Girard GSWH-1M no hot water

I've had issues with this unit before as is typical however now I have no hot water at all. I've verified the 12v going into and out off main switch. From that point I'm unable to trace. I do know that the blower operates each time hot water is on but within 30 seconds turns off. There is no ignition or flame from what I see. Although LP has is on and all other gas appliances operate properly. Any suggestions???

Don't have any knowledge for the Girard water heater but here is the manual which should help.

same here

Mine is doing the same thing. Started yesterday. I've not investigated the cause as of yet.

Are you sure there's no flame? It's pretty hard to see. There's a small circular opening about 1/4" diameter to "sight" the flame through. When the blower turns on, check for power and continuity on the sail switch. It could be stuck and making the unit think the blower isn't working. The Girard tech folks will step you through finding the issue.

I had the symptom. The problem was the arrow-shaped flange inside the exhaust. It sticks in the forward position, which cuts off the flame. I lubricated the hinge on which it is mounted and used alcohol to clean the contacts of the two wires controlling the flange. It's been working well for the last week.

There is a tiny reset button toward the left side as you face the water heater from outside with the panel removed. (At least there is on ours.) It's about the same size as the antenna/cable button on the switch for the TV. Ours is a white button on a little white box less than an inch square. Press that. If the temperature is turned all the way up and the ambient temperature is also high, that button can pop out to protect you from too-hot water.

Look about six inches to the left of the exhaust port, and a little deeper into the W/H compartment.


Here's a link to a video that will show you where the button is located:

helferdm - That's the sail switch. If the blower is running, the exhaust pushes it outward and allows gas to flow as that tells the unit that air is flowing to remove CO, etc. If the sail switch doesn't get pushed outward, it thinks the fan is not running and it won't allow the burner to get gas. It connects to a relay in the rear upper left of the unit.

Yes sir, you are right on the money. Look at the attached photos. The exhaust obstruction is even worse with the cover attached. And, by the way the little windvane/flapper will reset when the cover is removed because of the movement of the exhaust. This makes troubleshooting tough.

Well, this little issue is corrected now.

Thanks everyone, we have been experiencing these issues. This forum helped me figure out how to get the flame going again, but now the water is scalding hot and then shuts off. It is just irritating that there is such a prevalent problem that forest River who monitors this forum does not take some proactive steps to address.
