LG Dryer Error Code bC2

The bC2 code on an LG dryer indicates an incorrect button state has been detected by the control system. This means the dryer's display PCB is sending an unexpected signal, such as a button appearing to be pressed when it is not. The fault is tied to the user interface board and its connection to the main control board. Diagnosing it starts with checking whether the display PCB is loose, shorted, or physically damaged.

It is generally not recommended to continue operating the dryer while bC2 is active, since the error indicates a control panel fault that could cause unpredictable behavior. A shorted display board could potentially affect other control functions. Resolve the fault before resuming normal use.

A power reset, performed by unplugging the dryer for several minutes and then restoring power, may temporarily clear the bC2 code if the fault was caused by a transient signal issue. However, if there is an underlying hardware problem such as a shorted display PCB or a stuck button, the code will return once the dryer powers back on. A reset alone is not a permanent fix for a hardware fault.

Some cases of bC2 can be resolved without replacing parts by reseating the ribbon cable or connector on the display PCB, which requires removing the dryer's front panel or top panel depending on the model. If the board itself is shorted or a button switch has failed, the display PCB will need to be replaced, which is a moderate difficulty repair for someone comfortable working with appliance electronics. Always disconnect power before opening the dryer cabinet.

If the fix is simply reseating a loose connector, there is no parts cost involved. If the display PCB needs to be replaced, the part typically costs between $50 and $150 depending on the specific model, and professional labor can add $80 to $200 on top of that. Diagnosing the exact cause first can help you avoid paying for unnecessary parts.
