original GE pieces and i would like to know your recommendations and what GE parts should i get for my model. thank you for your time and information. best.
