Samsung Range Error Code Key Short

The Key Short error means the touch control panel has detected a sensor field that reads as continuously activated for more than 10 seconds. The most common causes are moisture on the panel surface, a stuck button condition, or a defective Assy-Touch PCB. The range triggers this error to prevent unintended operation from a stuck or shorted control input.

A power cycle reset will clear the error if the underlying cause, such as moisture on the panel, has been resolved. If the Assy-Touch PCB or sub wire is defective, the error will return after the reset because the faulty hardware will continue to signal a shorted sensor field. Always address the root cause before relying on a reset.

If the issue is moisture-related, the cost is nothing beyond your time. If the Assy-Touch PCB needs replacement, parts typically range from around 50 to 150 dollars depending on the model, with professional labor adding roughly 100 to 200 dollars on top of that. Replacing the sub wire is generally less expensive than replacing the full touch assembly.

Yes, in many cases you can resolve this error without replacing any parts. Start by thoroughly cleaning and drying the control panel surface to remove any moisture or residue. Then perform a power cycle by unplugging the range or switching off the circuit breaker for a few minutes before restoring power. If the error returns, further diagnosis or part replacement will be needed.

It is not recommended to continue using the range while this error is active. A shorted touch sensor field can cause unintended button activations, which could affect cooking functions unexpectedly. Power off the range and investigate the cause before resuming normal use.
