The fridge is getting cold enough to freeze things, vents inside and out are not blocked, even though temp setting for fridge is at its highest at 44, but temp showing on screen says 80, is this something fixable by changing the main pcb control board?
Cmcdfly, thank you for your question. With the power supply cord unplugged, the main control DA92-00593D would need to be accessed. With one meter probe at the grey wire at connection CN76, the white wire at connection CN30 would need to be tested for resistance. If the sensor measures less than 11,000 Ohms, the refrigerator thermistor DA32-00011C will need to be replaced. If the resistance measures greater than 11,000 Ohms, the main control would need to be replaced.
