I have a kenmore economizer 5 that is at least 5 years old that will not light. I tried for over 5 minutes to light this with no success. I can hear and smell the gas as I try to ignite it but nothing happens. Some of the connections are somewhat corroded. Will I need a new hot water heater and connections? Any information on this would be more than quite helpful.
Since you're messing with gas, I would have a repair guy look at it. The corrosion may be a big problem if is deep. Surface rust is not a problem. As for not lighting, if you have a pilot light, it's sensor has gone bad. The sensor is a small metal rod with a tube or wire connecting with the gas valve. The sensor sits in the middle of the pilot light flame. The sensor tells the valve that the pilot light is burning so it is safe to send gas to the burners. If the sensor is bad, the repair is quick and simple.
