Review on General Electric WR55X10025 Temperature Sensor by Bill Dahl

My GE side-by-side PSW23PSSCSS has two of these temperature sensors in the freezer and two in the fridge. Internet gurus have pointed to temperature sensors as a likely cause of cold store evaporator coil icing. (This fridge has a complex control system with separate coils for the fridge and freezer compartments; simpler systems just bring cold air from the freezer side.) If this fix doesn't work, the following recommended steps are: $300 circuit board replacement -- First, I'd go over it think about throwing away the 10 year old device. I thoroughly thawed the coil, removed its plastic/foam covers and removed it from the back of the fridge. Be careful; The "evaporator cap" is a fragile foam baffle encased in a hard plastic sleeve. When diagnosing this freezing issue, the foam broke into several pieces and detached from the plastic cover. I fixed it with kitchen caulk/glue and tape. One of the temperature sensors is located about halfway up the left inner wall of the refrigerator, next to the freezer compartment. The old sensor popped out easily, I cut its wire and screwed on the new sensor with small nuts. I then sealed the exposed ends of the wire nuts with silicone, wrapped the splices in electrical tape, and reattached the sensor to the wall. I don't remember exactly how many ohms.) So I think the original door temp sensor was probably fine and didn't need to be replaced. The second sensor is located behind the evaporator coil. Remove the evaporator mounting screws, then gently pull the right side of the coil forward. A stable aluminum sensor holder is attached to the back of the sensor. Cut the zip tie and pull out the sensor holder so you can grab hold of it. A rubber stopper holds the sensor probe in place. Remove the old sensor and use the skills learned above to connect the new sensor's wires. Before installing the new sensor, I cleaned the aluminum part with denatured alcohol. The rubber stopper fell apart so I used some silicone to help it hold the new sensor in place. Thread a long piece of plastic tape through the spools and use it to secure the sensor. Put everything back together and you can restart your fridge and see if your fix worked. The original refrigerator coil temperature sensor has changed color. When I tried to measure its resistance, I got readings everywhere. Jumping from infinity to zero. I hope I have identified and replaced the defective part? A month has passed; we had high temperatures and humidity; the coils are not frozen! HOORAY!
