Brandon for Model Number FPHB2899LFB Hi, I'm having issues with my refrigerator. The temperature is not correct and is changing. The freezer is also not holding temp and is changing. I am getting a HI alert on the display then it changes to a temp on the display. The refrigerator temp is 33 and the freezer is 0 but it does not seem to be holding at these temps. The ice maker is working and is producing Ice. I have replaced the thermistor however it did not seem to fix. I was going to replace the main control board next. Do you think this would be best? The control board is an expensive part so I wanted to make sure. Everything else seems to be working, compressor and fan. Thank you for your help.
Answer Brandon, based on the information provided, the most likely issue is indeed going to be the main control 242115240. It would be recommended to verify the actual temperature of the refrigerator and the freezer using a thermometer. The verified temperature can then be cross-referenced to what the resistance should be for each thermistor and the thermistors tested for accuracy. Read More...
