To check a gas valve, first ensure the gas supply is turned off for safety. Inspect the valve for any visible signs of damage, leaks, or corrosion, and listen for any hissing sounds that might indicate a leak.

If you're unsure or detect any issues, it's best to consult a professional technician for further evaluation.
