Atwood heater not igniting

Our Atwood heater is not igniting. We start the furnace and the blower will start with one click, it will then blow air for a short period of time and then shut off. During this time we hear no clicking or any other sound except of the blowing air. The unit is an Atwood 8012-ll the trailer is a 2014 21' model and the heater is located under the curb side rear seat. We need some help with this challenge.

Thanks Josie and Craig

It's highly likely that it's the sail switch or debris in the burner. You can check for debris quite easily by opening the outside access panel, removing the two screws that hold on the chamber cover, and cleaning it out.

Another possibility is that the piezo that throws the spark to ignite the burner is out of position.

I would check for debris first.

If cleaning out the debris doesn't work it is an Atwood 36134 if your heater is the older style and mounted in the rear. $20 on Amazon Prime. From what has been reported this is an atypical switch and most shop owners have to order it which is why it resides in my spares bin.

To clarify, Ross is talking about the Sail Switch.

Sail Switch

This is the IPB of the switch if you want to pull the unit and look for it.

Here's the link to the spare I bought https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

So I looked under the seat and can see the unit and have looked through the front of the furnace. I'm not sure which two screws I'm looking for to access the chamber to see if it's clean. Looking through the front all wires seem to be in place and the unit seems to be very clean. I don't think the previous owner used it much. I looked outside and the only thing I see is the vent and intake cover which are riveted on. I also tried the reset switch to no avail.

You may want to stop by Chilliwack if it is the sail switch, they may have an extra one...check with them first.

We had the same experience with our heater (down to the blowing and clicking) after our kids slept in it one night over the holidays. They claimed the heater wouldn't light, even when they kept messing with the thermostat. We tried the next day and ... nada (we have the digital thermostat). Called out the repairman, expecting to have the sail switch replaced or something worse. He listened to our story, opened up the front of the furnace, pressed something and, voila ... heat. He said he "reset" the heater but I can't remember where the switch was/is --but I do remember his parting comment was something to the effect of, "Alcohol and thermostats don't mix." Maybe someone knows about the reset switch?

I also tried the reset switch clicked it a few times and nothing. While sitting here the thermostat was on and the unit tried to start same result blowing but no other clicking. Thanks Jim for suggesting going to ETI but at this point they are about 600 miles away. The unit has been used about 12 times since new so everything seems very clean. The only other thing that happened was I kicked the front cover getting up and knocked it loose and we're not sure if we used the unit since. I inspected the unit afterwards while putting the cover back in place and everything seemed fine.

I'm an idiot. My apologies. Don't know why but I was thinking the water heater's chamber. On the Everest II heater, it would require puling the unit to check.

I second the advice to have it checked by Escape if possible. It's most likely the sail switch, based on the symptoms you described. Ironically, it makes no difference whether the heater is used lightly or heavily - the sail switch can just fail.
