Wanda for Model Number GSS25QGTABB Refrigerator about 6 years old. Beeping randomly while displaying error code tc. Replaced main control board 5 days ago and beeping and tc code just returned. Temp is set at 0 and 37 but temps are usually registering random numbers. Freezer anywhere from -9 to 1 and fridge anywhere from 39 to 34. Is the next step to replace the temp sensor? And if so, do I replace all three.
Answer Wanda, You can test the thermistors on the unit to make sure that they are good. The resistance rating of the thermistors are as follows: 5K ohms at 77 degrees, 14.4K ohms at 37 degrees, and 42.2K ohms at 0 degrees. If not within range then replace the thermistor. Read More...
