I think the Kenmore is a Rheem product, but the market changes very fast.
Intellivent control indicates that water heater has a blower on top of heater that communicates with the gas control valve to coordinate combustion.
Rheem recommends the burner assembly be cleaned no less than once a year by trained service technician who has the tools and experience.

Newer gas water heaters, both tank and tankless are maintenance heavy because of energy and safety standards, and because of new electronic controls. Tankless require more frequent attention.

If problem is going to cost more than $330, then install new gas water heater yourself from local box store. I recommend avoiding electronics, and blowers, and tankless so you can hold down costs and maintain the unit yourself.

Water heater electronics and energy factor are good initial selling points, but all costs are energy, and repairs, service and parts of more sophisticated machines can cost more than the $1 to $8 saving you can expect under best circumstance.
