Samsung Range Error Code to

The "to" error code on a Samsung range stands for top sensor open error. It indicates the control board has detected an open circuit in the top temperature sensor circuit. This can be caused by a disconnected wire, a failed sensor, a defective Touch PCB, or ambient temperatures below 14 degrees Fahrenheit.

Using the range while the to error is active is not advisable. The top sensor provides temperature feedback to the control system, and operating without accurate sensor data can result in improper temperature regulation. It is best to resolve the error before resuming normal cooking use.

Resetting the range by cycling power may temporarily clear the error code, but the code will return if the underlying problem is not corrected. A reset does not fix a failed sensor, a broken wire connection, or a defective Touch PCB. Proper diagnosis at the CN03 connector is needed to identify and resolve the actual cause.

A knowledgeable DIYer can check the wiring connections at the CN03 touch pad connector and measure the top sensor resistance against the provided resistance chart. If the resistance matches and wiring is intact, the Touch PCB assembly needs replacement, which is a more involved repair. If you are not comfortable working with appliance electronics, a qualified technician is recommended.

Repair costs depend on the root cause. If the fix is simply reseating a loose wire connector, there may be no parts cost at all. Sensor replacement parts typically fall in the range of $20 to $80, while a replacement Touch PCB assembly can range from $60 to $200 or more. Adding professional labor costs generally brings the total to between $100 and $350 depending on your location and the parts required.
