A line that will not hold temperature, a fryer that will not light, or a dishmachine that will not drain is diagnosed on the equipment, not from a description over the phone.
Gas equipment is left alone if there is a gas smell. The rest of the line can be discussed once the building is safe.
If you smell gas, leave the area and contact 911 or your gas utility.
