Samsung Range Error Code bo

The bo code on a Samsung range indicates an IGBT sensor open error on the inverter board. The sensor circuit is reading abnormally high resistance, which signals an open circuit condition to the control system. This error can occur due to a faulty inverter PCB, damaged wiring, or exposure to extremely cold ambient temperatures below 14 degrees Fahrenheit.

It is not recommended to continue using the range while the bo error is active. The code indicates a fault in the inverter board's sensor circuit, which controls power delivery to the induction elements. Operating the range in this condition could cause unpredictable behavior or further damage to the inverter module. The range should be diagnosed and repaired before returning it to regular use.

Repair costs depend on the root cause. If the issue is simply a cold environment, there may be no parts cost at all. If the inverter module PCB needs to be replaced, parts alone typically range from around $150 to $350 or more depending on the model, with additional labor costs if a technician performs the work. Getting a diagnostic estimate before committing to the repair is advisable.

Some causes of the bo error are DIY-friendly. If the range is installed in a cold location, allowing it to warm up to normal room temperature may clear the code. You can also inspect visible wiring for loose connections. However, if the fault points to the inverter module PCB after resistance testing, replacing that board is a more involved repair that requires comfort working with electronic components and disconnecting high-voltage parts.

A reset may temporarily clear the bo code, but it will return if the underlying issue is not resolved. If the error is caused by a low ambient temperature, warming the unit and resetting it may be sufficient. If the cause is a faulty inverter PCB or damaged wiring, the code will reappear after a reset because the hardware fault remains present.
