Samsung Washer Error Code 1TC4

The 1TC4 code indicates a temperature sensor error on the upper washer, specifically detecting that the motor driver section of the inverter PBA has reached an unsafe temperature. The washer shuts down automatically to prevent damage. This error points to either a failed board component or an actual overheating condition in the inverter PBA.

No, you should not continue operating the washer while the 1TC4 code is active. The code indicates the motor driver on the inverter PBA is experiencing a high-temperature condition, and running the unit could cause further damage to the board or other electrical components. Allow the washer to cool down completely before attempting any inspection.

Repair costs will vary depending on your location and whether you use a Samsung-authorized service provider or an independent technician. Parts costs for a replacement MAIN PBA typically range from $100 to $250, and labor charges can add another $75 to $200 depending on the complexity of the installation. Getting a quote from a local appliance repair service before committing to the repair is recommended.

The recommended repair is replacement of the MAIN PBA on the upper washer, which requires working with the washer's internal electronics and properly handling circuit boards. While a knowledgeable DIYer may be able to complete this repair, incorrect handling of the PBA can cause additional damage. If you are not comfortable working with appliance electronics, scheduling a certified technician is advisable.

A power reset may temporarily clear the code and allow the washer to restart, but if the underlying cause is a failed inverter PBA or a mechanical issue causing overheating, the error will return. A reset does not address the root cause and should not be relied on as a fix. The board should be inspected and replaced as needed.
