Samsung Range Error Code OT

OT stands for Over Temperature on a Samsung range. It means the top sensor has detected that the cooktop temperature has climbed to an abnormally high level. The range triggers this code to protect internal components from heat damage. It can result from improper cookware, a failed temperature sensor, or a faulty Touch PCB.

You should not continue cooking while the OT error is active. The code indicates the sensor has detected an unsafe temperature level, and ignoring it could damage the cooktop components or create a fire hazard. Power down the range and diagnose the cause before resuming use.

If the fix is simply switching to proper cookware, there is no parts cost involved. A top sensor replacement typically costs somewhere in the range of $20 to $80 for the part, plus labor if a technician is performing the work. Replacing the Touch PCB assembly is more involved and parts alone can range from $80 to $250 or more depending on the model, with additional labor costs on top of that.

Start by checking that you are using correctly sized, flat-bottomed cookware appropriate for the burner zone. If the error clears after switching pans, no further repair is needed. If the code returns, a technician should measure the top sensor resistance against the specification chart and inspect the wiring. If both check out, the Touch PCB assembly will need to be replaced.

Resetting the range by cutting power at the breaker for a few minutes may temporarily clear the OT code, but if an underlying issue exists, the error will return once the appliance heats up again. A reset is useful for confirming whether the fault is intermittent, but it is not a repair. The root cause, whether cookware, sensor, or PCB, must be addressed for a permanent fix.
