Tech Tips

Modern Samsung refrigerators use temperature sensors (thermistors) in multiple locations to in order to monitor compartment, evaporator, ice maker and ambient temperatures. These input temperature values are used by the main control board (PCB) to control output functions such as compressor(s), fan(s), dampers(s) and defrost functions. The main board monitors the DC voltage feedback from […]

Modern Samsung refrigerators use BLDC (Brushless Direct Current) fan motors in multiple locations including the refrigerator evaporator fan, freezer evaporator fan, condenser fan, and ice room fan. Because these motors are electronically controlled, diagnosing them is different from traditional AC or simple DC motors.

When diagnosing a Samsung refrigerator, one of the most important first steps is checking the error codes. The internal self-diagnostics can save you significant diagnostic time and prevent unnecessary part replacements. Samsung refrigerators use the main PCB (printed circuit board) to continuously monitor inputs from thermistors, fan motors, defrost circuits, ice maker components, and communication […]
