Default Gas won't fire on hot water heater

Hi all,

My hot water heater's been running fine with both the electric element and the gas, up until today when one of my propane tanks ran out of gas (I only had the one tank turned on for some reason and noticed I ran out while cooking on the stove...).

After turning on the other tank, I fired up the stove again to verify the gas was running. That worked fine and I went on my way...

Later though, as everyone was taking showers, I noticed I did not hear the telltale sound of the gas firing for the hot water tank. The water remained hot thanks to the electric element, but without a gas flame at work. Just to verify that the gas was fine, I switched the fridge over to propane without any problem.

I've seen posts about reset buttons and whatnot, but unfortunately am too clueless to know if a) those would apply in this situation, and b) where they're located exactly.

Any help would be greatly appreciated!

Thanks,
John

John,

There are two hot water heater reset buttons located just above the gas control valve - see attached thumbnail. Press in firmly on each button and listen for or feel a click indicating a reset.

Another item to check is the gas switch inside, located on the front of the sink cabinet. It may need to be turned off and back on in order to reset the ignition sequence.

If the water is already hot (from electric heating), the gas element won't come on since there is no need for extra heat. Both the electric and the gas heaters are on thermostats, and the thermostats don't have exactly identical settings. Sounds to me like your electric heater is set slightly higher than your gas element, so it kicks in earlier, and the gas never sees the need to come on.

Turn off the electric heater, and see if the gas keeps it hot.

Thanks for the replies guys! Bill, I think you hit it on the head -- after my wife did the dishes, I noticed the gas fired up... never occurred to me that it would not fire while the electric kept things up to temp (I always do the gas first, so I've never noticed this).

Thanks again for the help!
John
