LG Refrigerator Error Code Freezer 2nd Digit d

This code indicates a freezer fan error, meaning the main control board is not receiving a proper feedback signal from the freezer evaporator fan motor. The fault can be caused by a loose or disconnected signal wire, a motor wire that has slipped out of its connector, or a defective fan motor. The board monitors the fan through connector CN72 and expects to see between 7V and 12V on the feedback line. When that signal is missing or abnormal, this error is logged.

It is not advisable to rely on the refrigerator for food storage while this error is active. A non-functioning freezer fan means cold air cannot circulate properly, and freezer and fresh food compartment temperatures may rise to unsafe levels. Frozen food could begin to thaw, and perishables may spoil faster than expected. Address the fault as soon as possible to avoid food loss.

A reset may temporarily clear the error code from the display, but the code will return if the underlying fault is not corrected. If the fan motor is not receiving proper voltage or the feedback signal is still interrupted, the main PCB will detect the problem again during normal operation and re-log the error. A reset is only useful as a first check to see if the issue was a temporary glitch; it is not a repair.

In some cases, yes. If the cause is a loose or disconnected wire at the PCB connector CN72 or at the fan motor, reseating the connector may resolve the error without replacing any parts. You should check that the GRAY wire at CN72 pin #1 and the YELLOW wire at pin #2 are firmly seated and that no wires have slipped out of the motor connector. If voltage at CN72 reads outside 7V to 12V after reseating all connections, the fan motor likely needs to be replaced, which is a more involved repair.

If the fix is simply reseating a loose wire connector, there may be no parts cost at all, though a service call fee typically ranges from $75 to $150. If the freezer fan motor needs to be replaced, parts and labor combined generally range from $150 to $350 depending on the specific model and local labor rates. A main PCB replacement, if required, can push the total higher, often in the $300 to $600 range.
