How do you unfreeze a gas regulator?

To unfreeze a gas regulator, first, turn off the gas supply to prevent any hazards. Then, gently warm the regulator using a heat source such as a hairdryer set to a low setting, or wrap it in a warm towel; avoid using direct flames or excessive heat. Allow the regulator to thaw gradually, and ensure it is completely free of ice before turning the gas supply back on. If problems persist, consult a professional for assistance.
