My refrigerator frist stat can running to my set up the temperature, then stop, after that, not running anymore. which part I need to change to fix?
For model number RB1944SL
Hi Louis, thank you for reaching out. The issue could be with the temperature sensor, part number PS4138683. You may need to replace it to fix the issue. We hope this solves your problem!
Hello Bobby, thank you for your question. We would recommend testing/replacing the evaporator motor and the temperature sensors in the fridge. One around the evap motor and one by the evaporator itself. If that isn't the issue, we would recommend checking the defrost heater, thermostat and main board. I hope this helps.

My fridge is stuck on “Fd” and I’m not sure how to fix it. Also, when it works the freezer doesn’t freeze my items all the way or reach a certain temp. It says “0” but doesn’t seem like it really is
For model number RB1944SL
Hello Jarelle, thank you for writing. To correct the FD you will need to : Press the correct buttons until FD appears on the display then cycle through the various options (by, for example, pressing the Fridge button) until you come to the blank option – this will turn it back off. We hope this helps.

I performed the repair to my own refrigerator, after watching multiple YouTube videos. I installed a secondary heater for the defrost coils and replaced the defrost sensor. The defrost sensor was actually bad. Today, 1/27/2024 I rechecked the fix from last week. All seems to be good so far.
If I get any build up of any ice on the bottom tray of the recessed panel where the drain port is located. I suspect I will also need a new Defrost Heater as well. For now the refrigerator is operating as expected. There is a small amount of ice build up as of today.
Also, I had recently replaced the drain tubes, added a longer heater element part to fit the drain hole, and cleaned the fins in the back of the refrigerator. Thank you.
A couple of blogs said the freezer defrost sensor should be replaced, so I ordered one. Did not fix it. I did, however find a service manual online and one of the blog sites and it showed me how to remove the inside duct work. I discovered the fan the recirculates the air across the evaporator coil was not working. Ordered a new fan motor and installed it, fridge works perfectly now.
Took off the plastic panel in the interior. As usual, the evaporator was completely iced up. Took most of the time to de-ice it with a heat gun. Tested the components and the temperature sensor was bad which is on the top end of the evaporator fins. The ohms test wasn't any different whether hot or cold. I keep a spare sensor on hand because this is the third time one of the sensors have failed. The proper readings are available by doing some internet searching. Its been two weeks since I worked on it and everything is working fine.
