My new coach has an Atwood 6 gallon tank type water heater with both gas and electric heat. It works fine but when on gas Iíve noticed something outside of my experience. It lights and burns fine but all the while the burner is going the igniter continues to spark. Not rapidly like when lighting the burner but just twice about every three seconds. Click, click pause and repeat. I see no purpose in it and am concerned it will burn out the igniter. On the other hand it is a distinctly different mode from start up so seems intentional. Is this a normal?
Just to close the loop....called the manufacturer today and a very nice tech assured me itís a bad circuit board. Weíre on a month long snowbird trip to Florida so having a mobile service come and replace it. Seems a waste to have to hire someone else do it but itís warranty item and it seems I canít be trusted to make the call. At least itís an easy fix!
