'81 Excella MH water htr.
This past weekend, I too had a prob. w/ water heater. I pressed the optional lighter installed on the gauge panel, and I heard the heater light up. But when i went outside to check, the sparker just kept on clicking away and did not stop. I ran it for 5 minutes and still clicked, so I turned it off. Is this heater supposed to click like that or was it a stuck sparker?
