Samsung Refrigerator Error Code 93E

The 93E code indicates a sparkling tank overflow sensor open circuit error. The refrigerator's control board is not receiving a valid signal from the sensor that monitors the sparkling water tank. The fault can be caused by a displaced sensor housing, a wiring disconnection, a connector contact problem, or a short circuit in the sensor circuit.

The 93E code relates specifically to the sparkling water system and its overflow monitoring sensor. If this error is active, the sparkling water function may be disabled or unreliable. The rest of the refrigerator's cooling functions should not be directly affected, but you should address the fault to restore proper system monitoring and prevent any potential overflow condition in the sparkling tank.

Repair costs vary depending on the cause. If the fix involves reseating a connector or repositioning the sensor housing, there may be no parts cost at all, though a service call could run anywhere from $75 to $150 or more depending on your location. If the overflow sensor itself needs replacement, parts and labor together could range from $100 to $250 or higher depending on parts availability and local labor rates.

Start by checking the voltage at ASSY PCB KIT connector CN30 from pin 1 to pin 2. The reading should be over 4.5V. If it is not, inspect the sensor housing to confirm it is properly seated, check the wiring harness for any disconnections or damage, and reseat the CN30 connector. If all wiring and connections check out but the voltage is still low, the overflow sensor itself may need to be replaced.

A reset may temporarily clear the 93E code, but the error will return if the underlying fault in the sensor circuit has not been corrected. The code is driven by an actual electrical condition, such as an open or short circuit, so a reset without repairs is only a temporary measure. Diagnose and repair the sensor circuit first to achieve a lasting resolution.
