Skiz for Model Number PSS25SGNABS I have a GE PSS25SGNA/SS. The unit works great when I first plug it in, but after a few days, starts to experience wide temperature swings. Eventually water and ice are building up in the freezer section. I have already replaced the board, and did not clip or make any modifications, as my specific model was not called out. Since it seems fine when I first plug it in (temperature falls to set points), I'm thinking the issues may be around the defrost cycle. So I was thinking of replacing the defrost sensor. While I'm in there I think it would be smart to replace the other temperature sensor(s) since the unit is 12 years old. How many do I have, and is this a good idea? Do you think I'm on the right track with the defrost sensor?
Answer Hello Skiz, You need to check the defrost heater and the sensors. These can be checked from the control board. It is good that you did not clip any wires since you were correct in your interpretation of the instructions and no modifications should be done for your unit. I would also make sure the door seals and ice door are closing and seating properly in addition to verifying the voltage and polarity at the outlet. This actually sounds like a relay issue on the board. I know you said you have replaced the board but the new one could have issues, especially if you find the outlet is not wired correctly.
